Kimchi (left) may or may not have thrown up on @fishteriously's air purifier (right) and killed it. Either way, it was dead and out of warranty, so we grabbed a multimeter and pried it open.
Ok so, the 12V power supply was working, regulated 5V power was getting where it was supposed to go, all the cables were secure and I couldn't find any shorts, but the thing was still dead. Also there was a mysterious brown goo all over it (mostly wiped off in this image).
Now, I'm a mechanical engineer, not an electrical engineer. But from what I understand, this state – where the power is good, but nothing is happening and there's something gross on it – is known as "turbo fucked."
But like, okay, once you get rid of all the bells and whistles such as "a user interface" and "selectable speed" and "digital electronics," an air purifier is just a fan, a cowl, and a filter, right? All analog components. There are plenty of places here to tap 5V power, so if I disconnect the microprocessor entirely, grab a jumper wire, and short 5V directly into the PWM input...
lol. lmao. It spins.
There we go! All put back together and working like a charm. I mean, the LED's and computer aren't connected to anything, but the fan is going and it purifies the air just fine.
I didn't like the look of the dead pcb sticking out of the top. But the wire cutters were on the other side of the room, and I hurt my fingernail last time I futzed with the ribbon cable...
Perfect. Good as new.

Obsessive Dr. Stone fans (such as yours truly) may find that a kingdom of science stencil is a very powerful thing to have, as I will demonstrate.
Fortunately for all of you, I have come up with a reliable way to draw this emblem.
You can draw it on a sheet of math paper and cut it out, or trace it to a sheet of plastic and have it last a long time.
You can stencil it on the copper sulfate! (or your preserve jars)
The simplest objects can take on a new meaning, such as a small cardboard box
How about a battery for your phone? (this one's great at running vacuum tube filaments)
It goes great on a rustic notebook or journal
Got any form of measuring or scientific instrument lacking a touch of pride? now they can belong to the kingdom of science, such as this old analog multimeter.
You can stencil it on the age meter !
Maybe you are an ethusiast who got a telescope to your name, even if it's made from stuff you found in the dump
I would love to know that somewhere out there, someone's made this. If you do, please let me know by any means, and I promise I will at least share it here in my blog.
As dumb as it may be (and I do feel kinda dumb feeling this way about horny science veggietales), deep down I want to believe that at least some of us are not just fans and we do share a vision, and despite the distance or perhaps not even knowing each other at all, we can still come together in unity under this symbol.
I'd like to believe that we can have that small connection, which feels so rare and so yearned for these days. The world is too chaotic and brutal to feel like you don't belong anywhere.

Finally...
I was looking for a really good shortwave receiver for at least a decade -an old tube equipped one of course. The problem getting one nowadays is that they were only produced in small numbers half a century (or more) ago, since then most are scrapped, botched, altered or corroded cause of bad storage -or all together. So if you have the chance getting one today you most likely will buy a 'construction site', needing hundreds of working hours for restoring it in a good working condition.
But after a looong search finally i had real luck. A big wooden crate was delivered on a pallet.
In this crate was one of the -for my opinion- ugliest shortwave receivers ever built, but at the same time also one of the best ones: a Rohde + Schwarz EK07.
Built in 1958 this one was a storage unit from the German Army. Well stored, regularly maintained and serviced, not altered, not botched, never used. So it is in nearly mint condition. It wasn't cheap but getting my hands on this was just sheer luck. Without doing anything: it's in perfect working order. No potentiometer, no switch crackles, every tube checks new -of course you can check all the tubes in the radio itself without removing them.
The manufacturer is more known for it's precision Lab-Equipment and less for it's shortwave receivers. This is also because their receivers weren't consumer or amateur gear, this was pro gear by any means. They were used in applications like coast guards or military surveillance and such. Always things where equipment costs doesn't matter -only the outcome. So back in 1958 when this unit was manufactured you could buy at least two brand new cars for the same amount of money. In exchange for this you got a masterpiece of german engineering and craftsmanship -and also an electro-mechanical nightmare if anything fails and you're not absolutely familiar with it's guts.
Fancy? No, there's absolutely nothing fancy on these. These are absolute workhorses, designed for doing an important job 24/7/365 for decades. Just take a look to that bandswich gear in the photo above. How often you have to switch over the bands until this would be worn out? Millions and Millions of times... And nope: this dark residues at that drum on the left and box below isn't mold or such. These are completely silver plated so it's just the darkened silver.
As you may see, most of the structural parts are made of die-cast and aluminum, so from the materials used it's relatively light weight. But all that built-in sturdiness and shielding adds up to staggering 147lbs/67kg. It's only a receiver, not a transmitter or a power amplifier.
