Got mad soldering skills? Then build your own Open Source Scan Converter (OSSC) by ordering this DIY kit. This kit contains just the bare PCB and pieces needed for the standard case. All other components must be sourced by the customer. Many of the components can be sourced from local electronics suppliers or from online suppliers such as Mouser.

Optionally, you may also donate £3 from the price of the kit to Markus Hiienkari (Marqs), creator of the OSSC. We highly recommend this, it is a great way to say thank you for all the hard work Markus continues to put into the project and also to help fund future developments, such as firmware updates. Every donation will be paid to Markus in full, with no deduction for processing fees, etc.

The OSSC is the ultimate lag-free retro gaming linedoubler and processor. Now there’s an affordable way to use your retro consoles on your PC monitor or TV in perfect quality. No more bad upscaling, no more interlacing artefacts, no more high input lag, the OSSC is a dream for retro gamers and collectors! For more information on the unit see the product page here or our review here.

Please note, this is an advanced DIY project that requires significant soldering skills. We cannot provide technical support with fitting and assembly. Community based technical support is available through our forum here, but we do not offer e-mail or any other technical support for this product. Unfortunately we cannot offer refunds for kits that have been damaged due to accident or misuse or incorrect assembly.

You can also optionally purchase our “advanced” kit that contains some of the harder to find components, as well as a pre-programmed firmware chip.

    This is almost awesome. For some I’m sure it’s great!

    Hopefully you are able to release a more complete version in the future (as you have hinted), I am more than happy to solder together a kit. But I don’t want to faff about sourcing parts from all over the place.

    Also it would be good to indicate in the documentation an idea of the price on the BOM so people can easily scope if it’s in their budget or not.

    Not trying to be negative or critical, just giving you some feedback. Looking forward to a potential more complete diy kit or for my preorder to come up.

    This is silly. Where the hell I am supposed to get and TVP7002; EP4CE15E22; IT6613E and especially S25FL216K with firmware?! If this kit is intended for manufacturers who have access to those parts and firmware burners – they have resources to make their own PCBs!

    Please offer more complete kits for your average home DIY enthusiasts.

    Ever thought of making a hybrid kit, with some of the fiddly SMD components pre-soldered, with just the larger through-hole components left for people to source and solder themselves for people that only have access to basic hand soldering equipment.

    Keep up the good work !

    So the current DIY is more for commercial purposes than hobbyists? IE, attempting to source these parts is likely to be an exercise in futility unless the DIYer already has experience in this area?

    • BuckoA51 says:

      It’s not for “commercial” purposes no, why would we do that??? It really depends what equipment you have and have access to. You will need some way of programming the chips that’s a stumbling block for some we understand.

      • bits says:

        Yeah, that question was both poorly worded and a bit dumb. Whoops 🙂 I was thrown by Volo’s ‘firmware burner’ reference as it initially sounded to me like a specialised and probably expensive or hard to access piece of equipment.

        That said, I’m making the most of this sick day from work, by ordering up components and researching the stuff I don’t know about.

        Good luck to any other amateurs that are having a go at this.

    I always appreciate enthusiasts who not only only release their work as open source, but also provide the PCB(s), so a pre-empative thanks to both Marqs and VGP for getting this wheel spinning 🙂

    I deffo do not recommend beginners to attempt this – SMD work alone takes practise, let alone on this level of complexity and tools required. Considering the price of parts+postage from various vendors is almost near the cost of the built version (You WILL have to buy from multiple vendors), building OSSC yourself is really for the aficionados and those who just can’t wait for the pre-orders.

    That being said, I’ve seriously am contemplating giving this a fair go. Tools not an issue at all. The HDMI transmitter (IT6613E) is the only show stopper. I reckon I possibly have found sources for everything else:

    VGP: PCB OSSC kit
    Digikey: Triple RCA Jack
    Ebay: SCART Connector, sticky aluminium heatsink
    Mouser: Everything else except U3 (IT6613E)

    Excluding post costs, that is about £105

    I believe I have found a product I could salvage an IT6613E from (SY-ADA31025) but won’t know unless I buy one to see. Aliexpress seems to have sellers with the IC… but I honestly always seen Ali as dubious and never can get myself to order anything from them.

    I’d post links, but am not sure if that is allowed.

    All that being said, puts me on the fence of diving in, or waiting for either the product order or kit with parts release. None the less, much appreciate the work and research behind the OSSC, and best to all!

    • bits says:

      Mate, I jumped in earlier this week and have ordered the kit as well as all the components available on mouser.

      I would appreciate any help you could give with the following:

      (Found these three on aliexpress, but given what you’ve said and the advice from some dude at the electronics shop today, I’ll hold off using them until other options are exhausted)

      (This one I found a baifuda, but the minimum order is 5000 so out of the question until I set up a commercial operation 🙂 )


      In the interest of not spamming any links here, I’m on the shmups forum as bonzo.bits if you could PM some through.

    Hi Bucko,

    For a barebones DIYer, any tips on how to go about flashing the firmware chips? 😀 IE, do I need to by some kind of hardware, or is there a specific type of service provider I should google?

    I have received my shipments from Mouser and DigiKey, just waiting on the ICs from aliexpress and a Scart socket and I’ll be good to go.
