Hi i am trying to generate a 12v signal from my picaxe circuit. I have bought some 2N7000 fets but cannot get it to switch when driven by the picaxe. could someone point help me with the interface circuit. thanks Matt

Hi I have been developing an LED driver circuit with a picaxe but have blown 2 up because the mosfet have gone south and supplied 13v to the out put pins which has caused amen moments to the picaxe. What would you recommend to protect the pins? Thanks matt

I am trying to simulate the following program and it works with the first interrupt but it seams not to reset after the first trigger. Am i missing something really obvious? 'fun pin output 'EN1 6 0 'EN2 7 1 'EN3 8 2 'EN4 10 4 'LAT 11 5 'PWM 9 3 'RED 12 6 'GRE 13 7 'BATV 1 2...

I am trying to turn on a picaxe using a single momentary button, then using that to set up modes functions for the project but the do a press hold to turn the circuit off. On the drawing SW1 and SW2 get shorted and make IN7 on the picaxe go high but also applys a voltage to Q1 via D1 there for...

Right i have created an LED cube see link. http://www.youtube.com/watch?v=xaV-g_0TDHA but now i want a practical use for a cool display, so i was thinking Clock. Now there is a clock chip for the serial LCD display and was wondering if this could be used and if anyone had? Thanks matt

hi i am trying to use a loop to output a number of Words (w0,w1,w2 etc) in order but don't want to repeat the code multiple times. i understand the us of masks and seen how its done before but cannot find the example again. could anyone help. What i want to do is cycle out1a and out1b with...

I have my pic project working really well BUT when i switch the 240V AC on off to the motor controller this causes the LCD to drop out. The LCD blanks the bottom line and black out the top line. this does not happen at all when the power to the motor drive is off. any thoughts!

I am using the serial chip to drive a 16x2 unit and had it working no problems. now i have mounted the board i yet a series of triangle in all the cells. is this indicative of a specific problem or am i going to have to chase down every connection. I have pull all the chips and checked them on...

I have been searching the net and speaking with some friends at work and they pointed/showed me an LED cube. There are some great videos on the net if you search google. i found this site which shows plans for a 5x5x5. Now i am planing to create one using a picaxe 28x2 but using the same led...

Hi, I am developing a integration circuit for my mill spindle controller. This will hopefully allow me to run it in a Auto Mode were it is turned on and off under CNC control or in a manual mode were it will run continuously. i am also implementing a tacho function and digital set speed...

hi, i am looking at creating a led driver circuit from an 08m using the pwm output as well giving battery output and status and mode changing function. has any one tried this and is there any designs on the inductors, caps and transistors to use. matt

Hi, i am trying to design a circuit to monitor each cell of a 2 cell pack using the series output through a regulator to power the picaxe monitor. does anyone have a simple scheme for the inputs side to feed to the ADC pins from each of the cells. I am unsure of what i need and how to isolate...

Hi, I am trying to install the Ax027 PICAXE USB cable. I am using a samsung R610 with home premium vista. I have downloaded the latest driver off your site and unzipped it into another folder. I insert the cable and allow the driver installation process to search for a driver. This goes to...
