Need a small modular mp3 player which can playback mp3 files from a USB flash drive and an SD card. It should have a one or 2 line LED / LCD or OLED display for track title (ID3 Tag), time remaining, and volume. The inputs required are SD card and USB 2.0 Outputs required are audio 1v, ptp standard audio output Controls required are: volume up, down and track forward and reverse Power requirements: 5VDC or 12VDC PCB format only, no enclosure required. simple push button (press to make) required for volume up/down and track forward/reverse. Should playback files once a valid media via USB drive or SD card is detected. PCB can be manufactured and populated by us. If you already have a module which can be modified to above requirements, it would be acceptable. The time frame for the entire project is 2 weeks from award of contract. Please apply only if you have the experience and expertise to deliver in time.

I am working on a small electronic device involving a PIC32MX250F128B microcontroller. The device will need to receive and send small amounts of data from a Windows PC via USB. I'm thinking the communication would happen through a virtual serial port, but am open to other suggestions. To save myself time, I'd like to outsource the coding of this part of the project to someone with more experience. I'm happy to provide any other details you need, and will provide a populated circuitboard for development/testing. The job would be finished once I verify the communication works and the circuitboard is returned. Ideally, the freelancer will have experience with USB communication using the PIC32MX family of microcontrollers. Thanks!

Hi, I'm looking for someone who can make a step-by-step, super simple explained tutorial on how I can build a drone based on Arduino. I need to know - All the parts that I need, including ebay links to order them (Find cheapest parts) - Step-by-step tutorial in simple language, on how I can assemble. Pictures/videos would be best if possible. - I need to have the code I need to run on Arduino for it to make it work - And overall I'm looking to build a small Quadcopter without camera or anything. This job is for those who have already built quadcopters/drones and can teach me how to build an arduino based on that is super simple to assemble and has cheap parts. I'm looking to spend maximum $100 on parts. I don't want to to google a tutorial and send me a link, but make it super clear on what to do so that with the instructions even a child should be able to follow the instructions. Type of drones I like (Simple and cheap ones:   [obscured]  /id/the-pencil-drone/ ) Som...

I'm looking to replicate a product. All (accept the INA 103) are essentially the same product found here:   [obscured]  /13-esd-calibration-test-targets Scroll to page 65 (page 34) of the IEC 61000-4-2 doc at the very end of the PDF for specifications and details for the product. We would like a sample before committing to a larger quantity, would be interested in pricing for 5, 10, 20 and anything close where a price break would occur. Let me know if you have any questions. I can provide a sample calibration certificate with data and curves as well. Would prefer if you can deliver the complete assembly including RF cable and attenuator but if you would like to focus on the current sensing transducer that is OK with me.

Hi, I need a high voltage circuit designed. I need to be able to transform a low voltage (ideally between 12-24V) to a very high voltage of 45,000V, so there is a potential difference between two electrodes of 45,000V (i can then vary the electrode size, distance to create the desired electric field strength etc). The output voltage needs to be variable to a minimum of the low input voltage and to a maximum of 45,000V.

I have a wireless flash trigger transmitter and a receiver. They work with a Amiccom A7105 chip. I want to develop something similar with an Atmel microcontroller and this Amiccom chip. I'm a electronic engineer and I need support for this project. I DO NOT need someone who writes all the code or design all the schematic, I NEED someone who can explain me some points : 1) I need to know how my trigger transmitter and receiver works(probably we need read the signals transmitted and received) (1-2 hours) 2) If they work with RF I need a quickly introduction on RF and protocol as ZigBee (1hours) 3) I need support to develop the library(SPI) to comunicate between microcontroller and A7105. (around 10 hours or less) I prefer working face to face so I prefer someone from UK / Italy or Europe.
