    Hippy status, rev 2.0

    I can only say I was not expecting that. In New Zealand, we have been relatively safe and hence underestimate the impact the virus has had on friends from overseas. Reading about Hippy woke me up a bit and reminded how lucky we are down here at the bottom of the Pacific. I hope Hippy recovers...

    Choice of Display module.

    Thanks lbenson, the 'Picaxe M2 Summary' would have been a good place to introduce that feature. But, my question is, how do you guys simulate code that runs across 2 or more code spaces. I will have to put my main code, assignments and definitions in slot0 and jump to slot1 for menus etc. Would...

    Choice of Display module.

    Thanks lbenson, I was being a bit dramatic using the word 'secret' but would like to see more presence and explanation in the documentation. Maybe it has sufficient explanation but as an old fart I sometimes gloss over the bits I don't fully comprehend. I must do better. It has made so much...

    Thanks Aries, I had seen reference to the second code space but did not find much in the way of documentation. However, now it seems it is so simple and I wonder why it is kept a secret. It seems not much is said about techniques and I assume it is not supported in simulation. Thanks again, it...

    Thanks for the advice, starting research now. Regards, Kevin Thompson.

    Thanks Buzby, you have encapsulated the project nicely, I had purchased a couple of "I2C 1602 LCD Board Module 16x2 Character LCD Display Module HD44780 Controller " but had no luck getting meaningful output. I can set the full range of parameters needed from setting time to selecting outputs...

    Choice of Display module.

    I have written some code for and built a universal 8 port timer using a 20m2, an RTC module and 2 x 4 way relay boards. I have been adjusting the sequences viewing the output via the serial terminal. I would like to include a 2 line led display so users won't need to learn how to program it. My...

    Open Source Ventilator Project

    What a good idea. The PicAxe is the perfect controller for such a project, low power consumption, completely customisable, cheap and simple to implement. The range of sensors available covers all the basic requirements, and the output options equally useful. This was some way down my list of...

    Mouse without Borders

    That's not a problem, each machine works as normal and as soon as the other is turned on the mouse can then move across to the other computer's screen. Once that happens the cursor for the second machine disappears and you only have one to worry about. It is so well organised that although this...

    Mouse without Borders

    According to the comments I have seen, it works through wifi and wired connection to router, which is what I have. Basically, if your machines are connected to a common network either by wifi or cable then it will find the other machine/s. Install it on one machine and record the password and...

    Mouse without Borders

    I am not too sure where to post this but the Microsoft Utility called "Mouse without Borders" is so worth having a look at. It is a software KVM utility, written by Microsoft coders after hours. I have a machine with dual screens and another with one. Run this utility and the mouse just passes...

    12v motor switching advice

    As a retired Auto Mechanic, and avid experimenter, I can assure you the small motor load would be nothing to an auto relay of the type used on headlights etc. The inductive load may require a capacitor across the contacts whereas a resistive load like lamps would not.

    12v motor switching advice

    I did some experiments using logic level MOSFETs, directly connected to the PicAxe output pins, driving a 50w spotlight lamp. The main thing I was interested in was volt drop across the MOSFET, which I found to be so low it was not a concern. The dissipated energy only just slightly warmed the...

    No, I had a breadboard mounted 5v supply.

    Traps for young players

    Hi Y'all, I have spent months writing code to run my irrigation system and was using Sertxd(..) to debug. When I programmed the chip it went all wrong. certain lines of a loop would not print and this pattern was repeated (same lines every time) identically every time I programmed it even with...

    Automotive ignition pulse sensor

    The back EMF generated in the primary circuit when the secondary's magnetic field collapses across the primary windings can be as high as 500v, that's why there is a capacitor across the points, to absorb this spike. With the 'old style' points system (known as a Kettering Ignition system) the...

    Automotive ignition pulse sensor

    20 years ago, I found a gadget at work which I believe was an over rev indicator. It was in a small plastic box about the size of a matchbox. The pickup was 3 turns of average size wire around a high tension lead. It only had 3 or 4 components and it turned on an LED when the engine revs reached...

    To poll RTC or not to poll RTC

    Thanks Aries for this and the other post, more food for thought, I thank you all for taking the time to look over my rather messy code. The matters you mention are now on my list. I have taken it all on board. Regards, Kevin.

    To poll RTC or not to poll RTC

    Thanks, this too will be added to my list of optimisations to be considered. This is all invaluable stuff, I can't understate how ,much I appreciate the advice. Regards, Kevin.
