SF-7500 serial cable

Filed under: gadgets, hacks — Tags: , , — guilleml @ 9:12 pm

The SF-7500 has a communication port to synchronize it with a computer as PDAs and smartphones do.

You had to buy an interface to connect between the SF-7500 and the computer serial port, but it was very easy tu build, I did it, but now it’s destroyed because I used the parts for other projects, anyway you just needed a RS232, 4 caps, a D9 connector and a small jack 3-pin connector.

The scheme was really simple, even the protocol used to communicate with the sf-7500 was simple, but you could use an application such as http://web.interware.hu/pclink/addleir.html to sync it with your computer.

You can find circuits on the web to build it yourself:

Or can even buy it for 4$ with the software:

Old fashion PDA

Some years ago we didn’t have tactil screens, operating systems which allow to install software, colour screens…this is what I used:

Telephone book, Business card book, notes, schedule, world time, alarms and private area for each one of them, protected under password.
