This kit has now been updated to include a OSSC 1.6 PCB and case. Price remains the same as the 1.5 kit.

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 Β£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.

    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.

    • BuckoA51 says:

      Absolutely appreciate the feedback, right now I’m really trying to gauge interest in DIY kits and contents so thanks for the comment πŸ™‚

    • KnuckleheadFlow says:

      Not sure what the big deal is about sourcing parts. I was able to find everything I need on Digikey in an afternoon, except the SCART connector (going to use BNCs anyway, this ain’t France) and IT6613E (Ali Express). I also had to make some substitutions, two with different footprints, but I’ll take two bodges over having to wait x months. And flashing firmware is not a big deal if you have a serial connection, FTDI USB serial adapter, Raspberry Pi or Arduino.

      Along with the components, but not the PCB, for Borti4938’s audio add-on, it ended up costing about $150 dollars Canadian all together. If anyone’s interested I can upload the BOM somewhere. You can use Digikey’s BOM Manager and call it a day.

    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.

  3. a1ph4n3rd says:

    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 !

  4. bits says:

    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 πŸ™‚ 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.

  5. Salacorn says:

    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 πŸ™‚

    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 Β£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 πŸ™‚ )


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

    • KnuckleheadFlow says:

      It is no more shady than eBay’s Chinese stuff. I’ve ordered lots of stuff from Ali Express and have had no issues (besides free shipping taking like a month). Stuff has sometimes been packed… minimally, but everything has arrived working. Just stick to sellers and items with a lot of feedback and you’ll be fine.

      • Salacorn says:

        That is true. For me, its really the fact of payment options… not a fan of places online that require your credit or bank card digits. Prefer Paypal for online transactions. I use cash in stores in person. Mostly because once a card is used, those digits are always in that database of that merchant… which is no problem unless a breech or hack occurs. (which did happen with me, and I had to be without $4.5k for 3 weeks). Ever since then, I am very sensitive on where I use my card. However, I recently discovered the world of prepaid VISA, and thus myself have started a few orders on Aliexp πŸ™‚

        This is also the main reason that kept me on the fence from buying this OSSC PCB…
        Sadly… the prepaid cards did not work for this site (since currency was Β£ and seems prepaids only work on the currency of the country they were issued from). Also had a serious family drama that came up… but that settled down, so today I finally caved and just ordered a OSSC PCB just using my bank cards. Just can’t be bothered waiting anymore as I have been wanting to do this project for months now haha!

        • BuckoA51 says:

          This attitude always puzzles me. Why do you trust Paypal over other payment providers? You know their reputation is questionable at best! You know other payment gateways work exactly the same? No bank details are held by us, I can’t see your credit card number when using Stripe any more or less than I can when using Paypal. Anyway, Paypal is not an option for us since according to them we’re an illegal console mod chipping service or some such nonsense. They would also probably have frozen our account since we earned too much when the first batch of OSSC came in.

          • Salacorn says:

            I mean no negative to VGP mate, and I do understand merchants cannot see digits, but get opaque tokens to reference cards as per PCI DSS. I have no worries on the merchants, its the gateways that I think about, which of course are out of the hands of the merchants, and merchants have no control over how the gateway manages their data security. Paypal is an evil in itself for many reasons, and is not foul proof either. For me, it is not about trusting Paypal, it is about trying to minimise the number of gateways my digits go through. Since I already have it, and many places take it, that means one gateway instead of many. Technology and methods are ever evolving on card security. At the end of the day though, stupid bigots that refuse to earn an honest living make it a PITA for everyone else who do. Maybe I overthink, but that one bad experience was a forever change with me.

            Your right about the bloody stupid mod chip nonsense… same with eBay. Anyways, really did not mean to get off on that tangent mate. Appreciate all that you & Marqs do *^_^*

    Hi Bucko,

    For a barebones DIYer, any tips on how to go about flashing the firmware chips? πŸ˜€ 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.

    After assembly of the board, using a suitable USB JTAG programmer:

  8. Sean B says:

    Any idea if and when you will be getting these kits in for the OSSC 1.6?

  9. mfaircloth says:

    ETA on the kits?

  10. jeet says:

    any estimate on when a new supply of boards will go up?
