The schematic from post #1, with 74HCT244, works verry fine !
But...with IC-Prog and NOT with PonyProg; with Pony I can just reading the eeprom, but not writing ! Enjoy !
Yes, it's the same adapter. And I use with ADMEM01, but this is not mine (I borrow from somebody) and I don't have schematic ; use one CD4069 - not sure.
The PIC is not so cheap...and I have the converter. One 74HCT244 or CD4069 it's quite cheap and I can recover from old PC motherboards. I do not intend to spend much with this simple "interface"... So, I wait for further advices, thank You all !
Hi everyone ! First, I apologize for my poor english. Hope I explain right my problem.
I need to programming some Microwire EEPROM (93C56). So I build one programmer on serial port ; with PonyProg works great ! But...I intend to use one notebook, with USB only ! I buy one convertor USB to...
pic battery charger schematic
Thank You for a such fast reply ! Sorry for my english too... About the schematic : I hope I understand the reason for changing this resistor...Now can I begin to build this great project ! All the best !
atmega32 battery charger
Thank you !
One more question : in the pcb file is one R=0,75 ohmi, instead 1,25 ohmi in schematic. Why ?
...b.t.w. You are wright, my mistake : 1/R eq = 1/R1 + 1/R2...stupid me...
All the best !
charger atmel circuit
Hi ! I want to build this charger, but, unhappiness, I do not found 1.25 ohm resistor or 0.8 ohm. Can I replacing them with 1.2 ohm (@ 5W) respective with 0.78 ohm (parallel of 1 ohm and 0.56 ohm, @ 5 W each) ? Can I use diode BY550-800 instead 1N5904 ? Thanks in advance...
intelligent charger pic
Great schematic ! I want to do this !!!! I have all the pieces, but please post the PCB. Thanks in advance ! The links don't works.
If somebody come to me and ask for one injection, I made it....because I know to do this...and I don't send him to medical school...This is the ideea...All the best to everyone, everywhere...
Thanks for reply ! No, I wish one schematic just for two relay, one for each front window ! When I close the car by remote control, the UCH give me one short positive impulse for about 2 seconds ; this I want to use to lift the front doors windows, for not remaining open after night...I think...
...can You, Sir, indicate HOW making this ? I am verry interested about a such schematic, since I want to do this to my own car (Logan !!! - Mahindra, I guess ?!). Well, I want to build some 'interface' witch, due one impulse (positive !) to lift my windows car...with peak detector, so do not...
