The task is simple, recreate the teensy 3.1 with the same number of pins and specs, just make it as thin as possible using thinner pcb, chips on the back, etc. Bidders must provide evidence that they have experience designing and producing electrical chips. We need someone that can take this project through to a working prototype. If after thorough testing we agree that it performs to our satisfaction, we will look to produce the chips in some quantity but what you should bid for is just for building us a prototype.

We are looking for a talented FPGA programmer to help us implement a low noise (<10nV/(rootHz)) lock-in amplifier for heterodyne detection of sideband signals. Carrier frequencies range from 0.3 to 1.5MHz. The lock-in amplifier must have the ability to generate signals at specified frequencies and demodulate signals at the sum or difference of two frequencies (FM/heterodyne detection). Your job will be to develop a working prototype that does the following: 1) Takes in signals via a high speed, 16bit ADC 2) Generates a sine wave with programmable amplitude (ranging from 0 to 5V) and frequency, f2 = (1 to 1000Hz) 3) Demodulates the signals at two frequencies f1+f2, f1+2f2. f1 is determined from the DAC input. f2 is the frequency generated in step #2. 4) Outputs the RMS amplitude of the two demodulated signals via a low noise, 16bit DAC. We have an ADC and FPGA eval board already chosen, part #'s AD9268 and HSC-ADC-EVALCZ from Analog. You will need to help us choose the DAC and fi...

** NOTE: WE WILL REQUIRE A NDA TO BE EXECUTED BEFORE JOB SPECIFIC ARE RELEASED ** Looking for an expert in programming hardware components. Ideally, you will integrate and program the following: Arduino (if you recommend something else, I will entertain idea) with the following components: - Bluetooth - Accelerometer - motion sensor - proximity sensor - magnetic switch - temperature sensor Once put together, this system will execute actions based on specific input from one or more sensors. Example, when accelerometer indicates specific motion, do this, or activate another sensor. Ideally, once a developer is chosen, I will provide list of component types that would be needed. The chosen developer will have the experience to find and select the most appropriate component from any of the dozens of online resources and recommend. I will then purchase and mail them to you, or will reimburse them to you. The final goal is for you to design, build, program a complete product based on my...

I am looking for a freelancer who can do a simple measurement of the Total Harmonic Distortion for a Schneider Conext SW 4024 Inverter. This may be done on the 120V or the 230V version. Measurement needs to be made with a nonlinear load, more details will be provided to selected freelancer. You need to have a distortion analyzer as well as an oscilloscope available to bid on this job, and of course have access to this inverter too - at a friend's or colleague's place for example.

My company is called: "OS.ALT" (Open Source Alternative) and we are looking for a fun, yet professional looking logo to represent our budding tech company! What I like: - I talk about coding and programming - I am very interested in vector and pixel look, done right - also curious about the circuit board look, binary (so long as it's subtle and tasteful) - Think geeky, but sleek about it! I'm very fond of the blue, purple and jewel green/aqua palette, but can be flexible. Here is an example:   [obscured]  /1aM620f I am a one-woman show so having a feminine touch is nice too. (not girly though) I have attached a sample request even have a mascot/character that I can provide upon request, a reference sample is attached for your reference :-) (this is an outdated website but you get a better feel for our personality:   [obscured]  / ) What's Needed: (2 total renders) - Main Design is using text "OS.ALT" - 1 Text logo with graphic alongside - 1 Text ...

Since I'm often overloaded with work, I am looking for a work buddy. Someone I can trust, and share future projects with. I am very specifically looking for someone living in Davao Region, Mindanao, Philippines. I need to travel several times per year to Tagum City for personal reasons. It would be great to get in contact with some engineers in this area, so we can work together on projects more efficiently. These are the skills I'm looking for: - Circuit Design. You know how to desing electronic circuits (analog and digital), and have preferably some experience with a design program like Eagle, Target3001, ... (or anything similar). - Embedded Software. You know how to program a microcontroller (preferably in C). I myself have experience with 16-bit PIC microcontrollers and will soon learn how to use the Cortex M7 (from ST Microelectronics). Experience with one of these would make our cooperation easier. - IoT (Internet Of Things). For future projects, I will need to focus on micr...

We need a printed circuit designed for a very compact phone charger. It needs to be as small as possible, and particularly as "flat" as possible. while still being designed to UL guidelines. The project consists of three separate PCB's . One for the high voltage circuit. One for the low voltage circuit and some of the watch components. Lastly, one for the watch LED matrix, battery, and any remaining watch circuitry. Dimensions for the board shapes and mounting information will be provided on award. 1. Prefer knowledgeable in eagle PCB 2. Must be knowledgeable in clearance and creepage for power supply/charger (this is very important) 4. Orientation of C1 in the charging circuit must be lying down (freelancer needs to re-draw its foot print) 5. Please review the existing component sizes versus the part list for checking purposes. 6. Final deliverables shall include standard gerber files 7. High and low voltage circuits require a minimum 5mm separation. This will need to ...
