big buoy has been deployed ~2 weeks ago and I just got to feed the satellite data into an influxdb/grafana server which was a long overdue first for me.

I'm now waiting for the moment everything goes wrong 4000km away

Did not anticipate breaking an SMA connector on the antenna wire. Had to fix with whatever I had in hand.
I think it works because this is an active antenna so signal is not too low here.

Remaining solution was to buy an sim808 module and UART it to the system.

Back to Dakar for more shenanigans.

From time to time, I try to grow vegetables I mostly ate, just to see what comes back. I had some pretty interesting results in the past with actual yield.
Here is an red cabbage I had some luck with, which may be promoted soon to decoration plant actually.

It seems to have been available under different names and dang, this one looks so slick. It even has an eprom emulator.

A while ago I was thinking of buying something like a minipro to play with some eeprom I have but I ended up finding this relic in my lab ! ​
I managed to find a manual online, it is about 40 year-old and has a z80 inside. I gave it a quick test and it seems to work though you have to select the right eprom model for your memory, it's a bit hit or miss for now. Anyway RS232 is there so I don't see why it couldn't be of use.