Tubes... and more tubes
If you're not familiar with tube radios: your average AM (and shortwave) Radio from the 50's or 60's used 4 tubes (without the rectifier if this was a tube). Your trusty Hammarlund or Yaesu shortwave receiver from that time would have somewhat from 8 to 12 tubes -and these were quite good and sensitive receivers! This Rohde + Schwarz counts 28 tubes.
Some tubes here, some there, all fully shielded. But why the hell that much? The answer is quite simple: stability. On every count. Constant and stable gain over all bands and for a looong service time, stunningly stable VFO frequencies and all that stuff. No, they used no consumer tubes like in your TV or such. All of them are out of the 'commercial'-tube-series with a guaranteed service life of at least 10000 hours like in every aircraft of that time or such. Failing was not an option, this HAD to work.
Speaking about stability and accuracy:
this of course isn't digital stuff -it's purely analog. In the pictures below you can see the dials. Just add both frequencies and you know where you are -here on 29.630MHz or 29630kHz.
As you see: your readout is easily accurate down to less than 500Hz. So you can read at least 500Hz out of 29630000Hz. With other words the accuracy of your readout is 0.001687% in this case. Your average modern digital multimeter would be proud if it came only near to this 65 year old contraption.
Of course that large dial in the picture on the left isn't the only one. There are 12 of 'em, mounted on a drum and rotating according to the selected band. Giving you a simple S-Meter like in other shortwave receiver was of course also not possible.
Instead they provided you with a Voltmeter which displays directly the input voltage at the antenna input -and the threshold voltage for the 'Squelch' (if you have set that) which isn't a normal squelch. If activated it doesn't cut your Audio, it reduces the Gain instead with a settable time constant, so it acts more like a active noise cancelling between any signal -also between any dash and dot if you're receiving CW (Morse Code). Besides that you can choose your IF-Passband between 150Hz and 12kHz, have a absolutely stable BFO, a good Envelope Detector for AM-Reception and a perfect Audio Stage - that's all.
Speaking of the Audio Stage: 2W undistorted output power from a single end class-A is more than you need with a good speaker. McIntosh ® would call that circuit 'Unity Coupled', further a E88CC for the Audio-Preamp. We're talking about an Shortwave Radio, not an 'High-End' Audio Amplifier. Wanna take recordings of what you hear? No problem: here's your Line-Output, symmetric, 600 ohms, transformer coupled and with +10dBm (if you want) and in accordance to all Studio-Standarts. Sound quality for AM Broadcasts? With a passband switchable up to max. 12kHz for the IF better than the majority of stations can provide.
Precise?
So far so good, but what's about the heart of every shortwave receiver: the Oscillator or VFO? How stable and precisely does it beat after 65 years?
In your trusty -and quite good- Hammarlund or Yaesu amateur Radio from these days the VFO usually is equipped with two tubes: the Oscillator itself and the buffer amplifier -both sometimes also united in one bulb. If i hadn't lost track here they used 12 -and tons of other stuff. So that frickin VFO has a component count which is easily about the order of a complete shortwave receiver.
What the hell is all that stuff about -and wtf they had for breakfast back then? The answer is again simple: precision and stability.
As i said: this thing is 65 years old and i touched nothing. Of course I checked how much it's 'off' in terms of the frequency. After warming up for 20 Minutes i checked it every 1000kHz from the bottom to the top of its range. It was a bit different between all points, at some less than 50Hz and about 1kHz worst case.
My Lab-Equipment is quite good and precise, but for these low errors the tolerances of the measuring equipment has absolutely taken into account. So i made a separate measurement only for 10MHz -with the aid of a frequency standard sourced from an atomic clock. So this was 'the real thing'. After warming up for an hour i measured for 15 Minutes. The deviaton was between -717 to -722Hz. Including the error of the dial. This means frickin' 71.7...72.2ppm. PPM -parts per million! 65 years after manufacturing.... Just absolutely stunning -and with what freaking kind of equipment they had calibrated this back then??? Just have in mind: this is pure analog goodness, not a modern PLL. How the f***k they got there? Here's the clear link between a manufacturer of high-grade Lab Equipment and a shortwave receiver. I'm just stunned over the knowledge of the engineers who designed that circuit back then and the precision this was built.
All without doing anything and all it's original capacitors. Yap, i could realign that but tbh it's just wayyy to less been worth the effort. So it will stay as it is.
Nope,
you're not provided with that fancy stuff your new digital or SDR may have on board. There's no notch filter, no panoramic display -not even SSB! Why the hell they just 'forgot' all these things? The answer is easy: it's modular. The EK07 is just the 'mainframe', everything else you wanted to have can be added as external components you had to buy separately -also for tons of money of course.
Wanting SSB? Just add this:
35kg/77lbs and 18 Tubes more -to mention it's also a synchronous detector for AM is not worth the effort. Panoramic display, digital frequency counter, Teletype Adaptor, a remote control for controlling that beast over a telephone line? FM? Diversity reception?? No problem, you had just buy it. Everything of course with the same standards for precision and build quality.
