Using planetary gears for more torque

Posted on August 18, 2021 by robertwilkie

The video does a good job explaining why and how you go about doing this. Its an intersting one to watch and helps explain why you would want to do this. https://www.hackster.io/news/this-split-ring-compound-planetary-gear-system-can-achieve-super-high-reductions-4f2c4e103a22

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/

Neat M&M sorter

Posted on June 18, 2021 by robertwilkie

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

Posted on May 26, 2021 by robertwilkie

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

Posted on May 19, 2021 by robertwilkie

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

Posted on September 28, 2020 by robertwilkie

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

Posted on July 15, 2020 by robertwilkie

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

Posted on April 7, 2020 by robertwilkie

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

Posted on March 30, 2020 by robertwilkie

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

Posted on March 25, 2020 by robertwilkie

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 →
