    PICAXE module boards, tell me what you think.

    I have attached an assembly to a solderless breadboard for Picaze tests.. It has a coax jack for 7-18 v power, a switch and 5V regulator, a DC-9 socket for programming and protection circuit and a test switch. There are also 3 leds with ballast resistors. The wires from this go to the end of the...

    My Picaxe source code

    I have a hobby of making electronic devices, most of which contain Picaxe micro-controllers. I publish descriptions of them in www.Projects.worsleyassociates.com. They include 14924 lines of Basic source code, which may be viewed in scrollable windows and downloaded. Now I am 88 I am putting...

    MPL3115A2 altimeter fails due to software

    I made a board to use as an altimeter on road trips. It has a SparkFun Serial LED display, a Freescale MPL3115A2 on a SparkFun breakout board, and a Picaxe 14M2, all connected via I2C. On initial power up at 3.3V from a regulated power supply. it drew 10 MA and all voltages were as expected. The...

    This handheld RF controller has 53 commands and an OLED display

    I made this for my home automation system which has expanded in the last few years to 10 homemade receivers of various designs and capabilities, most of which are in daily use. I use cheap OOK transmitters and receivers in the 434 MHz ISM band, and achieve reliable and dependable communication...

    OLED Display and ds1307 I2C share a 18M2

    I feared my Maker days were over since I am blind in one eye and the other's lens is plastic. I need challenges for vitality (I am 83) so with the help of a $800 lighted magnifier here I present my 57 th. finished Picaxe project. I was curious as to whether OLED displays were worth their...

    Recap of 18 months experience with cheap 433 MHz Tx and Rx

    I have been replacing X-10 home automation modules with these Wen Shing transmitters and receivers; their models TWS-BS3 and RWS-371-6 which I get from Spark Fun as their WRL-10534 and WRL-10532. Having made 7 transmitters and 10 receivers I have yet to experience a false control action. Two of...

    A Security and Environmental Display and Recorder

    This replaces both a hard-wired logger which has been continuously in use since 2006 and a more recent RF-connected solar-powered logger. Only one of its several components is new, some of them have minor hardware modifications. Its controller, which uses a Picaxe 40x1, is re-used from a third...

    Why did my old system change?

    I have a home logging system which has been running continuously since 2006, and the last modification was in 2010. It has made nearly 6000 files to date. For details see http://projects.WorsleyAssociates.com/Environmental_Logger/ Well at 10:57:06 on Jan 24, 2014 it stopped recording. I did not...

    A multi-Unit Logger

    These are several compatible devices which combine to process analog and digital inputs, convert to a serial digital for, display the values, record them on a Secure Digital chip, and output a selected value to a meter. 1. The Signal Conditioner has convenient connectors for connection to...

    Programmable Current Regulator for LEDs

    This isn't much of a project, but it may be of interest for its use of a LM317 as a constant current sink. This is my 26th. picaxe project posted on my web site, but I don't expect any more extensive ones. My LED Display which uses a second Picaxe to receive IR commands is giving me erratic...

    Strange 18M2 malfunction

    You asked for details .... Here they are The SSR can take care of itself - it was previously used to control a tube-type computer monitor and is probably opto-isolated. It draws about 3 MA The load so for is an incandescent lamp, no precautions are needed, the SSR is a quality Teledyne, rated...

    Strange 18M2 malfunction

    I have a complex project which worked Ok until I put C.0 low (it connects to a SSR) Then it went haywire. C.0 was being held high not by itself, but internally, and it took about 30 MA to bring it down. After checking the circuit, I switched to a spare chip, and that fixed the problem. I...
