    Having fun playing with new Hall effect chips

    Well I like to pass on fun devices when I run across them, so I thought I would pass on two Hall effect items I just got off E-bay. I had heard and read about Hall effect devices before but never really had a need to actually try them, so it was a first for me to play with. These are both very...

    Afforable rotory optical encoder found

    I've spent several months looking for nice industrial grade quality rotory optical encoders on E-bay but just not found anything at nice hobby prices avalible. Finally I stumbled upon B&G micro and they seemed to have a nice price on one without a lot of details provided. I went ahead and...

    Bargain found for logic level power MOSFET

    I'm sure many of you are aware of how useful logic level power N channel MOSFET transistors are for allowing a Picaxe to switch high power loads with minimum hassle. I found a nice buy on E-bay on ten 60 volt 50 amp devices and thought I would pass it along for those of you in the USA. It works...

    More to life then just Picaxe fun

    Ran across the below video yesterday and had a lot of fun researching about them. Not real useful for anything practical as it drains the battery pretty quickly being a almost dead short across the battery. However it should be fun to try and impress my grand daughter with them. I found a ton of...

    Interesting new USB Picaxe modules seen

    Ran across these tonight on E-bay. Seller appears to be very new to E-bay and I've had no contact other then reading the listings.

    OK how does it work and can a Picaxe do it?

    Check out this video I saw on another site. Can we figure out how it works and make a Picaxe do it? Lefty

    Nuts & Bolts mag to host Pixaxe primer

    Nuts & Volts mag to host Pixaxe primer Just received Dec. addition of Nuts and Volts and they are starting an every other month Picaxe Primer section by Ron Hackett. While N&V has had many Picaxe articles in the past it's nice to see a regular installment start and I'm sure it will bring...

    For us oldtimer geeks!

    How cool is this? Had to share this item, not to encourage purchase but just so we can gander together. We've come a long way in this hobby Lefty

    5vdc latching relays @ 40 cents each!

    We probably don't want to see a bunch of commercial offerings on this forum but I thought this deal too good to not let those interested know about. I've no attachment to seller other then having bought 10 of them recently. These are 5 volt, single coil, 2 amp DPDT contacts, latching relays...

    Floating point support chip

    I was checking out the SparkFun web site and ran across the uM-FPU V3.1 Floating Point Coprocessor chip. I noticed they have a free IDE software that will generate Picaxe interface code. So has anyone actually used this V3 chip? It sure seems to have a lot of features in addition to the FP...

    New 28X1 arrived, works great !

    Well after waiting it seems forever my new 28X1 arrived Friday. I cobbled together a small radio shack perf board with just a basic picaxe passive serial interface and reset switch, but did add a socket mounted 16mhz resonator that came with the 28x1 and a 16 mhz 4 pin oscillator chip, with a...

    setfreq for new 28X1

    In anticipation of my 28X1 arriving (soon I hope!) I would like a little help on understanding external resonator Vs the Setfreq command. The new manual2 states that the yet to be released X2 uses a 4X PLL so that external resonators need to be 4 times slower then that actual clock speed...

    ADC10 - PWM question

    Hi Group; Just acquired a picaxe stack 28X kit this week and got it assembled and going yesterday. I'm very impressed with the whole picaxe system and know I'm going to have a blast. I've been exploring the features and learning the software. One quick experiment I did was to test out the ADC...
