Hey #electronics .
Can I merge decoupling #capacitors ?
Pictured: 3 1µF caps in parallel.
One for VCC
One for AVCC
One is a filter for the power supplyIt feels like they are all doing the same job and occupying space for no reason. What am I doing wrong?

🔌🤖 Oh great, another #podcast about #circuits, because clearly what the world needs is more talk about #resistors and capacitors! 🎧 Meanwhile, Michał Zalewski, aka lcamtuf, is apparently so #electrifying that you'll need a surge protector just to handle his #insights. ⚡✨

Ceramic capacitor voltage sensitivity.
I looked up a Samsung 1206 22uF 25V X5R capacitor on their website.
Huge variation in capacitance against voltage. At the rated voltage the capacitance goes down by 90%.
Way more than I ever imagined! Would make a good VCO!

How #chemists turned #bourbon waste into #supercapacitors
Hydrothermal carbonization can directly convert #stillage into hard or #ActivatedCarbon. Cossio & Guzman used activated carbon as #electrodes, creating double-layer #capacitors by putting liquid electrolyte between them. Proof-of-concept devices were able to store as much as 48W/kg. Built a hybrid device, with one activated carbon electrode and one hard carbon electrode, stored as much as 25 times the energy per kg

Oddly consistent corrosion: every 16-volt electrolytic in the device, plus one 25-volt. All the others were fine (after about 44 years). Or alternatively, all but one of this brand. There doesn't seem to be corrosion anywhere else, so it's probably not flux residues; but would all these have leaked or is it something to do with the metal itself?
Anyway, this is just tidying visible problems; don't know what's functionally wrong yet.

A very informative video on the improvement of sound quality of (professional) audio equipment with capacitors.
This knowledge can also be used in improving the tone of my Bass Guitar which suffers from a 3-6dB loss of signal on the third string (D string)

I knew of two types of capacitor that had the right to their own symbol, but this 1939 manual has six pages of symbols corresponding to different types.

Just in: the long awaited 1937 sequel to the 1927 bible on capacitor production by Philip R. Coursey that I posted a while ago. Even more details, materials and production methods, but now zooming in on electrolytic capacitors. I didn't realize Coursey was the technical director of Dubilier, the first commercial manufacturer of capacitors, which I believe is still in business 105 years after it was founded.

Very timely arrival of what must be the bible on the history and materiality of capacitors, surprisingly rare, over 500 pages with more than 2000 references, published in 1927 when capacitors were high-tech. With many pictures of workers in the mica mines in India and the ladies back home who manufactured all those capacitors that kept the empire running.

There have a vertical linearity issue on this CRT I picked up last weekend. It's a Magnavox "Computer Monitor 80" with no model # on the case anywhere, but I believe it's a Philips BM7500-series, or so.
(See the bottom 3-4 lines of text vs the rest of the text on screen - vertically squished.)
Here is the service manual as close as could be found,
https://archive.org/details/PhilipsBM75xxServiceManual/mode/2up
Can anyone tell from the schematic if there is a V.LIN pot on the board somewhere that I would find upon opening the unit? I'd like to get it adjusted and use it.
If it's a caps issue, I wonder how many would need to be replaced to get it back to snuff? This display was manufactured in late 1986.

I'm designing a small circuit board which will have an STM32 microcontroller.
One document from STMicro says that the part must have two capacitors to filter the power supply, a 'ceramic' cap at 100nF, and a 'chemical' cap at 4.7uF.
Another document says they should both be ceramic caps, and the Nucleo64 evaluation board (sold by STMicro) uses ceramic caps for both.
Should I bother using a different cap for the larger value? If so, what qualifies as a 'chemical' capacitor, just electrolytics?
