[stextbox id=’info’]The following is a sponsored post, brought to you by Altium and Mil-Max.[/stextbox] When you design a printed circuit board, you often begin with creating a schematic that will be used as a reference later in the process.

Digital volume knob fix
The volume knob in my wife’s Toyota Highlander behaved weirdly. As you turned it up or down, the volume setting would jump up or down, sometimes in the wrong direction and by an unpredictable amount. It didn’t give a linear output as you would expect. What to do? Why, take it apart of course!
Cordifying battery things
In my house, we have a ton of “batteried” devices. Having small children, in this modern age, one tends to collect a lot of toys, tools, crafts, and associated appliances that require an array of batteries. Triple- and double-As are in high demand, though 9V and even the C cells are occasionally used. Don’t even get …
Day 30: final day
This post is part of the GaSiProMo challenge. You can read more about this here. I’ve got most of the bugs ironed out in my display interface, but not all have been squashed in the driver portion. In other words, the method in which I can input text into the OsRAM is working nicely …

The state of the Arduino ecosystem
*** The following is a “bitter old engineer” rant. You’ve been warned. At this ripe old age, I have come to value most the quality of a toolchain. I’ll go a step further and say that the coherency and consistency of the umbrella that toolchain inhabits is a most prized quality. And what spurred this revelation? …
Dell OptiPlex motherboard repair
My office was liquidating a bunch of old computer equipment. In the heap, my eye was caught by a Dell box. “Hmm, what’s wrong with that computer?” And so began my next big obsession.
Sparked interests and water analogs
Today, on the way to visit friends, my daughter asked me probing questions about one of my favorite little obsessions: traffic signals.
Surround Sound Debug
For some reason, this keeps happening to me. I must be doing it wrong. But I’ve either been too stubborn or too distracted to find the better way to do it. I’ve installed surround sound wiring into my abodes at least five times (twice in my bachelor days at two different apartments , and thrice …
