Hi All, Not been here for sometime! Most of my project seem to be things? that move, etc. I have for years always used rechargeable cells usually in the form of AA's. I have some old Nicads on their last leg and some new NimH! I think 2700mA being the highest I have. But I have been...

Hi All, Sorry but I've been playing with the Arduino for a time... And find this very useful, it's a tiny PCB containing a chip to control and LCD module via i2c so only 4 wires and 2 of them are power, what a saving on I/O Pins. It just solders in place on the LCD header/strip, they...

Hi, Just installed the new Editor-6! Yes I like it very much but it don't like my Windows 7, 64bit. I can only run it for a couple of minutes and it hangs, to the point the even the Task manager can't fix it and I finish up hitting the reset button on the PC. Some times it will open the...

Hi All, I just got one of these from China, it a i2c backpack that fits on to an LCD (the usual HD477*** type), Great I now only need to pins and not 7 or 8, but How would you program it?? The only other i2c I have used it the DS1307RTC? It says the address is 0x27 would I still use...

Hi, For those of you who might have taken an interest in my Simpler 20M2 shield project, here's my Propagator controller, a bit more then just a thermostat. Depending on the current light levels it sets a target temprature, There's no point in having too much heat if you have little or no...

Hi All, This LCD Keypad looks quite good, especially at £4.55 post free. It says it's designed for the Arduino but looks like it would fit the PicAxe shield!! Has anyone tried it? There don't seem to be any instructions or data as to weather! it's 8 or 4 bits i/f or what pins are use...

Hi All, Not been here for a while! a few months ago I build myself a new PC, I even went legal with a good copy of Win 7 Pro. It works fine, sadly the 3.5GHz i7 Processor still don't seem that fast, even with 8Gb of ram. The problem I have is that if I create a new .BAS file or modify...

Hi, When I first saw the AXE401 shield I got the kit and quickly put it together. But then was'ent sure what I was going to do with it! I would'ent be buying any of those fancy add on shields, but it was the idea of modular units that plug together that I liked. Do I really need two voltsage...

Hi All, Just a bit of fun really. This little game uses an 08M2 Picaxe and a cmos CD4017 which is a decade counter. The 08m2 pulses the 4017's count input and in turn each of it's 10 outputs go high (only one at any time), lighting the connected LED, the Piezo sounder provides the...

Hi All, I have just got myself a couple of nice 200 step stepper motors and want to put them to use. I also have a couple of the old Philips SAA1027 drivers, whcih as some of the older members may recall makes the job fairly easy, in that there are only 2 inputs Step-in and...

Hi, I've been playing with the idea of building a Capacity (and inductance ) Meter, it seems that the maths will be the difficult bit, and perhaps we could do with 32bits.. to do something like 1/(PI*r*c). I know the Picaxe will only do integer, but there are ways around it. So I am...

Hi All, I have just about built my Greenhouse data-Logger, but I think I'll need a bit of a hand with the temp reading with storing and reading it back. I would like to use readtemp12 so need to put it in say (w1), then i2cwrite, mem(%10100000),(w1) then covert it with something like...

Hi Folks, The 20M2 greenhouse data logger is coming along nicely, I hope to record 2 temps (in & out), light. If I get really cleaver even wind speed, etc. While I was looking at the Bitsbox website for a few bits I spotted this Humidity sensor and @ only 80p got a couple, a bit...

Hi Folks, Not been here for a little time? For years even in the good old Z80 days, I've had ideas for a data logger. But now the Picaxe seems to make it all seem so easy?? One problem it seems would be how do I get this data into the PC? I note that on the AXE110 there are 2...

Hi Folks, Not been here for a little time? I have just come across the new 18M2 LCD driver software, must have a go at this. I see you can use a spare output to switch a back light on/off via a Fet, it mentions it being active LOW? Not done a lot with Fets, but don't an N channel...

Hi All, Has anyone tried or even built a capacity and/or inductance meter?? I thought about using some logic gates to form an osc, then putting the test cap CX in parallel with the main cap and noting the change in freq, minus the main freq. If you know the freq you should be able to...

Hi Folks, Not been here for a long time! Redundancy and wife, etc.... I was wondering it's about time I made use of the Picaxe shield kit I got some time ago. But what I would find very useful and I'm sure others would too, is a PCB template in Diptrace, but then how would you...

I have to confess that the original idea for this was not mine, my mate Peter Taylor who has had many years experience playing with electronics, but only a little with the picaxe. Peter came up with this idea for a small PCB that would carry an 08 Picaxe with power and the download circuits...

Hi All, I like the idea of the shield and was quick to cobble it together, and make it do something. Firstly just use an EEprom and flash the on board LED, wait! no you can't do that!! Who put the LED on the 12c bus, could it not just go on a plain old I/O pin like A4,B6,7 etc.. And...
