    pulsin for Model Radio Control.

    I've used pulsin for lots of my RC projects, with great success. It works fine as long as the program is not too long. Am I right in believing that I can't use the servo command because I'm using the pulsin command, something to do with internal timing. Is it possible to use multiple interrupts...

    miniature boiler sight glass low water alarm.

    Hi Guys, I need to detect the water level in a sight glass for a model steam boat. I could use a probe fitted into the tank, but would prefer to clip 'something' onto the sight glass to detect water low level. The sight glass is 5mm o/d. Any idea what the 'something' could be? thanks TOF

    Advice Required for Connecting multiple picaxe over radio link.

    Hi Guys, With reference to my project, large miniature railway. I've been asked if the signals can be controlled by radio link, ie xbee. I have read the Xbee tutorial and datasheets. So I have a few...

    help needed with I2C

    Hi Guys, I've been asked to look into a project to control a minature steam railway signalling. I thought of using a number of 40x2 and 20x2 chips. Interfacing between the chips using the I2C bus. I've downloaded the tutorial and read it more than once. Is it feasable to think along these...

    Help required, simulate variable diesel engine noise.

    Hi Guys, This is a project for one of my model boats. How can I replicate the sound of a diesel engine noise using an 08m2 picaxe. It needs to vary with the speed on the boat electric motor. the easy bit is reading via the serin command to detect the speed. the hard bit, which I'm struggling...

    Must be a shorter way.

    Hi Guys, Is there a better / easier way to program this. Its to show water level, sensed by sfr05. lower the distance, higher the level. Only showing relative parts. #picaxe 40x2 symbol oled=A.7 symbol baud=n2400 ;bargraph setup CGram serout oled,baud, (254,64,0,0,0,0,0,0,0,21) ;0...

    multiple Pulsin

    Hi Guys, Before I put an order in for the chips, can you check my thinking please. I require 3 'pulsin' inputs, from a radio control unit. (from spare inputs on my model boat RC.) The pulse width of each input will determine what happens to a bank of relays and/or opto isolators. If I use...
