Making your own water level detector

Posted on August 7, 2021 by robertwilkie

Interesting build for an arduino to detect the level of a given water supply. Not so sure I would make one of these as a 6 pack of commercial ones costs $11. Still an interesting build. https://www.instructables.com/Building-an-Arduino-Water-Level-Detection-Sensor/

Nice coil winder

Posted on August 6, 2021 by robertwilkie

Using an arduino and 2 stepper motors, the author build a coil winder. Not sure what the author is using it for, but I was thinking it could be adapted for making coils for wind power generators. https://www.instructables.com/GRBL-Based-Coil-Winder-From-Water-Pipe/

Interesting automated wire cutter

Posted on August 5, 2021 by robertwilkie

OK unless I was doing some sort of mass project, I don’t think I would build this. But its a neat build overall if you have a bunch of wire you needed cut into certain lengths and colors. One addition … Continue reading →

Nice drawbot, not sure where the author got the mounts

Posted on July 31, 2021 by robertwilkie

I like this build, but…no idea where the mounts came from for the motors and arduino. I didn’t find even some drawings for the. Maybe this is going to be a kit? https://www.instructables.com/DIY-Arduino-Drawing-Robot/

Cool USB tester

Posted on July 28, 2021 by robertwilkie

basically it tests USB cables using an arduino (mega) as the controller. It reminded me of the old network cable testers I used to have. Actually I googled to see if there was something like this for USB, only found … Continue reading →

Neat jumping dress

Posted on July 8, 2021 by robertwilkie

The author uses a motion sensor to show movement with the dress. Also has a nice “meteor” option too (like a screen saver one). Most of the materials the author uses are from adafruit, which provides nice “kit” like materials … Continue reading →

Interesting cheap multi switch automation setup

Posted on July 7, 2021 by robertwilkie

OK I definately will not make this build. Neat looking where the author uses a stepper to “move” a servo across a row of light switches to turn them on and off. https://www.instructables.com/Cheapest-Plug-Play-Room-Automation-Setup/

Another Kinetic Sand Art Table

Posted on June 30, 2021 by robertwilkie

Another nice build. I like how the parts are all 3D printed so you do not need to make any custom stuff. I like how he uses fake leather as a buffer between the magnet and the steel ball to … Continue reading →

Cool beer tray

Posted on June 29, 2021 by robertwilkie

The author uses an arduino to control the LEDS to give the tray a nice light affect. Gives me some ideas for other serving trays. https://www.instructables.com/Rainbow-LED-Roulette-Beer-Tray/

Making a measuring wheel

Posted on June 28, 2021 by robertwilkie

Neat build, basically you “roll” the wheel along a distance to get a measurement. Uses an ATiny for the controller. https://www.hackster.io/john-bradnam/measuring-wheel-cf26b6
