Clever mold for cable strain relief

Posted on September 7, 2021 by robertwilkie

The author 3D prints the molds to put the cable on, and they squirts in hot glue to fill the mold in. Clever.

Nice CNC robot arm

Posted on September 4, 2021 by robertwilkie

This is a nice build since it uses a laser (no need to worry about drag of the bit), and it takes up alot smaller space than the area it can cover. Tool me a bit to understand how the … Continue reading →

Different take on a CNC plotter

Posted on August 31, 2021 by robertwilkie

Build to look like an odd robot. The good news is the base pieces are PVC pipe and are cheap and easy to come by. Downside, most of the other material used is not. Also wonder if there is a … Continue reading →

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 →
