    Power Supply for Neat OLED

    That's a minor inconvenience about hspiout, but easy to get around as you show. However, I'm fairly certain it is reading the data wrong given the tests I've done. I have a feeling the data is going in alright, then for some reason it's being re-mapped in a weird way which is slowing it down...

    Power Supply for Neat OLED

    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...

    28X2 B.3 Firmware "let pinsX" strange behaviour.

    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...

    Mystery Stepper Motor

    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...

    Help !. Maths wizard needed !

    Hi, Had another though, which is that the information given by the angle "R" doesn't really help, it just gives the whole thing an orientation to a particular coordinate system. I've created a slightly simpler solution by rotating the coordinate system used, making R = (180 - C). srnet has a...

    Help !. Maths wizard needed !

    With two provisos I have a solution: 1: you can use your cosine table backwards to get arcos (possibly using a loop where it "searches" for the correct value). 2: you can read my writing! Hope it helps

    PS2 optical mouse sensor availability

    Using post 16 in this (which I KEEP referring to) and the manul's section on hspisetup, I came to the conclusiong of mode11. I changed my mind 3 times over the course of this though. My reasoning is: The clock idles high, so that's the 2nd and 4th traces from the top on Hippy's image. Hence...

    PS2 optical mouse sensor availability

    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...

    Using PICAXE pin as a switch

    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...

    techsupplies SEN050 Miniature Microswitch

    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...

    spi (not) interfacing with digipot

    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...

    Pin States

    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...

    MIDI, wireless, touch pad, guitar, PICAXE!

    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...

    OT Need some good problem finding minds!

    I bridged the gaps I'd made one by one. started with the 7805, then checked the outputs, everything was normal. When I plugged it in, the sensor LED stayed on and the other "mode LED's" flashed, as is symptomatic with the initial problem. Next, the 7905. Checked the pins, all was as before...

    OT Need some good problem finding minds!

    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...

    z-axis conductive tape (OT)

    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...

    Completely OT tech help

    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...

    Bit of fun while generating code

    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...

    ADC path switching

    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...
