Electro chemical ablative chooch with my new favorite (hacked) toy.

ATX Breakout fer turning steel into brown green slime

DIY electro chemical etching tools
I'm starting to feel like a shill for this Dangerous Prototypes ATX breakout, which continues to reduce the suck and, I daresay, increase the awesome. Although, the buying process from Seeed was pure suck (paypal only corpo BULLSHIT!). Once we got past that nasty bit, it's been all goo. (Oh wait, that's not true^*)

N.B. there will NEVER be any paid adverts on this blog or YT other than what the Google (NSA?) jams on there, like it or not, for the embiggenment of all.

I will, however, be quick to request warranty replacement once I (quite inadvertently) reduce this thing to a smoking ruin. You see, dear friends, I had a little brain wave and decided to jump out the fuse for the 12V rail. Now that the overly-conservative poly fuse is out of the picture, our Prototype is proper Dangerous*. We've got the makings of an electro-chemical etching current source!

Get yourself some water, salt, random metal scraps and some paint. Jam it all together in a natty ball of wire on your crowded workbench. SHaZZaMO! Permanent marking on anything that'll chooch electrocity. Or possibly SHaZZaMO! an unstoppable toxic e-waste fire. You've been warned.


^*friggin banana posts didn't come with lock washers,  Royale pain in the ass till I hit the whole works with red locktite and Texas torque. All goo now.

*see what I did there?  Not a bad spot of bon mot-ery, eh? eh?

A simple hydraulics hack that allows you to measure huge forces easily and *ahem* safely.


I was curious of how much force a bench vise will actually put out. After a fruitless google, I set up a hydraulic rig to test the clamping force.

Record No. 8 bench vise easily capable of 2 tons clamping force. I got it up to 4600 pounds of force with little effort.  Two TONS?! That gives me an idea!

Incidentally, as you can see, we easily measure extremely high forces using only a hydraulic cylinder and a pressure gauge.
