    Im loooking for an experience CFD Engineer to perform a CFD analysis of a small cooling device im creating on 3D. The device is using the airflow for cooling. Its cooling capacity should be investigated, and having that in mind, the motor power/ fan size should be adopted. You should have in mind the common temperature range of the units to be cooled, and preferred temperature range to be achieved. You will also need to investigate the electricity consumption,the ...

    I am interested in getting a circuit board and necessary software designed to control a very small rotary motor. I am building custom automatic air fresheners and I would like to use a similar type of circuit board used in a Glade or Airwick automatic air freshener. The key features for the circuit board are: control the rotary motor to spin on intervals with a toggle type interval selector with 15, 30, 45, and 60 minute interval settings including an ...

    I am looking for someone with in-depth expertise in Bluetooth protocols, especially in programming for using HCI modes. The goal is to connect a microcontroller system to a Bluetooth HID device (a keyboard for example) using a Panasonic PAN 1026 module (with Toshiba TC35661 Chiron chip) through a serial line. The details will be discussed once the credentials of the applicants meet the initially desired depth of Bluetooth knowledge and the experience via applicants' profile. If you do not already ...

    Hello Fritizing Master! I am using Fritzing for a small prototype I am building and have parts that I ordered from a small manufacturer that have no fritizing equivalents. This makes it hard to create an accurate prototype PCB. Parts are 1) 4-connector USB charge board 2) 8-pin SMD FFC to FPC LCD connector (.5mm and 1.0mm) Possibly one or two more The task here is to create these as fritizing parts so I can include them in my ...
