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 a mini battle bot with a bottle

This was a pretty neat start of a battle bot.  Basically using a bottle as the shield for the bot.  I would be even more impressed if the author used other recycled parts too. http://www.instructables.com/id/Soda-Bottle-Combat-Robot/

Using Syringes for Hydraulics

I have seen stuff like this before.  But this is the first for me with a “R/C steam shovel”. The overall build is pretty impressive.  Not sure what hte board is used…some form of cardboard? Super Simple Hydraulics Using Syringes

Another automated turret build

This one is a bit interesting since it seems to shoot bursts out instead of single shots.  The difference from past ones is no arduino involved (RPi and a hat for motor control), and no laptop to do image processing/etc. … Continue reading

OK this is pretty funny

The author built a simple robot that climbs up a rope, and then cuts the line. Oh and falls down to the ground too. http://www.3ders.org/articles/20170702-diy-3d-printed-ropebot-can-climb-trees-and-cut-down-ropes.html

Converting a harddrive to a sander…and good info on the motors in the drive

The write up was interesting.  but what really got my attention was the information on how these DC motors work from the harddrives. https://www.instructables.com/id/Hard-Disk-Sander/ https://en.wikipedia.org/wiki/Brushless_DC_electric_motor

Make a remote control snowblower

This is a multi year build.  The author took parts from 2 snowblowers, and electric wheelchair, tossed in an arduino and built this.  I think he says the total cost was around 1200…most in the snowblower/wheelchair bit.  Me…I am tempted….but … Continue reading
