Looking for an experienced electrician/technician that is familiar to work on a great growing team. This job and many like it would consist of performing data collection and maintenance on electrical equipment while energized. Our company has the potential to grow on the west coast at a fast rate but finding skilled team members, willing to work long hours and travel nationwide seems to be the hardest part. We have the opportunity not only to use someone on this job but many like it.

Looking for someone who both understand eeg capabilities with thought reading/movement and has practical engineering training (example: emotiv.com). Needing an actual eeg machine built and/or directions to build one that can connect to and control external hardware/software through thought-commands (ie., up, open, down). Please DO NOT APPLY if you do not have direct eeg software experience and already know how to do above and be able to prove it before hiring.

Seeking an Engineer to prototype a battery-powered, Arduino-based Bluetooth Keyboard Foot Pedal that pairs to a computer or mobile device and sends the letter [J] when pressed. The user has to press [J] when his hands are full, so a footswitch would make life easier. User would switch on the pedal, pair it with his laptop or phone, then press the pedal each time he wants to send a [J]. Project largely involves following this tutorial, but enclosing the Bluefruit from view: https://learn.adafruit.com/bluefruit-bluetooth-wireless-foot-pedal-switch Desired Milestones - Engineer completes non-disclosure and assumes no ownership over schematic or product - Engineer submits schematic / circuit diagram to Client along with simple description of function - Engineer submits list of parts (x2) needed to Client; Client orders/ships parts to Engineer - Engineer produces single prototype (for keeping); shares video of functioning pedal with Client - Engineer produces a second prototype (for sending to Client); ships to Client - Client confirms function of pedal Bonus Milestone If the Engineer can detect a long-press (hold for 1 second?) of the pedal and send the [Spacebar] key instead of the [J] key, this would allow the switch to perform two functions. Notes I am not the expert, but I assume something like this pedal https://chicagodist.com/products/foot-switch would connect to a box containing http://www.amazon.com/Bluefruit-EZ-Key-Bluetooth-Controller-Industries/dp/B018A2SV00 and a battery, with an on/off switch and a Bluetooth pairing button. The pedal would ideally butt-up against the circuit box to appear as one unit, but may also be separated by a few inches of the pedal cable. The circuitry should be enclosed (not visible to user).

I'm building a pulse oximeter for home / fun use but can't get it to work. Have a schematic that has some holes in it (resistor / diode / capacitor / LED values) that I need someone to figure out and show me how to get it to work with an Arduino. Basically consists of 2 band pass filters, LM358, etc. Also need that person to look at my Arduino code and fix it up so it works. Only seem to get one reading and then it doesn't refresh / take another reading. Currently it's just running off a breadboard which is fine, need someone to fix my schematic design and code so that I can replicate at home on a breadboard and get it to work. Really needs someone that has built something like this before (so you know how they work) and that can get my schematic and Arduino code to work. Also happy to take suggestions if you have a better way to build one of these that works. Can provide schematic later.

I need a report of 40 Pages to be written on the following content and structure. Structure: 1. Abstract 2. Introduction 3. Overview electrical drives 4. Brushed DC Drive (in-depth) 5. Pulse width modulation - PWM (in-depth) 6. PID (in-depth) 7. Encoder with Hall effect (in-death) General Information: Layout is not important, content is important. Font: Arial 10, normal side edge, 30+ pages What i do in the practical part you can see here: http://www.sainsmart.com/sainsmart-instabots-upright-rover-kit-pro-updated-2-wheel-self-balancing-robot-kit.html It is a two wheel self balancing robot. Hardware i use: Arduino Mega 2560, MPU6050, L298N, rest approximately like the link above. Would be good referring to practical part (if it fit to the context you writing). Also important need your sources you used (should be arround 10-20) Structure Infomation: to point: 1: 0.5-1 pages, referring to practical part and the topic 2: 0.5-1 pages, Background and motivation, Aim and outline of this thesis (can also used in 1.) 3: 5-7 pages, structure and types of drives, basic mathematical background 4: 5-7 pages, structure (more in-depth then 3.), equivalent circuit diagram, math (in-depth) 5: 3-4 pages, overview, somes charts, pro/cons (why PWM), referring to practical part 6: 5-7 pages, overview, P/I/D every part separate, pro/cons (why P/I/D consider separate), Ziegler–Nichols method, math (in-depth), referring to practical part 7: 5-7 pages, overview, structure, equivalent circuit diagram , math (in-depth), referring to practical part
