I've built several projects using 08M and servo motors and I've never run into this problem before. I put a sertxd command in the initailization portion of my program to verify that the chip is resetting. The chip and servo are on seperate regulated power supplies with large filter caps and a...

I've been wanting to build a unique thermometer but was unable to come up with a good idea. Then I was on YouTube one day and I came across the Geneva Mechanism. Perfect - it would let me control the position of the thermometer in accurate and stepped increments. Plus it's a cool little...

This clock uses 3 RC servos which are used to fan the cards out. To read it you simply read the highest showing card. The time displayed in the picture is 8:49. Since the picture was taken I glued circles, cut out of unused cards, back of cards showing, to the 3 uncovered centers.

It's a wooden clock with 2 gears. One for the minutes had and one for the hours. The gears are turned by levers wich are attache to a belt around some pulleys. The main pulley is turned by a rc servo. A picaxe 08M converts the 60hz coming from the wall to a one minute pulse. Another 08M...

A servo has an internal pot which turns as the motor turn and senses the motors position. The mechanical stop protects the pot from being turned beyond it's limits. Has anyone removed the mechanical stops and the pot. Then wire the pot back into the servo with extended wires? Seems to me that if...

I've been using PICAXE chips for about a year and I haven't run into this problem before. The circuit: 18X Picaxe Unused inputs tied low thru a resistor Other inputs going to push buttons and resistor. Other side of resistor goes to common. Other side of push button goes to +5. Reset is tied...

I have a couple of ideas I'm trying to sort through about making my own musical instruments which basically is a bunch of inputs that would produce a MIDI output - using an 18x and a modified version of hippy's program. I'm on a limited budget and I don't own any MIDI capatible instruments. I...

I want to build a mini Theremin using 2 GP2D12 distance sensors and a PICAXE. One sensor would control what note the PICAXE is outputing. The other sensor would control the volume. 2 questions: 1) Does any one have a circuit for controling the volume? The sensor outputs an analog voltage so I...

Can someone please advise me of the syntax for this command? The manual simply states: SERVO OFF. I'm using version 5.2.0 editor software.

Let me first say that this is not my first project using servos. I'm using seperate power supplies and capacitors across the power pins of the picaxe. I know that those are common problems and I don't want anyone wasting there time by responding with those common responses. I have a multiplexed...

I bought 2 28x chips. When I go to program them I get an unknown firmware error. When I check the firmware it comes up with: Firmware version A.2 (unknown firmware version 2) This is my first attempt at using a 28x - please help.

I built a fairlly complicated circuit using a 28x. My mistake is not knowing what commands were available, or not available, on port-c before doing so. I have 2 servos connected to port-c only to now realize that the servo command wont work on port-c. Has any one written code to control a...

PICAXE is great. I just finished my first project and I'm very pleased with the results. I've always wanted to build a bank that would display the number of coins and the value. Not only for each coin but a bank total as well. I have 4 optical sensors to detect the coins, 4 buttons to select...
