You reply very fast! Thanks you again.
I thinking if I can use 5v PIC18F or PIC16F if I supply external 5v and connecting GND together?
Also, I see you in South California! Some seniors helping me there too - do you member of any electronics club or group there where they can join too and...
bigdogguru, thanks you for insightful and detailing post!
I ask - possible to make own PIM for Explorer 16 Development Board with PIC16F or PIC18F and use this board with it?
Our department getting grant to buy development board and I do not want them to buy same old FPGA board which we have 100 of and only 10 uses so far.
Need your enourmous experiences in helping make good choice of development boards.
Friends with me interested in learning following PIC parts...
Old senior design project and in schematic I see he uses ferrite bead and capacitor after charge pump voltage output befor connecting to opamp input
Circuit very simple:
1. charge pump uses MAX232 to get +- 12V output from 0-5V input
2. +- 12V output rails from MAX232 having ferrite bead and...
I buy two old style AT SMPS to powering my 3A DC Motors.
Shorted the four power pins - Live to live, neutral to neutral.
But when I turn mains power to AT SMPS, fans turning for 1 sec and shuttuing down.
I know in ATX SMPS you short two pins but something similar too you do in AT style...
Friend tolds me that noise of any switching PSU can be attenuate if I put linear regulator before output?
For example, if I wanting to power +-12V opamp for amplifier, I can uses SMPS say with noisy 15V output and then from SMPS output feed LM7812, LM7912.
Output from LM7812, LM7912 will now...
What you all people use to remove oxidized leads (say you have lots of parts buy in bulk 5 years ago and now need to use some of them, but oxidized leads not letting you solder)
Any chemical to remove oxidized leads?
Sanding/filing oxidized leads not always possible, for example, SMD...
I looking for device that help me split a n bit input bus, or n analog lines into two or more bus at output
Please consideration concept diagram below.
At input there is n bit input bus, or n analog lines
At control there is 2 bit control:
00: input signal not routed to output
01: input...
Few of my PSU's also have 110/230V Switch but when I open the case I see it is not connected - dummy switch!
I will be taking part in international competitions, so there will be lots of people and teams - emergency PSU/Transformer is out of question as origanizing body will not favor only one...
I have around 15 computer SMPS - those grey metal box ones - looks the same since they started coming into market for Pentium III boxes in 2000.
I think they cost around Rs 400 ( ~US$9 ) on the average when purchased new and are very useful in powering robots ( esp. heavy duty motors )
My...
