Hi Ciocan, Can you make new part drawings in EagleCad? I have Eagle 6.6.0 Professional and design a lot of boards, but I cannot figure out how to create my own parts. I'd like to find somebody who can do that for me when I find new parts. In this case, it's a simple switch from E-switch, part number EG2659DKR-ND with holes in the PCB to align the part. Let me know if this is something you'd be interested in. Thanks, Mark

We have a spinning display (prototype) which has a 7" display, motor to spin our product and using an Olimex board to run the video / audio. We have successfully prototyped this and now, we need a freelancer to optimize this design and prepare it for manufacturing as the cost is too high using the Olimex board and the associated 7" LCD/controller board. We are using a standard microwave oven motor to independently spin our product and this is directly connected to a switch and powered directly to an AC power source. The motor turns 360 degrees and then automatically reverses since we have created a mechanical stop. The way the unit will function is as follows: 1) User will turn on a power switch located on the bottom of the display 2) Display will provide power to the motor which will start spinning and simultenously power the microcontroller board to run the OS (i.e. Linus/Android). 3) OS will initiate and the user will see a splash screen which will allow them to e...

In a nutshell, here is what the electronics need to do: 1) The camera shutter is opened through a push lever. It actuates a switch - signaling the processor to start measuring light 2) Light measurement gets converted into a usable value and exposure is calculated based on other parameters (focal length, pinhole diameter, reciprocity value, EV compensation, and constant) 3) Light measurement is taken every second to account for lighting condition changes - Pinhole photography exposures tend to be very long 4) Once proper exposure is reached - circuit actuates a servo to release the shutter lever which closes the shutter through mechanical spring energy. The servo just needs to tal the lever to release the mechanism. The APP would have a databese of films, constants, etc. and provide camera the selected data to the circuit (pinhole diameter, dilm, EV, focal length). The circuit in the camera will keep this data and use it to calculate exposure. Current design has a screen built in and...

Our product will monitor soil conditions and perform actions based on the measurements. Using an app (Android, iOS, and web based), users can specify triggers for notifications when the soil is outside of the acceptable range (for example, if the temperature is approaching freezing, or soil pH is getting too high). The app will also access the historical data that will be stored via the web to track growth and associate pictures taken. We would like the device to meet the following requirements: Sensors Temperature:range from -40 to 140, accuracy of 1 Humidity: range from 0 to 100% RH accuracy of 2% Barometric pressure Light intensity: range from full daylight to night using photoresistor or solar panel to detect Soil pH: range of 4.5 to 9.5 pH, accurate down to 0.5 Enclosure Waterproof Weatherproof & UV resistant 3"x3"x2" maximum dimensions (not including any probes that would go into the soil) Replaceable battery (AAA or AA size) Data The device should tra...

We are developing an integrated circuit board for remote data acquisition, and remote control of solid-state relays, for solar power systems in remote, off-grid healthcare facilities in sub-Saharan Africa. We call this circuitry the RMC Unit (Remote Monitor and Control). We have engaged a PCB design company to design the board. The RMC uses a variety of sensors to gather necessary data. Today. we need help in determining which sensors will be used, so that the PCB design firm can select the correct ports. Further, our in house team lacks experience in PCB design. We need someone with extensive experience who can answer questions and offer guidance. Experience developing relevant circuitry is crucial. Experience with sensors (voltage, current, and temperature) is important. As are basic programming skills. We are looking for an on-going working relationship. We expect to have further technical hurdles in the coming months for which we will need help. Feel free to contact ...
