Design three types of universal LED bulb driver: 1.) Using minimal component to keep cost down (See "01.jpg" and "02.jpg" attachment ) 2.) Using integrated circuits for higher brighter/Life of LEDs(But cost must be low) 3.) Using some high end technology to keep Quality and life longer(You can also add extra features like light sensing technology and make it energy efficient) Input: 90-260v AC Output: Volts: Universal Amps: Configurable just by replacing transistors or any single component(No need to change design) Note: I do not want any current leakage/wastage (or as minimal as possible)

i am looking of some onto convert some arduino code to c++ with chinos/rt based OS from arduino code, i also need you to do the opposite. adruino uses atmega chip the chinos/rt uses stm32f100 and the last thing is i need to do help add support for a device to one of the codes. the hardware is a wii nunchuck replacement pcbs made specifically for controlling an electric speed controller.it has been made because current wireless wii nunchucks are unstable and have bad wireless connectivity. the wiiceiver is a pcbs that was deigned to plug in a wireless nunchuck receiver in and output pwm signal for and electric speed controller and servo. i need to make the wiiceiver read the axis and button presses from my nunchuck pcb. but i want my nunchuck pcbs to stay comparable with arduino so i was going to allow support for stm32f103 and them release arduino code to the public. ardunio code: https://github.com/jaustindavid/wiiceiver chibios/rt code: https://github.com/vedderb/nunchuk_mod

I am looking for someone who can build our second prototype. We need a screen that can be easily visible in direct sunlight, bluetooth technology to talk to our mobile app for screen to display things, and a magnetic backing for the device to magnetically attach to something. All needs to be weather-proof because this device is meant for outside use, so perhaps a protective casing around device that will not inhibit the visibility of what will be displayed on the screen.

Using a Rasberry Pi 2, monitor a analog input and using software compute commands needed to adjust a speed to maintain a set value. For example, if the set speed is 100, then we need to see if the actual value from the analog input is greater or less than this, apply a delay to adjust the response to match the real world response time. This value is then inserted into a RS485 ( Modbus) string and sent to a speed controller. This is a continuous process and is very slow response (5 seconds).
