StampPlot is ok in a limited way. big faults are : BS-2 lacks ADC input pins , and the BS-2 language uses commands for which there is no equlvalent in PIC basic.

this msg is for those who are looking for a relay board for their -18x project. here is some of what has been learned using one from .phanderson.com : the $50 . 'serial relay & optoisolator module' he offers lets you control up to 4 relays at once using the serial link. or the opt'l opto' link...

most of mine are 10 years or more old. the result is lots of intermittent contacts with the wires and picaxe chips on circuits being built. they will run, then not run depending on pushing on the wires that join all the parts. frustrating. i have a heathkit 41khz ultrasonic cleaner. its pan...

the following is an idea to promote understanding of what people post here. the circuit being worked on can be sketched and scanned with my HP PSC F340 & saved in any of 13 formats. including *.jpg and *.pdf it is desired to be able to include a picture of the circuit with the...

the signal source to be measured is the output of a AD626 diff'l instr' amp. and has an output impedance of an ohm or less. what value of series resistor should be placed between its 10k load resistor and the -18X adc input for a reading ? i.e. what value of impedance is the -18X expecting to...

hi, does anyone have code for this combo of pressure sensor and chip that they would be willing to share ? or do you know of a different pressure sensor that is as easy to use as the 18b20 temp sensor is ? thanks, bw
