15A Simple and Hardy 24VDC Motor Controller

I have fun. I’ve created this original design to serve as a reversible brushed DC motor controller, and have made provisions to allow it to also be useful as a …

DC Motor Reversing Circuit

A circuit to permit forward or backward operation of a small DC motor. The direction of rotation is determined by whether +24V is applied to VFOR or VREV. If +24V is applied to both inputs or neither, the motor shuts off.

Stepped Load DC Power Supply Tester Tool

A simple circuit of my own design to permit programmable load variations on a power supply with power supply voltage feedback to permit and/or trigger recharging cycles, with voltage datalogging capability.

Crystalline Coat Hanger

My latest design of this style, wall mount coat hooks.

Unique Decoration Patterns.

I’d mentioned previously that the series of designs I’ve been working on all have uniquely generated patterns (the tray, the toothbrush holder, the knife block), here is what that looks like.

A Stylish Tray

Simple, high quality, tray design is tricky for 3D printers due to thermal warping effects, this design produces a high quality print every time.

A New Toothbrush Holder

This is a fine quality print using a similar design to the previous knife block.

I Tested My Printer With This Knife Block Design

The design files generate random pillars, so a unique version can be created with each render and print.
