Arduino to read off Analog Dialer

Nice use for an old phone dialer, and convert the values using an arduino. Then you could use that for something else (maybe build up a phone system with the old dialer). https://www.instructables.com/id/DIY-Analog-Dialer-to-USB-Keyboard/

Interesting review of a cloned D1 Mini Matrix Shield

I had not heard of this board before. Apparently not only does it exist to be used to easily control a Matrix LED light, but the author reviewed a clone of his board from China.

Nice CNC plotter

Only issue is part of it is homemade, but the author is using some rather expensive parts with it (pro couplers, ballbearing rod, etc). So that adds alot to the cost. https://www.instructables.com/id/DIY-CNC-Writing-Machine-Using-GRBL/

Cool grafitti robot

OK kindof a robot. The author still needs to move the skateboard. Anyways the bot writes out a message in chalk dust (from chalk spray) as you skate along. Me…Would be nice to automate that bit and I wish the … Continue reading

Simple model airplane controller

with an ESP board. Pretty nice idea. He is using the wifi chip in the ESP to control the motors on the plane

I like this crowne build

Only downside is the LED ring used is only 6 inches wide. Oh and the Acrylic was cut with a laser cutter (so if you don’t have one…). I think the design could be adapted for a …well larger head. … Continue reading

Making an automated chop saw

The author basically build a system that would cut up bar stock into smaller pieces. Why? Not sure. But if you have to make a bunch of them, this would be worth it. Whole thing is controlled by an Arduino … Continue reading

Make your own Andorian antennas

Interesting build. They rotate back and forth and an arduino is used to control them. https://www.instructables.com/id/Arduino-Powered-Andorian-Antenna/

Another simple 3D printed plotter CNC

This is like the CDROM based CNC’s but…its all 3D printed and is using servos instead of steppers. Its using the ESP for a controller and seems to be doing a pretty good job of it. https://www.instructables.com/id/Tracey-Drawing-Machine/

Cool build for a smart buoy

The build is to measure aspects of the ocean. Its a nice build but not so sure if the average person can make it (the 3D print is pretty big). I wonder if they could switch to using plumping supplies … Continue reading
