Vacation Tidbits

I’ve returned from vacation and brought back a ton of tidbits to share over the next few weeks. I left the beautiful Pacific Northwest to work on my ranch house in Meade County, South Dakota. I had a number of projects I hoped to complete while there and got through a fair portion of my…

Analog Stepper Gauge Friday night fun

Took a while to clear off the bench tonight. I got a little happy with the ORDER button last week through weekend. I’ve filled two more parts storage containers and luckily one of my new packages with another parts storage container from Amazon; I couldn’t find any locally, I hope they’re still making them. The…

The Hackers Bench Tone Sequencer

@JohnS_AZ shared his beautiful schematic of a tone sequencer [PDF] he designed with me a few weeks ago. I think he designed it for the @tymkrs ? I watched the video and it looked like a fun project, I wasn’t wrong! John’s webpage is at : http://hackersbench.com/ I was shooting for sticking this project into…

An evening of measuring inductance

I was inspired by Alan Wolke’s ( @W2AEW ) video on measuring capacitors and inductors with an oscilloscope. I tried it out and it works pretty reasonably; yeah why wouldn’t it? Anyhow, if you can do it on an oscilloscope it can be done by a microcontroller right?  I have been trying to keep myself from…

Testing an LCD with the PIC 16F1509 and the XC8 compiler

Nuts and Volts, January 2014 had an article named “The (Nearly) Universal Process Monitor”. The whole magazine had a number of Microchip PIC based articles which is rare these days, as the articles win out to other platforms such as MSP430, Propeller, and Arduino. The article is a pretty nice project but I went to…

MC1377 Memories

My first working circuit that I designed was based on the Motorola MC1377. It’s a RGB to NTSC encoder. I am pretty certain I actually still have the chip stored away in my linear/analog microchip parts storage. Apparently they are still available NOS on eBay. I can’t claim that I designed it myself; I’m certain…

Wireless Plant Soil Monitoring: The Beginning.

I saw a little probe for monitoring soil on eBay.. $1.69 and free shipping.. purchased! Okay.. its a lame little PCB with some electronics I won’t use but still, nifty. I didn’t have much on my plate today and I was pretty sore from a solid hike yesterday so I was riding the bench seat…

Preparing Enameled Wire

I am doing some experimenting with some small signal magnetics and a thought crossed my mind to ask the super-cool @tymkrs IRC channel gang if I was missing the boat on stripping enameled wire. Turns out I was…. Warning: I will not be held responsible for wives who are upset about missing emery boards. The…
