I am trying to find a place locally (AUS/NZ) where I can purchase the AXE231 This is the 08M2 version of the SMD 08M board. Postage and time are generally the biggest issue for availability

I was wondering if anyone has some PCB designs for SMD 08M and 14M2. I know I can draw up my own in Diptrace, but it saves re-inventing the wheel. Sadly the AXE-231 is a little pricey for what I does and since I can etch my own... Many Thanks Marc

HI all and Technical I'm wondering when the 08M2 version of the AXE230 will be available, and if there is a supplier in Australia for them (new or old style AXE230. Unfortunately Wiltronics does not carry that unit. Many thanks Marc

Hi Folks. I am working on a small project using the DORJI DRA886 modules. I have the transmitter hooked up to a 28X2 with the simple code main: serout c.3, T2400_4, ("NNNNNN") pause 500 goto main With a scope I can see the square wave output. So it's very simple. I have a TTL RS-232...

Hi Folks. Over the past years my eyes have been getting worse, and I get tired of needing several sets of glasses around so I can do work. I investigated the cost of a decent microscope for work and the price was pretty horrific.. So I made my own for under $85 Parts - 7cm Car Reverser LCD...

Many thanks everyone for all of your advice. I realized in the end I was constructing the resistor array incorrectly and that the hall effect switches were not the one's I though they were (Damd SMD components) Anyway - here is the finished item and it works. I have worn it for testing several...

Hi Folks. Here is a picture of the shield. The round think at the end is a tiny earphone speaker so I can get feedback as a toned beep. After completing it will be given a coating of silicon or nail varnish to protect it. I apologise for formatting but with IE I cannot put in linefeeds :)

Hi Folks. I'm ok with digital but analogue sometimes gives me a headache. Can someone look at this and tell me where my thoughts went wrong I am using an AH1802 which is a hall effect switch. It has a ground, a Vcc (5v) and an output that is open collector so you need to put a 10K resistor...

What would be a good idea is the facility to tag posts as interesting so you can return to them later. Often I see a post that gives me a clue to solving an issue that I will work on in several months time. And the ability to tag into a personal favourites area would be great. Yes I know I can...

Hi Folks. It's late here and I have been working on this all day so please forgive and glaring assumptions. With a Picaxe 08M2 can one use the Serial In (pin c.5) for non programming serial What I want to do is to use a 08M2 and program it normally, then put it in a circuit with a USB to...

I know that one can download free board diesigns for the standard DIP Picaxe's but I was wondering if anyone has some basic layout boards for the SMD devices (08m2, 14m2, 18m2). My PCB Layout of choice is DIPTRACE.. Many thanks Dave

Hi Technical, Hippy,etc I have several small projects where it would be very useful to use serial communications as well as the servo commands at the same time, or atleast suspend the servo operations until the serial op's have finished. For example - retrieving servo movement commands from a...

Hi Folks I am planning to play around with some Murata Microblowers. If you have not heard of them they are tiny (and I do mean tiny) piezoelectric blowers. They work on a 15V PP Squarewave which swings between positive and negative at 25Khz. The current usage is very small but I may be...

Hi The AXE230 is a very nifty little board if smace is small. But at the moment is only uses the 08M Will there be an update to this to use the 08M2? I have a few small projects which this update would be perfect for. Dave

Hi Folks. I've run into a big problem with a project. Having testbedded some circuits on an 28X2 shield I now have made the circuit bowrd for it using an 14M2. I now realise that the 14M2 does not do SPI natively and I cannot get it to work using bit-bangin. The modules I am using are from...
