Some tips on board designing - PCB images

I'm designing a board (with EAGLE) for my first time and, before posting here, I've read some topics and documents on how to design a board, but I still need help since I'm a beginner. My board should power and control 9 solenoids (12V, 2A) and a servo. I will use a board with two layers and 90um. T...

A Touch switch using CD4011

A simple touch switch circuit using CD4011 is given here. The IC CD4011 is wires as a flip flop here. The 9, 13 pins of the IC works as the set and reset contacts respectively.CMOS ICs like 4011 require requires a very low current for controlling its gates. Since the pins 9 and 13 are connected to t...

How to Stacking high voltage and low voltage PCBs

I am working on a project which involves micro-controller and switches (triacs and EM relays). Due to size constraint, I need to stack one over the other. Here is unfinished relay and triac board which will go on top of micro-controller board of the same size: http://i.stack.imgur.com/IpJ6a.png 220V...

Is there any temperature sensor robust enough to be mounted outside a car?

Hello, I am looking for a temperature sensor to monitor the temperature outside a car. The MCP9700 http://www.kynix.com/uploadfiles/pdf9675/MCP9700-E2fTO_912185.pdf would be ok, but I need an enclosure more robust because it will be mounted inside or near the front bumper. Someone can help me find s...
