My Modeling and Ham Radio Exploits
I’ve spent the better part of 2021 summer working with a weather station I found on Instructables, assisting to get the deep sleep functionality working. I’m using my Confluence page to collaborate with a friend in Germany on the project. I did start a couple of topics on this site where people can reach out …
Trying to build a mechanical ball clock from https://www.instructables.com/id/Marble-Clock/ New 3D printed parts Bearing housing Created a wider and better housing with a press fit for 2 roller bearings. No more super glue. Ball stop at bottom of elevator Redesigned the diameter in the stopper for a press fit to hold bearing. Existing diameter was …
6526 CIA chip has died One of the 2 CIA’s has died on my C64. I’m taking this opportunity to play with making an FPGA instance of the chip. Let’s see how this goes! Verilog starts today.
I’m building hardware and creating software to get an Adafruit feather/WINC1500 online. I’ve got some hardcoded flight aware queries to prove I can authenticate and receive JSON data. It seems that the sandard nano or pro-mini does not quite have enough memory to handle the WiFi world. Looking forward to the feather arriving! Connect to …
Working out the details on having an Arduino connect to the user port of a C64 to communicate with an NTP server and setting the system time on the C64. Long term: I’ll be connecting to flightaware.com to track my son (pilot for United Airlines) schedule. Build List C64 – a real, working Commodore 64 …
5W CW transceiver with Regenerative Receiver Kit should arrive by 3/5/17
This certainly may not be the last HF radio I have for the 40m band, but it definately qualifies for my first! I’ve ordered 2 of them for <$10 and expect to put them together next week. Stay tuned as I update this entry. 1st radio is completed, here it is! Defeciencies include: 1. Crystal …
I’m all over the place sometimes, but I’ve taken a brief left turn to re-engage on some ham radio stuff. I’m learning morse code (or re-learning). I’ve taken a software keyed project (K3NG keyer) and designed a PCB to support the project. This is my first board layout, so let’s see what happens on that …
Good Enough I’ll be outlining a project for block signaling using phototransistors and an Arduino. The solution will be responsive to moving trains The solution will use block detection for moving trains It will be “good enough” for moving trains It will be upgradeable for DCC communication, with software and an opt-coupler Shapeways A club …
