    Power recommendation question (12VDC)

    Just a quick follow up to my current draw post. Here is the rig in 'action'. No PICAXE control here. I am prototyping the rig with simple 3VDC motors until I get things coded 'somewhat' correctly, then scale up.

    Power recommendation question (12VDC)

    I am building an outdoor robot that has two 12/24VDC motors (see pic). When completed the robot will wander around the back yard to do the evil bidding of my choosing. The motors are geared down pretty good and very very strong. Forward motion is a slow ~33 feet/minute; which is about the...

    Unexplained Variable

    The memory map I was referring to is attached. I use the excellent westaust55 one as well. This one is more 'bare bones' for understanding bytes and word memory. I got this chart from the forum. I did not create it, but thanks to whoever did!

    40x2 minimum circuit

    Behold... I have a 40x2 that was given to me (lucky me!!!) Looking at the documentation of my AXE091 Dev Board I see the min circuit for 28 pin devices, but not the 40x2. A quick look seems to suggest they should be different due to the external resonator. Am I missing something? Is there...

    Analog Clock turned Voltmeter

    I felt sorry for all the clocks that were left out as more and more people turn voltmeters into clocks. This is my revenge:

    PICAXE with Electric Imp Their tag line is "WiFi to everything" and that sounds interesting (and cheap). Has anybody experimented with the Electric Imp and a PICAXE?

    Senior Member

    I just noticed on my profile that I have the honor of being a Senior Member. I'm honored and plan to uphold all the responsibilities of the title, but is this just because I have asked enough stupid questions (such as this one) to get my post count past a certain number?

    DS1307 RTC and 24LC156 EERPOM Work Separately but not together

    Using the LKM1638 discussed here with a: - PICAXE 18M2 - DS1307 RTC - 24LC156 EERPOM The objective is to display the time of day (from the 1307 RTC) on the LEFT four 7 segments and display a four letter words from the 24LC156 EERPOM on the RIGHT four segments. Separately every thing works...

    Fixed amplitude PWM 14M2

    As mentioned, the P-P voltage should stay the same. Video shown below is from the PWM routine of: pwmout C.2,99,400 'start PWM on Port C Pin 2 @ 100% main: for w1 = 0 to 400 ' pwmduty needs a (W)ord var, not a (B)yte var pwmduty C.2, w1 'adjust PWM Duty from 0% to 100% pause 2 next w1...

    DealExtreme 7 Segment (plus) Display

    Project update from the OP: Early status. Short vid below. I have time displayed on the LEFT segments. One of >1,000 four letter words on the RIGHT segments. I am storing the >1,000 four letter words in a 24LC256 EEPROM.

    DealExtreme 7 Segment (plus) Display

    Thanks, westy. Making progress.... See attached pic that is "suppose" to read PICAXE. I am having difficultly controlling the "C". I figured out how to remove the decimal point in your routine, but it appears something else is going on. For some reason I can control every segment reliably...

    ID this device: ELMWOOD 99/30 3100-1 L158

    I hate to do this because it always ends with a google page slap. That said, I have googled away and still can't find a datasheet. I throw myself on the mercy of the forum and all it's friendly engineering snarkiness. :eek: I unscrewed four of these from a BIG heat sink. The original product...

    ZIF socket multi chip programmer. Not a dev board

    Lately I have been programming several PICAXEs for people. It is a pain to insert and remove them from my AXE091 dev board just to program them. Plus, I often have a PICAXE already pushed into the dev board. Removing it with all the surrounding wires is not easy and depending on the state of...

    Another answer to the "what to do with my old hard drive" question

    How about.... Use it as a PICAXE input device. My simple proof of concept with code, etc here: Long term, would the PICAXE complain about seeing a negative 500mV on the ADC input?

    If I cracked open any commercially available product, would I find a PICAXE

    A little off topic from the typical technical discussions, but this is a PICAXE curiosity of mine none the less.... Is there anything that a typically consumer would buy (toy, microwave, remote, etc.) that has a PICAXE in it? I would think the answer would be "no" because it is aimed at the...
