Make a laser fighter pointer

Basically this is a sock-n like game build.  I like the build overall since the 3D prints are pretty simple and could be good for automating a laser pointer https://www.instructables.com/id/Laser-Fighting-Robot/

Interesting build for an automated light switch (bluetooth)

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

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

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

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/

OK this is an interesting barmaid robot

Only 2 motors.. One to push up and get the “juice”, another to move the glass around. Open Source Barbot Needs Only Two Motors

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
