    Picaxe on a LiPo rechargeable battery

    My latest project must run om a Lipo batterywithout internal protection circuit Charging will be done by a chinese circuit costs €1.50 and has a protection circuit, charging the LiPo to 4.2 volts max. That's the easy part. Discharging is a bit more difficult because 3.0 volts is the...

    Losing axe027 while using debug

    Hi When I use debug commands in my programme, sometimes but frequently the PE looses settings for the axe027. It happens when I hit the download programme while receiving debug data from the picaxe this happens. Reconnecting the cable and discover it again helps until the next time As...

    PWM for regulated power supply

    Hi folks, I plan to build a picaxe controlled power supply 0-30V and current limiting 0-3 amps The picaxe will have to deliver 2 separate dc voltages (1 for voltage, one for current) Is this possible? I get a bit confused but learned a resolution of 1024 is possible. Voltage regulation (about...

    Egg Incubator based on '08m2

    My daughter started a project at school where she wants to develop eggs to little chickens. I helped her to design and build the incubator. I also built the thermostate using Picaxe, thermo sensor and OLED display. Output is using a relais because the heating draws 240 watts of power. There is...

    Creating BMP (picture) files

    Hi all, I am planning the build of an Infrared temperature scanning camera. I want to use 2 servo's to pan and tilt a pyrosensor. There will be a fresnel lens in front of the sensor to focus. This way I can generate a value for any given point of the subject together with the x,y coordinates...

    axe133 not hwserial...

    I just received my rev-ed's stuff and started to work with the 18M2 combined with the AXE133y (OLED) First.. Yes! The OLED looks incredible (once you go... :-) ) First thing to do was to alter the code to 9600 baud... A simple "hello world" program worked fine on 2400 baud but not for 9600. I...

    Vmusic2 5 V savvy?

    I bought a Vmusic2 a long time ago and got it running on the serial cable. I didn't complete managing it using the picaxe and it went into the closet because of time constraints : Now I want to fire up this project to make a MP3 player with (oled?) display to connect to the main room stereo. I...

    stroboscope for classic combustion engines

    Hi all, As a proud owner of a Honda CB500F1 (1976) I was looking for a stroboscope to set the ignition timing right. A simple stroboscope will cost about 60-70 euro's and will do the job fine but much more fun it will be to build my own, using a picaxe of course! The stroboscope itself is...

    Escape from gosub without using return

    Hi all, I am building a stroboscope,dwell and tachometer using a Picaxe 18M2. This is a tool for adjusting the ignition timing on classic motorbikes (or cars if you like them more :)) It has a power LED (RGB LED) fed by a FET transistor. There are 4 buttons (menu,-,+,OK) and 1 8 digit starburst...

    Lightautomation for semi public sport facilities

    At the stables our horse stays, there are some facilities available where users can switch the mercury-lighting themselves. However, often they forget to switch it off after use or, when they switched off, the next user has to wait for 10 minutes for the lamps cooling down before they will...

    18m2

    I read the specs for the new multicore 18M2 picaxe but I can't find how the cores interact. I am thinking about using 1 core for timing and the core routines, another for user input and sensors and a third for display. I understood the b1,b2 etc variables are local per core but are 'global'...

    Some chips show 'discontinued' in PE.

    Because I ordered the new 20x2 Picaxe, I needed to download the newest PE. No problems downloading and so on (as usual) When selecting the chip I saw (amongst others) The Picaxe 40X is discontinued. Since I have some of these, using them for experimenting purposes. Maybe I better put them in a...

    BAS0800 programmer

    Hi all, When using the BAS800 programmer, I should be able to program PIC's directly using the built in assembler (still writing programs in Basic) Questions: Say, I have a program 'saved' in a picaxe and the same in a PIC, will the PIC controller act faster? Do I have to set 'fuses' and...
