For 3D printers that aren’t already enclosed, why is easily adding a cheap and effective enclosure still not a completely solved problem? The reason is simple: unless one’s needs are very basic, enclosures are more than just boxes.
Different people …read more

nRF24L01+ module fixed about as well as it can be, by adding an appropriate capacitor on the PCB antenna, and a 1.0 uF capacitor across the power pins for good measure.
Good old nRF24L01+ wireless modules are inexpensive and effective. …read more

[TinkersProjects] experimented with making their own flexible PCB for LED modules inside a special fixture, and the end result was at least serviceable despite some problems. It does seem as though the issues can be at least partially blamed on some knockoff Kapton tape, which is what [TinkersProjects] used as …read more

The next time you find yourself in need of some large-ish plastic springs, maybe consider [PattysLab]’s method for making plastic springs out of spare filament. The basic process is simple: tightly wind some 3D printer filament around a steel rod, secure it and wrap it in kapton tape, then heat …read more

[Will Cogley]’s mechanized gauntlet concept sure has a hypnotizing look to it, and it uses only a single motor. Underneath the scales is a rod with several cams, each of which moves a lever up and down in a rippling wave as it rotates. Add a painted scale to each, …read more

Here’s a simple tip from [Andy], whose Raspberry Pi projects often travel with him outside the workshop: he suggests adding a small HDMI-to-USB video capture device to one’s Raspberry Pi utility belt. As long as there is a computer around, it provides a simple and configuration-free way to view a …read more
