Man has it been too long!

At the end of last year I picked up one of the M5Stack core units and have been busy working on learning how to use it. Part of the learning has resulted in a pdf that constantly get updated with hardware and examples of UIFlow code. I must have made a positive view on the staff of M5Stack when helping out on the forum as I am now the community manager their while also helping out testing UIFlow.

While I keep missing out on a lot of preorders and special offers, they recently held a competition and my entry was chosen as the winner. I will post more on this when the prize turns up but for now I will just post an update on things.

Project Sakura has been at a standstill due to lack of funding and part sourcing (mostly down to the motor being a single phase brushed DC instead of the 3 phase brushless found on most modern ebikes.

I finally managed to open the hub and remove to motor and discovered something, the reason the bike keeps blowing up the drivers is because the driver is underrated for the motor. The bike is supposed to be a 250W motor but after a quick test with a multimeter (and a rough bit of ohms law) it turns out that in normal use it has a 14A current use with a power rating closer to 500W!

I need to get a new speed controller for the bike now and may go for something closer to 1000W (just for paranoia sakes) but I will be adding some new sensors and a new central “Dash Board” based on the M5Stack to control it all.

Please come back and check on updates and don’t forget you can find me on youtube, Facebook, twitter and instagram.

I hope to post an update soon so goodbye for now.
