@somafm Is there something up with your donations system at the moment? I'll give the PayPal route a go, but I thought you'd like to know.

A big shout out to @stfn and their excellent post, https://stfn.pl/blog/52-published-my-first-python-package-to-pypi/, about their experience publishing their first PyPI package.

That definitely tipped the scales and convinced me finish something "well enough" to get it published.

My latest blog post: Next Trains

https://mikecoats.com/next-trains/

My two-year-old loves trains so any time we can swing past the station and see them is worth the detour. This web app displays the next few arrivals and departures to help us schedule a visit. It's also my first time publishing code as a package on PyPI.

A wee scrub with some isopropyl alcohol and that'll be right as rain! I've already tested the two power stages and got nice, clean, 5v & 3.3v supplies ready to go. All that's needed now is to hook up the programming header and try to get to blinky.

I also need to remember not to guzzle coffee all day if I have any hopes of having a steady enough hand for soldering TSSOP-20.

Friday Evening Project:

Next Trains

My two year old loves trains - obviously - so any time we can swing past the station and see them is worth the detour. This is a simple web app that calls a Rail Data Marketplace API getting the next few arrivals and departures to help us schedule a visit. I then spruced it up a bit with a fun font to make it look a bit like a real Departures board.

My latest blog post: Reverse Engineering a VanMoof e-shifter – Part 2 – Decoding the Signals

https://mikecoats.com/vanmoof-eshifter-reverse-engineering-part-2/

Now we've tapped in to the wiring of a VanMoof e-shifter, let's work out the baud rate and format of the data being transmitted and which format of messages are being exchanged between it and the bike.

If anyone fancies putting a face or voice to the avatar, I'll be on @oshwassociation's Show & Tell live-stream this Thursday (16th January) at 4:00PM GMT.

I'll be talking about my Spy! Break! Inject! project alongside Avinash Baskaran introducing their Haptic Paddle and Luciano Fumagalli with their project, ANGELO.

Shout out to @alpenglow as well for the beautifully presented SMD soldering kits. Can’t wait to crack them open and get some practice in before my own SMD boards arrive from OSH Park.

Shout out to @revk for the most “extra” coaster on the market!

My Coaster Dev Board arrived and I’m seriously distracted by the colours pulsing in sync with the dog snoring away next to me.

@revk I notice you’ve included TC2030 footprints in your PCB designs recently; how do you find that for programming? It looks like you went for the version without locking legs; was that for size constraints and if so would you opt for the locking version if space allowed?

I’m trying to design a board at the moment and the only through hole component I’ve left is my pin header block for programming. PCBA would be much easier if I could ditch the headers.

Done! I've stepped outside of my comfort zone and submitted a talk proposal for @oshwassociation's Open Hardware Summit 2025 in Edinburgh. 🤞

My latest blog post: Reverse Engineering a VanMoof e-shifter – Part 1 – Connectors and Connections

https://mikecoats.com/vanmoof-eshifter-reverse-engineering-part-1/

The most common and dreaded complaint for VanMoof owners is "Err 44". If I can reverse engineer the communications between the bike and the e-shifter, I should be able to build a replacement module that spoofs the original. Let's identify the wiring involved.

My latest blog post: Make Cisco Catalyst 2960-X switches run almost silently

https://mikecoats.com/cisco-2960x-quiet/

Cisco Catalyst 2960-X 48-port PoE switches can be had on eBay for under £100. This seems like a great deal until you power them up. They have a single blower fan and it screams; during normal operation they're unreasonably loud for most homes.

My latest blog post: Leaving WordPress for Zola

https://mikecoats.com/leaving-wordpress/

I've used WordPress to run this website for the last 4 years. Recent actions by its stewards leave me feeling that I have to move off their platform.

The first prototypes were built with the Farnell BOM and these production boards were built with the new Mouser BOM, so the parts are pretty widely interchangeable between suppliers.

My "production" Spy! Break! Inject! boards arrived from @oshpark this week.

Designed in @kicad and certified Open Source Hardware by @oshwassociation, the files are available on my @Codeberg page, https://codeberg.org/MikeCoats/spy-break-inject.
