This may change things with using Teensy over Arduino UNO’s to drive motors

One of the reasons the mini like arduinos havent picked up a lot on motor control is cause they are great for one motor at a time, but multiples, not so much .  The author has written a library to … Continue reading

Interesting hack to get a cheap laser CNC to work with LaserWeb

Never heard of LaserWeb (I think its Opensource).  Anyways the author uses it to control a cheap laser engraver he got from china. Convert that Cheap Laser Engraver to 100% Open-Source Toolchain

Interesting new Arduino style

This one is interesting, much smaller than existing standard UNO boards, pin out is different too.  Oh and 32-bit ARM.  They add in WiFi or cell too.   Not so sure how well received these will be since the don’t look … Continue reading

Interesting build to help stroke folks recover

Basically its a robotic physically therapy machine for the hand.  I wonder if you could use it for other things, like, muscle memory for playing a song on a piano. Hackaday Prize Entry: Post Stroke Spasticity Rehab Helper

Make an MQTT water leak alarm

Nice build, takes an ESP and makes it into a wireless water alarm to alert your home system or phone.  Me…I would like a little more security on the device myself. http://www.instructables.com/id/ESP8266-Water-Leak-Detector-MQTT-Homie/

Make a bigger CDROM based CNC

The author basically extended the parts from a CDROM to make a bigger CNC.  Only didn’t use the CDROM motors… http://www.instructables.com/id/How-to-Make-Mini-Home-Made-CNC-Machine-Arduino28BJ/

Another DVD CNC/Laser engraver

But this one has some 3D printed parts to make it a bit easier to build.  It looks nicer than some of the homebrews I ahve seen too. http://www.instructables.com/id/Arduino-CNC-Laser-Enrgaver-From-DVD-Drive/

Interesting Rain gauge…looks easy enough…just need plans

Its an interesting rain gauge that looks pretty straight forward to make.  But the authors have not released plans yet. Low-Cost Rain Gauge Looks for Floods
