I don't know exactly when or where I got this little guy; it probably was in an assortment of parts and projects several years ago, though I'd guess it's much older. (The chip has a 1987 date on it, though that just means it can't have been made before then.) It's a very obvious homebuild, but I don't know whose. Some of the labels are heavily damaged, but the main one I believe originally read "Ear Destroyer"; the two marks on the "Frequency" scale are "Pain" and "Death". In the interest of information, I did pop a fresh 9V battery in and got it to generate a high pitched squeal whose frequency went up as the knob swung counterclockwise.

The guts are a basic 555 astable multivibrator circuit; the only really notable aspect is that it's made by wire wrapping, where all the connections are via thin insulated wires wrapped around long posts in the back. It was a very common prototyping technique for a long time, but I don't think I have anything else built using it (though I do have a wire wrapping gun somewhere in my collection).

Two of the three PCB's that make up the piece of rack gear I call my DI box.

on the left, is a clone of the EQ section from a 70s Sunn Coliseum Bass amp, Half assembled.

It is a 4 knob eq, with controls idiosyncratically (but accurately) labeled high, mid, hi bass, and low bass. the high and mid controls each have a 2 position frequency switch. The result is a very versatile, but still easy to tune tone control.

On the right is my standard line output pcb, fully assembled, except for the gain setting resistor.

this is a transformer coupled design, which uses a small power amp, to ensure it cant be overloaded. I didn't know it when I designed this, but this is almost identical to the design used by urei in the late 1970s, notably in the 1178, and la4a.

It has better isolation and a lower noise floor then a modern integrated design, and is actually cheaper then the IC solutions sold by That crop.

I used the same pcb with a different transformer as a reverb driver in my rack mount spring reverb.

If you have ever listened to my music you have heard both these circuits on synth, guitar, bass, and even my drum machines. I've also sold several identical units to local studios.

also, the spring reverb is my go to reverb now. So its on most tracks as well.

Found out my dad is still using a remote control box I built as a teen from stock Radio Shack parts, circa 1980, for the Christmas tree lights..

As I mentioned, since the power has been out for over a day, I took the household phones, laptops, and rechargable batteries to the library today to recharge them. This left my wife here without much in the way of entertainment, so before I left, she was asking if we had a portable radio around, preferably one that didn't need headphones.

This is where it comes in really handy that her stepdad sent me two electronics kits for Christmas: an AM radio, and an FM radio. (And that I built them both nearly as soon as I got them; I don't have a battery- or butane-powered soldering iron, so having them in pieces would be pretty useless.) So we set up the FM one and it's been playing music all day.

As much as we sometimes question the utility of broadcast media in a world where people keep saying "everybody has a smartphone", it's really nice to have these fallbacks, because there will always be emergencies and outages.

logically i know hacking a 3DS won't be hard and it shouldn't require much but unfortunately ever since my battery bloated i am. Paranoid

#my first 3DS (the one who had a bloated battery) is REALLY old and every time it has a problem i loose 10 years off of my life #its got a bump on the back from the bloated battery. ive opened it back up like 2 times to make sure its ok. UGHHH #the second one is fine but its my only 3DS that can properly play DS games with the bottom touchscreen #my first one registers all touchscreen inputs to the top right corner with DS games #and ive heard that hacking it can cause that problem #so im not sure i wanna hack the second one #AND TO TOP IT ALL OFF i have TERRIBLE luck with electronics!!!! #so like yeah id probably be able to know what im doing but FUCK man im not sure if i wanna risk it #at this point I'm better off asking my mom to help me do this. she's fixed my 3DS before maybe she can help with this #mossball.txt #nintendo 3ds #3ds hacking #3ds homebrew

if my colecovision arrives and doesnt work its over for me ive already went down the rabbit hole watching tons of footage of games and stuff and basically just unintentionally hyping myself up a ton and am already fantasizing abt playing games on it while listening to dancers of bali and my moog records.. oh and of course herbie hancocks mr hands.. UGH it better work

