This is a blinky ball that [David] designed, built, and programmed himself. Does it look familiar? It should, he took his inspiration from the original prototype, and the Hackerspace-produced derivative. [David's] version is not as small, or as blinky, but in our minds the development process is the real reason for building something like this. [...]

Right after “no editing whatsoever”, the “shaky camera” is the bane of YouTube viewers the world over. [David] came up with a nice solution to the problem of shaky cameras that uses gyroscopes to even out the bumps of making a great movie. Most cameras attached to moving frames – from the zip-line cameras at NFL [...]

It’s really amazing what you can find at military surplus shops. [David] just built a radiation detector out of a DT-590A scintillation probe originally made to test if Air Force bases were contaminated with Plutonium. Who says nothing good came out of massive nuclear arsenals? DT-590A / PDR-56 Gamma ray probes were made obsolete by the US Air [...]

Here’s one way to really keep the component count low. [David] developed an NES controller that doesn’t use any buttons. The copper clad has been milled to provide a pad which registers a button push based on capacitance. The board has a SIL header at the top, making it easy to plug into the Arduino [...]

Most people use pacemakers to, you know, keep their heart pumping at a steady rhythm. [David Prutchi] on the other hand has found a pretty novel use for some of the old pacemakers he has in his collection. We really had no idea that pacemakers had uses outside the world of medicine, but [David] has [...]

[David] sent in a nice project to demonstrate augmented reality with ARtoolkit and discuss the deep philosophical underpinnings of the meaning of nothingness. The good news is he was able to create a volume control button on a sheet of paper with a marker. The bad news is the philosophical treatment is a bit weak; [...]

The Arduino is an excellent first embedded development kit, provides a great introduction to electronics, and has the potential to get children into programming. [David] thinks throwing C at non-programmers isn’t the best way to learn programming, so he developed ArduBlock , a graphical programming language for the Arduino. We’ve seen a number of graphical, block-based programming [...]

When [David] moved into his new house, one of the things he noticed was that his doorbell was pretty lame. Coming from a home equipped with a solenoid and chime bell, his new wireless solid state doorbell sounded terrible to him. Crummy sound aside, the doorbell hardly ever worked properly, but alas, other projects cropped [...]

Hackaday reader [David] was looking for a cheap and easy way to spot weld copper tabs together. As he notes in his writeup, the properties of copper which are most enticing, such as high thermal capacity, make welding it all that more difficult. His home-brew method of spot welding is admittedly quick and dirty, but [...]

You know we’re all going to starve, right? If the world’s population keeps growing exponentially and food production grows linearly, we’re eventually going to find out what Soylent Green is made of. This is where [David Dorhout]‘s Prospero robot farmer comes in. [David] has come up with the idea of using small autonomous robots to [...]

We’re no strangers to POV time pieces around here, but something about them never gets old. Whether they use a ring of LEDs to draw clock hands, or an intricately cut HDD platter to replicate LCD segments, we love seeing them. [David] sent in this hard drive POV clock built by a fellow named [Kly], [...]

[David] sent in his implementation of reading a PS/2 mouse with a PIC microcontroller and some LED displays. Of course, this follows hot on the heels of using a PIC with a PS/2 keyboard so now might be the time to start digging out your old peripherals out of your junk pile. [David] began his [...]

[David] has always wanted use UV LEDs to write on a phosphorescent surface ever since saw an article about it on Make. He accidentally purchased UV LEDs when he meant to buy purple ones, so he figured that his mistake was all the reason he needed to give UV light writing a try. He built [...]

We are always looking out for smaller yet capable computers for our projects, and this newest offering by [David Braben] is looking mighty nice. [David] is the head of a UK-based games studio, but has recently been focusing on bringing small, affordable PCs to classrooms around the world. The computer, called Raspberry Pi,  is about [...]

[David] recently wrote us to share the portable Nintendo 64 he constructed with the help of the friendly people over at the ModdedbyBacteria forums. We are no strangers to N64 portables, as you may have noticed, but this one was just too good to pass up. Sheathed in a metallic blue case, this console is [...]
