Product COM-10136 | about a year ago

The first micro project I built was 48ch led controller, used 3 of these and a Picaxe 28X1 so I know for fact that these work with Picaxe but I did need to uses a decade counter to generate all the necessary clocking signals because of the inability of the Picaxe to generate 2 different frequency of PWM.

In the data sheet the “CHAR” labels could be more clearly explained. I eventually figure out that they are a type of ASCII command and found a table that list the hex equivalents for each “CHAR” command you have listed. A suggestion for future revision of this document would be to include the hex version of each command statement instead of only listing the keyboard command, since they are not always available when controlling the lcd from a microcontroller

Thermodynamics suck. the reality is while you can extract energy from the water, with such a low difference in temperature you wont be able to extract much of the energy. all system have inefficiencies and in general the the higher the delta T the more efficient the system is, but at best you looking at system efficiencies of 60%. as far as directly extracting the energy in the water the only direct approach without going into extremely exotic materials is thermocouple but the efficient with thermocouples is very low 6%@1000C they’re not practical. a more efficient approach would be a sterling engine based system but again they’re not very efficient at low temperature.

That it completely. RoHS is horrible when it comes to extreme environments. Which is unfortunate because so many parts are being made to RoSH it is getting difficult and or expensive to get new parts that are not RoHS compliant.