#i mean it said it does but like judging from other listings it seems its common more for them to be broken in some way than to be working #also hoping that my 7800 gamepad works perfectly with it #it also should from what ive read online but also im just a worry wart #but like goddddd if it does work and everything i seriosuly think itll be write up there with the famicom in terms of favorite consoles #like it just having such strong arcade ports from that golden era of arcade games in the u.s. #and like having tons of games sorta documenting that interlap between japanese developed games and u.s. ones like williams electronics games #even tho its missing some games not counting fan made ports that are way too overpriced it still has a very strong library #what it lacks in not including some classics it makes up for in just how consistently good the ports on it seem compared to the competition #literally blown away seeing what the galaxian port looked like like i had to look up to make sure it wasnt like a a recent homebrew or smthn

[the-hydroxian-artblog]

Are Merch Mimics capable of using assimilation offensively against humans, for self-defense and otherwise? Like, if someone tried to break a toy/game/etc they were inhabiting, could the Mimic instead pull them in?

To a degree, yeah. I should mention though that Victor isn't "in" the TV in any magical sense; spoiler alert: he's the controller Vance is holding! Hence, the eye on the controller reacting to the dialogue. The Victor on the screen is actualy a model he rigged for a homebrew game he coded the old fashioned way, which responds to whatever inputs the controller sends to the Wii.

He actually is an active member of the homebrew community, and loves to mess with electronics the old fashioned way. Almost no one on the forums knows he's a toy bird, but are impressed nonetheless with his little projects, various rail-shooter games, and weird obsession with snarky anthropomorphic birds.

Victor could technically "jump into a game" on a tv screen, but it'd be a bit of a weird process if he doesn't know how to mod the game, so it'd look more like a shitty greenscreen effect rather than anything coherent. He'd need to learn in real time how the game is coded, how to inject arbitrary code into the system while it's running, etc etc. He CAN do that because he's a fucking NERD, but it wouldn't be a quick process at all.

I should also mention, mimics have an inherent ability to create dreams, since they come about from processing the thoughts and ideas of humans. If a human bonds with a mimic, such that the mimic now knows how the human thinks, they can pull a (somewhat) willing human into the dream when the human sleeps. So to wrap this all up: what Victor could do for a game he understands inside and out is pull a human into a dream that happens to match whatever he himself experiences as currently going on in the game. Basically the ultimate VR experience, with the mimic as a middle-man. Which might be something that'll happen in the comic soon....!

So that all seems a bit convoluted, right? Here's even more worldbuilding about matter assimilation by mimics below the cut. Stop here if you don't want a headache.

The reason so many hoops would be needed to pull a human into a game world is that assimilation is much easier on inert, inanimate objects that are not currently "in use" by a thinking thing, or something that relies on constant electrical signals to function. This can be something with brainwaves, or some other kind of animation like a normal robot. A mimic can convert a CRT TV that's turned off somewhat easily, but a TV that's turned on, with particles of every kind constantly moving into and out of it, is much harder to convert.

This means that humans and biological creatures in general are also trickier to convert, though it can still happen if done gradually enough. Hence, Victor wouldn't be able to rapidly convert Vance in one fell swoop, it'd be a whole process. It's easier to just pull a human into a dream instead, and if a mimic undersrands a video game, or a story in a book really well, they can basically make the fictional world into an extremely lucid reality for whatever human tags along with them.

I often describe mimics as just "jojo stands if they were corporeal and could just get up and move around on their own with no user"; you know how in jojo stand battles or old stories about magic curses, if you break the curse or kill the stand before its effect becomes permanent, all of the damage is magically undone? Like if you kill Green Day, the mold stand, all of the molding just instantly stops?

Mimics who use their powers of assimilation offensively work similarly; they can project their influence to a certain range, and partially assimilate matter in that range. If you knock out or kill the mimic, however, everything reverts to normal. A human who doesn't want to get converted can basically just turn around and walk away most of the time, or shoot the mimic, so the mimic in question needs to pull off some trick to get the human to stay within range for the assimilation to fully stick. A human can still break free and get out of range even if fully converted, but it's much harder, as assimilation usually means the mimic gaining greater control over the converted object in question. The exact range and effect mimics have is again like jojo stand ranges; it varies.

