Introducing: TeensySaber V3
« on: September 10, 2017, 11:13:29 AM »


The TeensySaber V3 is a minor improvement upon the V2 design. The only differences are:

1. The amplifier has been upgraded with a 3W digital amplifier which provides loud cd-quality audio
2. It is slightly shorter (2.5mm)

Perhaps more exciting than the actual hardware upgrades is the interactive board configurator which let's you select how you want to hook up your TeensySaber, then displays the circuit diagram and configuration file.

Configurator and V3 information: Teensy Saber Electronics V3
TeensySaber Softare and feature list: Teensy Saber OS (beta)

I should have TeensySaber V3 boards for sale in a few days.

I believe V3 also moved BladePowerPin1 to pin 6 and BladePowerPin2 to pin 10, according to the V3_config.h file on GitHub and my own experiments with the V3 board. Please update the schematic.

BTW, a few friends and I are building some sabers based on your design. Thank you for making your excellent work available.

Isn't that what the schematics say? What schematics are you looking at?
Glad you find the designs useful, that is what open-source is all about after all. :)

I believe the schematic image here is wrong - Teensy Saber Electronics V3.0
Shouldn't Q1 be connected to pin 6 and Q2 to pin 10? I just downloaded the KiCAD files from that page and the KiCAD schematic also looks wrong.

I'm confused, not only does it look right to me, it looks exactly like what you describe.

Q1 is connected to CH1 which is connected to pin 6 on the teensy.
Q2 is connected to CH2 which is connected to pin 10 on the teensy.

Ah, I see my mistake. In previous schematics the lines for Q1 and Q2 went horizontally left right into the Teensy pins. But for V3 you created the CH1 and CH2 labels as a way to jump over to the other side of the Teensy instead of drawing lines. I was biased from the V2 schematic and didn't notice the CH1 and CH2 labels had been inserted so I just saw those lines connecting straight across left as in previous schematics. A bit confusing, but the V3 schematic is correct. Sorry, my error.

Our sabers are progressing. We're driving a test section of 10 RGB LEDs to dial in the blade diffusion. Tomorrow we'll be hooking up the speaker and some switches to test: sound, on/off/modes, and motion. We're gunning to have our sabers complete in time for the movie opening.
