    Auto Switch off

    I am trying to make a battery disconnect when a time of inactivity is up. I was trying to find how I could have a 555 timer which has a default time of 3 minutes, but could be continually refreshed when a push button switch is pressed momentarily (taking trigger to low) and discharging timing...

    I am wanting to build batteries in a project to supply 9 volts. I looked at AA and PP9 batteries and then came across lithium version of PP9. Are the lithium batteries the best choice for getting 9 volts? Are there fire risks on battery discharging too low? Can I use a normal battery charger...

    Connector problem

    I bought some ribbon cable - 10 Way Unscreened Flat Ribbon Cable, 12.7 mm Width I did not realize how difficult it would be to solder to a 2.54mm 10 way header neatly. I have a 10 way male 2.54mm header on my board waiting to join with the cable. I looked around for ribbon connectors but found...

    Hall switch not producing low output

    I have been through 4 devices type A3213eua-t hall switches. Aail to go down to ov output, typically 0.04 volts. The datasheets show a 50k resistor going from 5v supply pin to the output pin. I used to get away with 10k resistors, however to get as near to 0 volts I had to use 100k resistors...

    HC-12 working supply

    I did not want to tack this onto another running HC-12 thread, not fair on the origins. Does anyone know a UK source of WORKING HC-12 devices. I bought 6 on Ebay, 3 from 2 suppliers and all dead? Don't know if anyone has same experience and knows trusted source. RS Components don't have. I...

    PCB Headers

    Sorry not directly a Picaxe question. I am finding a lot of 0.1mm PCB female headers (soldered pins) being floppy when pushed on the male part (pins) However, the ones fitted on the ends of servos and fans, being crimped pins and much firmer. Does anyone know of a cheap crimping tool in the...

    Avoiding relay use

    I while ago I saw a possible way to close switch contacts on a camera without using a relay. I am trying to short out switches to ground which are OSD settings on a camera. I found the menu modes would open and operate if I put 1k or 10k resistors across the pushbutton switches. I seem to...

    AXE027 problems

    I am getting problems finding an available port for my cable. It wants port 17 but that's being used. When I look at ports with the editor I see multiple entries on ports showing AXE027 but unavailable. I am probably to blame never plugging into the same USB. I am using Windows 7, anybody know...

    Arduino and Picaxe

    Can Arduino high/low outputs be put into Picaxe Pins to make Picaxe inputs high/low? Can one simply stick a 1k resistor between the two pins or isn't life that easy? Thanks

    V5.0 error

    Using version 5 editor. I am trying to clear the contents of an 18M2. I tried 2 IC's, but get this message? Anyone throw any light on it? thanks EDIT: Must be something I cannot see on board as just tried same with 08M2 and is okay. Does my error message point to anything obvious? EDIT...

    Remoting an IR receiver

    I have a Vishay IR receiver on a pcb being used with the Picaxe shop remote control, using Irin with Picaxe 20M2. I want to move the pcb to another location and have an arrangement to send Irout by wire to an IR emitter facing the Vishay device. This would end up as a local IR receiver that I...

    Has anyone had experience of this CNC engraver/drill/mill

    Still looking at milling or drilling PCB, and came accross this. One picture looks like rust on one guide bar. Just wondered how easy it would be to make a Picaxe controlled PCB drill. CURRENT EDIT: Anybody buying this...

    Chasing my tail - Toggle Switch

    I have a momentary switch that makes pinC.3 = 0 (normally held high) I am trying to make the action of a toggle/flip flop when the button gets pressed. When the button is pressed it is to make C.2 high or low depending on it's current state. However I cannot find a way round to make it a...

    Diptrace drilling positions

    Is there a way to import Diptrace pad hole positions into a Picaxe such that it could be converted into XY positions that a very basic XY pcb hole drilling machine could be put together? My idea being a scenario where the moving drill could be moved from left to right, and then back to left new...

    Ebay relays

    Anyone looking for nice, small, 5 volt relays. I bought some of these, waited a while to get tham, but excellent value for money. Not on commision, just thought I would do what others have done in past on bits I bought after finding out. On Ebay UK site...

    Mouse stops when using AXE027 lead

    I recently bought another wireless mouse as I thought it was faulty. Each time I used my AXE027 lead with the Editor5 my wireless mouse would stop working. Luckily each time I was able to plug in a USB mouse and not lose my work. I have removed and reinstalled my lead but it's still causing the...

    Muliple 7 segment display.

    I am doing a timer with a 14M2 and using a 4511 to drive 2 7 segment display LED'S. The idea to display 0:0 - 1:0 - 1:5 - 2:0 upto 5. To conserve Picaxe ports I went for a 4511 device where a combination of 4 ports switching generated digits 0-9 on 1 7 segment display. I then saw a circuit...

    1-5 minute time with 7 segment countdown display

    Does anyone have a link to a finished project for a 1-5 minute timer with 7 segment display countdown. Last time I did timer with simple LED's but looks a bit naff! Ideally, dare I say it, copy it for my own project. Don't want to reinvent the wheel if it's already done. Time not so accurate. I...