Different mimics have different affinities for different things. Victor can assimilate cheap electronics fastest because he likes them and understands how they work (it's why he's a toy bird mp3 player). Az can assimilate guns, and turn ammo into weird anomalous ammo with weird effects. Zachary is a genius who can assimilate any matter, including biological matter, faster than anyone... but he's also extremely picky and hates the sight of blood, so he only uses assimilation on things he really, really likes.

If I could somehow make another read more at this point, I would. It's gonna get messy:

What a weird power and setup though, right? Why? The true nature of mimics is unknown to most of them, but the deepest lore is that the first mimics were constructs made by a people long ago, who first made them as highly advanced machines that'd recognize the thoughts of their masters to fulfill any practical desire. Need a road built? Done. Need a ship repaired? Done. With physical needs all met, the people began to turn inward, and use the mimics to illustrate their own artistic ideas. Eventually, the will and consciousness of these people were assimilated and inherited by mimics, who themselves became people. Mimics spread, altered themselves, duplicated, deviated, fused, split, and wandered around. Getting into recreational wars, manifesting horrors and delights into reality because they could.

Somehow, after the dust settled, the strongest mimics, the angels, decide to set their sights to the stars, and observe other lifeforms develop technology and their own art. Did mimics come to earth millions of years ago, and simply watched humans grow, evolving with them in-tandem? Or did humans make the first mimics, and somehow became undone and set back to the stone age? The answer to this mystery is currently known only to the oldest of mimics. Except Zachary. He's old, but didn't care to remember.

This is generally why mimics seem so compatible with humans; they were made by either them, or people who were, for whatever the reason, very much like them, flaws and all. The ability to assimilate is basically the conversion of matter into a more malleable state of information. A virtually magical power, but this was achieved not through prayers and spells, but a very human-like obsession with developing technology to the point of exerting control over molecules, then atoms, then the lowest planks of matter. The obsession with scaling every mountain and crossing through every valley. To rip the natural world apart, and hopefully, put it back together before it's too late. Angels seek to ensure humanity walks the right path there, but with human's own desires and intent honored, for better or worse.

To answer your question: yes. A mimic of Mario can pull you into the game and you can jump with him and eat shitty low poly spaghetti with him.

The process for doing that is just convoluted and complicated, and you need to get to know each other a bit first. If he tries to use it as an attack though, it either won't work, or it might just wind up giving you mild brain damage.

OdySim: The Magnavox Odyssey Simulator (Windows, 2015 onward, simulating games from 1972-1973)

It's a simulator and not an emulator because in the world's first home video game console, there was no CPU to emulate - just raw electronics. You can download it here - it'll show the manual, along with game rules, and you can download the simulators here (homebrew games will appear first, with the originals being in the 'Old versions' folder).

You can read original manuals here.

Bender (2002) by Ted Larson and Bob Allen, CA, USA. Bender is the first incarnation of the self-balancing AMPbot concept; Ted & Bob later founded OLogic to promote it.

"Bob had built some combat robots in the past, and we were both excited about working together on more interesting and complicated robotic projects where we could use all three robotics disciplines: mechanical, electrical, and software engineering. Back then, my mechanical engineering skills were severely lacking. Robot-suitable mechanical parts were hard to come by, but combat robot parts were more readily available due to their popularity on TV at the time. 

I had a pile of these parts and was eager to put something together. I remember one afternoon going over to Bob’s house to discuss the possibility of doing a collaborative robot project using this parts pile. His first comment was, “Are you crazy? You’re going to destroy your house if you build it with that stuff!” He then showed me a video of a robot that could balance on two wheels, and I thought it was amazing. Plus, it was small and probably wouldn’t destroy my house. Bob and I wondered if we could build something similar. It couldn’t be that hard, right?

Months later, in 2002, Bob and I finally had a set of electronics put together, with the right motors figured out, and we were ready to take a crack at making it balance and drive around. Then came the hard part. Building the robot was one thing, but the software challenge of making it autonomously balance on two wheels was monumental. I think it took a good three months just to get it to not fall over, and many more months to make it drive around. The first robot was named Bender after the lovable beer-drinking robot from Futurama. It fell down so much that it made sense to name it after a robot that was drinking all the time." – Ted Larson, From HomeBrew to Hasbro How two friends hacked a balancing robot and wrote a toy story of their own.

