Hey what up guys been looking at getting a raspberry pi 3 for use in my armor build (http://www.405th.com/showthread.php?t=47681). I want to be able to controller the leds and such from my wrist but i have no idea where to start. Any ideas? Or is this kind of silly to try for? Of course this is just an idea as of right now since the armor isnt finished but hey I can dream right?
 
the Pi is good.
but keep in mind It Does not have a Batt controll system.
The cheaper Chip PC does.


The Pi is overkill . taka a gander at the parallax Propeller . it can do video quite well and its less PC more Micro controller.

Well I was planning on having a beefy power supply build into my armor anyway to power the lights and what not but ok ill check that out and see if thats any better than what i had planned. ill upload a sketch in a minute of what i want it to do.
 
Here is my beef with the pi. again . no way to have batt controll unless you wanna buy a Li charge chip an SPI or I2C wire it to the pi and make the OS see it as a batt guage

IMO if the dinky CHIP can do it for under 10 bucks and have WiFi And Bluetooth they the Pi has a long way to catch up at a 35 USD price point . .


what is awsome is that if you dont use it then its just not used No big deal . but If you wanna power a system off a Li 3.7V cell the board Like a real laptop can do charge managemet and thats VERY handy to have in a device.

What’s really great is that if you plug in to a charger and plug in a battery, the battery will charge - all the power management is on CHIP itself. Roughly, it takes about four to six hours to charge a 3000 mAh LiPo battery from a 5V 1A power source. Also, our delightful little Power Management IC, the AXP209, handles pass-through power, so while on and charging a battery, CHIP is basically running on a un-interruped power supply – If charge power fails, CHIP seamlessly switches onto battery power without shutting off.


Here is the power IC used. I am shocked that the pi's 3rd version does not have this. only fair exciuse is size .

You have to remember that if you do use a Pi its a whole new language its like linux on crack and heroin and acid all at the same time take some time to read all the info look at past builds look at led builds on youtube if it works its gonna be good but its setting it up let me how it goes I'm planning a watch dogs cosplay for play expo and i will be using a pi and a NXT for a prop
 
OH its not that hard.

We armor builders have to be persistent to get the stuff we make to look good and fit.
with that much will power Ill bet any one can learn to tweak linux for there needs.

Frankly https://www.sparkfun.com/products/11676 or https://www.sparkfun.com/products/11740along with a decent Micontroller is more then enough to do a LED controller interface .

One underdone route is to re use a android phone and just use a bluetooth RS 232 adapter and a hidden sub board.
Yes you have to code for android but you dont have to do as much wiring work and this lets you focus on the interface ..
