Cool infinity mirror

Also doubles as a clock. This was alot of work for the author, I wonder if he could have simplified a few steps. https://www.instructables.com/id/Make-an-Infinity-Mirror-Clock/

Cool servo tester

It provides the angle of rotation while you use a pot to change it. Nice build overall. The color display is also pretty cheap now these days ($3). Something I may need to keep in mind for the future. https://www.instructables.com/id/Servo-Tester-2/

Nice write up on using L298 with Arduino

L298’s are good motor controller (relay) chips. The author found there are not alot of good write-ups on the combining the two. Of course there are many write-ups on using shields that have this chip built in… https://www.instructables.com/id/Connect-L298N-IC-to-Arduino/

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
