    Based on the pictures I’d expect the consistency to be rather soft and a bit like gummy.

    that's correct. The outer crust is a bit harder than the center, and the center consists of layers, which come apart easily when cutting. Not sure how to recreate those...

    Thanks for the other tips, I'll try adding starch next time I experiment with saitan. Also haven't tried to microwave it yet, usually I steam it or bake it.

    Ah yes, that's the one! Thank you so much, maybe now that I know the manufacturer i can find it somewhere.

    I've checked multiple asia stores already, will continue doing so.

    Regarding making it myself: the ingredients aren' t special, but the texture is something i don't know how to recreate

    Great, good luck with that :)

    Another thing that comes to mind: for audio purposes another technique used in ring modulators for audio effects is to use a mosfet switch to mix the signal with a square wave. This has more byproducts than mixing with a pure sine, but is a lot easier to do. Since you are downconcerting, it should not matter at all if you use a square wave, since the byproducts will all be (higher-order) harmonics of the local oscillator, which you'll filter out anyway.

    Does anyone know where to buy this specific product?

    Unfortunately I cannot find it anywhere online. It doesn't help that there is no brand name on it ;) **EDIT**: The product is http://milebv.eu/index.php/products/product/25 (thanks to [@rbn@sopuli.xyz](https://sopuli.xyz/u/rbn) for finding it!) I used to buy this at a local vegan store (veganz at Warschauerstr in Berlin), but that store closed a while ago. It was the most amazing mock duck I've had, but now I can't find it anywhere else. All I have is this picture (I don't even remember why I took it, probably to tell someone how amazing it is). As far as I recall the product was made in Taiwan, not sure if that helps. Of course, any other suggestions for tasty mock duck are welcome too, since I just love this stuff 😋

    I'm not sure I understand what you are trying to do... do you want to build a radio? Or are all your signals in the audio range?

    Anyway:

    Regarding Gilbert cells, the two popular chips are MC1496 and SA631. The 631 comes with a built-in oscillator, so it's quite handy. Unfortunately both are hard to come by these days.

    thanks, this might be just the comment I needed! Some of the screws are sunk into a very deep hole (~60mm), so it would be tough to cut a slot into those. But i'll give it a try on one of the more exposed screws, just to see if that gets me anywhere.

    EDIT: I believe I found the answer, it's something turned by this: https://ctatools.com/products/5065 Found some trash on the street that i'd like to take apart, but this screw is in my way. It's like a hex bolt, but with 5 sides, and rounded (a bit like flower petals). Here's another picture from the top: ![](https://discuss.tchncs.de/pictrs/image/73076474-2b52-4336-814d-b2145d24a5be.jpeg) I tried turning it with various tools (hard to get pliars in unfortunately), no success so far. The material is very soft, which doesn't help..

    there's no need for relays if you have low voltage

    That's a good point. Also makes me wonder if those lights will actually make a difference when it comes to plant growth, given the low power.

    It's not completely stupid. One pissible issue: when the light level is around the threshold, slight variations (think: cloud passing by) will cause the relay to switch back and forth quickly. This can be solved with some additional parts (keyword: hysteresis).

    I would recommend using a microcontroller, it makes this problem easy to solve, plus you can have more logic to trigger the lights (eg time based).

    Another thing is turning off: if it's purely based on light level, you need to make sure the sensor does not "see" any of the LED light, otherwise it thinks the sun is back up

    Reminds me of that Atlantropa plan. The idea was to drain most of the Mediterranean sea to create new land between Europe and Africa. Some German guy came up with it in the 1920s and spent like 20 years trying to convince people it's a great idea and totally doable. Unfortunately everyone was busy with other stuff back then...

    The book is about food, but mostly it talks about oxidation of the body and how various foods affect that, because that seems to be the main factor for aging and other degradation of the body. (TL;dr: eat a lot of broccoli)

    I can't recall a time when I wasn't lost in the inner solar system. Currently I'm stuck on the third dot - how do I proceed? ![](https://imgs.xkcd.com/comics/space_typography.png) ::: spoiler Alt ___ The picture shows today's XKCD comic. Transcript: [A grayed-out sentence in the Times New Roman font reads "Optimistic aliens measure space typographically". The "O" in "Optimistic" is dark black and indicated as representing the Sun (not to scale). The dots of the letters "i" in the sentence are similarly dark black. The dot in the first "i" in "Optimistic" is indicated as representing Mercury; the dot in the second "i" represents Venus; the dot in the third "i" represents Earth. The dot in the "i" in "aliens" is indicated as representing Mars. The dot in the "i" in "typographically" is indicated as representing Jupiter. A measurement bar indicates that the distance between the "O" and the third "i" in "Optimistic" is equivalent to 1 AU (astronomical unit).] [Caption below the panel:] Space tip: if you're ever lost in the inner Solar System, you can just type out the phrase "Optimistic aliens measure space typographically" in Times New Roman and use the dots as a map. :::

    How to improve my battery measurement circuit?

    I am powering a 5V microcontroller (arduino clone, atmega328p) using a 9V block and a buck converter. Now I want to let the microcontroller occasionally measure the battery voltage, so I can get an idea of how full it is. My first idea was to use a simple voltage divider: ![](https://discuss.tchncs.de/pictrs/image/9d173f1d-8412-4129-8ae1-c549a7895107.png) I've chosen the resistor values so that: - the voltage at the measure output is `< 1.1V`, to be able to use the 1.1V internal reference of the atmega's ADC - `R1 || R2 < 10kΩ`, since the atmega datasheet says "The ADC is optimized for analog signals with an output impedance of approximately 10 kΩ or less" This is great and all, but what bothers me is that this circuit will constantly draw ~100µA from the battery. So, my next thought was to add a mosfet to the divider, to switch it on only while measuring: ![](https://discuss.tchncs.de/pictrs/image/450dc371-58d0-4eb0-8f3b-4e76bf676bf4.png) This is obviously bad, because now when the mosfet is off, the ADC input sees the whole battery voltage. To address that issue, I've added a second mosfet into the measure path: ![](https://discuss.tchncs.de/pictrs/image/970e3840-fcbb-46dd-92fb-8903b89149a0.png) This works, and it does not draw any current, except while measuring. However, it's quite a few parts. So I'm curious if anyone has an idea how to do this with just a single mosfet. It seems to me like it should be possible, but I haven't figured out how. Oh, and if I'm doing something stupid here, please tell me :)

    Radial resistors... has anybody seen these before?

    I have a whole bunch of them. They are possibly a bit older (70s, 80s) judging by other contents of the junk box they are from. There are no labels of any kind, but on the top they have stripes that look hand painted. ![](https://discuss.tchncs.de/pictrs/image/2caf47a8-5ee7-4b94-957e-19c9a5cfbc19.jpeg) For at least some of them the resistance roughly corresponds to the color code. So, I'm just curious why I can't find anything about these on the internet.

    Safety tips when disassembling old electronics?

    I'm taking apart a broken tape recorder produced in the 70s (a Tesla B57, made in Czechoslovakia), to harvest some parts (inductors, switches, ...) and maybe reuse the case for some project. Which made me wonder: are there any dangers to protect myself against? I know about lead, so I'll take precautions when desoldering things. Is there anything else to be aware of? Some fumes, other toxic materials, ...? I'm not planning to connect the device to power in any way, so from an electrical perspective there should be nothing to worry about (except for caps maybe). Am I wrong?
