Hello all I have not tinkered with my Picaxe ICs for quite a while, so last night I thought I would break out the Axe091 and connect up an LCD to a Picaxe. Yea... this box of Picaxe chips are dangerously near going in the bin Started with a Parallel LCD that I know worked, but after an...

Hi all I basically abandoned Picaxes due to the constant programming issues I was having. One minute it could find the chip, next minute it could not. Returned to an 08m2 today, and on a new Asus laptop.... it found the IC straight off the bat and loaded my program. Great! Then, 2 minutes...

Hello folks I know best part of nothing about batteries, so this is all new. We need to charge a tiny Lipo battery like this... http://www.adhiratech.com/index.php?route=product/product&product_id=2514 and I was thinking of controlling that charge with one of these...

Hello everyone. Anyone got any idea what the part in the middle is? 356A7 is what it looks like to me, but I cannot find reference to it anywhere. We have a pcb where one has been broken off, and I need to source a replacement.

Hello all OK, Starting a new thread on this one. I work in special effects. Mainly Pyrotechnics, but quite frankly... anything and everything gets built. It's always last minute, and the deadline is usually yesterday. You have to think outside the box in this field. I need to design some pcbs...

Now deep breath... lets not rant... I have had to finally abandon my Picaxe. I just cannot justify the maddening amount of time I spend faffing around with drivers trying to get my computer to see the IC's. Again, this morning at work, the latest programming software was showing the device on...

Hello all I have been playing around with a couple of ESP8266 modules. All lovely and fun. Got a local network established etc. I am trying to basically transmit some basic data from equipment spread over a warehouse. Collect that data and send it to a webpage. My basic webpage system...

Hello all I have an MPU6050 gyro sensor board (marked GY-521) that I have connected to an 18m2 via I2C I got this board 'kinda' working a long while back, and now I have need of programming one into a project on an urgent basis. Anyone know of any base code available to get me off the ground...

Hey all I bought a hand full of these cheapy buck bang converters off Ebay.... seem pretty good. Are they reliable enough to power an 08m2 off a variable/unstable 24v? How good are they at actually providing a noise free supply to a Picaxe? The 24v in question is a battery, but its in a noisy...

Hello all I have a rather nice LED worklight that my wife blew to bits yesterday by plugging in the wrong charger (12v instead of 6v charger). PCB has disintegrated to a point where I cannot determine half the components, and the tracks have also lifted. So... took it apart to form a plan...

Hey all. Been Googling a while looking for details or a circuit diagram of a digital train controller. Wondered if the good old Picaxe could come to the rescue in some kind of way? Was basically thinking of some kind of PWM motor receiver controller that can read the overlaid signal on the 12v...

Hey all. Not sure if this even counts as a Picaxe project... but you guys are the ones to ask. I have a customer with an NVR controlling their CCTV system. They have several unused POE ports on the back of the machine, which then leads to blank images on the main viewing screen (no combination...

Hey all I have an 8x key keypad that is connected to a 40x2. Because I don't have enough pins, its been set up with button 1 as a short to 5v, and then varying resistances over the other 7 buttons to give me a reading on an ADC input (0-1024). I worked out the values, set a slight 'window'...

Hey all. I have a complicated circuit. Basics... 40x2 running a Max7219. This Multiplexes 60 leds inside illuminated buttons. I have tried to keep the MAX7219 near the IC, but it wasn't possible to have it on the same PCB. So its about 10" away, with its data lines run in a screened cable...

Hey all I have a 40x2 in my truck controlling all the lighting.... worked fine for 5 years. Yesterday the garage broke it. So, trying to re-upload the 4x slot program to the chip and I spent the last 3 hours trying to do it. Just about to put a hammer through it. First of all... took 2...

Hello I have an MCP23016 I/O expander chip running on I2c. Its got 16 input/outputs. I have these wired as an 8x8 button matrix (8x outputs, and 8x inputs). I am using 8 pins as outputs for columns and 8 pins for inputs as rows. 64 detectable buttons. I am sequentially taking each of the...

How come the cost of Picaxe chips hasn't dropped? They seem to have been the same price forever. I need some 08m2 chips for my project, so chucked 4 in my basket in the Picaxe store. But, once the vat and shipping are added, they just become expensive for an 8 pin devices . It was £7.52 for 4...

Hey all I am driving a piezo directly off an 08M2 pin using the sound command and its pretty distorted. Its one of those small encased types you see in alarm keypads etc- about 10mm diameter. Mounting on the case has not made it better. Tried a couple of other piezos - same issue. Resistor in...

Shout toward the clever folk... I have a USB microphone here that doesn't have a lead. I found an XLR plug and an old USB 4 core lead and assumed I could make my own. Lower left hand connections appear to be the 5v supply, no problems there (I don't think). The SMT fuse is ok (the microphone...

Hey all I need a system where I can play multiple sound files at the same time (through a low quality mixer). Basically, I need a background 'engine' sfx, with other effects overlaid on top. I am thinking of these: http://www.ebay.co.uk/itm/291956275599 However, the cost jumps up pretty...
