I'm working on a project, it's pretty simple. It's a chip that turns a voltage into a PWM signal.

It has three channels (hence, 3 way), and I'm basically using it as a way to hook up three potentiometers to an RGB strip. Each pot will control one color of the strip. Red, Green, and Blue.

More pictures and information soon. Although I only needed a few for a couple different projects I'm working on with the kids, I made some extras and will be selling them on my Tindie store. 

Stay tuned!

Behind every complaint is a desire, and so the name of the game is my attention is this magic wand, and whatever I put it on grows. And that’s like friendship and love and music and fashion and exercise and consciousness and strength and beauty and sex and flowers and nature and traveling and family and honesty and…

A brilliant orange and red leaf sitting on a tarmac surface

One thing I have been trying to do this autumn is stop and appreciate every leaf that catches my eye. I mean, I'm not taking photos of every one. Instead, just stop and be thankful for this little transient miracle that fell to earth.

This is a documentation page for my 8-bit VCDO (Voltage Controlled Digital Oscillator) prototype I am working on!

Tonight I finally got my first prototype filter mocked up for the 8 bit VCO. Okay, technically that's not true, I've made four separate output filters so far. But they've all had problems one way or another.

The first one, a passive filter, was just too rough. Second one was alright but I lost my paper with the component values on it. Easier to just design it all over again.
