Rode the Cetma across town a couple of times this morning with the trailer, a bike, and a bunch of random stuff. Not fun on the hills without the motor! #CargoBike #Cetma #ebike #BikeTooter

#introduction
New instance new intro!!

I'm somcak, a #librarian currently in #Ohio. I have 2 mini #dachshunds and 2 #cats. I enjoy all sorts of music, yes, even death metal on occasion!

I've been on Mastodon since October 2022, and this is my 5th server.

I use content warnings for all sorts of stuff, just trying to be considerate! I always make sure there's #AltText and #CamelCase for my own posts as well as those I boost. #Accessibility matters.
I enjoy learning about #history and #archeology, particularly the #neolithic. I'm also interested in #UrbanPlanning and how we can make communities greener. I have an #ebike and care about #CompleteStreets.

My latest blog post: VanSpoof - Prototype 2 - Echo Firmware

https://mikecoats.com/van-spoof-prototype-2-firmware-1/

In part 1 and part 2 of building my first VanSpoof prototype, I managed to flash the microcontroller on the PCB with a blinky demo. This time round, let's see about sending and receiving some serial data.

My latest blog post: VanSpoof v1.0

https://mikecoats.com/van-spoof-v1-0/

I'm happy to announce the v1.0 release of VanSpoof. My VanMoof X3 now starts up, without an e-shifter connected, and does not show an Error 44 status! The bike thinks it's connected to a working, functional, e-shifter!

My latest blog post: VanSpoof – A-Muntzing We Will Go

https://mikecoats.com/van-spoof-muntzing/

With my first few VanSpoof prototypes assembled, I had noticed that the L78L05 was sometimes getting a little hot. Instead of knuckling down and calculating more suitable component values, I turned to the tried and tested method of Muntzing to get my power draw down.

My latest blog post: VanSpoof - Prototype 1 - Hardware

https://mikecoats.com/van-spoof-prototype-1-part-1/

Let's look at building a prototype PCB for my VanSpoof project. I really want to get better at soldering SMD components, so I'm going to try to use as few through-hole parts as I can get away with.

My latest blog post: Low Tech Prototyping

https://mikecoats.com/low-tech-prototyping/

My existing prototypes are too big to fit on the bike, so I turn to one of my favourite low tech prototyping methods; 1:1 scale models in card and fibreboard!

My latest blog post: VanSpoof - Prototype 2 - Shrunken PCBs

https://mikecoats.com/van-spoof-prototype-2-hardware/

The VanSpoof PCB has to be no bigger than 31.5 mm by 21.5 mm to fit. Unfortunately, Molex's SMD footprints are quite wide so the board needed a fair bit of layout work to make everything fit.

My latest blog post: I'm presenting at the 2025 Open Hardware Summit

https://mikecoats.com/presenting-at-ohs-2025-cta/

I'm excited to announce that in one month's time I'm presenting at @oshwassociation's Open Hardware Summit 2025. My talk's titled "VanSpoof and F**dG3ar: Reverse engineering proprietary bike components to prevent e-waste" and covers everything involved in designing replacement, open source, parts to repair VanMoof e-bikes.

#electronics #eBike #hardware #openSource #reverseEngineering #vanMoof

we're going to start an ebike gang!

We are looking for trouble, and by trouble, I mean a pretty view where we can watch the sunset, listen to birds and draw in our sketchbook.

My latest blog post: I presented at the 2025 Open Hardware Summit

https://mikecoats.com/presented-at-ohs-2025/

Apologies for the break in blogging, but I've spent the past month preparing for, and then giving, my 'VanSpoof and F**dG3ar' talk at the 2025 Open Hardware Summit.

Hey #Portland there's a guy trying to shoot homeless people in your area. It's rare that a case like this gets so much media coverage, such solid pictures of the attacker AND a $2500 bounty.

Hope y'all locate him:

📍 1300 & 1600 block of Schmeer Road
📍 3500 block of North Victory Blvd.

This man is wanted for questioning after a series of unprovoked shootings targeting homeless people.
