    PICAXE Forum Time

    I made mention in passing yesterday with respect to what I see as the PICAXE forum time relative to reality. All other forums I visit match with my PC, iPhone, watch etc. On all forums, my settings are for time zone GMT+8 and no daylight saving. However the PICAXE forum is seemingly around 47...

    ULN2803A/UDN2981A drop-in DMOS alternatives to consider

    For the ubiquitous ULN2803A as often mentioned and used in PICAXE projects together with its high-side equivalent, the UDN2981A, there are DMOS alternatives available. These alternative parts are the: TBD62083A = 8 channel sink type DMOS transistor array TBD62783A = 8 channel Source type DMOS...

    PICAXE based DCC Accessory Decoder

    To meet my own needs and in response to a number of past threads inquiring about PICAXE based DCC decoders for model railways, I present my own PICAXE based DCC Accessory Decoder. Developed initial on a breadboard and I have subsequently constructed a couple on prototyping boards which are...

    PICAXE based Model Railway Speedometer Wagon

    I know there are a number of model railway enthusiasts lurking out there. Some may find this small project of interest to construct a PICAXE 20M2 based Speedometer Wagon either just to know what the scaled speed is for a locomotive or wishing to calibrate the speed. While the program is...

    Getting Started with the DS3232 RTC and a brief comparison of some other RTC chips

    Having bought a DS3232 some time ago and after getting it up and running (a relatively easy task), I started on the attached information back in March but it fell by the wayside for a while (starting paying work with longer hours on a new multi-billion $ project for one). Have wrapped up some...

    Hantronix LCDs - Specifically HDM20416L-1 and similar with KS0066U controller chip

    I was recently given a few 20x4 character type LCD modules by our IT group from some Equitrac systems that had been decommissioned. These 2002 vintage modules have a Hantronix HDM20416L-1-Y1ES display using a KS0066U controller chip. See: http://www.hantronix.com/page/index/products/character...

    Calculate Cube Root to 2 decimal places

    As a follow on the my past calculation of a square root for values (0 - 65535) to two decimal places, I have prepared a similar piece of PICAXE BASIC code to calculate the cube root of a value (0 to 65535) to two decimal places. I stopped at two decimal places as the maths is at 2 decimnal...
