    Quick Charge 'Trigger' Board.

    What's a Quick Charge Trigger Board, I hear you say :) The Qualcomm Quick Charge protocol is implemented by a variety of 'USB' Chargers and (more interestingly, perhaps) Power Banks. They are intended for 'quickly' charging Mobile phones and Tablets. This is achieved by increasing the voltage...

    New forum software + "Copy for Forum" function in PICAXE Editor

    Is there a way to make code copied from the PICAXE Editor (6.1.0.0) (Using "Copy for Forum"), display properly in this 'new' forum software? Previously, this :- if b9 = "0" then b9 = " "...

    Strange PWMOUT behaviour - can anyone explain it?

    I have an old project, that I have recently been doing some work on: it's a 14M2-based 'Battery Capacity' tester. Basically, it uses various PWM settings to drive a MOSFET (via a resistor and capacitor) to achieve controlled discharge currents, with the attached cell run-time measured and...

    Serial over Ethernet (Program Picaxe connected to another computer over internet)

    Is the "Serial over Ethernet (Program Picaxe connected to another computer over internet)" feature currently functional? The Help file tells me to use the "Wizard" within Programming Editor, but I can find no "wizard" as such, just a Config. program (which asks me questions I don't know the...

    Picaxe X2 SETTIMER CPU overhead

    In another thread, there was the following conversation :- I was idly curious, as to the size of this overhead - so set about measuring it. Initially, I used a simple 'Toggle B.1' in a loop, measuring the achieved frequency on a 'scope vs different values of TIMER Preload. The effect...

    31KHz Watchdog reset ... but for no obvious reason

    I have some code running on a 14M2, that is triggering the 'well-known' 2.1Sec Watchdog Reset when running at a clock speed of 31KHz ... even though it doesn't take anything like 2.1 Seconds to execute :confused: This is the code :- setfreq k31...

    Hope RFM210LCF-433D-A

    I know that not all 433MHz RF Receivers are created equal, so when I needed one for my latest project, I made sure I chose a Superhet version, over a TRF design. One of the first ones I found on eBay, was a Hope RFM210LCF-433D-A. Being branded and reasonably priced, this is the one I chose...

    The care and feeding of Triacs.

    In the next phase of my project, I want to trigger two Triacs to control two 1KW heater elements. The elements are physically inter-connected and the centre point is currently used as the Neutral. The elements will be switched on either together, or separately for several minutes at a time...

    O.T. Cheap Component tester/identifier

    I just came across this little module on eBay (while researching methods of measuring inductance). It seems to be more of a functionality tester than a precision measuring instrument, but at the price, I had to have one :D EEVblog video review: https://www.youtube.com/watch?v=7Br3L1B80ow An...

    BINTOASCII Implementation change...

    I just loaded a source file that I created under PE5 and found it will no longer compile. It does still compile and download using PE5. Is this behaviour configurable in PE6? This code:- bptr = ByteArray W0 = Time / 60 ;Convert Seconds to...

    Audible noise from an SSR!

    I've never actually used an SSR before - but I'm pretty sure that 'clicking' noises emanating from them, wouldn't be considered normal :confused: The noise stops if the load is disconnected. Anyone know what's going on? (The SSR is being used as part of my 'Fan Heater' control experiments...

    Controlling the speed of a Fan Heater motor

    I'm embarking on Phase 2 of my project to enhance the temperature control of a Dimplex Oakhurst heater. Phase 1, published HERE makes uses of the heater's Infra Red Remote Control functionality, and is a vast improvement on the in-built mechanical thermostat. However, the Fan - when it is on -...

    Picaxe 20X2 unrequested RESET @ 31KHz, using LOOKUP

    Probably not a combination that happens very often, but the following program demonstrates an unrequested RESET @ 31KHz, using the LOOKUP statement. I've only tested it on the 20X2. It works in the simulator, but not on the real chip. #picaxe 20x2 #terminal 9600 #no_data ; Demonstration of...

    14M2 TABLE data

    I've recently been porting some code from a Picaxe 08M2 to a Picaxe 14M2, because I'd run out of memory (it's a WebServer implementation). The intention was to make use of #SLOT 1 on the 14M2 to effectively double the amount of memory available (and get some more back because EEPROM doesn't...

    6.0.9.2 Resource Usage

    I have a strange issue with Picaxe Editor 6.0.9.2: the longer the program is left open, the more sluggish it gets - finally reaching a stage where it can no longer keep up with key strokes. A restart cures it for a while. The problem seems to occur with 'time' rather than 'usage'; i.e. I can...

    HTU21D Humidity / Temperature Sensor

    I have recently started to investigate the HTU21D Humidity / Temperature Sensor - having found them on eBay for only £1.90 each. (That is, mounted on a PCB with SDA/SCL pull-up resistors, but no regulator - so strictly 3V only). At that price, they are cheaper than DS18B20's (which of course...
