    Buzzer game

    Hi all, I've got a new task. I'm to design a controller for a quiz game. You know have four tables and every one of em has a buzzer, who ever presses the button first gets the chance to answer. The thing initially in my mind was to write a comparator, like: if input1 =1 & input 2 to 5 = 0...

    PICAXE & Roland sp404 MIDI controller

    Hey Everyone, I was wondering if anyone's ever dealt with a ROLAND SP-404 MIDI sampler. A friend has asked me to build a remote control for him so that he can play his sound effects without standing next to his sampler. The device has a MIDI IN. so i'm assuming that there's a way to...

    MP3 Player Hack

    Hey all, I have a difficult one (I think). I want to hack into an MP3 player using its switch interface to control it. basically i got a normal MP3 player from an electronics store to open up and see if i can do something with it. It runs of a 1.5V AAA batt. after opening it and checking...

    9V charger circuit

    Hey all, Here's the scenario: I am making a clock with a 20X4 LCD module. I thought that i'd use a 9V rechargeable batt and use a LM7805 to drop down and regulate the voltage. Considering the LCD will be running all the time and the Backlight will be on as well the batteries are bound to run...

    Infra IN issue

    Hey guys, I wanted to make an Ir reciever board, using the infrain command. But although the circuit is fine, the syntax is fine, i cant get any data out on to the terminal. My basic test code on the transmitter is: ; Transmitter. 08M. IR LED on out0 (infraout pin) main: for b1 = 1 to 10...

    1.5V to 4.5V charger

    A Very stupid question, but my friend once said that there's no such thing as a stupid question. so here it is: I want to use a garden solar light (1.5V) to charge a 4.5V batt pack for my 08M. Ultimately the 08M is gonna be in this garden light and i dont want to go over and change the batt...

    POV Clock

    Hi All, Has anyone tried making a POV clock with a picaxe? I couldnt find any info about it on the forum, but then again i may have not searched that well. I got the idea from this: http://au.youtube.com/watch?v=no2_M_b059g I cant figure out how the data would be displayed with the rotation...

    Picaxe rival

    Hi All, I was just searching on the www and found a micro company called Basic Micro: http://www.basicmicro.com They are selling their micro with pretty much the same instruction set as our PICAXE but with more pins and feathres... i think. It seems like another parallex basic stamp thing...

    Picaxe Project Ideas for Physics

    Hi, My Physics Department has allowed me to do a research sort of project but only if i come up with a good research question. They are not really that fussy abt it being too deep a research question. I was wondering if i could do something with the PICAXE, u know like some robot. I came up...

    12V readout

    Hi, I am trying to read a ~12V DC supply and observe the voltage drop when a motor is turned on. I wanted to see if i can read the voltage from a lipo battary pack on my RC CAR and if the voltage drops too low i can switch to the secondary battary. Thought it be a good idea for a longer run...

    TTL Serial data

    Hi, i want to send some strings of TTL Level serial data from one micro to 2 others on a single line. I was given a suggestion that i should use an opamp as a buffer. but im not sure if thats the best option. the string i want to send is simple" Hello, This is micro one". I just wanna see how...

    Serial data

    Hi all, Im sort of new to Picaxe. I was trying to send some serial data from my 28X to the coms port. What I was trying to achieve was to send a string to ask for a number. That number would then be used as a counter limit to flash an LED. I couldnt get it running but i also noticed that on my...
