Projects, thoughts and ramblings

When adding a generic-uio device to my petalinux config, in the system-user.dtsi file, in Petalinux 2023.1, I got an error: system-user.dtsi:7.1-23 Label or path AD9851_AXI_20231112_0 not found FATAL ERROR: Syntax error parsing input tree My file looked like this: /include/ "system-conf.

Very rambly, very notebook Generate the XSA hardware file. In your petalinux docker image, then petalinux-config --get-hw-description=/home/vivado/project/EBAZ4205_projects/chaff/ebaz4205_wrapper.xsa petalinux-config -c rootfs and you can set usernames, install packages, the like The FSBL is the first stage bootloader, This is some code that

I've been getting into FPGAs again. I don't want to/can't afford a real Xilinx dev board or a real programmer, so I've been using bitcoin miner control boards, in the form of a EBAZ4205 [https://github.com/xjtuecho/EBAZ4205] . This board

This is mostly a note for myself, but maybe it will eb useful. I struggled for too long to get the ILA logic analyzer up and running in Vivado for a simple project. It seemed I was missing a lot of knowledge. Here's a step-by-step in getting it

My latest project involves charging a 12V, 3S LiIon battery over a POE connection, so limited power. I want to charge the battery over a day, at around 5W, then use that power at night for radio stuff. For the POE splitter, I think I want to use 12V output,

This is a scratch pad for a small 70cm FPV transmitter. DTV is a bust. No one makes a single chip MPEG or NTSC to DVB or ATSC signal chip. Analog is easier, and the chips are kind of available. Modulator: Can use the MC44BS373 or similar (NTSC RF Modulator)

I'm getting back into quadcopters. One thing that has caught my attention is making super small, long range drones that I can power with a single 18650. I have a largish number of nearly new recycled cells, NCR18650BLs that the datasheet only specs for 7A discharge continuous, but

While the Canon Elan 7 cameras I fixed in my last post are fantastic, they utilize IR light to count sprockets. This is a problem for IR sensitive films that are actually IR, like Kodak HIE, or Ektachrome Infrared (Aerochrome). This would cause the film to fog. Additionally per https:

Lately I've been getting back into photography. One avenue I've been exploring is emulating the look of the now defunct Kodak Aerochrome film. It was a film used in surveillance, especially looking at foliage from high altitude spy planes. It renders NIR light as bright red.

At the risk of giving away details which will hurt me, here's the stackup I'm running: Traefik as a reverse-proxy, Ghost running in a docker instance Here's my file tree: Home: Docker: ghost-blog: docker-compose.yml data: config.production.json content: traefik: data: acme.json

Hello! Welcome! I'll try to do long-form documentation here, as well as photography, project progress, etc. Now that it's self-hosted, I'm not at the whim of a VPS provider who will remove a whole line of servers leaving me high and dry... I just
