Does this mouser project contain all components I need?

[renegadeandy]

Hi everyone!

I have ordered the OSSC DIY kit(with donation to Marqs!). On the product page (https://videogameperfection.com/products/source-converter-barebones/) it has a link to a mouser project https://www.mouser.co.uk/ProjectManager/ProjectDetail.aspx?AccessID=c735e03115.

This mouser project has a lot of components – which looks good. What I *can’t* see in the list, is some of the components in the advanced kit product – https://videogameperfection.com/products/source-converter-advanced/.

For example:

1 x Altera Cyclone 4 chip (EP4CE15E22C8N)
1 x Aluminium cooling heat sink
1 x Component video connector (3 x RCA jack)
1 x Firmware chip (pre programmed)
1 x IT6613E HDMI interface IC
1 x Right angle type SCART socket connector
1 x TVP7002 IC chip

Are those in the mouser project link I put above? I don’t think that they are. And if they are *not* is there somewhere a complete list of components so that I can be sure I will have everything? If I did order the Mouser project contents, what is the delta that I would be missing in order to make the DIY OSSC board complete?

Many thanks for all support offered!

I have my BOM at home, with details of which components weren’t available through Mouser, and also the sites I got them from. I’ll put the info up later today. It turned out to be a pretty expensive exercise, from memory I think that DigiKey charge ridiculous postage rates, at least to Australia.
Anyway, I’ll post the info here and you can use it as a starting point

Hi BonzoBits,

That is very much appreciated – I am surprised there isnt just a simple list which contains all components! I am pretty keen on getting started if somebody can help.

BonzoBits – did you get it working in the end?

[b0nz0beavis]

This should help:

Chips:
IT6613E Ordered from AliExpress
TVP7002PZP Ordered from AliExpress
EP4CE15E22C8N Ordered from AliExpress

Other components:
T6-13B
or
CS-107 – Right-angle SCART connector – Ordered from element14
PJRAN3X1U03X – RCA Connector – Ordered from DigiKey (you can probably find a supplier with much cheaper shipping rates. Also, avoid ordering the red/white/yellow connector. You need the red/green/blue one).
GD024 – Heatsink for TVP7002PZP – Ordered from AliExpress. They come in a bag of 10 or so, they’re cheap though…

And yeah I got it working with only one small hiccup which Marqs was able to trouble-shoot for me. It’s a lot of effort ordering components, assembling the required equipment and finally soldering the numerous components, but it was very satisfying and the end result is an awesome product and some very delicious visuals for retro consoles.

Thanks for this BonzoBits. So it was everything on the mouser link – plus these?

The kit https://videogameperfection.com/products/source-converter-advanced/ is now back in stock. So If i buy that – plus this – https://www.mouser.co.uk/ProjectManager/ProjectDetail.aspx?AccessID=c735e03115 will I have everything I need? (already ordered the barebones kit).

Seems like you’re on track. All I did was order everything available via Mouser (I think one or two items were available but out of stock when I placed the order) and then tracked down and ordered the rest.

I also found it helped to mark all the items off the BOM as they came in, it helps to have this certainty when there are so many items to keep track of. Also, you might want to consider ordering a few spares of the SMD resistors and caps. For components where 5 or more are required, I upped my volume by 10 or 20 percent as I was anticipating losing track of a couple during construction. I think I ended up losing two resistors somewhere under the coffee table so it was nice to not have to drive to my local electronics shop for replacements.

The BOM on this page lists all the required items. It also specifies which ones are not available on Mouser: https://www.niksula.hut.fi/~mhiienka/ossc/diy-v1.5/

I believe this BOM was created by Marqs. I used it when ordering all the required stuff last September. If you use it as a checklist, it will help you make sure that you’re getting all required components.

Great – all ordered and will mark of arrivals as they reach me! Thanks for your support BonzoBits.

I am considering using a soldering pen and hot air gun instead of using a soldering iron considering the size of these components and number of pins on the ICs etc. Any advice on which one I should buy – this will be the first kind of project dealing with these sized chips so far!

I would suggest watching vids on YouTube and assessing the various options, then pick the one you are most comfortable with / has the appropriate amount of challenge factor. You should also make sure to have decent lighting and magnification for inspecting your work for bridges, etc.

I hand-soldered the entire thing, so I can’t make any recommendation on other techniques such as hot-air guns. I learnt an f-tonne of useful stuff from YouTube though, from how to drag-solder, use solder wick efficiently, etc, so make sure you take advantage of the knowledge available there.

Hi BonzoBits – good idea I will watch some videos. Are there any in particular that you found helpful?

Also – on the DIY instructions :

https://www.niksula.hut.fi/~mhiienka/ossc/diy-v1.5/

How did you actually do the assembly, what process did you take. As far as I can see, the following is how it would be done:
——–
1/ Look at the top_traces png and then correlate a reference like C23 – to the excel spreadsheet
2/ find the ceramic capacitor 0.1u? and solder on, rinse and repeat.
——–

I just want to make sure I don’t mess this up!

[b0nz0beavis]

I didn’t keep track of which vids, I just searched up a few topics:

– hand-soldering SMD
– solder wick SMD
– Re-flow ovens
– Etc

It’s just a matter of absorbing heaps, keeping track of the useful ones.

As for process, I don’t remember lol. Whatever you come up with will be fine, just take your time as backtracking and looking for mistakes takes ages. The page with the BOM, I’m pretty sure Marqs’ workflow is one of the other documents on that page, so keep it handy as it does have some good info about the few components that need a ground connection.

There might be some useful stuff in the DIY Support Club thread on these forums.

I ordered the DIY Kit and the DIY advanced Kit, when assembling, I noticed I still had to buy eight M3 bolts and four M3 nuts.

It’s not hard, soldering pen and hot air will work well, for hot air station a normal Chinese hakko clone like 858D+ will work (that’s what I use, cost me about $35), when it comes to soldering pen/iron you will do yourself a huge favor if you get a brand one right of the bat, Weller, Ersa, genuine Hakko or JBC. Depending on where you’re located availability of certain brands varies, if you’re in the EU then I recommend getting a Ersa straight from their online shop, good quality for fair price.

I use the Ersa i-con Nano, the pico is a little less but it’s also not grounded which you should always have when working on electronics, but any of the above mentioned brands are good.
i-con nano is listed as 80W with the pen but station is specced as 68W, it’s a very handy pen-style iron and haven’t found anything that it can’t handle when it comes to electronics, it’s easy to handle and you can switch both tips and pens meaning once you get a station you’re set.

Overall you need some magnification and a good light to check your joints but other than that doing 0603 isn’t that much harder then regular soldering, a decent lead-based thin solder wire will do or use paste, as for the chips simple drag soldering works just fine, paste will make it easier to connect the ground plate below.
Heat gun works for chips as well but honestly I did both on my board (since I had to redo a lot due to getting the wrong chip etc) and hand soldering the chips is actually faster in general but if you have to remove or redo them an hot air gun will make it much easier.

So if you have some soldering experience and decent equipment this board isn’t really that hard, just go slow and methodically, look at the layout before and check values, do that and you shouldn’t really run in to much problems.

EDIT:
And FLUX! you can never have to much flux, a good flux will help a lot rosin or resin doesn’t matter, a no clean one will well reduce your need to clean it. If you think you have enough flux then add some more!
