Sunday Meetup 29th March at the Welshmill Hub

Yes, again it’s time for our semi-regular last-Sunday-of-the-month afternoon session! We’re meeting from 14:00 til 16:00 on Sunday 29th at the Remakery/Welshmill hub.

Feel free to bring any projects you’re working on, use the tools, discuss any interesting tech you’ve been looking into, ask questions, or just catch up.

When: 2pm - 4pm Sunday 29th March.

Who: members and prospective members.

Where: The Remakery, upstairs at Welshmill Hub, Park Hill Drive, BA11 2LE . (Park Hill Drive is off Welshmill road, near the Play Park/Bump Track)

Dear Chaps, due to circumstances beyond my control, I won’t be able to make it today. My apologies.

Not many notes on today’s discussion - some talk of life as an engineer, some talk of humans and what they are like (ref: Rutger Bregman), and some talk of coding with LLM assistance, and some of cheap GPS modules. Surprisingly cheap - £10 and under (here for example)

I made notes previously about GPS which might be worth a look:

a very detailed scrolly technical backgrounder from Bartosz Ciechanowski:

GPS – Bartosz Ciechanowski

A homemade receiver for GPS & GLONASS satellites by Matjaz Vidmar

with pages on theory, on hardware (analogue and digital) and on software

Next up, Homemade GPS Receiver by Andrew Holme

front-end board plus Xilinx FPGA

and then finally, virtually no hardware at all, gypsum (link describes theory and practice)

gypsum is a homebrew GPS receiver written in Python. gypsum can carry out a position fix in less than 60 seconds of antenna readings from a cold start.

gypsum implements a GPS signal processing stack with no dependencies aside from numpy.
