I made it a new year’s resolution to write on the blog more. Clearly, that hasn’t happened, but not without any success. I’m off to a good start on picking up and working on a few projects, and there are 4 drafts floating around here for future posts. So, the content should be a bit more consistent or at least existing in the near future. There are a few projects from 2020 that got left to rot in the drafts, and there are a few that I’ve already done in this year, so I just have to start somewhere when posting. Here are a few things kicking around that I’m hoping to make posts on:
- USB configurable computer keyboard design, programming, and fabrication
- 3D printer firmware modification and small tricks for tuning (as if there aren’t enough)
- SCPI programming for automation and testing, along with a scaleable SCPI USB hub I designed for controlling an arbitrary amount of devices over a single physical USB connection
- Laser characterization device for burning in and observing diode parameters, along with theory, schematics, and firmware
- SPICE simulation using KiCad and ngspice for smoothing the design process
- STM principles and design using a newly acquired NS1 STM controller 🙂
- Clarion APA series car audio amplifier repair
- HP 1670D LAN fun (Xwindows, FTP and TelNet)
- HP 8594E analyzer principles and neat features- plus, it’s CLIP!
- A few pinouts and reverse-engineering of things I haven’t seen anywhere else on the internet.
So, while I haven’t been writing here, I have been working on some stuff and keeping busy, just not keeping the blog busy. Plus, I realized I still have to finish up the SNES series, as well as actually reach a resolution for the RS232 printing (my new specan prints RS232 so this would be a multi-instrument tool, encouraging me to really push towards a satisfying conclusion on that)