When did you first developed an extreme interest in computers and have you tried to build one?

I was 12, bored, and decided to look up what the first version of Windows looked like, which led me to Guidebook Gallery (sadly not updated anymore), and it went downhill from there.

As for building computers, I haven't tried a homebrew from scratch (my electronics skills aren't up to that and I keep getting distracted by other stuff) but I've got three regular x86 (_64) ones I've built: my main rig running an 8th gen i7, a Core 2 Quad machine with a WinXP 64 install and a broken regular XP install, and an AMD K-6...II? based off of a motherboard+CPU combo I got at a garage sale. I haven't decided what's going on it permanently but it's currently got Microsoft Neptune on it. Most of my other machines I've replaced at least one part in, or upgraded in some way, save for one of my PIIIs (it's a piece of shit that's not worth it even with a failing PSU fan), the iMacs (G3 and G4), and the 286.

Ah, again a lack of patience makes my results less than what I planned, but I do have a proper panel for my headphone amp now.

To recap, I wanted to be able to just plug headphones into my synth, so I built the dual NE5532 circuit on a scrap of perfboard and cut its original panel out of a cardboard box that held little bags of animal crackers. Since that kind of panel isn't exactly going to hold up to repeated plugging and unplugging of cables into its three jacks, I cut this panel out of a scrap of sheet aluminum, using tin snips to trim a couple of edges but mostly using nibblers, which chip out a rectangle of material roughly 6mmx3mm at a go. I wore a glove on my squeezing hand this time, so it's not all bruised like the last time I tried this, and it went much easier since I didn't need to cut any inside rectangles.

Once I had it cut out and cleaned off, it was too dark to take it outside and spray-paint it, so I grabbed a brush and a little bottle of black modelmakers' gloss enamel paint. I had to practically pour the stuff on to get a thick enough layer to be, y'know, black. Then I set it aside to dry, and when it still looked liquid after an hour, looked it up online to see the proper drying time. 48-72 hours, it said.

(Now, that may not be accurate. This is apparently a very old paint set; the box, containing 9 glass bottles of paint and a plastic tray, has a price printed on it of $4.39 and a copyright notice of 1980, so formulas may have changed dramatically since then. It's at least probably not lead paint, though it would have been made, at least in part, for painting lead figures.)

So I did what any terribly impatient person with a heat gun would have done, and ran it at the thing for five minute bursts for a couple of hours. That was all last night; the paint was dry, if perhaps not completely cured, today (after maybe 20 hours), so I went ahead and mounted the parts to it and put it in the case. It's an interesting glossy effect; it's not entirely opaque, which gives the aluminum a glass-over-metal look that I kind of like. I won't do it this way again, but I'm not displeased.

And of course, it works, which is the important thing. It'll drive either my good(ish) monitor headphones or earbuds, or provide a stereo signal to plug into an effect or recorder that wants such. It's very satisfying.

The TCI "Agneyastra", a redline offensive hacker and heatgunner.

"Originally developed as a platform for electronic warfare in extreme environments, test pilots quickly found that the Agneyastra’s heat dispersal systems were equally effective as a safety valve for out-of-band overclock procedures. Seeing an opportunity, the marketing team at Tubal-Cain pressed engineers to shift the frame’s design direction, leading to its more offensive commercial variant."

Critical Role Plays Lancer (hypothetical)

What if the core cast of Critical Role played the table top Mecha role playing game Lancer? Here are the CR cast members paired with the most entertaining mechs for their style of play:

Travis Willingham in a HORUS Balor

In the major D&D campaigns Travis has shown a preference for melee combatants who engage with dark unsavory powers. The Balor is a huge mech that eats other mechs using nanite swarms. Those same nanites probably contain the consciousness of freedom fighters-turned-terrorists-turned-into-a-hive mind. It's a perfect match! If the Balor is equipped with an A.I. called a Non-Human Person then there is a possibility that Travis's pilot-character could get eaten by his own mech!

