Making a Siemens C55 Data Cable

Luckily, after searching for a while in my “old power supplies box” (a box where I store all the old phone chargers and power supplies), I found two chargers for old Siemens phones, having the connector that I needed. However, I quickly realized that they only had the VCC and GND pins and I needed a connector with Tx and Rx pins too.

After putting the pins inside I had to find a cable with four wires to solder them to the four pins. I ended up using a damaged USB cable that I had laying around and removed the USB connector. After soldering the four wires I filled the inside of the connector with hot glue and closed the housing of the connector.
Later I’ll make a post about the full eLab Hackerspace‘s GSM entry system (now available here) so that you can make one for your local hackerspace or just gather some ideas for your next project.
