    Picaxe Editor problem

    Upgraded from Picaxe Editor 6.0.6.4 (BETA) because it was crashing on me and I lost edits, now I'm running 6.0.9.3 I get this popup error after programming the 28x2-5v chip I'm working with: "Program Failed Firmware >= B3 Setfreq em64 not supported by this firmware version" Which really...

    Precise output timing

    I've been tasked with building a camera flash delay box with configurable timing and am unsure at this point if it's just for delaying a single flash, or more likely delaying more than one, each with different timings. The hardware I can do ok, but my Picaxe-fu is a little rusty, and I have...

    WirelessThings (Ciseco) radio modules 70% off

    Got an email this afternoon saying that WirelessThings (formerly known as Ciseco) is shutting down and have dropped the price of everything by 70%. https://www.wirelessthings.net/ I bought a few things, sad to see them go, wonder what they'll be doing next.

    Piezo too quiet running on 2x AA's? Try this.

    I bought 6 tiny 3W Class D stereo amplifiers off eBay for the extortionate cost of $2.97 including postage from China (£2.02 after PayPal's exchange rate) from http://www.ebay.co.uk/itm/200932026533 (arrived in about 11 days) I've done a few tests using a 20m2 running off 2x rechargable AA's...

    Parallel task speed weirdness

    I finally have a use for the parallel task capabilites on a 20m2 but during coding I realised something odd was going on, so I did some simple parallel task tests. With 6 LEDs wired into the 20m2 I ran this code: start0: do for b0=0 to 255 next b0 toggle b.0 toggle b.0 loop start1...

    Optimising data comms using ERF,XRF and SRF devices

    If you don't need high speed communication between the devices then go with the lowest over-the-air data rate, 1.2k baud. Ages I made this little vid to show the difference between 1.2k and 250k in terms of how much radio transmission there actually is with the same amount of data within the...

    PE6 editor 6.0.6.4 issues

    I'm trying to get used to this new editor having been used to PE5 for so long and running across a few things that I'm stumbling over, making things take longer than they should to do: 1) Quitting the Serial Terminal asks me if I want to quit, can't find out how to stop asking me every time...

    Sending specific IR codes to a laser tag target

    I was in my local Home Bargains today and saw a shelf full of WowWee Light Strike Targets, aka laser tag targets, for 29p each (yes 29p each!), so I bought one. Closer inspection with a screwdriver revealed some useful salvageable parts: a wide angle RGB LED, SMD stereo headphone socket, couple...

    Problem running 08m2 at low voltage

    My wireless Xbox controller has a habit of turning off if I leave it too long, and online games kick you off if you idle too long, so I wired an 08m2 into it to 'press' a button every minute to stop the controller turning off and stop the game from kicking me out. One small problem, I use 2x...

    Ultrasonic HC-SR04 distance sensor with waterproof sensors?

    I wanted a waterproof distance sensor and figured I could make my own by replacing the 40khz sensors on one of the HC-SR04 modules I have with 40khz waterproof sensors destined for the rear bumper of a car. I got a cheap car reversing kit with 40khz sensors, tested that and it worked fine, then...

    Quirk with resetting the time variable

    There's an odd quirk with the time variable I've noticed once before and now again when programming a countdown timer setup which uses a single button for control. I coded it so pressing and holding the button down for one second turns off the countdown timer, but the time needed to hold the...

    Controlling +V line with a Picaxe?

    I have a Microvision laser pico projector which runs off 5v 1a and I'd like to be able to have an auto-off timer for it controlled by a Picaxe. My initial thought would be to use an n-channel MOSFET to connect/disconnect the ground line of the power, which would be a quick & easy solution, but...