Laura Bailey in a Harrison Armory Barbarossa

Laura apparently likes long-range damage dealers and typically those are very delicate and agile characters. It would be intriguing to see how she'd handle the Barbarossa. The Barbarossa is a tanky behemoth armed with the APOCALYPSE RAIL, an anti-warship weapon that requires the user to stay still in order to charge. It would be very interesting to see if the pilot that Laura creates would fire into a melee scrum and potentially kill her allies to achieve victory. She could play around with the anxiety her pilot would experience while screaming "Get Clear of the Blast! Firing!" Or she could role play as someone totally ruthless who justifies friendly fire with the fact that dead pilots can be flash-cloned and mechs can be salvaged.

Marisha Ray in an IPS-N Tortuga

Marisha Ray is from Kentucky. The Tortuga has Shotguns. The synergy is naturally there, you guys. Joking aside, the Tortuga would give Marisha a lot of role flexibility, she'd be able to defend her friends from enemy advance or she could push into the fray headfirst. If her pilot is tech-savvy, she could even engage in some cyberwarfare which the Tortuga is kind-of good at. Plus the Tortuga comes with a really boring A.I. that could act as the straight man for whatever jokes Marisha's character would come up with.

Talesin Jaffey in an SSC Mourning Cloak

Mr. Jaffey would probably go with a homebrewed mech if given the choice. Since I cannot imagine the Eldritch Mechanism he would craft, I am forced to prescribe him a Mourning Cloak. It is one of the few mechs capable of teleporting, which it doesn't do very precisely. There is a slight chance that Talesin might roll poorly while determining teleport distance, causing his pilot and mech to go... someplace else... and only reappear after the scene is over. He and the game master could have a lot of fun with that.

Liam O'Brien in a HORUS Goblin (warning: robo-codpiece, or maybe you like that kind of thing, IDK)

In tactical table top action, Liam shows a propensity for complexity. And nothing is more complex than the little Goblin which contains more electronics within it than is physically possible. The Goblin can hack allies to make their systems better, hack enemy systems to make them much worse, and even hack reality to make Things happen. Liam could reprise some of his favorite shticks like "I'm just a little guy, give me uppies," and "This goblin is named Nott and is my best friend."

Ashley Johnson in a Harrison Armory Genghis

In the first two major D&D campaigns Ashley played melee damage dealers and then branched out into a wildfire druid in the third. So a striker type mech that plays with fire would be consistent with her previous choices. Enter the Genghis, the carefree pyromaniacs choice of mechanized chassis. The mech builds up heat from weapons like it's Krakatoa flamethrower or a GMS Thermal Lance and then releases it in a blistering-blinding heat cloud. Incendiary damage continues burning victims until they douse themselves so Ashley can just set and forget. Finally I'd love to see what kind of pilot Ashley would come up with who would use a mech that's just as terrifying as the Balor.

Sam Riegel in an SSC Swallowtail (oh gods... please excuse the terrible mspaint job... hopefully this looks funny in a good way)

In D&D, Sam seems to like playing as unconventional back-line characters. He's been a tricky bard, a sneaky goblin/halfling rogue, and most recently a literal healbot with rage issues. So I think the Swallowtail would be a good fit for him. It's less of a mech and more of a high quality holographic movie studio on legs. It can make simulated stunt doubles of allies, use it's cameras to focus in such excruciating detail that invisible subjects are revealed, and even turn itself and everyone nearby invisible so they don't mess up the film shoot. Sam's pilot character could be some kind of propagandist or movie set manager who is infuriated by how messy actual warfare is.

Finally, Last but not least:

Mathew Mercer in an IPS-N Lancaster

I would be automatically fascinated by Mr. Mercer's interpretation of galactic human society in the year 5016u and the journey he would take his players on. But if he was a player then it would be interesting to see him controlling a Lancaster, the apex of mobile field repair platforms. Anything bad that can happen to a mech (damage, burning, hacked, immobilized) can be undone by the reliable Lancaster and it's limited pool of resources. I'm confident Mercer would be able to manage those resources wisely although it would be funny if he didn't. Role playing as his pilot, we'd get to see Matt do his best futuristic tow truck operator impression, which I think would be a very gratifying experience.
