Rave Rover - Mobile LED Dance Floor

This Rave Rover is a cool build and it is very well documented so you can see all the details of the system and how it was done. They are using a ton of high power RGB LED modules that can be controlled via SPI. The control of the LEDs is being done with an Arduino. Thanks to a very sturdy frame, some pneumatics and a few wheel chair motors

CNC Maching Machining a Sphere Inside a Cube

This video shows what a machine that costs more than your average car can do. It is amazing to see something that large move with that much accuracy. The machine doing the work in this case was built by C.R. Onsrud. I wonder if they will ship us a demo unit. 🙂

Espresso Machine Microcontroller Temperature Regulation

Cameron Charles from The Adventures of Cameron Charles has a Saeco Aroma espresso machine and wanted a bit more control. Of course this means a custom PCB with an onboard microcontroller. 🙂 Have a look his Espresso Machine Microcontroller Temperature Regulation project where he shows how he takes over control of exactly how the espresso is being made. There is still a small amount of tweaking to be made but

Ducted Fan Bike

Ducted fan vehicles haven’t exactly caught on yet but they look like tons of fun. Remember the Ducted Fan Scooter we featured earlier this year? Rich Olson from Nothing Labs has built this Ducted Fan Bike, it uses 3 ducted fans that are mounted to the rear of a bike, some controls on the handlebars are used to interface with an arduino. The arduino then controls the fan speed controllers.

Bipedal Cycling Robot

You might remember the pictures and video I shot of muRata Boy and Girl at CES earlier this year.  If you liked those robots you will love the robot that Masahiko Yamaguchi built. This Bipedal Cycling Robot is quite small but when it comes to robotics small is usually more challenging. This tiny robot drives the bike just like a human does! Watch the video below to be blown away.

DIY Segway

This DIY Segway actually outperforms the real Segway in top speed. You can see a an automatic English translated version here, as you can see from the quote below the Google English translation is not bad but not perfect. The software was written in Bascom and assembler. I didn’t realize that the original Segway cost 100 million to develop, the 2000 pound build cost for this one seems like a

Solar Pop Can Heater System Build Roundup

Solar Pop Can Heating Systems are getting quite popular these days. As heating costs rise everyone is looking for ways to save on their energy bill. Most people are aware of insulating and using good weatherstripping to keep the heat in and the cold out but many don’t know about the alternate heating methods that are available. One of the alternative heating methods that is gaining some traction is capturing
