Managed to build a new lithium battery for a nice looking vintage torch, replaced the old hot wire bulb with an LED one. Works a treat, and will have around 12 hours run time.
Here is my janky soldering fume extractor that went from really janky->semi acceptable. I was able to get a custom made air purifier cheaply from the thrift store. Scrapped The UV lamp in it and added 2 AC fans and a activated charcoal filter and it is working great.
That’s good, mine just has the carbon and filter material from a box of fish tank stuff… There is a filter media called Purigen that can be recharged, so no more throwing charcoal away when it’s done. I may go with the same sort of system, but only really wanted to keep the smoke away from the lens on my microscope.
Yes Farabide, it does have a filter… some active carbon foam behind some green non active filter media. it’s really quiet and the hood lets the light through. May make a duct and put a box on top of the cupboard instead, but the whole point was to stop smoke going into my microscope.
that is one good thing about this virus shit , we are forced to wear a mask all day at work . finally after 40+ years of breathing in shit like lead dust .
Here’s another one I put together with existing parts. Hopefully, it will help in during different stages of module prototyping.
As shown, poppedon, it powers up the breadboard from the terminal block connector and saves me the trouble of putting the 10μF capacitors and Schottky diodes on the breadboard. The two LEDs for the +12V and -12V rails light when the circuit is completed by the breadboard.
Switch it to the other site of the breadboard, and you can power the breadboard off your synthesizer using the 10-pin box header, so you can test your creation in situ.
Once you have soldered the prototype you can use it to interface the power between the terminal connector desk supply and the module’s 10-pin connector. In this case, the LEDs won’t light up and the capacitors and diodes will not be in the circuit, but these should be on the module already.
