clever idea for a board planer

Posted on August 30, 2021 by robertwilkie

Basically taking a standard hand planer, adding long guide bars to it, and then sliding it along some boards to flatten down a bigger board. https://www.homemadetools.net/forum/board-planing-jig-video-86348?homelistings#post185195

A robot with pool noodle wheels

Posted on August 29, 2021 by robertwilkie

Nice build, the author is using a lego robot set and a star shaped pool noodle for the wheels, which gives it some good traction, and allows it to float. https://www.instructables.com/Amphibious-Robots-Using-Pool-Noodle-Wheels/

Pool beverage delivery system

Posted on August 28, 2021 by robertwilkie

Bit of an old article, but still can be made today, basically its a boat that you can RC control to deliver food and drinks to swimmers. For some reason I was looking into this stuff this weekend.

Neat hot wire CNC

Posted on August 27, 2021 by robertwilkie

Its a neat build that looks like an Ender3 base. I like how the author has “clamps” built into the base to hold the foam board in. https://www.instructables.com/Spatial-Hot-Wire-Cutting-for-Complex-Surfaces/

Nice 3D printed Hydroponic tower

Posted on August 26, 2021 by robertwilkie

Nice build. Not so sure I would do it myself, some of the Aerogarden clones are coming down alot in price and maybe an easier setup. https://www.instructables.com/DESKTOP-HYDROPONIC-TOWER/

A pretty serious nerf ball turret

Posted on August 25, 2021 by robertwilkie

The motors the author uses this are ones you find in higher end RC cars. Its a clever build and seems to shoot an move pretty fast. https://www.instructables.com/Arduino-NERF-Ball-Wireless-FPV-Sentry-Turret/

3D printed mini cooler

Posted on August 22, 2021 by robertwilkie

basically the author takes a 3D printed jet engine like design and puts it on a swamp cooler. Seems a bit of an expensive build overall. https://www.instructables.com/3D-Printed-Mini-Air-Kooler-the-OverEngineered-Edit/

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

Nice 3D moving Digital Clock

Posted on August 17, 2021 by robertwilkie

Only downside is each “digit” needs 7 servos, so for 4 digits, that 28 servos. So this could turn into a bit of an expensive build. I think the author should have added in LEDs to the build as well. … Continue reading →

Arduino Telegraph

Posted on August 13, 2021 by robertwilkie

Interesting build with old CDROM parts. The author is a little light on how to make one yourself, but thankfully has enough pictures to get the point across. https://www.instructables.com/Arduino-Powered-Writing-Telegraph/
