Doug Nelle uses this incredibly cheap tripod to support his 5″ f/5 refractor telescope. The wooden structures are constructed out of oak. Doug has inserted dowels into the tops of the tubes to keep them from collapsing under load. If you want to build one for yourself [yo_tyler] suggests checking local thrift stores. permalink

[Dr. Iguana’s] experience moving from jobs powered by disposable Alkaline cells as well as linear regulators to recycled Lithium Ion cells using the buck regulators seen above may serve as an motivation to make the shift in your own projects. The recycled cells he’s speaking about are pulled out of larger battery packs. As we’ve seen in […]

[Jan Ostman] has been pushing the limits of noise synthesis on the lowly AVR ATMega microcontrollers, as well as his latest two job is so adorable that we just had to compose it up. The miniTS shares the exact same fundamental sound-generation firmware with his previous TinyTS, which we’ve covered right here before, however adds […]

I don’t know why fidget spinners are only getting popular now. They’ve been selling like hotcakes on Tindie for a year now, and I’ve been seeing 3D printed versions around the Internet for practically as long. Nevertheless, fidget spinners — otherwise known as a device to turn a skateboard bearing into a toy — have become […]

This deathstar like ball is actually an autonomous surveillance camera. [Basil] wrote in to tell us about it. The body is custom designed for the project, then 3d printed. It can be dropped anywhere, as it is battery powered for up to a month, and communicates via cellar networks. It checks an email folder once […]

This self balancing robot still uses just two wheels, but it’s balancing very differently than we’re used to seeing. Where many of the projects use a form element that’s similar to a Segway, this works just like a bicycle. but it doesn’t need to keep the front and rear wheels spinning to stay upright. In […]

the blue board seen above is the guts of a product called the eeColor Color3. It was created to act as a pass-through between your television and HDMI source device. It boasts the ability to adjust the color saturation to suit any checking out conditions. But [Taylor Killian] could care less about what the thing was […]

LEGO parts are plastic. 3D printers make parts out of plastic. So the transitive home tells us that a LEGO 3D printer should be able to recreate itself. This one’s not quite there yet, mostly because it doesn’t use plastic filament as a printing medium. look close and you’ll probably recognize that extruder as the […]

[Fabian.E] wanted to light up the rims on his bike, but didn’t want to shell out a bunch of clams to get it done. He came up with this system which uses magnets and reed switches to light up one arc or each bicycle wheel. He calls it the lightrider and it’s based on the revolights concept. […]

The 2013 IEEE international conference of Robotics and Automation was held early in May. Here’s a video montage of several robots shown off at the event. looks like it would have been a blast to attend, but at least you can draw some inspiration from such a wide range of examples. We grabbed a half-dozen […]
