    I want to control a curve led display via bluetooth. I need this circuit powered without connected to any computer etc. so I need batteries or a charger too. I prefer microcontrollers rather than boards for a cost efficient design. No coding needed. Only the circuit design with proper components, a bom list and a report of why you chose those components is asked. I can give the required info of the curve LED in chat. Please ask me for it in your bid.

    I am looking for someone to develop a circuit as per the requirement. It would require two circuits to be developed, one transmitter and one receiver. The receiver will be powered via a lithium-ion battery and should have a charge controller inbuilt. the receiver circuit will trigger a motor once it comes in a range of the transmitter circuit. This is a time-sensitive project so need someone who can start by 27-11-2021. I can provide more details about the circuit and implementation in chat.

    I would like to have two things designed that are based on the paper that you will find attached. 1) A "needle" array in a hexagonal pattern as described in the paper. The difference to the paper would be that the needles need to be a standard, gold coated, round contact pin of appropriate length. Ideally a cheap part available in large quantities. The needle array must be divided into 3 electrical subsets as described. The array must fit into one well of a multi-well cell culture plate. The dimensions are shown in the attached file. The array will be used in exactly the same manner as in the paper, to electroporate cells. The PCB would sit on top of the well of the plate and the gold pins sticking down into the liquid. The pins will need to get within 0.5 to 1 mm of the well bot...
