    stepper motor unipolare in full step

    Hi Nandino Your questions help me to learn as well. Legs means the actual physical metal leg and pins refer to the what it does like serial in, readadc etc. But on threads written by beginners they may write the wrong thing so we have to be careful. STEPPER I looked on google for your stepper...

    stepper motor unipolare in full step

    Also Nandino watch out faulty steppers. I recently bought ten micro steppers and five of them had no wire on one coil and some had coil resistance of 40 ohm (40R) not 20R, so I may have to increase the uln2003 driver voltage.

    stepper motor unipolare in full step

    Hi Nandino I'm a bit late for this thread but thought I'd add this anyway. I have a 28BYJ-48 uni-polar stepper to rotate my model crane project. I've put my crane post in the Robotics section, and attached my program file here also. I had delays so I added the suspend and resume commands so that...

    picaxe 08M2 reads 2.4ghz r.c. transmitter/receiver to control model tug LEDs

    Hi Volhout I also posted an R.C. project on the robot section which controls a plastic crane where I have fitted mini steppers, servo and linear motors and control it with the joysticks. It took me 6 months to do it, long time. Also I designed speed controllers for the propellers in...

    picaxe 08M2 reads 2.4ghz r.c. transmitter/receiver to control model tug LEDs

    Hi Volhout Thanks for adding your project. I see that our circuits are similar. I modified my project by adding a 12 volt change over relay because I discovered that new tug boat Towing Regulations state that when towing forward (Bow) extra lights on the front of the Masthead turn on (rear...

    operating a plastic model of a Atlas 5ton crane by a 2.4GHz radio control set

    I've put the photos on pdf so they post quicker. Maybe you've seen how small the stepper terminals are before.

    operating a plastic model of a Atlas 5ton crane by a 2.4GHz radio control set

    hi tmfkam I'll send two replys due to memory size. one shows the tx, rx connected to picaxe pcb. As you can see it's very prototypish and needs to be completed. The static yellow crane is what the supplier shows and mine has some small mods to accommodate the electrics.

    operating a plastic model of a Atlas 5ton crane by a 2.4GHz radio control set

    Oh the Steppers are bipolar 2 phase 4 wire drawing about 165 - 165mA and I didn't fit resistors. Yes I'll do that today and thanks for your reply.

    operating a plastic model of a Atlas 5ton crane by a 2.4GHz radio control set

    This circuit made on through hole stripboard houses 2 picaxe 18M2 controlling 4 L293D driving linear motors, steppers and a mini servo. More details are on each of the two programs attached along with a pdf the block diagram and circuit diagram. I have yet to finally finish, paint and semi-fit...

    radio control set to operate model boat propellers 08M2

    This post shows the final but not exactly as I wanted program to control the speed of a 12v 12 pole motor connected to a model tug boats propeller using a 2.4Ghz transmitter and receiver. I thought someone may have come up with a better program than mine. I wanted to move the joystick upwards...

    picaxe 08M2 reads 2.4ghz r.c. transmitter/receiver to control model tug LEDs

    My next 2 posts will also be on nano cad again then I'll use diptrace that I downloaded.

    picaxe 08M2 reads 2.4ghz r.c. transmitter/receiver to control model tug LEDs

    Yes I tried that but when I clicked plot it said this is only available on the professional version. So I'll try the diptrace you mentioned thanks very much.

    picaxe 08M2 reads 2.4ghz r.c. transmitter/receiver to control model tug LEDs

    I was looking for a free autocad lite when this nanocad 5 came up free so I used it but some features don't work. I've screen printed it but the text may be too small though. Thanks for replying.

    picaxe 08M2 reads 2.4ghz r.c. transmitter/receiver to control model tug LEDs

    Hi all This is my first post and I thought I'd send this fairly straight forward program. This reads the radio control from pretty much any make of transmitter, in this case it's a Planet T5. The receiver outputs 1 to 2mS pulses every 20mS (at about 4 volts) with 1.5mS being the centre...

    Code for mini bipolar steppers?

    Hi Jay Mike here from England, good afternoon. I just noticed your thread regarding mini steppers. I bought a plastic 1:32 model of a crane see photo. My full circuit looks at the pulses from a 2.4GHz R.C. receiver and makes the crane (via L293D drivers with 7 volts on pin 8) rotate, extend...

    CHI030 revb circuit diagram

    Hi Picaxe team I have bought some CHI030 rev b circuit boards and are a bit different to rev a could you please advise me as how to download the new circuit diagram to reflect CHI030B. many thanks.
