I did think about a toaster to reflow oven project as I've got half a one on my bench. I was looking at the relay in the kit but I don't know if it is rated high enough. Perhaps a solid state switch instead?

Great posts [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-c143234f-265d-4caf-9707-bebd7556e48d/8032.contentimage_5F00_1.png:16:16]

I think the Enchanted Objects Design Challenge could also be a great source of inspiration for this one!

I've kinda upcycled parts from a fridge, before now [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-c143234f-265d-4caf-9707-bebd7556e48d/contentimage_5F00_1.png:16:16]

I needed a compressor for an airbrush, but the ones that are sold specifically for airbrushes are crazy expensive (or were, anyway -- haven't checked for a long time). Instead, I went to the scrap yard, where he had a pile of old refrigerators, and removed a compressor from one of those.

I folded over the tubes and hammered them flat, to seal it, and attached a threaded nozzle to the outlet. Fridge compressors are submerged in oil, which is excellent for long life and reliable, ultra-quiet running (which airbrush compressors can't boast), but it turns out they also tend to spit a bit of oil when they're running! So I put some gauze inside the nozzle, which solved that nicely. Catches the oil, but doesn't affect the pressurised air. Needs changing very occasionally, but I can live with that.

The other problem is having it running when the airbrush is off -- nowhere for the compressed air to go. I initially looked at some release valves from a compressed air suppliers, but in the end, I just drilled a very tiny hole in the side of the nozzle instead. Only like a pin's width, using a PCB drill bit. It doesn't affect the pressure when the airbrush is running, but it gives the air somewhere to escape when it's turned off.

Total cost, around £6, including the nozzle!
