It’s been a while since I did any work on this project, but I pulled out the components the other day and started to look into the Bluetooth connection between the Raspberry Pi and the Feather 32u4 Bluefruit LE board. It turns out to be complex and on the whole not very well explained how to make these devices talk to each other. In the final analysis it’s not actually that hard – but you have to do a…
If you are thinking of buying Adafruit components like the ones I regularly use in my projects and you don’t want to pay for, or wait for shipping from the US then you are in luck! I recently discovered that you can order Adafruit components from Core Electronics in Australia. They claim to stock the entire range of Adafruit components. You can find them here: https://core-electronics.com.au/
I may still be waiting for my 3D printer to arrive, but in the mean time, the components for my HUD were waiting in the mail box today! It included a Rasberry Pi model 3 B, an Adafruit Feather Bluefruit (bluetooth enabled Feather development board) and some headers for the Bluefruit. So now I’m ready to push forward with this project and get the electronics finalised. Once the 3D printer arrives, then I can start working on housings for…
Ok, today has been an interesting day for discoveries. I was thinking about the limitations of having to have a wired connection between the helmet and main unit on the bike and it got me thinking about Bluetooth and wireless options. The first thing I discovered (which I wasn’t aware of) is that basic Bluetooth modules (and slave and master pair) can be readily inserted in place of a serial connection between devices. Unfortunately I don’t think that this…
