Pontus and some other members tidied up in our electronics corner yesterday. Just look how much usable space there is now! We never had so few boxes standing around in our L-room! <3
#hackerspace #electronics

The picture shows Update's electronics corner. On the left side there is a small table with soldering and lab equipment. Next to the table, a few boxes are stacked with a 3D printer looking out of the top one. On the right wall there are wooden component drawers. On the wall behind the lab table there are blankets covering the windows. Amazingly, barely anything is lying around on the floor and only four boxes are visible in the picture.

These chunky toggle switches are nice - they can have upto 4 sets of contacts, each of which seem to have a bunch of poles each. These are momentary but there are some latching. Given the 'under license from Ericsson' label I assume they came off some comms kit originally. Now, I've just got to figure out how to mount them to something other than a panel.

A pair of old toggle switches sitting on a table. They've got a metal frame and then sets of (exposed) leaf switch contacts that are pressed or released by the tilt of the central column that moves based on the toggle at the front. They have bits of wire soldered on where they were once used. One is marked 'Made By Telephone Mfg Co. Ltd under license from Ericsson Teles Ltd. Pat No 838348'.The other is marked K. Pat No 838348, N9321 MATK' One has a pleasing blue toggle, the other a pleasin…

Biodegradable electronics can break down into harmful microplastics
Northeastern University researchers have discovered that materials used in the development of transient electronics—devices designed to biodegrade at the end of their life—can break down into microplastics, casting doubt on the true dissolvability of these devices over time.

Well, fuck.
I guess my display bracket needs screws for the display driver panel to keep this from happening next time.

RGB cable - right? Red, Grey and Blue...
(And yes, they do go to the Red, Green and Blue pins)
#electronics

Three coax cables within a VGA cable, there's a red one, a blue one, and a *grey* one - hmm. There's also a few signal cables and a nice thick outer braid. In the background is the normal random crap on my bench.

Tracked down the programmer and the TL866 adapter that I'll need to program the 27C322 with. Even found a few 27C322 EPROMs on the soldering workbench which means everything should be good to go for getting this custom cart back in good working order.

It's one thing to build something like this following a tutorial. It's a whole other thing to try to understand how it works. Time to dig into some data sheets and Arduino library code.

This air quality sensor breakout board from Adafruit just measured the PM 2.5 AQI as 59 outside my front door (which isn't that great), but it matches exactly what AirNow.gov is currently reporting.
The AirNow.gov numbers are based on multiple sensors and modeling, so I really had no idea how close they would be.
Now I have to figure out a way to use the board that doesn't require taking my laptop outside.
