    The project: To design and prototype PCB and circuit with great attention to low power consumption and low component costs. Stage 1 I have 2 micro gear brush motors that will be running on 6v dc (4X AA batteries) they use 40ma on free run and 700ma at stall, these will be fitted into a unit called project X I need to be able to control them by remote control both forward and backwards so I assume that would be ...

    I have a circuit schematic that I did on eagle. I want to make sure that there will be enough power for all of the components, that I have the components hooked up correctly, and make sure that there are no shorts. I have datasheets for the components I am using. If a component needs to be replaced, I would like to know which component and where I can find it. Also, if the voltage is incorrect, I would like ...

    I need a very simple box or part that beeps when a circuit is competed. This is how it needs to work. A box/part has two wires one on each end, when you connect the wires together I need to have a constant beep. Please look at the attachment if you have any questions I am looking for a design that is VERY simple to make but VERY professional looking. This is what I need 1- design including PCB ...

    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 ...
