I am trying to make a battery bank. I have soldered 9 lithium polymer batteries of 3AH in parallel to give 27AH of total capacity. They are soldered and glued and i can not take them apart.
After doing that i found out that how hard is to make a boost circuit with decent Amps. did a lots of...
ok, everything runs fine now except i have one issue.
When i bring my hand close or touch the thermocouple or touch soldering iron to the thermocouple, the temperature immediately drops to zero and after 5 to 10 seconds everything goes to normal. I have a 10nF cap installed near T+ and T-.
Hi again. thanks for the help. Now i m able to out some numbers but the problem is they are all jumpy. Not stable at all (nowhere near the ambient). some time 2 and sometime 3 digits. thermocouple is just 5 inch long wire. yes i have included 10nF cap at T+ and T- terminals. 3.3V stable input...
Hi all,
I am interfacing MAX31855 thermocouple IC with PIC16f882. I am using MikroC pro for PIC.
Reading the output gives a 32bit number which i stored in " unsigned long temp". useful bits for me are D30 to D18. and i have no idea how to extract this from 32bit number. Any help would be...
I am willing to buy Rigol DG1032Z and here are the two sites"

In my country i get the FG in 650$.
Do you recommend...
In mikroC example we connect GLCD to any port by defining this statement char GLCD_DataPort at PORTD;
This dedicates all pins of the port and not allowing you to use specific pin of the port.
For example i am using PIC 16f887A (28 DIP Package ). I cant use portB as i need the interrupt pin and...
I need to make my own front panels. What kind of front panel sheets are they using? Is printing possible on them? Pics attached,thanks.

Thanks. Good Suggestions and you made me understand. But kindly explain these above 3 point in a bit detail.
1. 330pf to make it act like integrator, but will if effect frequency?
2.Affect of 10k?
3.470pf? from pin 1 to Gnd eliminates osc but what will it do from pin1 to pin2?
I want to design a simple precision DC electronic load as those of Bk precision are expensive and they are actually when you think you can build one.
AS you can see in the fig i am using MAX44248 because i have already ordered them.I am not using direct feedback to the op-amp1 but via op-amp2...
Hi, soldering smd packages like so,1206,sot are no problem with bear eyes but they also put some stress and i am a person with glasses. i have a magnifier lamp of 2 or 3x and works well. but now most ics of my needs comes in MSOP or TSSOP packages. which seriously i cant solder. so i am in need...
Hi guys. As the title says i need a waveform generator for learning purposes. i am mainly interested in sweep function so i can play with filter designs but added functions are bonus. i have narrowed my search to two generators so plz help me out for the pros and cons, thanks.
1. this one is...
i have 240x128 lcd. at the back side there is a place for smd connector(bottom left). so what type of connector is this so my search will go alot easier on digikey, thanks.

I thought that but i think there is problem.the command for that is sprite which draws the image in a specific rectangular area. that rectangular area if stacked on the curve of the circle then it would remove most of the previous circle because of its background.
Compiler: MikroC 6
Controller: PIC18f452
LCD: T6963C 240x128
I want monitor Water level. So a tank goes to my lcd and problem is how to fill it.
Look in the figure, there are two tanks.right one is easy, i just have to draw straight lines in for loop. but left one is more realistic but how can...
So i managed to buy Version 6. My first compiler purchase :) Must say its an expensive thing. Anyway everything is working fine now. Hex file is being generated correctly and wide and narrow option of GLCD is working great. Thanks "jayanth.devarayanadurga" and "tpetar". You guys have been great...
