Various useful things on Ali/eBay/whatever

If you find something interesting (not explicitly related to fetishes, because we have dedicated threads for that) on- or off-line, please post it here. Think of clever tools, computer gadgets, car accessories, etc.

Ok, I saw these things on eBay, and I thought them quite usefull.

Ebay(China) sells these remote devices for as little as 10 bucks.
These remotes come in 2, 4, all the way up to 16 channels.
I use a number of these in my raioad work and robotics projects.

Also, I bought these 24 volt to 12 volt power converters. These will handle up to 250 to 350 watts. Very handy to run 12 volt radios and lights off of Military power systems.

365nm UV flashlight
395nm UV flashlight

Both are zoomable and made from metal. I find these UV mini-torches very useful, especially if you deal with minerals, jewellery and paper money 😉

I could use a UV flashlight.

Thanks

I'm getting two. Not bad device to not have two in stock.
