I need a realization of a wireless video transmission to an IOS or android device from a custom pcb via wifi. The task includes: - software implementation of an app, which displays the transmitted video on the device - pcb which includes a wifi chip and a camera interface for hdmi video signals. - firmware for the mentioned pcb Range will only have to be around 20m. Its also ok if a PCB designer only designs the pcb and the firmware.

I'm looking for an engineer to help me with an experiment I'm conducting as a hobbyist. I need a simple radio device built, that can transmit at a certain frequency with minimal power output. The truncated scientific journal article, containing the specifications and desired outcome is copied below. More information can be supplied as well. Thanks: Frey, Allan H., Human Auditory system response to modulated electromagnetic energy. Journal of Applied Physiology. 17(4): 689-692. 1962. (*) Asterisks indicate unreadable characters in the original copy. NOTE: In 1962, frequencies were expressed as kiloCYCLES, megaCYCLES, etc., with abbreviations being kc, mc The intent of this paper is to bring a new phenomena to the attention of physiologists. Using extremely low average power densities of electromagnetic energy, the perception of sounds was induced in normal and deaf humans. The effect was induced several hundred feet from the antenna the instant the transmitter was turned on, and is a function of carrier frequency and modulation. Attempts were made to match the sounds induced by electromagnetic energy and acoustic energy. The closest match occurred when the acoustic amplifier was driven by the rf transmitter's modulator. Peak power density is a critical factor and, with acoustic noise of approximately 80 db, a peak power density of approximately 275 mw / rf is needed to induce the perception at carrier frequencies 125 mc and 1,310 mc. The average power density can be at rf as low as 400 _u_w/cm2. The evidence for the various positive sites of the electromagnetic energy sensor are discussed and locations peripheral to the cochlea are ruled out. TABLE 1.

I am in need of a custom PCB for a wireless speaker. There will be 4 speakers and it must have Bluetooth as well as auxiliary capability. I would like for you to create a schematic so that I can have a few boards manufactured. If you can create a prototype and a schematic, I would be willing to pay extra. I ask that you have experience in creating PCB's and have custom boards before. I would like a good quality board, so I am willing to pay for quality. Please provide details of past experience in creating PCB's.

We have designed and fabricated the IDU with the intent of generating a TTL (Square wave) compatible clock signal with 3-ns of rise time, and 10- 40 MHz of pulse repetition frequency (PRF) and 20Vp-p output voltage. Unfortunately due to some unidentified flaws schematic we are unable to generate the required output. We are looking for someone to help us with the debugging and building of Impulse Drive Unit (IDU). Given below are the complete details of the project, should you this interest you. • Figure out the design error in the current schematic and fix the problem. • Schematic capture, Simulation and PCB layout should be performed in Altium • Board should be fabricated and the results should be verified. • Written report with design explanation, simulation and experimental results. • Signing the NDA ( Non-Disclosure Agreement) The copy of the schematic & BOM will be made available upon request. We request you to reply back if you are really interested in this project. Thanks.

I am searching for an electrical engineer that can take my idea and bring it to life. This project involves US standard electrical outlet knowledge, and the ability to integrate USB currents and small motors. The first step will be creating the product. You will understand the idea, and find the best way to achieve it. The second step will be creating a working prototype. You will submit a video of the product working. The last step will be designing it. This will be taking the idea and coming up with a consumer friendly design that looks good and is still functional. I will provide a description of the product and some really bad sketches to all that apply. You can look at it and send your quote to bring it to life.

We are a guitar pedal company based in Indiana in need of a circuit designer to work with us in developing new circuitry and troubleshooting / modding previous releases. Ideally, we will hire one person that will stay with us as the company grows. PCB design and layout experience is great, but not a must.
