Thought it was a capacitor at first, turns out it's a Li-ion battery in the body of a capacitor!

On Semiconductor
FYI:
On Semiconductor has decided to focus all its product marketing on Electric Vehicles. They are telling non-EV customers that their support will be limited, and they will be "at the end of the line" for allocation purposes. Non-EV customers will be required to get their parts thru distribution.
The semiconductor supply chain is expected to be constrained again in late 2024/early 2025 with analog parts being of most concern. It is good to know in advance where you stand with your vendors.

Chua's circuit built from scratch without proper perfboard or oscilloscope
![]() | The circuit looks cute but a pain to build on this board, easier on a bigger one but that was all I had at the time. With an old analog scope pictures would have been better (no pixels and continous line, old doesn't always mean worse). [link] [comments] |
Frustrated electronics hobbyist. Are electronic components being scalped?
EBAY is ridiculous. Broken parts radios. $300. WTF?

Don’t throw your backup camera away try to diagnose the problem first. All it needed was cleaning the oxidized connector. (Ford 19G490 camera)

TIL that neon bulbs have not one but two different operating regions: "glow" (~60 V) and "arc" (~10 V).
I designed a ramp generator using descrete components only

Have trouble telling the difference between red and orange resistor bands? Apparently orange reacts to UV

I bult a stereo LM1875 amp. It has a flat response, and line level RIAA equalization because my shitty record player has a built-in preamp, but does not equalize.

Yesterday I was trying to figure out why my voltage regulators weren't working. Turns out I had written a wrong part number on the reel they came on, and the pinout is different... (XC6202P332 instead of XC6206P332)

Eico 488
![]() | Picked up this mess today along with a couple of eico scopes. I wouldn't call it the best use of $20, but I wasted more on less. Lol [link] [comments] |
I have a Breadboard 6502 CPU + VGA and was having a lot of trouble writing draw routines that didn't flicker. A couple unused gates and 3 added 74 series chips I already had later and now I have working hardware double buffered video! My first time...
