build eeprom programmer

[blueangel666]

Hello guys !
After my failure with the pictures of the scenic, I wanted to try with the construction of a programmer EEPROM 93c46

I found a diagram on the internet, on a German website, where practically the programmer uses the parallel port, and, strange thing, it has no resistance or diode or capacitor between the port pin and the pin of the EEPROM. It might work ?

don't stop on the first schema found. even just typing on the ****** images "93c46" come out of the box and anything else that is devoid of electronic elements....

[blueangel666]

Yes, I torvati other. Including the ludipipo, JDM or other resistors and capacitors.

I asked if it can? work. If anyone has tried it

since there are components you can make the connections and check for yourself if it works, definitely use circuits with resistors and capacitors should be more stable in the planning stage.

Yes, these are valid, and you can also plan other families of serial eeprom with the same programmer as well as? the PIC.
Do not save on components (diodes, resistors and capacitors).

Let alone, not ? to save money. For what is the cost of components....
Just wondered if anyone had ever tried these patterns without components. However, he is right, "Mec" , the only ? try.
Of this for? programmerebbe, if it ever worked, only the 93c46.
As soon as I have everything, let? a test and, if positive, place the schema. If anything would help someone.
You do? know!!!

the ludipippo works, I have tried personally some time ago, and the memories that pic ,them programs without problems.
Certainly, the pattern of parallel work, we look forward to your opinion

Guys with a few euros is a eprom programmer sensational product from the silancode the model and zp20 I believe that the costs from 30 to 50 euro and covers a lot of families complete software.. not it's worth to build one face only..

You definitely have a professional product but with the homebuilt spend a couple of euros

according to me autocostruirlo does not agree,? real savings on something, but then you have to see if it works well and if you have the software to make it go
