FrankenMobiWatch

Posted on by

From a Mad chat on Mobitopia about watches, we have come up with what we want in a decent watch that got the name the FrankenMobiWatch

? Analogue or Digital
? Solar or Kinetic
? Radio Controlled (From Rugby and or Frankfurt)
? That can switch times zones Automatically (possibly via GPS)
? Small form factor
? Deluxe Options MP3 & USB memory (so that the cheapskates don’t have to pay for it if they don’t want to! )

Icom OPC-478 Connector

Info for this Connector was obtained from ICOM CI-V Hardware Page

Here are some images of the OPC478 connector someone is making for me.

Icom OPC-478 Interface.

The ICOM design for the OPC-478 interface is a simple transistor circuit used for cloning. The version by Chris VK3JEG http://uk.geocities.com/blakkekatte/hardware/opc-aus.jpg gives equivalents for the transistor and diode parts. That version is the one commonly found on the internet. However the one from ICOM Japan’s site http://uk.geocities.com/blakkekatte/hardware/opc478-japan.jpg has a few modifications. I have added the transistor and diode equivalences from VK3JEG’s copy of the earlier version of the interface. WA0SXV http://www.wa0sxv.us/ci-v.html has some reservations that this design might not properly implement the RS-232 protocol.
