    I am building a very small circuit for controlling my 3 watt lasers. It involves a surface-mount picaxe 08m2. It is very weird what is happening. I know i have made a wiring mistake somewhere as the picaxe is drawing 200mA and gets to untouchable temperatures in seconds. Heres the weird part...

    How to connect higher voltage to input reliably

    I have been working on my 3000mW handheld laser monitoring system for ages. It is a picaxe 08M2 connected to an LED, a buzzer through a transistor, a thermistor, and an 8.4V input. It is almost perfect, the problem I have isn't really serious, but I want to make it perfect. Now read carefully...

    I2CSLAVE OR Background serial between 20X2 and 20M2

    Basically, I have a sensor unit and a display unit. The sensor unit gets temperature from DS18B20, light from TSL235R, and humidity from HH10D and stores the values for retrieval from the display unit. The display unit retrieves the values from the sensor unit and displays them on a 16x2 serial...
