Interesting build for an automated light switch (bluetooth)

Posted on November 28, 2017 by robertwilkie

I like the build.  But…not so sure I would use Bluetooth, maybe use an ESP and get wifi instead.  I like Wemo switches but they are sometimes hard to fit in older light boxes, and this could be cheaper too.  … Continue reading →

Cool Robot hands you can print out…or for under $10, buy

Posted on October 25, 2017 by robertwilkie

Nice robot hand designs.  Pretty simple and straight forward.  but if you don’t want to tie up your 3D printer, you can buy them in a kit from robotshop.com http://www.robotshop.com/letsmakerobots/parallel-mini-gripper-project

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

Posted on October 18, 2017 by robertwilkie

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 build to help stroke folks recover

Posted on September 22, 2017 by robertwilkie

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

Posted on September 12, 2017 by robertwilkie

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

Posted on August 17, 2017 by robertwilkie

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

Posted on August 14, 2017 by robertwilkie

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

Posted on July 18, 2017 by robertwilkie

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
