    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

    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...

    Battery Charger for 12-volt Gel Cells

    Not as fancy as grimjordax's charger, being just for a single purpose. Our Toyota Prius has a problem. We have no trouble with the big propulsion battery, which holds its charge well, but it also has a small 12-volt gel cell battery (“Auxiliary”) hidden in the back. This battery discharges...

    Antique Bluetooth Speaker

    This is the wooden Art-Deco cabinet of a 1941 GE model LCP-609 AM tube radio, with entirely modern electronics inside. Only the back is not original. It contains a Belkin Bluetooth Music Receiver, a 11-watt RMS mono amplifier, a 20-watt RMS full-range speaker and an open-frame power supply. See...

    Pentagon RF Remote

    This controller is built around the Spark Fun 434 Mhz transmitter module WRL-10534 and six large buttons of different colors. These buttons are distinguishable and attractive. Since they have double-throw switches, the circuit does not need isolating diodes. By using codes provided by pressing...

    Five control projects using inexpensive 433 MHz modules

    These are several compatible devices which use keyed controls using inexpensive modules. They were constructed in order to get experience in using radio frequency communications in PICAXE devices.The RF components use AMK (On-OFF) keying in the 433.92 MHZ ISM band, which may have a range up to 1...

    Wattmeter measures and displays true AC watts over a wide range.

    This device was made to tryout the MC1494 four-quadrant multiplier and is housed in a recycled enclosure instead of my usual handmade oak cabinets. The voltage and current transformers are also recycled. It also measures and displays the mean current and voltage, and calculates accumulated...

    A UPS for PICAXE Projects

    Of course, it uses a PICAXE too, in this case a left-over 14M. Most of my projects are powered either from a vehicle’s 12 V or a “wall-wart” AC power supply, and therefore contain a 5V regulator. To get at least 7.5V at end of life, an 8-cell battery was chosen since a holder for 8-AAs is...

    A temperature display for our spa using a 14M2

    I had to make a replacement for the thermostat on our spa, and I used a PICAXE for it - reported on Sep 12, 2011. As a byproduct, it reports using SERTXD. Our spa does have a Radio Shack digital thermometer but it is not easy to read, and you have to be in the spa. This has a big, bright LED...
