Hello Everyone, I've started using the Mumble VoIP service recently, usually for talking to friends while messing about on the computer. Because of my setup I'm practically forced to use push to speak. The trouble is most keys are either printing or have some other function, so finding a usable...

I think all the schematic designs are done! I've gone all out with the specs! 16Bit data and 32Bit address (4GB space as 256 32MB pages!!!:D ) Theoretically a 64+MHz clock. The instruction set is laid out in a programming language style, space expensive but much more user friendly! It could (I...

You've had a nice rest from me but now I'm back! I've been working been working on a sine wave generator using a R-2R DAC, not brilliant I know, but good enough for this project. I'm running this on a 20M at 8MHz but it's not fast enough and the output is just a low frequency sine and a load of...

Hello again, Today I come hunting some information. I went to maplin today and for £4 got a display lucky bag. I'm fine with the LED displays but I also got a VFD and a few COG displays. The VFD is a Futaba 13-BT-77. The internet has noting to say about it so I wondered if anyone here knew or...

I'm back again to annoy you all with another question, this time it's about VGA with a PICAXE. Is it possible, and is there any existing code, to produce a VGA (VGA connector, it doesn't have to be 640 x 480) output with a PICAXE? Alternately is there a chip on the market that will let me do...

Hello again, Today I am looking for a RAM chip for my upcoming TTL computer. It will be for program storage. I am looking for a chip that I can program with a PICAXE, probably a 18M. I want to use a PICAXE to interface the RAM to save me the laborious task of hand programming. I've been having...

Hello, I know this isn't a very PICAXE related project but it may be involving a PICAXE later... What I want to do is have a relay to switch on and off at no more than 10Hz. I understand there is a way to do it by charging and discharging a capacitor but all of my attempts so far have been...

I have been looking forward to using my etching equip for a while now but before I go and waste a whole batch. Anyway on with my board: The board I have designed is my own implementation of the AXE029 breadboard adaptor which is compatible with the 08,14, and 20 chips. I use the 08M allot so...

I was wondering what circuit I would need to send serial data between two PICAXE chips? I see no mention of it in the manuals. Basically I wish to use an 08M as a sort of shift register connected to an 28X1. Also is it possible to use the Serial in/out pins and the SERTXD/RXD commands. Would I...

Hi Guys, As always, I have grand plans but not all the knowage to complete them. So my question today is... How powerful would a motor need to be to move a wooden go-cart (with a person on it) around? It is to be 2 wheel drive, with both an onboard arcade joystick to controll the movment when it...

I have recently dismantled a computer and got a Maxtor 40GB HDD out of it. The spindle motor in the middle has 4 pins coming from the left they are labelled as this from top to bottom; MTR-C, MTR-B, MTR-A, CT. I'm guessing that's coil 3, 2, 1, and ground. When the HDD is plugged in to a power...

I know multiplexing is possible with the PICAXE system but is charlieplexing or even GuGaplexing possible? Originally I was going to make a 6X4 Matrix for a BCD binary clock but having heard of these methods I wondered if I could make it bigger?

I am having problems with the programming editor crashing on boot after clicking OK on the options screen even without changing any settings. I need to put it in 08M mode but it keeps locking up.:confused: Any help?

I have decided to buy the picaxe development kit, with the serial cable, and wish to use it with both PCs with serial ports only and also my laptop with only USB ports. Looking at the extreme price of £10 I decided to look elsewhere and came across this little number from eBay for 1/10th of the...
