Re: ESR Meter
Hello Rob welcome aboard,
Actually it’s not necessary to calibrate this device. I would say this device is a comparator. You can compare good known capacitors with bad once so you can have an idea. I strongly recommend find some good capacitors with different farads range...
Re: ESR Meter
Hi my buddies Bkelciov & Kripton, How are you guys doing? I hope you guys doing great. Well I just completed Elector SC2005 Semiconductor Analyzer it works excellent. I had problems with it from the beginning after I read manual I did set up the right fuses thing works fabulous...
Re: ESR Meter
Great Job pal and we all have to appreciate your voluntary service. Very nice projects with minimal components.
My problem is what to choose.
Thanks for your help to the world.
With Regards
Haran
Re: ESR Meter
Thank you very much Bkelciov, You are my Electronic buddy. I would like to start another useful project testing FETS, Transistor & SCR on circuit something like Peak Atlas Component analyzer.
Do you have any PIC based projects available ? Let me know.
Thanks for everything I...
Re: ESR Meter
Finally My ESR tester is working. Thank you very much Bkelciov without your help I couldn’t have done this project. I bothered you almost a week and you answered every single questions Thanks for your precious time.
The problem was I didn’t connect pin 7 & 14 on CD4066.
Now...
Re: ESR Meter
Thanks Pal, Without Capacitor it shows ESR 0.000 and i couldn't find the calibration on page 1
MY CONFIGURATION IS
VT1 = BC327 (is it okay to use this Transistor?)
VD1,VD3 =1N4148
There is no bridges in LM393 VT1, VD1 & VD3 areas now i'm worried what's going...
Re: ESR Meter
Hi buddies, Well there is a good news my project succeeded 75% only. Now the display's working and showing everything the problem was there was a invincible solder bridge between D7 & D6 on the display panel PCB continuity tested failed but a magnifier found the bridge.It's all...
Re: ESR Meter
Thanks buddies. This is the display i'm using https://www.dipmicro.com/?datasheet=TINSHARP-1602A-01T.pdf .Also the online store where i bought this display says HD44780 is obsolete controller and was replaced by newer backward compatible SPLC780 and ST7066 types. [/U][/B][/B]...
Re: ESR Meter
Buddy Bkelciov Thanks for your encouragement. Also i have to thank the other buddies Costas and the guy who gave me an idea to do this project Kripton Thank you guys.
Well there is a progress on my ESR photos attached. The thing is i'm not familiar with pf Caps so i used 220(the...
Re: ESR Meter
Thanks again pal Herewith i'm sending you the closeup shoots. The Pic programmer i used is Enhanced PICkit 2 with Pikit 2 Programmer(Micro Chip). Here is the Hardware link MCUmall Electronics Inc. A low cost EPROM EEPROM Atmel PIC I2C SPI programmer online store

Re: ESR Meter
Thanx pal. Well Bkelciov & l ruled out most of the causes but still no luck. So i figured it could be the Display or the PIC. Well i used same blue display with same 18k and 1.5k config all i saw was the top row lit without any characters.
What do you think?
Thanks for you time...
