This looks interesting… a linear stepper motor controller kit, open source, for CNC machines… Open Source! Circuit Diagram, PCB (Board) Layout, and PIC Software all available online. (Kit/PCB sales support PICList.com) Also: user code modifications. Standard step + direction inputs easy connection to a parallel port for up to 7 units. Use with standard CNC […]
Funny story, actually not so much – I “almost” lost all my data on my main system and a back up drive in a weird flood (water) incident and then a burnt out hard drive on the sole survivor laptop. Using a bunch of tools, hot air gun and coffee I restored about 99% of […]
If you’re building any sort of web interface for geospatial data, take a peek at OpenLayers. OpenLayers implements a (still-developing) JavaScript API for building rich web-based geographic applications, similar to the Google Maps and MSN Virtual Earth APIs, with one important difference — OpenLayers is Free Software, developed for and by the Open Source software […]
Frank writes – It’s a 3 position SPDT switch that closes (on) when tilted. Made with 3 pieces of plastic, a washer, and three machine screws + nuts. I made this switch as a hack for a cheap r/c car controller, inspired by the wiimote controlled car. I just realized, this can also double as […]
I see a MIDI project on the horizon. Operon from the openprosthetics group writes – This is a step-by-step guide on how to make your very own prototype acoustic myography sensor. That means a sensor you can use to measure muscle sounds. What is this good for? well… it is a more affordable alternative to […]
Windell writes – This morning someone asked me if it was possible to program AVR microcontrollers using their Arduino board as a programmer. I looked, and sure enough, a solution exists! This could be pretty handy, particularly if you have a Mac and/or only USB ports. Someone that is going to make this will probably […]
