    I don't see why not. I assume you just use the UART to communicate with it. Adam

    LTSpice switch

    You also have your supply connected to one of the outputs. Can you tell us what it's meant to be doing? Adam

    Your RX/CX does not look connected to the resistor and capacitor?

    floodlight HELP

    Then something like this might do the job. I am sure we can find something in the UK. http://www.aliexpress.com/store/product/AC-DC-90-240V-12V-Buck-Converter-Voltage-Regulated-400mA-Switching-Power-Supply-Power-Adapter-090873/110242_1421810372.html Adam

    Looks different to mine. I typed SW and found this.

    floodlight HELP

    As mentioned above I would use a small transformer or mini PSU which powered on when the main light came on. How much space do you have? Adam

    LTSpice switch

    Hello Did you draw the component yourself? LT has a single pole switch in the misc library Adam

    floodlight HELP

    I think your ok in the UK with blue. I worked for an alarm company many years ago and they had some blue strobes on their bell housings. Adam

    You could use a alarm strobe like this one. http://www.toolstation.com/shop/p28912?utm_source=googleshopping&utm_medium=feed&utm_campaign=googleshoppingfeed&mkwid=fTTFkDxE&pcrid=46334965463&gclid=CO6X7-6-gsICFZQZtAodwFYA8w Adam

    Door Monitor

    Oh sorry I thought he was in the UK. The last time I looked 303 MHZ in the UK was fixed mobile not ISM. Adam

    Door Monitor

    As your in the UK I would use easy radio. I have used these before and they work well. You will need to supply battery power obviously to the door sensor circuit. But this could be just a small micro which controls the UART comms and then goes to sleep to conserve battery power...

    Timer with piezo

    Hello Where do you live? My personal preference is that Forums like EP should remain non commercial and I personally would not make any money out of people on EP. My advice on here is free and carries no guarantee. If I started to do work for people, if I had the time then this work would have...

    does silk screen affect vias on the board?

    Daves right you never know when you might need to connect to a non tented via if you have connection errors. Adam

    Dumb question re. simple inverter

    The MOSFETs getting hot is probably due to them not being turned on fast enough as already mentioned by Steve. Do you still have the large value gate resistors? Try reducing them by a factor of 10. To turn on the MOSFET fully in 1us will require approx. 72mA. If it needs to be quicker then this...

    Thermostaticizing

    Your circuit is a bit jumbled up to be honest. What do you think the 500R resistor is doing? You would also normally rectify any AC signal first before regulating it with a zener. Adam
