I provided a lighting kit for a customer a month ago and it was working happy as larry during extensive programming and testing. The 18m2 low power board (CHI030). However, they ran it for 10-15 mins and the capacitor got very hot and then nothing worked. I've got it back for testing / fixing...

Hi, I need to use the DF Mini audio module (SPE035) with an 18m2 low power board as the low power board has the voltage regulation required and other bits I need. Anyway, to keep it simple, does anyone know what pins I need to connect the module to to work with the 18M2? I know it's '+'...

I have created several PCBs in the past through DesignSpark PCB for SEEEDStudio manufacture but this time I'm having a problem where when I view the Gerber files, via an online Gerber viewer (tried several including SEEEDStudio EasyEDA one on uploading to manufacture) and the drill files are not...

Hi all, I've got the SPE035 MP3 module with the associated AXE171 14m2 board working nicely but I want to do what I thought was simple and flash the two onboard LEDs once every 2 seconds. The problem is I can either 1) flash the LEDs 2) play the mp3 but not both together. I've tried loads of...

I needed a very small PCB for a commercial project. I have started designing my own PCB's and have a few successful ones incl the download socket but this one without it isn't working. I have included the decoupling capacitor and the minimum pulldown resistor on the serial in pin (33K). I've...

This might be a bit of an unusual one but I have a macBook Pro and so use the MacAxe software and have no problems at all with programming the 08m2 chips. With the 18m2 I quite often have to try several times to get it to programme, despite it working fine just before and it's also associated...

I have another issue related to some of my recent threads for programming flickering Lights on the 18M2 high power board. The idea is to have two channels so you get different flickering over 24 lights (two sets of 12). I want to put them through the onboard FETs (rather than one set through...

I have been trying to improve code so that it will check for an IR signal on button press while the action is being carried out. eg, I have a flashing light in a loop but I want to exit the loop early if another button is pressed. So far, the only way I can get it to work consistently is to...

I contacted Picaxe about upgrading the FET's on the 18m2 high power project board and they said it should be fine but to ask on here in case anyone has already done it and can suggest the right FET's to use. They pointed out they may need heatsinks if going a lot bigger. Basically the PCB has...

I searched the forum but didn't find this. Can someone clear this up for me. I've always taken the maximum current of the darlington drivers as used in the project boards as 500mA maximum total current and that's what I've always understood, but if you read the datasheet it's a bit confusing...

Hi all, I've had an enquiry as to the possibility of controlling the speed of flicker using a potentiometer for dolls house fireplaces / candles. They've seen an available unit (probably from China) and asked if I can do something similar. What I'm using: PCB: 18M2 project board / high...

Hi all, Can anyone recommend a tiny electric motor to run off a picaxe chip? It doesn't need to be able to carry any load as such. I'm building a plastic model kit of the Starship Enterprise from the 2009/2013 Star Trek movies and the on the warp nacelles, at the front there is a bussard...

Hi all, I've got a question about the CHI030 project board (18m2) http://www.picaxestore.com/index.php/en_gb/picaxe/project-boards/chi030.html I am using it with the 5v regulator and a 12v transformer but when I check the outputs with a multimeter I'm only getting 2.44v through the darlington...

I have a possible project from a customer who wants to light up a Star Trek Voyager model using Infra Red remote control. The problem I have is that he's planning on using 86 LEDs which, even if rated at 10mA each is 860mA which is too high for a Darlington Driver. The CHI035 18m2 high power...

Deleted thread - I hadn't coded the remote properly.

I have written code to perform various lighting effects using the 14M2 project board with IR reciever and sony remote from Picaxe. Most of it is working ok but there seems to be issues where the code isn't switching from one effect to another, so when I push the next button on the remote...

Hi all, I have set up an infra red sensor (LED020) with a 14M2 chip on the 14M project board AXE117. For info I'm running 5 LEDs off 2 pins through the darlington driver so one set lights up on button 1 of the remote and the other set lights up on button 2 of the remote. Buttons 6 and 7...

Hi all, I have a new project for a model plane to create some flashing wing lights. There is an existing 6v battery supply that my customer wishes to use onboard the plane which is already controlling various nav lights rather than adding extra weight with additional batteries. To drop the...

Hi all, I have another project I'm working on for a customer. He has an O gauge model railway and wants to light up the carriages when motion is detected. He previously bought a little motion detection microprocessor which is designed to run off a 3v coin cell but it's designed for N & OO...

I have a project I'm working on that requires a small PCB - ideally the size of the 08 proto board AXE021 or smaller but that can run 6 LEDs. Ideally I would use the 14m Project board AXE117 which is slightly too big or an 08 board with a darlington driver but that doesn't seem to be available...
