    Diy Ups

    Hello again, I am looking at building a UPS to keep the network and a server running during "short" power failures, and ofcause safe shutdown, alarms, temperature monitoring, all the stuff that you dont get from a black box marked "UPS" :) My last UPS died out after 3 years service so I have...

    I2C/1wire bus buffer

    I am building a 'small' network of picaxes and 1-wire sensors. The I2C parts are controlled with a 74HC4051 to give me 4 lines (4pins unused) that are seperated, both to keep noise in control, but also to avoid address collisions. The 1-wire part is connected to 4 pins on the picaxe, so they...

    Cheap oscilloscope, logic probe and ttl serial

    Hope this is not too off-topic... If anyone is looking for a (very) basic scope or logic probe, the pickit2 programmer may be worth a look. Its a USB programmer for PICs (ie. not the picaxe ones, or you loose the bootloader). But it also contains a 3ch logic probe (2channels with pullup), a...

    Garage parking sensor

    Mounted on the back of a garage to help indicate when the car is far enough (and yet not hit the wall). -Ofcause drivers still have to look themselves, not rely on the thingy always working. SYMBOL RANGE = 0 'Maxsonar EZ (Dont remember which of them, one with a narrow beam is probaly best)...

    hsersetup with shared scratchpad

    Im looking for some advise on how to handle shared scratchpad between program data and hardware serial. First a copy from the manual ... I would like to use the scratchpad for some temporary data, but also use hardware serial, what would be the best way of doing that ? 1: Run the hserserup...

    Radio rules

    To follow up on the other radio thread about aus. What rules are other countries using ? Denmark for starters is very restrictive for non-license holder and custom equipment (Sadly finished radio modules is custom)... These are the limits AFAIK 100mW at 2.4ghz with spread spectrum (ZigBee...

    Problem with VDrive2

    With all the threads about 64MB+ space on the PICAXE, I ordered a vdrive to try it out, but the documentation is poor at best :/ I have hooked up the vdrive, but it just flashes red/green alternating for 2secsm pause, repeat, in the manual this is done "until monitor connects". The picaxe is...

    Generate short circuit

    Hi, After spending some time with different platforms, I have a project where PICAXE seems a good solution. T-hansen in Denmark sells an "electronic launch system" for fireworks, which I want to make a better control box for (instead of the somewhat unreliable infrared one they provide) for...

    Compile a "binary" ?

    In the future will it be possible to compile just a binary from the bas file ? So that you can send this binary to someone else that should not see the code, and they can program the picaxe from this ?

    Prototype boards

    I am looking for some decent prototype boards for mostly 14-m and 20-m, but where to look besides the picaxe show, which has a very limited selection ? I would like (not everything has to be present on a surgestion) Battery plug DC adapter plug (with 7805) Room for terminals on some/all...

    Boosting an analog signal

    I have a US module, that I would like to read using readADC, but its output is much too little for picaxe to detect changes precise enough. For the range I need it will output 0.2 - 0.5V, so I need to boost this x10, but also make sure picaxe dont get fried, since the sensor can (and will at...

    PICAXE controlled window blinds

    Anyone know of projects controlling window blinds ? I dont know much about advantages in different motor solutions, my understanding is in () below. Servo(Will turn to a position, and offer readback of position) stepper(must be pulsed to move, very acurate) regular (apply power and it runs...

    Range detector

    Any advise as to which range finder modules a picaxe can interface with directly ? Maybe some of the cheap ones from acroname ? http://www.acroname.com/robotics/parts/c_Sensors.html I will mount it in a static place and it will monitor distances up to 2meters, minimum is not so important but...

    Simplelan projects

    So what projects are on their way ? :) I have made a Ethernet controlled relay box,so I can control all the routers and stuff in the closet, and a led controller on its way. Other ideas. Temperature readings ofcause Remote LCD? fairly useless probaly Serial2Ethernet maybe I was thinking of...

    Relay causes picaxe to reset

    Hi, I have a picaxe (28x1) connected to a relay board and simplelan. When the relays dont have any load it can turn on and off all relays without problems. When I connect a 20Watt lamp on one of the relays, the picaxe very often resets when it turns that relay on/off. I didnt make the rely...

    SerIn with breadboard adapter ?

    Chip: 28X1 Editor: 5.1.4 Firmware: A.1 Supply: Regulated 4.5V Should serin work with the breadboard adapter? The resistor circuit looks the same, except for the added 180R on the tx line ? I have connected tx to the resistor, then to input 0. Out1 connected to output 0 (And jumper is set to...

    serrxd problems - 28X1 internal resonator

    I am trying to readin 6bytes using serrxd with a qualifyer. It is almost working, but I have to send the data 2 times before anything happens, and the last few bits are wrong. I am using AiTerm to send the data "raw". %01110111 %11111111 %00000000 %11111111 %00000000 %11111111...

    #input on 14-M

    Not sure if this is a bug, or just me not using inputs like I should, in the simulator the code below works fine with the 5input buttons, but on the real picaxe (Tried 3chips) inputs 0,1,2 is always 0. I tried tieing all inputs directly to supply (5Vdc), and only input 3 and 4 becomes 1. Seems...

    Help with %masking

    I have 7bytes where I need to pick a few bits from each and combine to less bytes, is this possible with the %masking ? Right now I am using if, but the compiler says im 50bytes over limit :/ The 7 bytes are like this %01000100 I need to make 2 new bytes with the two ones, bit2 and 6 I think...
