Hi, I just received one of these breakout boards from Sparkfun and hope to power my picaxe projects from my blackberry charger: https://www.sparkfun.com/products/9614 I could have sworn a little while ago that I found a thread here that covers using these, but now I can't seem to find it...

Hi, Is it possible to use a simple voltage divider to get 4.8v from a 12v supply, rather than using a 7805? I have attached a simple circuit diagram without capacitors for clarity. Many thanks, DDJ

Thanks for the replies. I can't find a schematic for the AXE049 either which is why I had to ask. All I have is the image below (ripped from AXE049 manual). Maybe Technical can shed some light on this???

Hi, I have an AXE049 board that I programmed to communicate with my AXE133Y OLED module. I now want to be able to read the value from an A1302 linear hall effect sensor using the AXE049 but can't figure out how to connect the sensor to the board. Can anyone help? Thanks, DDJ :confused:

Hi, Not sure where to post this so starting out here. I have been reading the forum on a tablet computer browser (not the App which requires a separate thread) for the last few weeks and have noticed that some of the buttons are a bit small for easy use with fingers as opposed to a mouse...

Hi, Does anyone know a low price UK (preferably) supplier for UGN3503 or similar Ratiometric Hall Effect Sensors? I need 8. I've tried Farnell and Rapid as well as ebay with no success. Many thanks, DDJ

More Efficient Lighting Strategy? Apologies if this is old news but I haven't seen it documented elsewhere. Also, if I am missing something obvious here by proposing this approach please explain why so that I don't waste any more time on it! In thinking about the time available to light each...

Hi, I'm drawing up plans for an LED cube. I'm going to start at 3*3*3 single colour and progress from there. My aim is to reach 8*8*8 with RGB LEDs. I'm going to multiplex the LEDs and need to expand the Picaxe output ports through the use of one or more shift drivers (depending ultimately on...

Well, my daughter's water spraying alarm clock got nowhere - not helped by me fritzing the pump the day before the competition! My next project will be an LED cube. I'll be starting small - 3*3*3 single colour to get my eye in, but ultimately I'd like to do a 7*7*7 (or maybe 9*9*9) RGB like...

Hi, I have an AXE049 board and the Picaxe shop link here says it has: "Solder pads to allow a piezo and servo/serial LCD to be added". In the attached diagram (ripped from the AXE049 pdf - sorry!) I think I need to connect my AXE133Y to the solder points in the circled area (0v, Out7, V+)...

Hi all, Back after an absence of a few months. I'm still building my alarm clock which sprays water, but time is now critical so all help appreciated. The first competition is less than 2 weeks away - would be awesome if the Picaxe could take centre stage! I have an AXE133Y display which...

Did anyone manage to order one yesterday? I hadn't realised it was the launch date so I missed it :( However I have registered for one and hope to get it soon - then the interfacing can begin!

I have an AXE133 LCD display (which isn;t working but I will follow the hints here to see if I can make it go) . I do however have another question that hopefully someone can help me with: I want to connect my lcd to a DS1307 clock (I didn't buy the AXE LCD with attached clock) and was...

Stripboard Design After a long absence, during which time I haven't progressed this at all, could you review my stripboard design? This is the agreed circuit from earlier in this thread: This should be the same circuit represented as a stripboard using PEBBLE: This is the PEBBLE save...
