Hi guys, I'm trying to make a 6 button PICAXE program that will detect the order that these 6 buttons are pressed in. Specifically, I'd like to have 6 7-segment LED's indicate the order numerically. Ie 1,3,5,2,4,6 etc. Timing is not really important. The buttons will not be pressed...

Hi folks, I'm trying to set up an encoded signal from a transmitter using the above chip. It doesn't have a TE line, it simply wakes up when there is an active data line. On the sample circuit, they ground unused data pins, but on the switched pin, there is a 200k resister to ground, and a...

Hi folks, Is there a "typical" way to upload a program to an SMD PICAXE chip? The application requires a minimal foot print so point-to-point wiring is my ultimate goal. Is there a temporary breakout board to use? A chip adapter? Thanks Nitrous

Hi folks, I'm designing a tag module (size is a limiting factor) that will wirelessly identify when a cap is removed from a marker. I have an RF transmitter lined up that is ASK modulated, 433mhz that will connect to an 08M chip. I imagine a program running that will send a unique ID to the...

No, I'd call that a coil. This is more typical of a cheap quartz clock movement. The above shows the "poles" of the magnet that wrap around the rotor.

Hi guys, I'm trying to generate an alternating current signal to drive a quartz clock stepper motor. There is only one coil. I believe the drive relies on alternating the poles by cycling the drive voltage. These are not expensive dual coil movements. Space is at a premium. I would like to...

Hi folks, I've looked around the forums but not found anything that is able to answer this question. Is there an easy ( if not easy, at least do-able ) way to convert a printer with USB and IrDA ports to wireless RF capabilities? The device is an mPrint MW-100 Brother Thermal Printer. The...

Hi folks, What kind of detection range is possible with a magnetometer? I realize magnet (detecting a neodymium magnet) strength will play a big factor, but what sort of range might one expect with a coin size N42 magnet? Would a three axis device be superior to a 2 or even single axis device...

Hi guys, I am trying to design a project that will read one of 6 NO switches to detect the position of a six sided cube. So, if the die face is showing a 4, a switch will close to indicate this. I have a 4-direction tilt switch and would add a couple of single direction tilt switches in a...

Hi folks, Has anyone created a DIY servo controller (1 or more servos) that can be controlled from a stand-alone crontroller board which records the servo signals for playback? The servos would be hobby grade and the amount of memory sufficient for 4 or 5 minutes of control. Any ideas? Any...
