Fresh hacks every day
[Jamie Mantzel] figured out his own way of 3D printing large objects without fear of warping. First a bit of background information. When using a 3D extrusion printer like the RepRap or Makerbot, prints that span a large area tend to warp. That’s because these printers lay down one thin layer of plastic at a time. If the first … Read the rest
[Markus] had been drooling over some LED panels to use as a soft light source for photography, but being a hobbyist, he didn’t want to spend a ton of money to buy them. He figured that he had enough electronics know-how to build his own panels, while saving a boatload of cash in the process.

Basilisk? Nope, just your run-of-the-mill giant serpentine robot build. This build aims to recreate Titanoboa, a prehistoric snake which measured more than fifty feet long and weighted over a ton. They’re well on their way to completing the goal, as what you see above is fully operational, lacking only cosmetic niceties which would only serve to make the beast … Read the rest

The gist of the control system is that a conductive keyboard (made of a tinned PCB) is played by making a connection with the tip of a wired stylus — hence the name. … Read the rest

We feel his pain, as the headphone port on our computer speakers has its own demonic hum rendering the jack useless to us. His solution was to build this output selector board, then control it via the network.
A relay is responsible for routing … Read the rest
[Richard] wanted to create a color profile for his computer monitor, but he wasn’t thrilled with the existing color calibration offerings he found for sale. Color calibration tools can be somewhat costly, but even more troubling to [Richard] was the fact that they are all closed source. Closed hardware and closed software can be a drag, especially when manufacturers drop … Read the rest
[Sebastian] needed a small solder oven so he bought himself a small toaster oven (Spanish, Google Translate). It’s not the kind of thing we’d make our breakfast in now, but for soldering it’s a very nice oven.
After a little bit of research on Google, [Sebastian] discovered that the best technique when dealing with reflow ovens and solder paste … Read the rest
