So i am doing a lightsaber using the teensy 3.2 as a main board (https://trello.com/b/1MbM08rb/long-hilt-teensy-lightsaber-project) Already purchased the 3.2 and the audio adapter board. Jumping ahead of myself i already soldered them together (got some leads from the underside of the teensy, namely 29-32 , 25, 26 for the sda,scl, pwmx2, rx,tx just in case) Also i cut down the audio adapter. I am hoping i didn't screw something up :s The board was too wide and i wasn't planning on using the ac97, headphone jack, or trim pot area. The cut is just outside the two visible resistors one above and one below the main pin lines, leaves the board just slightly wider on both sides than the teensy. Also picked up 6dof imu-6050 board, a class d 2.5 watt amp, 8ohms 2w speaker, 3 mom switches 2 with led rings (1 for power/aux, 2 for aux/menu/effects). Plans are to buy a LED engin rgbw 10w star, 2 accent rgb 20ma led's, and i am looking at making a 4ch 1A led driver similar to http://www.instructables.com/id/Easy-CAT4101-LED-Driver/?ALLSTEPS minus the extra frills. Not sure power wise though if i can get away with two panasonic 18650's w/3400ma @7.4v thats the plan but being a major noob that's not based on any calculations but off of what i have seen others use on forums. I might get away with 4 cells but i'd have to change the hilt some if i could do it. Led's forward voltage is 2.2v-3.4v @700ma max's out just above 4v depending on the die. Will be using a recharge port as well.
My plans are to include as many of the feature found in the major popular lightsaber sound and driver boards like the Crystal Focus http://www.plecterlabs.com/catalog/product_info.php?products_id=1173
As many of these features as possible:
3 or 4 channel color mixing (7 to 10 programmable presets using a windows gui)
Multiple sound banks for either programmed presets tied to the colors above or cyclable or both)
Flash on clash i.e. pulse of bright light (color select-able) on detected impacts
Fade on/off light for on/off effects combined with sound effects
Blade shimmering effect
Random low level blade pulsing
Constant hum with frequency changes (based on swing speeds or gestures?)
2 Accent rgb's that change to the color of the blade and pulse on off when main power is down.
Stretch ideas would be demo or special modes where the blade would play music accompanying a preset theme and/or a easter egg mode with color shifting and music (possibly with the accent led's pulsing to the music?)
As i stated above i am a noob. While i have built every pc i ever owned, i only just stated learning the basics of electronics and schematics and my programming experience isn't much more than a week of html from college. I have been reading and studying as I plan. Reading cross referencing etc. I could really use some advice. Right now i am trying to straighten out the wiring because i am on a spend as little as i can so my wife doesn't kill me budget i am looking at purchasing the bulk of the remaining electronics Namely the led star, accent led's, led driver components, and anything else that come along with that..which is much of the issue as i am unsure of what i need resistor, power regulator(s), caps etc.. The teensy is gonna run off of 5v, led drivers x4 run off of 3-6v on the Vin and upwards of 25v on the Vcc (i don't really understand the difference between voltage in and voltage source), the Amp says it runs 1.5watts for a 8ohm spk but also said its up to 5.5Vin, The 2 swtich led's and two accent rgb led's i figured i would run directly off of the teensy. I don't mind if the 2 accent led's run off of the same pwm i/o's sharing the power since i don't think i can come up with another set of 3 pwm's with the sound adapter hooked in. Do i run the boards all off of a 5v linear regulator? or does each piece need it's own, Any help on how to know if i need to use a cap and calculating resistor needs i might have.
Re the audio board i only plan on using a mono speaker and i was hoping on using the i2s sound connections but in the library it shows them coming off of the ac97 area do i just use pins 23 (LRclk) and 22 (tx) or am i screwed or are there special circumstances i need to have in mind. I was hoping to either play up to 2 files same time option if i needed to or if there was a way to run 2 channels of audio over the mono (not sure that's even possible)
Also i was hoping on using the pwm on pin 6 for one of my led's but it has the memcs hooked up to it. I don't plan on using flash memory is it locked into using the memcs or can i use it as i would if it wasn't connected memcs.
As you can see i have quite the road ahead of me. I am planning on having a usable prototype by the launch of starwars on dec 18th though i know i probably won't have a full featured one by then. Any and all help is super appreciated. After writing this out i know it's quite the load to throw out there.
Current state of my wiring diagram is here: https://trello.com/c/6Vbo2LRI/28-current-state-of-my-wiring-diagram
Photos of all components that i have to date are on the trello page and i am gonna start linking the data sheets to all parts as well.
Thanks
