Using 3D Printing And Copper Tape To Make PCBs | Hackaday

Thu, 29 Jan 2026 00:03:31 +0000

In a recent video [QWZ Labs] demonstrates an interesting technique to use 3D printing to make creating custom PCBs rather straightforward even if all you have is a 3D printer and a roll of copper tape.

Datacenters in space are a terrible, horrible, no good idea.

Tue, 02 Dec 2025 22:20:46 +0000

The short version: this is an absolutely terrible idea, and really makes zero sense whatsoever. There are multiple reasons for this, but they all amount to saying that the kind of electronics needed to make a datacenter work, particularly a datacenter deploying AI capacity in the form of GPUs and TPUs, is exactly the opposite of what works in space. If you've not worked specifically in this area before, I'll caution against making gut assumptions, because the reality of making space hardware actually function in space is not necessarily intuitively obvious.

8-input Video Switch

Mon, 13 Oct 2025 17:26:36 +0000

Instead of switching just four inputs, the new unit can switch 8 AV (composite) cameras and uses readily available transistors to do the switching in place of the potentially unreliable electro-mechanical relays. As a bonus, it is, of course, totally silent in use.

It Goes Both Ways! Lithium Battery Charge-Boost Kit

Mon, 21 Apr 2025 23:08:55 +0000

Make your own power bank out of any (1000 mAh or over) lithium battery! Are you a fan of bi-directional USB-C? Hey, so are we! This awesome little board goes both ways - the USB-C connector is both an input to charge a lithium battery at 1.0-1.2A and an output that provides a boosted 5V from the battery at 1.2A!

Giant USB Button – RasterWeb!

Thu, 30 Jan 2025 19:14:25 +0000

Look, I’m just going to come out and say it… this Giant USB Button is probably too big! It’s 228.6mm x 228.6mm x 120mm (which is 9″x9″ x 4.725″). The thing is, when someone asks me to build something for them, and it seems interesting, I can’t really say no. And I did say “no” this time, but mainly due to the tight deadline. I said I would need about twice as much time as requested and luckily the client came back with “We can do that!” So I got to work…
