I want a driver to run 6 of these 24volt LED white light strips driven from a single power source. http://store.yujiintl.com/collections/high-cri-led-strips-ribbon/products/bc-series-dual-cct-ribbon-120led-2835?variant=3149575809 First see this video on driving a similar strip, https://youtu.be/jLia59KfkSw?t=1m32s Use voltage regulation NOT PWM, I need to use this light with slow motion and cannot have pulsing as happens with current lights I have. There should be 2 dials, one for brightness, one for color tone balance between the 2 color channels strips (warm and cool white) and 2 switches for turning on/off each side. 1 power cord. 2 cords to connect the lights.

Project; making a device to help people sleep. Design basis; starting with tempurpedic sleep mask design, want something made from the visco/memory foam, that fits and feels like tempurpedic sleep mask - but looks like an apple product :) I will be building in electronics including an LED into each eyepiece which will need to be behind a diffuser to make sure the LED illuminates the entire diffuser if possible. I need drawings that show how this could look, and I will work out, including the diffusers in front of each eye.

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.

I need someone to program an Arduino touch sensor pad. The main electronic components will be an Arduino MCU, touch sensors and LED lights. I have a few options on how I can make it, but I have a limited background in electronics so I need help first to determine which method would be the most effective, especially which type of sensors would work best for the field conditions. Once we decide on the physical layout, I need you to program the Arduino to pick up the sensor signals to light up the LEDs.

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...

Im looking for someone to help build a small amplifier to go in a product that I build. Specs are as follow. - 15w x 2 RMS minimum - Bluetooth (with the ability to have custom pairing sound) - The ability to switch from stereo to mono and only power 1 speaker instead of two - Volume control connected to board by ribbon cable - 3.5mm audio input connected to board by ribbon cable - LED power (+-) on board screw down - Speaker left / right (+-) on board screw down - 12 V power (+-) on board screw down It would be a cool feature to be able to add or remove bluetooth capabilities to or from the board when needed.
