My reading vision is not what it once was. Can you tell us how to compute the meaning of 20x4, for example, in order to understand that as an actual measurement size?
Best place to get the upgraded screens for the USA?
ebay is as good as anything. Just search for HD44780.
20x4 refers to the number of characters wide and high. so 20x4 is 20 characters wide, 4 high.http://www.ebay.com.au/sch/i.html?_from ... Categories
But if you need a big screen, just go for the Cycle Analyst. The main reason I developed my brain box was I wanted a small inconspicuous screen, and the CA didn't have some features I needed. But now the new v3 CA has nearly all the features of the brain box, and is a product with a lot more history, production volume etc, so you are likely to have a more robust product.
So there is not much point me making a big screen brain box. This means I will focus on small-screen and no screen throttle interfaces.

- analog throttle input/output to suit hall/pot throttles, and normal ebike controllers.
or ETA for this option?
Soon. I have just had to set up a company to take care of this project, so that has taken a bit of my time recently, as well as keeping up with orders. Once I ship out the last few outstanding orders, I will stop the current release manaufacturing, and focus on the R&D of the next variant.
High on the list is:
- analog throttle
- basic model BB without display, with PC-USB programming, possibly with common firmware with the display varient. So I don't have to maintain two varients.
- electronic torque limit, for controlling maximum torque (mainly at low speeds), while still allow higher power at higher speeds.
ETA: Let's say a month or so.
- AU$140 + shipping
- unfortunately these are quite time consuming to assemble, but it is still cheaper that a CA and Analogger.
- If you are not interested in the datalogging or temperature sensor, I can probably drop the price down a bit, let me know.
I think these come w/o the datalogging & temp sensor now at $140 or ?, correct?
Are these still available now? Cost for datalogging & temp sensor is?
What options will be sacrificed to add these two options?
No datalogging for now. It is a cool feature that I used a lot during developement, but most people really don't need it.
Temp sensor is simple and may make a reappearance, but again once setup you never end up using it apart from the nerdy I must know more stats aspect. Those seeking to really push the limits in terms of power just shouldn't be using friction drives, and the brain box is really design for my friction drive first.
Price is $140. No datalogging, no temp sensor. I really should update the first post.
But there will only be a few more sold, before I shut shop for a while. This will let me get feedback from all the Alpha testers, and fix everything up for the next version.
