   Color and the James Webb Space Telescope

   I saw Neil Degrasse Tyson talking about color on the NIRCam pictures. I thought there might be more to it, so I decided to expand on that.

   Building the most basic possible bass guitar headphone amp

   I built a thing to practice bass without bothering the neighbors. I put my videos on Peertube because it respects my freedoms. If you're unfamiliar with the platform, but want to keep up with new videos by email, please see my instructions here...

   Simple way to test serial port

   This is a simple way to make sure a serial port (RS232 or 3.3V/5V UART) is working properly. I use it all the time, maybe it's new to some people.

   Using a piezo to measure the speed of sound

   I want to be able to measure the speed of sound in liquids. Using a piezo crystal and a self built driver circuit I manage to get a proof-of-concept working.

   Using a 16x2 display by hand

   Most 16x2 alphanumeric LCD displays work the same way. They use one of many pin-compatible chips (for example, HD44780, KS0066, SED1278 or ST7066), and the only real difference is what "special characters" they have programmed in their ROM. In ...

   Testing wire termination in screw connector

   When you connect a wire using a screw terminal, there are a couple of different ways to do it. I compare a few, to see which is the most reliable if the wire can move. Source code available here: https://lorem.club/~/UglyhackLabNotes/screw-wires

    Connecting to a DS1307 clock chip over I²C

    I wanted to connect to a real-time clock for an upcoming project, but I had some trouble getting the communication to work. I've never used I²C before, so I thought it would be good to show the process of learning how this works. I remain a great...

    MEMS flow sensor

    As a followup to my "Hot Wire Anemometer" and "Modern devices flow sensor" videos, I take a quick look at a professional MEMS flow sensor. Video #10

    Followup - Mosfet breakdown voltage

    Someone commented that the shape we saw in the last video may be due to the breakdown voltage, so I put that to the test

    Driving a coil using a MOSFET

    I switch an electromagnet using a enhancement mode MOSFET - and along the way I prove I don't know what I'm doing.

    RS485 adapter for Logic Analizer

    I build a simple adapter that lets me look at RS485 busses using a logic analyzer. I left some of my stupid mistakes in the video, because I think it's important to share that no one gets anything right in one go, even simple projects like this...

    Cheap GPS from Ebay

    I ordered a $5 USB GPS receiver from Ebay, and I guess you get what you pay for. After I made the video I decided to see if I could get it working after all, but that's something for a future video
