Fresh hacks every day
Reader [Eric] sent us a powerfully informative, yet super simple hack for the MindFlex toy. Don’t worry, it’s not another worthless shock ‘game’, And it’s using an actual interface instead of the built-in LEDs.
With two wires for the serial protocol, and an Arduino, you’ll be able to view “signal strength, attention, meditation, delta, theta, low alpha, … Read the rest
[Luciano] didn’t want to drop a lot of cash into a flux and solder paste applicator so he built his own for about $5. He re-purposed a hot glue gun which you can usually find at a dollar store. After removing the heating element he inserted the body of a syringe. The plunger has been modified to use a … Read the rest
[Simon Inns] is still hard at work making USB connectivity for PIC microcontrollers easier for the hobbiest. He’s released a framework for PIC based USB devices under Windows. It includes the firmware needed for USB compatible 18F PIC chips as well as a C# class library and example programs for the Windows side of things. This goes quite a bit … Read the rest

It’s not completely an original design, but adds to the five-speed design found in a ten-year-old LEGO set. See it demonstrated in the video after … Read the rest

We checked in with [Jack] back in November to see his work with the AVR8 Soft Processor, an FPGA version of an AVR chip. Because the Arduino uses … Read the rest
