I enjoy designing and building electronics. Here I’ll document electronics projects I work on in a bit more detail than I can do on twitter. Basically this is just the same images I put on twitter, but with some more words padding them out.
Donations are never required, but are always appreciated. You can donate via Github Sponsors ❤️
MSP430 custom ezFET Lite
Summary Texas Instruments has a range of 16 bit microcontrollers, the MSP430. To program these require what they call a Flash Emulation Tool (FET).
Thankfully all their affordable development kits contain a small stripped down FET, known as the ezFET Lite. TI has open sourced this design and provide both the firmware and the schematics. I was given a tag-connect cable as a giveaway through the 43oh, MSP430 community forum....
Dell XPS13 RAM Upgrade (7390)
I’d recently bought a new XPS13 7390 (non 2-in-1) laptop. I had bought the 8GB variant, how hard could it be to upgrade?
Boson Frame Grabber Part 6
Still alive? 🪦 Yes, it’s true this project did get dropped for awhile, it’s been about 3 years since the last blog post.
Boson Frame Grabber Part 5
RTL Architecture The original version of the frame grabbing PCB used an iCE40 HX8K FPGA. This turned out to be a little small for the features I wanted to add. I managed to get it to a state where it would capture images from the Boson 320, but everything was hardwired together, and not easy to alter or reuse.
In order to improve module reuse and extendability a standard interface should be used....
Boson Frame Grabber Part 4
The new hardware for the Boson Frame Grabber will be based around the Lattice ECP5 family. Lattice make available a free IDE for this FPGA assuming you are not using a model with embedded SERDES. Since we are not, it’s perfect for our application.
