PIC 18F26K22 PWM+A/D with MOSFET, the start of an eScooter?

I’m considering building an electric scooter; considering it probably putting it lightly.. I have almost everything I need for it.  Interested? Why type so much when you can just watch my proof of concept! If you’re following along and want to use the same hardware (warning totally untested… ): Controller found on the TAUTC Tindie…

A review of a handful of PIC development boards

I don’t know what possessed me to make this video but I decided to go through some of the PIC microcontroller boards I have. I was inspired by my recent purchase of half a dozen of the new TAUTIC 18F26K22 development boards. This was money well spent. I think between this and the 20 pin…

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…

First try at reflow soldering with an 858D hot air station.

This is my first try at reflow soldering. It took four attempts to get it right… so you learn 3 ways not to do it ūüėČ I just got this 858D station in the mail the other day, it cost me about $70 on eBay. ) In this video I referenced¬†Jayson Tautic’s reflow example.

A tiny Si4707 WX Radio Project Update

I pulled out the weather radio project today to see what I could get done in a few hours. I was pretty close on finishing off the hardware but I fell a little short right at the end. I found I had forgotten to buy something to convert the regulated 5V to 3.3V for the…

A weekend outside..

I didn’t have a very productive weekend in the workshop. I received a ton of parts Friday and Saturday including the case to the WX radio. I started installing parts and pieces in the case. I’m always very nervous about the first drill hole.. A only made a minor error (so far) and it is…

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…
