If you wanted to make a 434MHz transceiver for PICAXE using separate Tx and Rx modules what's the best method of allowing them to 'share' an antenna? I know little Tranceiver modules are available but they don't do what I want. (I'm only talking about tiddlers here. 25mW Tx power max). Thanks.

Has anyone had the following wierd thing happen with ADCs? Circuit: (using an 18X). All 3 ADCs connected to 'slow' inputs (measured voltage ranges 2 to 4Volts). PSU is well regulated and smoothed. Direct measurement using a DMM show the input voltages behaving as they ought to. But something...

Has anyone had real-life experience of the USB MM232R convertor module from Future? http://www.ftdichip.com/Products/EvaluationKits/MM232R.htm I won't be programming via it, just simple data transfer from PICAXE to PC via USB. I would be very grateful for info on real-life issues rather than...

Does anyone do a software loader type thing for PICAXE? e.g. so that you can give a software update to someone to load without them being able to copy/crib/criticize your code. Its also handy if a colleague needs an update but doesn't have the Editor. Especially if the colleague likes dabbling...

Are the inputs (all/some/none) on the 18X or 28X Schmitt type or simple TTL? I got a little confused with the Microchip data sheet dc & AC Characteristics section. If so, has anyone checked the Input High/Low voltages in real life?

I haven't looked for a while so I was wondering if there had been any progress with 08Ms and having their BODs off (or user settable) to get micropower consumption?

My query is about 'excessive' power consumption of a PICAXE-08M. Setup: PICAXE-08M in the little demo board. No Loads. 8 lines of code with a 'Sleep' statement. Measured power consumption ~0.4mA . Note: Under the same conditions a PICAXE-18X was using about 8 microamps in Sleep. And even the...

Can anyone help a PICAXE new boy please? I am trying to design a little circuit using the PICAXE-08M. I have been prototyping using the little demo board. I need it to consume as little power as possible. And as it only needs to do things infrequently I can do a NAP or SLEEP. But with no loads...
