Do you want a pyEC?

I’ve finished making v1.2 of the pyEC and it’s ready for initial production. You can download the PCB files and make your own, or I can make a small initial batch for people to use and try. In the meantime I have some bare PCBs available for all layers.

I’d also like to hear about what you’d like to see for new layers. Maybe a Bluetooth layer & phone app? Leave your name and email in the comments and I’ll keep you updated about an initial production run!

    I want to recreate what you have done. On my e bike.

      I will continue to post all the design files for you to follow. I hope to soon have a batch of pyECs that can be purchased

    Hi, super nice project you have here!!!
    At the moment developping my cyclocar (.com or on facebook) and such a controller looks appealing for a vehicle control system. At the moment developping it as legally a bicycle..
    This looks like a good way to control a vehicle.
    An other way would be via a phone app and cable. At the moment its ‘analog’ with standard 250w controller. But it works.
    Interesting!

      I’d like to add Bluetooth to my pyEC and then create a phone App to act as the display. I would control it the same way you control a Nextion display. I have 2 reasons for this, first I like using my phone for GPS navigation and seems redundant to have multiple displays. I already have rear camera and bike display. The second is that many people already have an old phone they could use for this purpose, saving the need to by a Nextion

    Hey dude just started designing my 3KW mid drive and are trying to work out how to do the data logging and extra functionality that my controller lacks.
    I think a Bluetooth layer is a must, this was a phone can be used as a display for the bike.
    So how can I get one? How much does it cost? I have soldering experience so im not afraid of constructing it my self at all. Please get in contact with me i would love to be a part of this product! Thanks!

      Yeah I would like Bluetooth too, but the issue is the time needed to write the phone app. Make the hardware isn’t a bit problem. There are 2 ways to go about it that I see. First is switch the control layer to an ESP chip with Bluetooth built in or alternately just make a Bluetooth layer that takes one serial port. As I said, the hardware is the easy part, writing a slick phone app is more trouble than designing a PCB. I should expand by saying I don’t have any experience writing phone apps, so for me it’s a daunting task. Now if someone wanted to write the app, I’d happily make the hardware.

    I’d be very interested in one or more. And for ebike development as well.

      I’ll keep you posted as I get samples ready. Thanks for your interest!

    I’m going to be running two parallel ebike test platforms for geometry and suspension development and was just researching how to go about building a custom DAQ when your project was posted to hackaday

    You might want to go look at what is currently happening in the pedal power downhill bike market. Suddenly it “popular” for weekend warriors to have a DAQ like the pros. But they are very pricey.

    Thank you
