Just found december's #chipofthemonth, which is a 80x120 px 40 k(!) fps high-speed camera sensor with digital readout that sells at ~5 € a piece on digikey. Apparently by cutting down the exposure window, this thing can go up to 260 kfps. I wonder what you could do with a cheap, high speed camera sensor like that. According to the datasheet, apparently "gamer mouse frontend" is one of its applications. I might just get a few to try. The devkit is ~70 €.

Hey #electronics folks. Here's my situation. I got a wintertime project this week, and it's a busted diving light. Its driver PCB self-immolated inside the light's head. Here is what I managed to reconstruct; the manufacturer was an ass enough to remove markings from active components. In that regard, I got a couple questions which I can't figure out myself.

1. I get there is no figuring p/n for FETs, but maybe anyone has an idea what the controller chip might be?
2. Any idea on why D4/R17/C11 were included?
3. How should I go around finding a replacement for those FETs?

Any help will be appreciated!

Totem Stereo System, Model RR 130, circa 1970. Designed by Mario Bellini.

Mario’s work is reminiscent of Dieter Rams. Not as good, but in the same vein.

hey, people knowledgeable in #electronics , I have a dumb question:

I have a 16x16 panel of rgb leds (WS2812B ? not 100% sure, but 5v IN)

I want to pilot it with a RP Pico 2W.

If I have a beefy enough USB charger / battery, is it safe for everyone to use the usb plug of the RP Pico, and get the 5v Vin power for the panel from the Vbus pin of the RP pico? Will it provide safely the multiple amps the panel needs? (how much exactly? can't find) for full white light?

I just published the code of the first prototype of Diapasonix, a bass-like synth and MIDI controller I'm developing.
It uses the fabuolous AMY synth engine and runs on a Raspberry Pi Pico 2. Loads of presets and effects!

What an epic font choice for this datasheet #electronics

Thief River Falls' electronics behemoth in the news.

"The company already employs half of the working people in Pennington County and, despite attractive wages and perks like easy access to hunting and lake country, northwest Minnesota remains slow-growing. …

"[Founder Ron] Stordahl, now in his 80s, remains the sole owner of DigiKey. He started the company in the 1970s after creating a digital keying device for ham radio operators communicating by Morse code. For its first 20 years, it remained a relatively small business, employing a few hundred people who distributed an ever-growing selection of electronic components at the start of the personal computer age."

Should you ever be looking for information on a weird old plug or socket, or are just interested in such things, the online "Museum of Plugs and Sockets" is one of those sites that makes the Internet seem like less of a terrible mistake than usual.

The page on old British "BS 546" is unmatched, in particular: https://plugsocketmuseum.nl/OldBritish1.html

I've got a new #KiCad plugin out in the KiCad plugin manager:

KiCoil generates "twisted" planar inductors. You can make it do one- or two-layer spiral inductors, toroid inductors, and many intermediate, hybrid variants in between spiral and toroid inductors.

These hybrid types have wider traces than a single-layer spiral, and have better high-frequency behavior (parasitic capacitance and self-resonant frequency) compared to two-layer spiral inductors. And they look really pretty!

Question from @jacobcoffin , who's building a reference base for #solarpunk writers (https://wiki.slrpnk.net/writing:start):

In terms of longevity & repairability, does it make sense to lean more on through-soldered boards (vs. SMT) for simpler machines/appliances, and where does that cut off practicality-wise?
* Edit: When designing *new* things!

[I apparently have tons of thoughts that boil down to "it depends"; would love more perspectives!]
