    We are in need of an arduino developer who can finish few pending functionality to existing firmware. Currently we have ported our code to platformio using arduino as base. We have a currently working firmware, however we need to add some additional functionality to it. It will be not major changes as most of the firmware is already ready. Major changes needed: 1. Add ESPNOW functionality to our current firmware so that one device can talk with other devices. ( Master/slave config). 2. Send/recieve from UDP server ( mobile app in this case ). 3. Also provide bug fixes after code release. Some other minor code cleanup/standardize and other small changes but nothing major. We prefer a long term person who can work with us for future projects.

    PCB design, schematics and layout needed for basic stepper motor function. Our goal is to have a designed circuit board that will be used to drive an Adafruit reduction stepper motor (or similar motor) at exactly 1 rpm. We currently use an arduino, with the reduction stepper, but would like to create our own circuit board as a more cost effective solution long-term which could possibly fit in a smaller footprint and allow for a more durable and aesthetic build. Ideally the circuit board can be battery powered and contains a flash storage to upload a basic code that ultimately drives the motor. We are open to alternative ideas for how to design a system to operate the motor at 1 RPM. NDA required.

    CALIBRATE 7 ENERGY METERS We have 7 pcs of energy meters, type EH10-DIN Carlo Gavazzi . The 7 energy meters need to be calibrated. Not via electronic programming, but by wiring up at a high consumption cable. The readings need to be higher then they are now. The maximum which needs to be added is +- 20 000 kWh. The various 7 meters need different readings (which we will inform in detail) We can wire the energy meters in series on a small board, so they can be installed on a high consumption cable (max 32 Amps), in order to read the specific amount of kWh. We can deliver a small board, with the 7 meters installed (including the informatuion of which meter needs which specific readings) and 7 buttons to stop the meter when it has reached the specific reading. The meters can have a maximum of 32 Amps. We need to know how long it will take before this job can be done. So you need to know exactly how much kWh passes through the cable. We can pick up the small board when the specific meters have the specific readings. We would like to have the job done asap. We would like to have daily reports of the readings per email or whatsapp messages. Transport costs can be taken care of by ourselves. Please send us a price for carrying out this job.

    I am looking at an FPGA project using xilinx the project has very specific functions that i do not have the skills required to implement it myself sadly so i hope you can help with that. The project is for a crypto miner that can mine using the cryptonote algorithm Variant 1 i have chosen a model of FPGA as it has 100k logic gates and good memory i have estimated the solutions a second for this unit to be around 4000-5000 sols/second which i think is achievable. I have put together some reference material for you to look at to see if you are able to implement it. The project needs to be a complete project from start to finish so i can flash the program to the off the shelf FPGA and set the unit to mine. I have a few ideas that i would like to discuss these include being able to daisy chain the units in blocks of 10 with 1 unit being the control unit that can send and receive data through the ethernet to all the units to handle hash functions supplied by the mining pools and also to make the unit look like 1 unit the reason for this is there is a limit to the amount of connections a pool will let you have before needing a proxy to handle over 100 connections. The unit needs to be able to handle AES, Keccak 1600, Blake-256, Groestl-256, JH-256, and Skein-256 these are the encryptions used to solve the hash functions to achieve a correct answer. It will need a html interface so i can put pool login details into the unit that controls all units. All information is open source so easily available. Reference Material: This is the hash function list for solving the hash for variant 1 Algo [login to view URL] This is how the hash function is done [login to view URL] If you have any questions please feel free to contact me.

    Hello I am doing a small project and am on the lookout for FPGA and software developer to work on a prototype. We are creating a product that is very similar to SmallHD monitors where we take a HDMI signal, process that signal and display that video signal plus overlays such as histograms, false colour and 3D LUTS. What we require for this prototype is the ability to turn these features off and on (Histogram and False Colour) as well as switch between 3D LUTs loaded on an SD card as well as turning them off. Process 1920x1080 HD video feeds with minimal delay. Turning these features on and off as well as selecting LUTs would be done via buttons/switches, no touch screen or other interface required. We do not yet have an FPGA in mind. We would need a development board with HDMI in and out, such as the Digilent Arty Z7. Knowledge of the video processing and features listed above would ideally be required.