The outcome...
Yea, i spent a good amount of money getting this -but in my opinion it was worth every dime. I wanted a good tube receiver and i got a really good one. Compared to upper class modern Radios it's still a very good radio. So the only thing I have to add is an external SSB/AM-Synchronous Detector. The originals are nearly impossible to get today, so i decided to build one. It's on the way and i will give you the results later. So stay tuned...

A rant about the power board in the Philips Intellivue MP2 and a basic explanation of electronics components
I accidentally broke the power board on the MP2 by feeding it 12 volts directly from my power supply. I should have known that was going to cause a problem because I already knew that it needs to communicate with the battery and if it’s not getting communication data from the battery it’s going to get confused. Thankfully the monitor still works but it no longer communicates with the battery and so I have no idea how much runtime is left. Best I can tell I think I fried either the integrated circuit circled in yellow or the one circled in blue.
The one circled in yellow is an Analog Devices LTC4100 battery management system IC. Battery management IC’s are found on all lithium batteries and they do quite a few different things. They monitor the voltage of the battery to figure out if the voltage is too high or too low and cut off the power to the circuit its powering to protect the battery and circuit from damage. They monitor the current being drawn from the battery to test for over current or short circuit which also protects the battery and the circuit it’s powering. They also control charging of the battery providing the right voltage and constant current to properly charge the battery. Some also do cell balancing which means that they monitor the voltage of each individual cell in the pack during charging to prevent overcharging of a cell. The component circled in blue is an Atmel AT Tiny 45 microcontroller. It’s responsible for communicating with the CPU on the main board and provides it with all the information it needs from the power board such as bus voltages, and errors. A microcontroller is like a computer, it has a processor, RAM, power management, and sometimes data storage all built into a single chip smaller than the size of your fingernail yet it’s more powerful than computers made 30 years ago. The Atmel AT Tiny 45/85 is the little brother of the Atmel AT Mega 328P which is the same chip the Arduino, Uno, Nano, Mini, and a few other models of Arduino use. Interestingly if you read the data sheet for the AT Mega 328P it specifically says not for use in medical devices so I’m not really sure how philips is getting away with using the AT Tiny. The reason it’s not to be used in medical devices is because they aren’t considered reliable enough that they won’t crash and possibly cause harm to the patient. If you’ve ever used an Arduino you know how prone they are to just randomly stop working. The AT Tiny might be slightly more reliable because they are only an 8 pin IC and they have significantly less RAM than the AT Mega 328P. The more I think about it, I think I probably fried the battery management IC because I don’t think the monitor would boot it didn’t have communication with the power board. Unfortunately the battery management IC is a $14 part. That’s probably for 2 reasons, 1 is it’s a genuine part from Analog Devices who fun fact makes the LTZ1000 voltage reference which is regarded as the most accurate voltage reference made today, their found in extremely high end multimeters and calibration equipment. The second reason is it’s probably a medical/ aerospace rated component which are tested to higher standards than general rated components, they also are more reliable than standard components. I’m trying to make up my mind if I want to order a replacement battery management IC or just order a new power board. The problem is that if it’s not the battery management IC that’s the problem I’m out $14. I wouldn’t need to order a new AT tiny because I can just salvage one from one of my old projects (the first generation of my DIY ventilator actually used one) , the problem is there’s no way to get the code off it and I guarantee Philips isn’t just going to give me the code. I could probably find a fake battery management IC off of LCSC or aliexpress or something but it will take months to get here and I don’t really want to wait that long. It would certainly be cheaper but I’m just better off ordering it from digikey or mouser (the 2 largest North American based electronics component suppliers) idk, if I end up replacing the battery management IC I’ll make a video of me surface mount soldering it by hand with a soldering iron so you can see how much of a pain in the ass that is.
On another note, you can tell why these power boards will run you like $700 new from Philips. It’s because all the components are high quality name brand components from reputable manufacturers. In this small section alone we can see Analog Devices, Texas Instruments, Würth Elektronik, and Fairchild semiconductor. And there’s many other companies on the rest of the board. Most consumer products use the cheapest components possible which are made by Chinese companies and tend not to be very reliable. The PCB (printed circuit board) is high quality and is 4 layers which tend to be pretty expensive to produce although they have gotten cheaper in recent years. You can also tell that this board was thoroughly inspected because there’s no cold solder joints, no solder balls, no flux residue, and no other common issues seen on consumer electronics. It was clearly human inspected which means that also adds cost.
