    ReadADC with automotive level sender

    It is important to look into the final application. In the past (long ago) I have looked at this and at that time the level sensor was a variable resistor like yours, that was hard wired to the car's chassis. So one of the pins is chassis ground, and the other goes to an analog gauge. The other...

    Picaxe 40M2 and variables using Blockly

    If you convert to PICAXE basic, you have a max of: 32 bit variables (1 or 0) eating up words w0 and w1 + 52 byte variables (0-255) eating up the rest of the words (W2-27) So the absolute maximum is 84 variables. Then thee is 1024 bytes scratchpad memory. That memory can not be used for...

    RC indoor air combat using 08M2's

    Video is not available. Due to current Corona measures we cannot have a camera man indoor.

    RC indoor air combat using 08M2's

    Our local model airplane club flies outdoor when weather allows. During autum and winter we rent an indoor gym, and fly indoor. With very light depron and EPP airplanes. Since the indoor environment challenges with it's stone walls (that cause damage to the plane when you hit them) it is...

    Li-Fi transceiver

    Although I can envision point to point communication, but to achieve sufficient signal to noise in a omnidirectional system (like WIFI) you may have to flood the room with light (visible or invisible). Using IR will suffer greatly from heat sources in a typical environment (electronics, candles...

    Fuel Gauge for RC airplanes

    The code contains a lot of remarks also contained in previous posts, but the actual code is pretty small. The only thing I have not yet solved is getting some defaults in flash memory so the system works even before you do your first calibration. So initially the system is useless until you...

    Fuel Gauge for RC airplanes

    The output of the DAC is connected to a "voltage" telemetry input of the RC receiver. Attached photo's show the Telemetry reading on the transmitter LCD (the value ExtV shows the tank is 1/3 full (1.5V of 4V range)). Another photo shows how the stuff is build into this airplane. From left to...

    Fuel Gauge for RC airplanes

    Now we come to the moment the PICAXE comes into play. The M2 series of pickaxe chips have a function that is called "capacitive touch" using the TOUCH and TOUCH16 commands. It is designed for capacitive touch buttons (keys) so you can operate a system in a wet or unfriendly environment...

    Fuel Gauge for RC airplanes

    The fuel tank is placed in the airplane hull, that typically is made of foam, glass fiber, or balsa covered with foil. These material do not shield electrical fields at all (carbon fiber does though). That means that the capacitive plates are also sensitive to the world outside the airplane...

    Fuel Gauge for RC airplanes

    The fuel in the airplane tank is a mixture of methanol, oil, and nitro. It is quite an aggressive mixture. Putting electrodes or sensors inside the fuel is risky, corrosion is to be expected. Therefore a solution was engineered to place electrodes outside the (plastic) tank, and measure the...

    Fuel Gauge for RC airplanes

    Typically RC airplane pilots that fly combustion engines have no clue how much fuel they have left. They fill the tank at start of the flight, take off, and use a timer to tell them when to land the plane. On a nice sunny day when life is easy they land the plane and discover the tank is still...

    RC switch

    For my model aircraft I needed a remote controlled switch for aircraft lighting, and other functions. The aircraft lights consist of 12V LED strips. This switch allows 2 groups of LED's to be controlled independent. The switch uses an 08M2 to convert the PWM RC input signal and drive the power...

    RC nicad/nimh battery gauge

    In remote controlled airplanes, a 4.8V (4 cel) battery is used to power electronics. To prevent flying an airplane with an empty battery, this battery condition checker is developed. It is based on a PICAXE 08M2, powered from the NIMH battery, measuring the voltage with the A/D converter. The...

    servo and sevopos ... a startup and shutdown problem.

    In a setup I am using digital servo's that are tested to hold position in absence of input signal. The only thing I need is a clea way to start the servo pulse chain for 7 servo's, and to end it in a clean way. But I have run into the following 2 problems. using 28X2 Problem 1: starting the...

    serrxd timeout problem

    Hi Buzby, Thanks for the welcome and the quick reply. I have simplified the program to loop around serrxd and sertxd (basically echo-ing everything that comes in via the serial port) but as long as I am in that loop I can only re-program the chip if I hard reset. That is nice for development...

    serrxd timeout problem

    After programming picmicro assembly for more that a decade, I found the picaxe processors on the web. And they offer quite a bit of functionality that I had to craft myself in assembly before. So I ordered a 28X2 and build a breadboard, so see if this picaxe system is any good. I am surprised...
