    Anyone know what this is?

    That would make sense, as there was actually a 2x16 LCD module in the same bin. Not sure how it would connect to the pins on the LCD, though... Or anything else about it for that matter. Thanks for the reply.

    Anyone know what this is?

    Found this little board in my loose box of Picaxe parts. I don't remember buying it, and have no idea what it is. The IC is a 16f84-04/P Anyone recognize him ? Richard

    Puddle of keys

    I was very impressed by the link to wilfs Sea of Keys idea for 128 keys on just one input. I had an idea for using it, but immediately realized it wouldn't work for me - the design allows the Picaxe to recognize only one key being pressed at one time. What I want to do is read the status of...

    Potentiometer choice

    Hi, what's the best range for a pot to use with ADC on an 08M? I'm using a 10k that I had lying around, and I only seem to get a range from about 115 to 170

    Rotary Decoder

    Hi everyone. I'm using a modified version of the code that *genairco* posted to try to read a rotary encoder. The code I'm using is : <BLOCKQUOTE><font size=1 face=arial>quote:<hr height=1 noshade> start: 'establish a known start state from which a known logical pattern may be expected 'from...

    reading a Picaxe

    Being the knuckle-dragging goober that I am, I've managed to overwrite the PC file containing a Picaxe program I've been working on. The program is in a chip, and working fine as far as it goes, but a) I'm not quite finished tweaking it, and b) I'm going to want more than one. Is there any...

    Picaxe takes flight.....

    Thanks for the help from everyone over the last couple of weeks, my first prototype picaxe powered flight simulator instruments operated last night :-) Two servos driven by an 18X operate the artificial horizon, and a stepper motor driven by an 08M operates the heading indicator. (The flight...

    serin... no answer?

    Is there any way for a picaxe to wait a short time for a serin stream, and if it doesn't get it, go back to what it was doing? I'm thinking of... serout (&quot;ready&quot;) serin #b1 pause 100 if #b1 &lt;&gt; &quot;&quot; then something something else: Is there any way to do this, or does a...

    T-shirt transfers

    Has anyone ever tried using the T-shirt transfer material to make resist masks for etching PCB's? I've tried using the trick of ironing laser-printed masks onto the copper and then washing off the paper in hot water, but I've had, shall we say, &quot;less than consistent&quot; results, so I...

    Someone explain the math, please?

    If I say &quot;for b0 = 1 to 260&quot; the Picaxe goes into an endless loop. Why? I undertand that b0 cannot be more than 256, but I don't understand why &quot;b0 = 260&quot; doesn't turn into &quot;b0 = 4&quot; Thanks, Richard

    Sharing a Comm port

    Hi - If I connect the serial port of my PC to the serial in, serial out and ground of more than one picaxe, and then use &quot;serin 1, N2400, &quot;A&quot;, #b0&quot; on one picaxe and &quot;serin 1, N2400, &quot;B&quot;, #b0&quot; on another, etc, will that give rise to any problems? As I...

    "Virtual Oscilloscope" probes

    Hi - there's a number of good PC based &quot;virtual oscilloscopes&quot; available for download that let you use your PC's sound card as an input. You can even have a two channel O'scope if you have a stereo mic inout. But... I know that if I send Picaxe output levelsignals into the mic input...

    Chatting to the Picaxe

    While getting acquainted with the Picaxe's there were several occasions when I've wanted to send / receive between the PC and the Picaxe with a little more control than just by using the F8 terminal option in the programming editor, but didn't want to write a specific application just for the...
