My last post got more than 1k boosts! Thanks everyone! 👉 I decided to share one of my paid resources here on Mastodon for free so that everyone can have a look at my educational paper circuit projects and how my workshop kits look. Feel free to download and/or #retoot
These color-changing mushrooms are a fun party trick for grown-ups or an easy educational project for kids aged 7 and up.
And here is the super secret download link :-) voltpaperscissors.com/secretdo…

Holy shit, the PCB design of this new sensor board, called Ophanim, of CERN’s Aegis experiment just fucking slaps. Right now, there don’t seem to be many images of it on the web, but I hope to see more in the future.

#electronics #pcb #science

A circular PcB measuring about 20 cm in diameter with a grid of camera sensor dies soldered in its middle. At the outside of the PCB, there is a ring of large ceramic capacitors. There are no other components visible. The PCB has green solder mask and uses gold plating. It shows a fucking metal design around the sensor grid with several stylized eyes shown in gold plated solder mask openings. A ring around the sensors contains a Latin inscription reading “Ophanim - ex saxis homo fecit oculos per artem ingeniumque. Numc Monstrum usum est ad Universum resiscendum”. The outside of this ring contains illustrations of a hunch of angels with halos and shit wrapping around the board.

SparkFun Retired Products Archive Reference

In late 2024, SparkFun Electronics relaunched their website. They deleted roughly 20 years of archived product information, along with all associated datasheets, schematics and tutorials. Luckily, the Internet Archive's Wayback Machine has good records of the site, and I was able to recover links to 5934 deleted products. So here's the list:

Does anyone remember the old toys for the 80s and beyond?
Does anyone like old toys that they would like to hear again but also would like to have the chance to hear them in an entire new way?
Introducing the electronic toy lib!
The electronic toy library or TETL; is a passion project by a group of people that love the old toys and the fantastic sounds they make.
From direct recordings of toys that had a headphone and connectors on the boards, to recording via coils and even things like making direct boxes to directly record the toys and making recreations of what the toys would have sound like if different situations were to be in effect!
Also called the electronic toy archive, get ready to go down a wonderful adventure back to the past with: chips; tunes; and little speakers as you take a trip to the toy world!

The Electronic Toy Archive

We are a small community that enjoys electronic toys, most of which are not meant for our age group, (most of us are in our late teens to 20s), but we still like them for some weird reason.

Fun* fact in this video: the 'disposable' vapes thrown away in Britain alone contain enough lithium batteries to make 1.2 Million e-bikes.
I've been independently powering things with vape batteries that I've rescued before seeing this video. Pull out the cell, add a cheap usb charging module and you have a fully rechargeable 3.7v power source. If you need higher voltage you can put them in series and you can even get multi-cell balancing modules for next to nothing if you want to have a few in parallel for more current.
I don't trust them for anything critical, but they're great for low-budget projects as the cells are completely free. My bike lights are all powered by them (one can run a flashing bike light for a couple of weeks' use), as well as various other things that had their batteries die, or that didn't come with rechargeable batteries.
I also only charge them somewhere flameproof, though I haven't had any issues so far.

So I've been building a 100% analog polyphonic synthesizer with an unique twist. To use only vacuum tube era technology from the 1930s.

Over 300 neon gas diodes create the sound you hear. Pretty awesome for technology from 100 years ago.

Still a work-in-progress, but I wanted to post a video of it with the innards spread out across the workbench. : }

I call it the "Neon String Machine"
