SuperDuplex: An InfraRed Bootloader for Arduino…
We’ve implemented an optical infrared Arduino bootloader based on the common 38kHz infrared remote modualtion. Using the Asuro as inspiration, our bootloader goes a step further in that it works...
How to: Bread Board Arduino…
Having a couple of Bread Board Arduinos handy can really make prototyping quick and painless. And while the Bread Board Arduino has pretty much been flogged to death in every...
On the Cheap: Supported Linear Rail…
Supported linear rail can be quite expensive, at over $100 per rail per meter, not including shipping. An alternative support was theorized using 3/8″ threaded rod, drilled, tapped and screwed...
LocoMotion: MMA8453 with Interrupts…
In the previous post about the MMA8453_N0m1 library we talked about how to get the stream of raw XYZ data back from the accelerometer. In this post we will be...
How to: Compiling the Arduino Bootloader…
A project we’ve been recently working on requires a custom Arduino boot loader. Working in an incremental fashion, the first step is getting the stock Arduino boot loader to compile...
SiC LED: Half the cost, same great taste…
NoMi Design’s northern lab recently received some next generation gallium-nitride on silicon carbide LEDs. These new XBD series LEDs from Cree are promising double the lumen per dollar of existing...
CNC Half Nuts: The Smell of Melting Plastic…
After cutting down the Y axis screw for the CNC gantry router project we had a short piece of 3/4 inch Acme leadscrew remaining that was just long enough to...
