Hi, my goal is to send a text message from a webpage or server to a picaxe connected to a router (and internet) the picaxe would then just display it on a LCD display Any idea regarding where to start ? is there another solution except of the expensive Picaxe net ?

Hello. I would like to be able to run a command (pulsout) on absence of power supply (at the moment of dis-connecting power) it can have some delay, and I don't care at what voltage it triggers, i just need a non-accurate way to send a pulse before there is no more power at all. The problem...

Hello, I'd like to know, For example lets take the 08M. is the command time slower than the parallel PIC that 08M was before loading the picaxe firmware ? What i'm worried about is the delay between detecting an interrupt to triggering a pulsout. Thanks !

Hi, I have an input pin pulled high, with an interrupt to detect its low state. I have two ways of triggering the input - a button that shorts that leg to ground, and a camera trigger remote that is connected exactly to the 2 pins of the button, so they both should do the same. the thing is...

Hi I am looking for a way to setup 3 potentiometers, so one of them is used as the "power dial" one of them set the maximum value, and one the minimum. the thing is, that it is not a voltage divider. which means the ohm value is critical all the way. (not just the proportional 'travel' of the...

Hi. I am trying to program a picaxe that will: output A: charge a capacitor to a given voltage, with feedback from ADC 1 input. output B: pulse every X seconds that will make the capacitor discharge. X is set by a pot on ADC 2. i need a software that will: 1- send the timing pulses to...

Hi, i need a picaxe to control two FETs (IRF3205) for an DC-to-AC converter. currently i use the TL494 which is a PWM controller. i need a 25% duty cycle for each port, so the sequence will be: port A 25%, NONE 25%, port B 25%, NONE 25%,,,, and repeat. frequency needs to be about 10 KHZ is a...

Hello I have a stepper motor that is rated 0.7 Ohm per phase, and 4A per phase. The L298 datasheet says that resistors between pins 1 to ground and 15 to ground are used to limit the current of the load, but it doesn't show anywhere how to calculate the needed resistance. I am running on 24v...

ok, that's not directly picaxe related, but as i've read very smart comments before, i guess someone could help... I need to connect a USB device to a PC host, with long range (200-500m LOS) found the "cables unlimited" thing, and other solutions from Belkin, but they are just 10m range. i've...

I've seen the HSEROUT can be used at 115200 speed, i just want to make sure it is achievable on 20X2 chip, and ask if someone had any stability issues due to increased speed. by the way, the command structure make it possible to run the chip at 8Mhz but still use the 115200 serial, right ?

hi, im gonna have a 20X2 receiving data each 4 seconds. it will be permanently in serin mode, get the data, send to LCD, and go to serin again.... i need an alarm for notifying when the 20x2 doesn't get the data anymore. i thought of putting a 08M along with it: after the 20x2 get the right...

well, the system is working so: a 08M reads the voltage of a 12v battery through 50k voltage divider. it is also fed with well decoupled 7805 off the same 12v battery. it works great with debug. steady reading. the same 12v batt is feeding a switching dc-dc converter that outputs 5v to feed a...

I've came across this: http://www.narobo.com/products/DroneCell/DroneCell.html (scroll down for datasheets) it says it works with any UART TTL microprocessor. basically my requirement is a device that will read GPS position and will send it as a text message. this will happen either every few...

hello, I'm searching for a very sensible device that will give me precise reading from sea level to about say 1-2km high. in about 1m resolution. i found this http://www.freescale.com/files/sensors/doc/data_sheet/MPX4115A.pdf sea level is 1013mb will give me about 4.1v according to the graph...

Hi, This will be my project log for this imaginative device. Goals: to build a flying device to be able to control it from ground. to be able to mount a DSLR camera on it for air photography. to be able to control the camera - including tilt and swivel. and the most important - to be able to...

Hi, I have to measure altitude over the ground (on a flying object) I came across the ultrasonic module: http://cgi.ebay.com/Ultrasonic-sensor-distance-measuring-module-Arduino-AVR-/150576396634?pt=LH_DefaultDomain_0&hash=item230f0d795a the range of ~5m is ok for me, my question is - does the...

Hi all, I'm building some sort of VTOL, hovering craft, I'm searching an ANALOGUE sensor that could give me the angle of an axis. actually i need 2 axis - X and Y, altitude is not relevant. that way the picaxe could know the current tilt, and compensate it using the motors. i personally prefer...

I have to drive an IGBT device (like a MOSFET) its datasheet tells "turn on energy" = 2 mJ (at gate voltage 15v) 2mJ at 15v gives out 27uF = 27,000nF = 27,000,000 pF well, ok.... say that. now i'm looking for a driver, i found this one which is one of the strong ones in the market...

Hi, I've seen the DSO nano thread, discussing all kind of scopes. I'm looking for a cheap scope that can give me what i need for the minimum price. PC based is great. USAGE: I will need to measure very high currents for very short times. in other words, measure large capacitor discharge with...
