SOLUTION TO BLUETOOTH ISSUE

A problem was encountered with the built-in Bluetooth. Metal enclosures can cause the signal to drop and the connection to be lost. For now, the solution to this problem is to use an external Bluetooth module like one would with most VESC controllers. In future updates we will add a Bluetooth module with a more powerful output and a connector for an optional external antenna to the design. Both solutions, present and future, will solve the Bluetooth issue.

COMMENTS:

Thank you all in this community who have supported my efforts thus so far! I have a small stock of the controllers ready for purchase. This small but manageable stock allows for a gradual approach of me learning business and manufacturing. Product design, manufacturing, quality checks, and logistical handling has been some of the toughest things for to me to learn over the past few years. I appreciate your patience thus far and I don’t intend to stop. I aim to only ever improve every aspect of my product as time goes on. Your support will help me speed up my progression and even hopefully converting this passion in EV tech that I have into a full time career.

This thread will be dedicated to the Little FOCer for any updates, announcements, and discussion.

So…the website launched and was advertised simultaneously with other internet outlets. In the time it took for this thread to pass moderation, all the stock sold out.

I feel bad that this forum didn’t have a chance to buy and I do apologize for that. I’m gunna handle it a bit differently next time for the next round of units I prepare.

This is a little bit like buying stocks on NASDAQ. :crazy_face:

This is like buying a PS5 on launch day.

Those are special versions meant to be compatible with a popular single-wheeled balance-based contraption :wink:

They’re in the EU and stocked by the distributor. Not sure if he’s shipping those to the states. I’ll ask

Well…I just ordered one… I’d very much appreciate it if it found its way to me in the US. That’s really the project I’m working on, and it’s a very important one for me.
If it’s worth anything, my title will show that I’m kind of a big deal. :innocent: :pray:

Either way, fingers crossed. And I do appreciate your work on this project. Thank you for making these available at all, even if I have to wait.
