    I WANT THIS DONE AS CHEAPLY AS POSSIBLE, BUT HIGH QUALITY.Must have strong experience in building Bitcoin Mining Rigs/machines. I want someone to build me this mining rig. You must have the following1. Access to your own asic chips - project new 20nm or 28nm ASIC 100Gh/s or more if can. See example pdf: http://23511.linuxpl.info/pdf/minion_preliminary_datasheet.pdf ( but is 28nm 100Ghash, I want more Ghash if can and 20nm )2. Boards PCB layout with ASIC chip (for 3000Ghash - 10000Ghash if can more )3. Fans for chip ASIC4. You must have the items to make this machine, or have access to the materials to make this mining rig. 5. It can be an open or closed rig or rack 4U6. Upon completing this unit, and everything is running smooth, I will be contracting you to make another 500 mining machines. I CANNOT STRESS THIS ENOUGH, IF YOU DO NOT HAVE THE MATERIALS, OR ACCESS TO THEM THEN PLEASE DO NOT BID. READ EVERYTHING BELOW BEFORE BIDDING!_______________________________________________________________________________________________________________________________I WANT THIS DONE AS CHEAPLY AS POSSIBLE, BUT HIGH QUALITY. I know the few companies that are out there making these mark the prices up high for the profit. I am ok with you making profit, but you have to be reasonable. I know a company is coming out with a 2000 GH rig in a few months, but I do not want to wait on them. Their price was in the $4,000 range. I am looking for below that, or around that price? _______________________________________________________________________________________________________________________________Some specs--Some items may vary, just let me know what you are thinking and how you can build it.

    hi there, i already posted this Project separately but didnt get satisfying results. i work on the pcb to facilitate the Task: i replaced the 1st digipot with a true 24bit dac. if you like another type, tell me pls.as the digipot only likes 5v max, the voltage should behas been reduced to 5v on all opamps for the new function.big opamp has to be chosen to drive the galvoi use eagle, you can download it for freei would like the device have its own ip and work wireless. the current atmel only allows a transmission of ca 1000 lines per second @30 bytes due to latency=unacceptable.you can put out half of the opamps of the new function. push everything together, space is available.fr4 - 2 layer as is.the galvos Need a high accuracy, so you Need to check the design.please: no comments: &quot;i can do that!&quot;. i received 20 offers, and after all, nobody could give good answers.so please write to me: what opamps would you choose, what dac (if you want to replace it), what galvo power opamp? you would Need to give me the Impression you know what you are talking about. i already lost three weeks with pretenders, that´s really enoying. i Need an analog specialist for the galvo function, and an mcu pro for the atmel chip replacement Task. please please dont let us waiste time with &quot;i can do it&quot; mails. send me good answers to Show me you really can do it. pcb layout attached.can you also write the firmware? make 2 pcba samples? or even do the user interface? just curious;-)

    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.

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