For the people who aren’t EEs which I know is most of you, I can explain what the components circled in other colors are. The component circled in red is an inductor. Inductors are coils of wire that store energy in a magnetic field, in this case it’s part of the buck converter that converts the 36 to 56 volts of DC being put into the monitor from the external power supply to 16 volts DC that is then derived into 5, 12, +15, and -15 volts. The component circled in orange is a resistor. Resistors resist current. They have set resistances which are measured in ohms (ohms is represented with the Greek letter omega), 15kΩ in this case. The components circled in purple are tantalum capacitors. Capacitors store energy in an electric field like a battery just with way less capacity than a battery. Capacitors resist change in voltage and block DC but allow AC to pass which is the opposite of an inductor which resists changes in current and blocks AC but allows DC to pass. Capacitors, inductors, and resistors are the 3 most basic types of electronic components. The component circled in Cyan is a transistor. Transistors act like switches they and can control how much current can flow through them via another current being put into them. They are the basis of all digital electronics. CPUs, GPUs, RAM, and soild state storage are really just billions of tiny transistors and that’s why computers use binary. A 1 represents an on state and a 0 represents an off state. There are many different kinds of transistors with 3 most common categories. Bipolar junction transistors (BJTs), Field Effect Transistors (FETs), and insulated gate bipolar transistors (IGBTs). BJTs were the first type of transistor invented and are the most basic type consisting of 2 sub categories, NPN and PNP, NPN is for low side switching (it’s connected directly to ground) PNP is for high side switching (its connected directly to the positive voltage supply) All transistors have 3 leads and the different types have different names for the leads. A BJT’s leads are called Collector, Emitter, and Base. BJTs can handle the least amount of overall power out of the 3 categories. There are many different types of FETs the most common are MOSFETs which are an abbreviation standing for metal oxide semiconductor field effect transistor. MOSFETs can handle quite a bit more power than BJTs and have different properties which allow them to do that. A MOSFETs leads are called gate, drain, and source. They also have 2 types, N-Channel, and P-Channel. Another type of FET that has been a recent development is the GaNFET or Gallium Nitride field effect transistors, there’s a lot of ads for USB chargers using GaN technology which allows chargers to be smaller and more efficient because they are overall more efficient than MOSFETs. IGBTs are also a relatively recent development within the last 40 years. They can handle astronomical amounts of power compared to MOSFETs and BJTs, they are used in high power devices like Inverters and variable frequency drives.
You can’t really understand these components without a basic understanding of electrical theory IE voltage, current, power and resistance and their relationship to each other. Voltage is defined as the electromotive force needed to move electrons IE the higher the voltage the higher the overall energy that can be provided. Current can be thought of as how fast the electrons are moving. Voltage is measured in volts, current is measured in amperes but is almost always shortened to amps. Power is a representation of the total energy an electrical device consumes or can withstand. Power is measured in watts and a watt is a Joule per second, Joules being the unit of measure for energy. A good thing to know is current increases exponentially with voltage and another good thing to know is current is dependent on voltage but voltage is not dependent on current, so you can have voltage without current but you can’t have current without voltage. Power, Voltage, and Current have a mathematical relationship with each other in the form of Joule’s law. Joule’s law is P=VI where P is power in watts, v is voltage, and I is current or Power equals voltage times current. This formula is actually pretty useful in day to day life. If for example you have an electrical appliance that tells you how much current it consumes on the label but it doesn’t tell you the power it consumes. We can find out the power by using the current the device listed and then use the mains voltage of whatever country you are in, North America is 120 volts, The UK is 240 volts, Europe and Asia is 230 volts, Australia/ New Zealand is 230 volts (but depending where you are it can be 240), depending on where you are in South America and Africa it can be either 120, 230, or 240. Japan has the lowest mains voltage in the world with 100 volts. All of these systems are AC (Alternating Current) however these calculations are technically only for DC (Direct current) because DC only has real or active power while AC has Real/ Active Power, and reactive power, which is harder to calculate but doesn’t matter for households because across the world you are only billed for your real power use and not reactive power and the DC calculations work for real/ active power. The same formula can be used if you want to find out the current draw of a device from its power consumption. Voltage and current has a mathematical relationship with resistance as well in the form of ohm’s law. Ohms law is V=IR Or voltage equals current in amps times resistance in ohms.
I know that feels like a lot of information and doesn’t feel like the most basic information but I could literally talk about my knowledge of electronics all day and still not explain everything I know. Same goes for machining, entertainment industry lighting and sound, tools in general, computers, radios, history of physics and math, physics, specific electrical and physics laws like thermodynamics, faradays law, electromagnetism, and a ton of other weird things like the US national electrical code, some specific areas of chemistry and a ton more. I think I’ve mentioned before but I’m a jack of all trades, I can fix and build and design just about anything just a few of the things I can do are small electronics work, electrician work, machining, carpentry, plumbing, sewing, entertainment industry lighting sound and video, automotive work, coding, computer aided design, 3d printing, welding, and fabrication. Idk how I know how to do all this stuff some of it just kind of runs in my blood and a lot of it I’m self taught.
