    Stopping negative voltage

    Hi All, I have a small electronics issue you may be able to help me with. I have an alternator which provides me with an RPM pulse. The pulse goes from 7v to -7v. This feeds a decade counter which in turn feeds my picaxe. It seems that the -7.5v is confusing the decade counter because it...

    Connecting PICAXE to low level audio input

    Hi Everyone, I need a little bit of help with my current project. It's probably a very easy question but not having done something like this before I am really not sure of the answer. I have created circuit for my aircraft. It's just a circuit that reminds me when certain conditions exist by...

    Exporting Netlist to DesignSpark

    I read an old thread where someone was attempting to export a Netlist from VSM into DesignSpark. At that time it could not be done and the final post I saw was that the developers were being consulted to get it to work. What this ever solved and if so, how do you export a Netlist into...

    Components out of limits

    Hi All Just a quick question about VSM. I have had a better chance to use it now and getting to know it much better. One thing I wondered, coming from a different simulation package, is does VSM notify you if you are pushing a component beyond it's design limits. On my previous package if I...

    PICAXE VSM - Clunky or me?

    Just thought I would add a quick post here as I have not long ago purchased VSM. I come from using Circuit Wizard (which obviously doesn't support the PICAXE and is purely general components) and now I am getting back into PICAXE I thought VSM would be a great addition for testing things before...

    Measuring RPM pulses

    Hi All, I have been playing around with PICAXE for a few years but only for fun. Now I have a more serious project to complete but not sure where to start with the code. Firstly, I am not an electronic expert and play around for pleasure and learning. I know a bit more than a beginner but...

    PICAXE-08M and RS485

    Does anyone have any example circuit diagrams on how to connect a PICAXE via RS485. I need to be able to use a PICAXE to detect transmission and also be able to send data. I assume I have to connect this to some sort of RS485 line driver but this is a new area for me so not really sure where...
