    Delays, excuses and false promises are all that is provided by Betaenergy. No solution and no work. Betaenergy requested I release the milestone payment moments after accepting the job. DO NOT HIRE BETAENERGY. Just a ripoff merchant.Will not even admit that there is any problem. just keep asking for 3 more hours, yet days later still no results.Again, DO NOT HIRE!Very specific instructions were left for BETAENERGY, no questions, just always ask, 3 more hours.

    Design electronic circuit used in a IR fluorescent sensor that modulates a laser light source at around 20khz. Flourescent light is gathered through a optical system and focused into a 16 position photodiode array. There are 16 identical photodiode amplifier filter demodulation circuits that reduce light noise and ampllfy the 20khz analog signals from the photodiodes. The 16 analog voltage amplified filtered demodulated signals feed into a digital processor PIC 32 and an algorithm is used to determine when to output a logic signal to another device (0 Vdc). The VOLTAGE gain in each of then 16 photodiode circuits can exceed 2000X and can to be automatically adjusted by the microcontroller. The board has ethernet output, .9/ 2.5ghz Zigbee wireless transmitter, and a simple 2 line LCD interface with momentary pushbutton used to stroll through menu.

    Need someone to program a clock with 3 columns (similar to a digital clock : Hour ; Minute : Second) Instead of a number the columns would form 1 unified shape. Each column would take on 3 different colors: Red Green Blue. The color combinations would determine the time to the 1/4 hour. It&quot;s not meant to be an accurate clock, as in, to the minute. It is meant to give a general feel for the hour. More information on how the clock works will be provided with a reasonable bid. The steps I see beyond understanding how the clock tells time include the hardware to use, writing the code and then building (or directing a build) of the prototype. Hardware using Arduino would be easy as I could be directed in building the prototype if needed. I see the parts needed including: the board, RGB LED&quot;s, crystal (to keep accurate time), wiring, power 5V (just need prototype now), ***extra a light sensor or ping sensor for proximity (for varing power modes). Other hardware options exist but want to be able to purchase and build this myself if needed.

    I want to create a PCB breakout board to link a femtoduino (ultra small arduino) and a xbee device. Effectively the breakout board will have the 0.05inch pitch female pins for the femtoduino to sit on. On the outside of this will be the another set of female pins for the xbee (0.01inch pitch) to sit on. And then I need a few more arduino pins &quot;exposed&quot; on the edge of the board. I have some gerber diagrams of the femotduino and a breakout board for you to work from fro measurements. I also have some power requirements which I would like designed and built in which I will discuss with you once you have won the project1) You must be willing to work on this project over time as this project progresses, we are in prototype at the moment. If I am happy with the work, then we will move into an hourly payment arrangement.2) You are to provide me the eagle and gerber files (and whatever else is required for PCB printing)3) I will own all rights to the design once completed.

    I&quot;m looking for freelancers on a audio product that I am looking to develop for production for the consumer market. This product will be developed based on requirements and specs provided such as specifics parts, chips, and internals needed. I am simply a visionary and entrepreneur, I need the right time to make this happen. Depending on what is needed I may need more than one freelancer, one for the product board, another for software writing and etc. Input is greatly appreciated and will be considered during the hiring process. Due to this being a first time venture I am not sure what our budget will be but a max per hr limit will be set to avoid overages and to allow monitoring of the stages.Freelancer must be familiar with the following:-Designing pcb layouts based on the product specs:-Skilled in audio engineering and the pros and cons of certain layouts or engineering methods-Able to work with other members such as design and/or software coding-A NDA is required as this product is intended to be produced later on for consumer sale.Any questions you may have feel free to contact me at any time.

    I need a circuit that monitors a thermostat. The thermostat is a 24vac line. The input will go into the ADC of a digital IO pin of an arduino.The circuit should use a consume a tiny amount of power off of the 24vac line, just enough to monitor it. A the output will need to be probably high impedance and interface with whatever the digital IO pin of an arduino needs, current sync or current source. The output will need to b 0volts or 5volts and have conditioning so it&quot;s a nice clean signal.Thanks
