Morning all, I've purchased an OLED for use with a PICAXE project (same project as a while ago with the avago mouse sensor). It's a cool little thing, only 52x36 and very small, but that is what I want. OLED: Brief: http://www.mouser.com/ds/2/295/ISC01P-32413.pdf More in-depth...

Hi all, I'm having trouble using the let pinsB command on my 28X2. When used, all the outputs on that port are go to about 1V. Good power supply, and chip + breadboard I've used with no issues a couple of times recently. I originally found the issue on the portC pins which were meant to be...

Hi all, This is for the same projects as a previous thread about PS/2 optical mouse. As before, I don't want to give away many details of the project because it might actually be valuable. I'd love to tell, you though, I'm quite pleased with an idea and we all know how that feels! I've got a...

Hi, I'm planning to use an Avago optical mouse sensor for something (think it might actually be valuable to keep this secret for once!). Problem is, it is IMPOSSIBLE to get hold of Avago mouse sensors in the UK. A few sites sell avago stuff, but all "non stock". By far the easiest way is to buy...

Hi all, I'm wanting to set up a camera trap using a laser and detector trip wire being "watched" by a PICAXE which in turn tells the camera to fire. It could probably be done without a PICAXE using some careful circuitry, but having the PICAXE just gives that extra degree of felxibility in the...

Hi, In the switches page 2 the breif description for this is: Is it really SPDT? Only reason I doubt is I've commonly come across switches like that which are just simple PTM or PTB (so, SPST) switches. It's used in the PIC buggy, and the datasheet for that uses that as simple PTM switches...

Hi, I'm trying to get a 40X1 (not great condition, but I think the required pins are working) to communicate with this digital potentiometer (50K version) via spi. I'm sure the digipot is powered up because I'm reading the expected 50K and 25K when so. I'm not having any success communicating...

Hi, The title is to make searching easier. My main question is regarding using a particular relay with a PICAXE, but I also have a general question about the states of I/O which is a far more useful piece of knowledge than specific information on a random component. I'll start with the title...

Hi there, first post in a while, and first post without "OT" in the title in an even longer while. First off, I'm at uni so time is scarce to say the least. With the Xmas hols coming up soon, I want to get this project planned and ready. Second; you might want to get a coffee/tea/stiff drink...

Hi there, This is a bit of a cop out of a post really because I'm going to link to another thread on another forum where another guy discribes the problem more thoroughly. Brief description though: A particular guitar effects pedal "Digitech Whammy 4" (WH4) is used to bend the pitch of the...

Hi there, Here's the situation in brief: Fixing a friend's iPod, accidentaly cut through an improtant cable, need to replace that cable (or the iPod £££), found the cable on eBay, asked the seller if it came with the "conductive tape" that is required to attach it, seller said "yes", so I...

Hi, this is nothing to do with PICAXE but I need help deciding between two laptops with slightly differing specs. I'm hoping this forum will be the kind of place that will have a few IT bods who I can ask via PM for advice. (PM because it doesn't seem fair to take up active forum space with...

Hi all, I wanted to make some code to generate a list of 30 random numbers between 1 and 30 with no repeats (just using PE as a helpful tool to do this). I couldn't work out how to do it without using 30 variables to store each number in so that I could check if a number had already been used...

Hi there, I'm currently modding a PS2 controller, by replacing the circuits with that of an old USB joystick. I'm basically taking all of the inputs from the PS2 controller and feeding them into appropriate inputs of the USB joystick's chip. The PS2 has two mini joysticks, and I want them to...

Hi again, This is another tank-related post. :eek::rolleyes: I've been trying to get the accelerometer to auto level the servo horn on a servo... Setup: Servo on it's side; accelerometer mounted on the horn parallel to earth; 28X2 reads the accel's value using i2c; PICAXE corrects the servos...

Hi, This is another tank-related post. I recently got that accelerometer to work with a lot of help from this forum. It uses i2c and so uses pins 11 & 13 on a 20X2. I also want to interface this compass module with the same 20X2. It is designed for "basic stamps" and specifically the...

Hi again, I am designing a headphone amplifier to fit inside my guitar and I would like not to add any more external controls. This is so I can plug my headphones (or speakers designed for a 3.5mm jack) straight into the guitar. I'd like to be able to power it on and off but just plugging in...

Hello again, this is another one in reference to a tank I'm making. It is basically a model tank, that has been converted to remote control using aircraft RC gear. I recently stripped it out though to start again, as I had added on so much stuff that it would be better to retry with all new...

I just tried to run a 28X2 at it's slowest speed using "setfreq k31". The editor came up with an error that was something along the lines of "setfreq k31" is not supported in this firmware mode. (I don't KNOW my 28X2's but I bought it almost as soon as it came out) The error message suggested...
