But here is the needed experience Experience Needed -Mechanical engineer -Consumer electronics -Electrical engineer -Product Development -Firmware Skills I'm the founder of Glo-Ryderz , our company goal is to make consumers ride with style with our newest innovative smart balance board and wheel's. ... Therefore our goal is to put the motor else where and redo the design but, we want it to function as a normal smart balance board by allowing this it lets our customer be able interchange wheels easily. in less than 30 seconds Requirements Needed For Prototype Product in Return For Exchange of Payment What we need in return is the schematics of the electronic design, part selection, pcb design, programming firmware compatible with iPhone and android, chassis design, wheel design, building of the actual prototype must look like the finished product, testing adjustment calibration, Rapid Prototyping The Prototype must go through vigorous testing to ensure safety of the end user.

- A Full Electrical layout(complete with PCB- preferably with DesignSpark) for a Current and Voltage Monitor - Current Monitor up to 450 Amps - Voltage Monitor up to 1000 V - The data will then be fed into AD Converter(the choice is on the freelancer) So the first Task before we begin: The Freelancer must propose a Anti Aliasing Filter Design for 10 kSample AD Converter with frequency input(desired) ranging from 2 kHz to 5 kHz. If the freelancer can propose a very good and reliable AA Filter, he/she can directly take the job forward. -Expected duration : 5-6 Days for AA Filter and 3 Months for the full layout

I am building a robotic arm that needs to be able to record and repeat movement. A similar example of what i am building is found here: https://www.youtube.com/watch?v=QVsdaPGUn1o Instead of using an arduino i would like to use a raspberry pi, and instead of using servo motors i would like to use stepper motors with encoders attached to them that are found here: http://www.phidgets.com/products.php?category=23&product_id=3334_0 http://www.phidgets.com/products.php?product_id=3531 I would like to be able to connect to the robot over the internet. I would like the program to be written to accommodate 6 motors with their individual rotary encoders. I would also like to be able to add sensors to the arm such as pressure, distance, temperature, voltage/amp, camera, etc. I would also like any suggestions as to what other hardware would be needed to make the robotic arm work effectively, with accurate posistioning, and to integrate the needed sensors and wifi.

We are looking to have a custom PCB designed with the following design parameters. 1. It needs to be designed to fit in a din rail enclosure (similar to the ones from Hitaltech) 2. It will be powered by DC power (12-24 volts) 3. It will be used in an industrial environment. 4. It will accept digital pulses and need to count them accurately over time. These pulses are cyclical in nature meaning the pulses occur and then stop in a repeatable fashion AND when they are 'pulsing', the pulses occur in a sine wave fashion. Example. if you count pulses every 10 ms for 100 ms, the ten pulse counts may look like this.... Count 1: 10 Count 2: 14 Count 3: 20 Count 4: 25 Count 5: 31 Count 6: 24 Count 7: 20 Count 8: 15 Count 9: 10 Count 10: 5 Counts 11-20: zeros Note: This is for example only. Actual pulses may not replicate this pattern, and the timing of taking pulses may differ as well. 5. The pulses will then need to be smoothed and converted to an 'actual number' based on a known value. Example: If the smoothed pulses over the last 60 seconds was 22 pulses per second, it would divide that number by 4.1666667 to obtain the result. 6. The range of pulses is 0 to 750 pulses per second. 7. The length of time to adequately smooth the signal can be from 30 to 120 seconds. It would be preferable if this could be adjusted (either through firmware, or jumpers/dipswitches, etc) 8. Once the pulses stop for longer than a predetermined time (say 5 seconds or so.... also possibly user defined), the logic needs to 'zero' the smoothing. 9. Based on the "actual number" the board needs to output one of three signals. 9.a Digital pulses. The number of pulses output per second will be equal to the "actual number" * 1.38888889 9.b Analog output. 0-10Vdc and 4-20ma. 0v and 4ma will be at 0. 10V and 20ma will be adjustable (firmware and/or jumpers/dipswitches, etc) 9.c OPTIONAL. a simple LCD display. 1 x8 etc. that would show the actual number. We would like a prototype developed to prove concept. Arduino etc. is OK. We need a first article board designed to test. We need all drawings suitable for board production by any reputable PCB production facility. Final design must be DFM and ready to effectively produced at high quality at minimal cost. We need a complete BOM (bill of materials) and if possible, a likely cost estimate of the board. Components selected must be: Readily available and commonly used, cost effective, of suitable quality for this application. Firmware developed in an industry standard fashion, efficient design, and completely documented. Contractor will need to sign an NDA and a Work Made for Hire agreement to insure confidentiality and complete transfer of ownership of all designs of hardware, software, firmware, and algorithms. Once an NDA is signed, further data as well as a rough spec sheet will be provided.
