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.

Hello, I want a script to use for my Raspberry pi, for voice morphing. The requests are: - Apply effects in real time to an audio input (external microphone - external sound card); - the effects can be customize in the script. - if there is a way to change the effects by a 3x4 keyboard. - I need to be a stand alone solution, plug and play. (after customization); I need it right away. Thank you

To Design and Produce a prototype as per my specifications : Combined Battery Pack (50,000 MAH) that can charge a laptop - & Hard Drive 256 gb SSD & and another option with 3 TB Harddrive Also a basic SD & Sim Card Reader should be built in to the device Should be able to charge common, Samsung, Lenovo, Microsoft & apple laptop with USB 3.0 Output also should fast charge mobile phones with other USB output Also the piece should have a meter showing exact percentage of battery left & also how much of the hard drive is used. Essentially its a repackaging and design of products that exist already. i will provide the harddrive & battery sizes & other design elements needed to design and test the product to build a sleek working prototype. Product prototype must be ready by 12 April 2016

Design a circuit to collect (harvest or couple) AC power from the EMFs generated by overhead 3 phase AC electric transmission lines/circuits in order to power a remote, autonomous, 30 W field computer and sensor system. Such systems are located at the periphery of high-voltage transmission line ROWs (Rights Of Way). Minimum distance to the overhead phase conductors is ~ 20 meters. Power harvesting/coupling mechanism and design can be based on AC Magnetics (induction) or AC Electrostatics; I have significant experience in sensing and in obtaining power using AC Magnetic Induction, and would prefer an AC Electrostatic Approach. A DC Output is desired, but low-voltage (<220 Vac) could be used. High-voltage overhead transmission lines/circuits range from 69 - 765 kV and, typically, carry 100 - 1000 A. Initial work should target 500 kV with a 500 A load.
