Gestern Gespräch mit einem Freund über #vanmoof, #eautos , #SecondSight (https://www.chip.de/news/Augenimplantate-funktionieren-nicht-mehr-Pleite-des-Herstellers_184110188.html) geführt. Er: „Für Pleiten/ Ende des Supports müsste der Code öffentlich zugänglich und nutzbar werden.“ Jep. Plötzlich sorgten die Begriffe #linux #opensource und #signal nicht mehr für Schnappatmung

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

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.

Du möchtest (m)ein #VanMoof kaufen und wohnst idealerweise in #Kiel (oder Umgebung, oder zumindest im Norden)? Dann bitte hier entlang --> https://www.kleinanzeigen.de/s-anzeige/e-bike-vanmoof-s3-1000km-gelaufen-/3064363413-217-10597

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 - 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: 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 – 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 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 - 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: 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.

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.

#intro Hi! I’m Josh, moved from Tokyo after 8 years to #Seattle with my partner Taku. Interests? My #poogle Moana, #cycling (#Vanmoof + #Bianchi #CycloCross), gym, driving (#Mercedes #e350de), sometimes photography (#Olympus EM1 fan), #shoegazer, #britpop, eating out a lot, travel.
Goals: do the Tokyo SSM partnership, live on #Miyakojima in 5 years, speak much more Japanese, work for myself, #SUP more, maybe guitar again??? Used to pay a Fender Jaguar.

Öha, jetzt macht #VanMoof die Qualitätsoffensive. Hoffen wir, dass es was bringt unter neuem Inhaber https://www.vanmoof.com/de-DE/testing-lab?utm_source=newsletter&utm_medium=email&utm_campaign=240321_testinglabriders_de

#vanMoof Es soll Reparaturanleitungen für ältere Räder geben https://ebike-news.de/neue-chance-fuer-vanmoof-besitzer-so-will-der-neue-eigentuemer-alte-e-bikes-retten/217287/

#VanMoof Update https://t3n.de/news/vanmooof-meldet-sich-zurueck-software-updates-partner-staedte-1607296/

Ok, Knie gestoßen, 2 Tage Kreislauf (wenig), Autoreifen hie, #Vanmoof Ladegerät will nicht laden, Hinterradventil vom Brompton hält keine Luft mehr.
Meeeeeeh
