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

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 โ 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.

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:
๐ 1300 & 1600 block of Schmeer Road
๐ 3500 block of North Victory Blvd.
This man is wanted for questioning after a series of unprovoked shootings targeting homeless people.

Hi. I'm kbob. Intro time.
I used to get paid to write software. Now that I'm retired, I do it for free. I also play with 3D printers and electronics and stuff.
I love learning, and I like to make things the hard way. I often create a #BuildThread about a project and update it for months.
