    Deal on RFDI

    I was in Radio Shack today in the USA just blowing some time. I went to the parts bin and found on clearance a Parallax RFDI serial board and it has 2 cards also. for $8.95 including Tax. This item is $40 on the web site some I bought it. should be fun. Steve

    I2C wiring

    So I am looking at the schematic in the FAQ for the I2C and find resistors with values of 4k7. Can I assume this is equal to 4.7k ohms? Steve

    What seem to be a silly question.

    OK I have none of the newer Picaxes and was looking at the X models and it seems that none of them have I2C master capabilities. Am I missing something or is this the case. I have read the I2C tutorial and also the FAQ for the 18X 28X and 40X Steve

    Large project simple question

    OK. I have looked at most of the data and am somewhat confused. It looks like the smallest Picaxe I can use seems to be the 20X2. But I have not explained my needs. So here goes. The project will need 8 controllers with a minimum of 8 outputs each. However and this is what throws the wrench into...

    Making a controlable switch

    I have a Rebel XTI that I wish to make an Intervalometer for with an 08M. Try as i might I cannot get a solid state relay (that I know works with a 120volt christmas light string and 5Volts as control input) to work. I think it requires a minimum voltage push on the out put lines to turn on. So...

    Resonator

    OK I feel silly asking such an inane question but here goes. I bought a few picaxes a while ago and then life got in the way and I could not play with them. Now it seem I have some time but all I can find are resonators that seem to be 16 mhz. The markings on them are. ZTT 16.0MX are these the...

    Multiple picaxes in one robot.

    Many months ago I remember reading about a robot that used several micro controllers networked together. Each had a small task to do except for one of them that took all the data gathered by the others and crunched the numbers, figured out what to do and sent out the commands to all the others...

    TV romote for an IR controller

    I have researched the Sony remotes and have found what I think is the codes for the input I will receive on my picaxe. However I am not sure. If anyone has tried this I would like to ask if the button and codes are like this Button 1,2,3,4,5,6,7,8,9,0 code 0,1,2,3,4,5,6,7,8,9 This is the way I...

    real world app

    OK I finally figured out a real world application of my own to try. I am a fellow of many hobbies. electronics being only a small part. I also woodwork some and have a large collection oftools in my shop. Sometime I find it hard to get to some of them like my dust collector and air compressor...

    controlling voltage higher than 5V

    I am strong in digital but somewhat lacking in analog. So I have been trying to figure out how to control higher voltages such as when one needs to control a DC motor with PWM but it requires a drive voltage of 12 or 18 volts. I understand the design of H-bridges but can't figure how to run them...

    I2C

    I would love to see I2C on the 8 pin picaxe. One could use each for a different section of a robot control. each as a sub processor
