I've been working for a few months off and on to make a bluetooth enabled lightsaber. I've had some success, but I'm looking to make some changes that I hope will make it a little better. Right now, I'm using the NRF52 Bluefruit along with a Music Maker Feather Wing (https://www.adafruit.com/product/3436). My main issues there are that I have to use an SD card (which has an annoying tendency to pop out during installation in the hilt), and I'm not a huge fan of the audio library (I keep running into random issues where trying to start playback of a new file causes the device to either lock up or reboot). It also is a bit bulky because I need a separate breakout board for gyro/accelerometer/magentometer (https://www.adafruit.com/product/3463).
In doing more research, I found the props shield, which looks like it has just about everything I need (on board memory that is sufficient for my uses, along with the same motion sensors I'm currently using and ready to connect DotStar LEDs, which I'd like to move to for my emitter). However, the issue with going to Teensy is the lack of a good BLE option (as far as I can see). I'd need a separate shield for the BLE support (and I'm trying to move away from having another board). I'm considering the following, but I'm not sure if it is reasonable:
NRF52 Bluefruit - https://www.adafruit.com/product/3406
Teensy 3.x Feather Adapter - https://www.adafruit.com/product/3200
Teensy Props Shield - https://www.adafruit.com/product/3085
2 x 144/m DotStar LED Strip - https://www.adafruit.com/product/2241
3.7v/10A LiPo battery - http://www.thecustomsabershop.com/P...PCB-Protected-Rechargeable-Battery-P1282.aspx
My main questions are:
1) Can the feather adapter be used to interface the props shield with the feather? It looks like it is designed to use feather wings with a Teensy. I'm relatively new to this, so I don't know if there is a reason it couldn't be used the other way.
2) Does it look like the battery will be sufficient for running 2x 144/m DotStar LED strips? The 144/m is important to get an appropriate resolution for scrolling and a relatively solid color throughout the blade (at least based on what I've been reading from others who have done similar things with NeoPixels).
Any thoughts/comments on the proposed components, or gotchas you can see, would be greatly appreciated! Thanks!
