The Dream

I've dreamed of a PCB with everything: uC, H-bridges, PSU, Lipo charger, inductive power collector, and a wirelesss device which would allow wireless uploading to the uC. A platform I could use for robotics and wearable projects alike. Most of these features I have solved, yet one...

This project continues from my previous work:

Lab LED Controller

Revising Board

This is an extension of previous work. I had finished a LED driver for the lab, hooked it up, and found it was a fire...

By default, most Arduino pwm outputs are set to about 490Hz or 980Hz. These frequencies work quite well with small dc brushed motors but can cause unwanted noise or reduce motor torque in some cases.

The frequencies are generated as a result of the clock frequency (this tutorial assumes...

Printing with transparent filament can teach a lot about how each item you print really needs its own slicing configuration. Sure, for many things a general slice config can and will work, but to get more perfect prints requires a bit of tweaking. For instance, transparent filament will expose...

working model of wireless power transmitter and receiver. The Transmitter and Receiver coils with capacitors connected to each coils, forms a tank circuits that resonantes with a frequency of f = 1/(2π√(LC)), if the two resonant circuits resonating at the same frequency and were brought to close...

Finished

I was searching for options to create joints for puppet legs and stumbled upon this very detailed website that makes CNC machining accessible to mere mortals. (While still requiring quite some work, it looks like it's doable and contains all the details and careful advice needed.)...

L ast May (2015) I found the deal too good to be true on a Prusa i3 3D printer so I had to get one. I had always said when 3D printers got under $300 I'd get one, that i3 cost $265 delivered. Of course, it was a kit and required about a week to build it, and then about 2 more weeks to get the...
