Todays crap heap challenge!

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.


Also a soldering filter thing out of the case of a PC power supply and some plastic from a LCD flat screen monitor.


So, what have you been making today?

That first picture is very distracting. For some reason I just had to go in search of chocolate.

I’ve only got 2 squares left :frowning: … and I can’t go out for more. Got to find it on the 'net.

Only 2 squares? Chocolate or toilet paper?
Either one is a disaster!

Sorry, distracted by your shortage. I meant to say the torch is a great salvage and your hood is great. Does it have a filter?

Indeed! I do have a tub of caramel hot chocolate as a backup, and a milk frothing machine to make the loveliest creamy hot chocolate I’ve ever tasted. :slight_smile:

There’s a cigar advert from the 1980s that springs to mind in that situation.

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.

Janky is better than mine: non-existent. Does an open window count?

Yep, but only when it’s not raining hard and the guttering is not blocked.

I have a similar arrangement, made using bits and scraps I had laying around. I used a filter made for the ZD-153A fumes extractor.

Since I have limited desk space at home, I made it collapsible so I can store it away when I need to reclaim my desk for work.

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.
