Project objetive is to package an LCD display module, 2 LED's, on/off switch, 2xAA batteries, battery terminals, and wiring into the constraints of an existing plastic prototype housing with removeable battery cover and make them fully operational for field testing. PCB design and IC programing for LCD module already completed. Also, looking for guidance on how to improve and industrialize for production. Freelancer must be located in Michigan in order to complete this project.

Background: As you likely already know, to control amount of power a flash puts out, flash duration (and hence light output) is reduced by a thyistor control that quenches the full power flash early for light output less then 100%. Requirement: Need a circuit to be designed (along with PCB design) which will register the flash quench duration (generated by the center pin on a DSLR flash connector) and converts it into a power output that can drive a bank of high speed LEDs. Either using purely discrete components or using an arduino (your choice whatever you think is simplest). If a micro-controller is used, I will need the code as well. The output of the circuit should be able to drive and control intensity (either PWM or otherwise depending on the LED driver driver used) of a bank of LEDs.

We are looking for a resource to design a miniature PCB board 10mm x 10mm in size to produce a MEMS pressure sensor. This will be configurable for both gage and differential and need to be compensated and able to be calibrated to the following specifications: Switch Type: Normally Open • Type of Actuation: Vacuum (Contact closes upon application of vacuum pressure, Open upon release of vacuum) Pneumatic • Set point trip pressure: 0.25 +/-0.09 inches of water vacuum • Set point shall not be affected by application of 10.0 PSIG positive pressure Electrical • Contact Resistance: 500 milliohms maximum • Recommended switching load: 10-20 milli-amperes Physical • Operating Temperature: -15 to +55 degrees C • Terminals: Tinned (PC board mounting) • Media: Gaseous oxygen to 8.0 PSI positive pressure

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

link to kicad project. https://drive.google.com/file/d/0Bym9XrdeViekWDZTSjZTRG1iTmM/view?usp=sharing hello , i have a project for you. this is an electric speed controller. this design is finished but i want to do 2 things to it. i want you to study it and design a way to join 2 together. i want you to join the positive and negative power inputs into the 1 and have them closer to the bottom of the pcbs. i want you to consolidate the parts so they share any parts that can be shared such as the voltage regulators usb and if possible the mcu. the second thing that i want you but is actually the priority, is do is make a second pcb using this current single pcb design and reduce it as much as possible. the current speed controller is made for 60v and rated for 100A i want to make one that is small and only rated to 10A at maybe 24v. the motor control ic that is currently used is the TI DRV8302 i want to replace that chip with the DVR8332 that has lower power ratings but also has...
