An Update on those Line Voltage Inducer Cables

I mentioned on the Dreamcast Junkyard Podcast that I was intending to build and sell some special phone cables which add the required voltage for a Dreamcast to connect with a DreamPi setup - official DreamPi cables if you will. At the time I was waiting for a test run of PCBs to arrive, and they have!

There are some minor issues with this PCB revision, but I have a working cable, here it is in all its glory:

As you can see, the power comes directly from the Raspberry Pi itself providing you have a spare USB socket. I've been forced to test this by playing PSO online for an hour, and I can confirm that the circuit works perfectly!

So straight onto manufacturing right? Well.. not quite.

Firstly, obviously I don't intend to sell cables with exposed circuitry, so before I sell any cables I need to get some boxes 3D printed. But more importantly, I think I can do better than this.

I think it should be possible to create an adapter box that plugs directly into the Dreamcast, leaving you to just connect any standard modem cable. Not only will this be more robust, but also be quicker and cheaper for me to manufacture (the cable costs £3-4 alone for a decent one).

The next revision of boards I send off will probably an attempt at this, and as end-to-end design, manufacture, shipping, soldering and testing takes about 3 weeks, I'm afraid I won't be shipping these for a little while.

Still, I've proven that it works, and this is a thing I can build. I'll keep you all updated!

P.S. This has all only been possible because of the electrical know-how of my mate Rob!


  1. Cool, was looking into making up the dream pi but not so sure on how to this as i have a raspberry pi. Will keep an eye out on when you're ready to sell these or even preorder. Well ddone on making and achieving this :)

  2. Let me the first to say PRAISE THE LORD FOR THIS AMAZING THING! You wont belive how many tries i have made to make a working LVI. I love you so much :P

  3. This is fantastic news! Any chance you might post your specs so we might be able to take a shot at making our own?

  4. Any update on this? Thank you so much for all your time and hard work for the dreamcast scene.

  5. Great news!!! I'm very interested in getting one. Keep us updated

  6. Oh wow this is amazing!
    I'd love to get my mates all online!

  8. Are you still making these ? If so how much.
    If not any chance of a schematic ?.
    I assume it is just a step up converter as it just needs 18-20 ish volts

  10. it was a wonderful chance to visit this kind of site and I am happy to know. thank you so much for giving us a chance to have this opportunity.. convert-aux-cables-to-usb

  11. What your saying is fully true. I know that everyone should say the similar matter, but I just feel that you put it in a way that every person can fully grasp. I also love the photographs you put in right here. They suit so nicely with what youre trying to say. Im guaranteed youll reach so a lot of people today with what youve obtained to say.
