[Bob Berg] emailed in to request that we take a look at his website. We did, and we liked what we saw! [Bob] has done a couple CNC mill conversions and documented the process quite thoroughly. The first one listed on his site is a Sieg x-3, seen above. [Bob] explains that the first thing …

Need some gears? Got a timing belt? [filespace] sent in a neat build he stumbled upon: making gears with plywood and a timing belt. Just cut out a plywood disk and glue on a section of timing belt. There’s some math involved in getting all the teeth evenly placed around the perimeter, but nothing too bad. …
GSM modem means wireless serial connections
By now, most of us have seen have seen one of those GSM to wi-fi hotspot bridges. They’re interesting devices, and being able to carry a small wireless router with you at all times is very handy. Surprisingly, we haven’t seen many builds featuring these portable wireless hotspots, something probably due to the effort in …
Displaying bubbles in mineral oil
After he saw a ‘falling water display,’ [Matt] figured he could turn that idea on its head. He built a display that uses bubbles for pixels. Even though the build isn’t complete, we love the results so far. [Matt] began his build constructing a tall, thin water tank out of acrylic. Eight solenoids were mounted …
A simple project to get you started with the Android ADK
If you just got your hands on a shiny new Android phone and are looking for a fun project to try out, you might want to check out this simple Arduino exercise that [Mike Mitchel] put together. Everyone needs a starting off point for hacking, and [Mike] thought that combining and Arduino and Android handset …
The best LED cube build we’ve seen
[Nick] wrote in telling us about the LED cube he built over the course of six months. He calls LED cubes ‘done to death,’ but [Nick] might be too humble. His 8x8x8 RGB LED cube is the best we’ve ever seen. To start his build, [Nick] built a simple 4x4x4 cube as a proof of …
Digital speedometer with an arduino
[Martyn] is restoring a 32-year-old Honda motorcycle, so when the ancient speedometer broke last year he thought it was prime time to start of a digital speedometer project. We’re loving the results so far, and would love seeing it on a nicely restored bike. Instead of the relative horror of driving 40 LEDs with a …
Reverse engineering a Futaba SBUS remote control
In the world of model aircraft, Futaba’s SBUS system is a big deal. Instead of having one servo per channel, the SBUS system allows for 16 proportional controls and two digital channels for each receiver. Basically, if you’re building an awesome plane with retracts on the landing gear and bomb bay doors, this is what you want to …
Quick and easy Arduino-powered theremin
[Martin] sent in a great guide to a simple Arduino based theremin. It’s a very small build – just a single common IC and some passive components – and easy enough to build in an afternoon. The theremin is based on a simple LC oscillator built around a 7400 quad NAND gate IC, a wire …
3D printer with insane accuracy uses a DLP projector
After years of work, [Junior Veloso] is finally getting his 3D printer project out to the public. Unlike the Makerbots and repraps we usually see, [Junior]‘s printer uses light-curing resin and a DLP projector to build objects with incredibly fine detail. One highlight of [Junior]‘s project is the development of low-cost resins. Normally, light curing resins are …
