Interesting cheap multi switch automation setup

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/

Neat M&M sorter

Neat build, the author 3D printed the hardware and uses an arduino as the brains to sort M&M’s. https://www.instructables.com/Arduino-MM-Color-Sorter/

One fancy 3D printed camera motion control rig

Wow this is one complex build. Not so sure I would make this one, even if my printer could print the larger parts. Nice to watch the build thought.

Tennis ball launcher build

The author designed and 3D printed a tennis ball launcher for his dog to keep the dog entertained. Nice build, but two things, it currently only does one ball at a time (so needs loading cage). and second would be … Continue reading

Nice Chess playing robot

But way more work than I would do to make one. Nice build overall thought. https://www.instructables.com/id/How-to-Built-a-Chess-Robot-With-Arduino-Mega/

Using an old touchpad to control a stepper motor

Nice build with an arduino for the controller. You use the touchpad to move one way or the other, and tap to continue moving. https://www.instructables.com/id/Reuse-Old-Laptops-Touchpad-to-Control-a-Stepper-Mo/

Using a magnetic coupling for a pump

Interesting build. The motor and the pump are not physically connected, but magnets on both parts are used to “turn” the pump with the motor. This is one way to eliminate the need to seal bearing or the motor when … Continue reading

ZeroBot

I have been looking at this build. Its pretty straight forward and can be cheap (assuming you have a 3D printer) to make, under $50 anyways. https://hackaday.io/project/25092-zerobot-raspberry-pi-zero-fpv-robot#menu-description

Interesting robot wheel build

I have seen similar builds in the past, but this is the 1st one you can build yourself. Ints an interesting build as when its in wheel form, you can go faster, but the other form is good for climbing … Continue reading

A ball bearing pick and place machine

The author designed and printed out a robot arm with vacuum to move ball bearings around. Neat build and is more for the classroom than practical purposes.
