Dunno what pitch they go down to, have to ask the fab houses on that if they do it. If you had a pcb that fitted over the entire top of the video encoder, cut out in the middle with corresponding pins on sides (some for location fitting) and then a small pressure clamp over it then something like that might work as a solder-less fitment maybe. Other than that it's those spider springs which are pretty terrible really. Can't imagine 20+ row of those being reliable. I remember a solderless modchip like that for the Wii. Just clamped right onto the IC... that would be GREAT. Quote Link to comment Share on other sites More sharing options...

I think I've probably gone a bit too long with the pads maybe? Definitely need to reduce the via hole size along with the castellated holes on the edge. This is my first attempt at a flex cable so a learning curve was expected as I wasn't sure how my CAD designs would translate to a physical object. 1 Quote Link to comment Share on other sites More sharing options...

Was just the idea, don't know where to get them etc. Guess the best option would be to start with the pin spacing sizes... prolly .67 or half mill or sommet is it? Not looked yet myself at the encoder though soldered to them several times, not measured them or looked at the chip pdf yet. Might find an IC socket with same pitch and cut the socket up to correct lengths, soldered to a pcb and size to press on with a clamp. Might work. Pcb would have to be deadly accurate.

They gave me some daft quote for the ribbon flex at 30 off - so told em to stuff it and thought since I'd not built the HDMI boards I'd just use ribbon cable at mega fine pitch for a challenge lol So not done anything with that yet.

NeMesiS Posted June 19 Author Report Share Posted June 19 (edited) Pretty sure the package for v1.0 to 1.5 encoder is "QFP-80" PLASTIC QUAD FLATPACK LEAD PITCH=0,65 PKG.THICKNESS=2,00 EDIT: I say "pretty sure" as I'm feeling pretty burnt out today and I lack the energy to double check this atm.

NeMesiS Posted June 19 Author Report Share Posted June 19 Never mind... SIB-109-02-F-S - Samtec - Spring Loaded Connector, Compression Connector, 2.54 mm (newark.com) Not a cheap option... I find solutions for solderless installs tend to get expensive. 1 Quote Link to comment Share on other sites More sharing options...
trencherfield Posted June 19 Report Share Posted June 19 I've been looking for you and the company that made that appears to have stopped making it, plus I can't find a small pitch one either. I know it would be great to have something attach to the encoder so buyers could easily install it. I know it's no good being easy for you, me and others who do this kind of work and smaller, it would help a lot of Xbox fans out if there was something easy. 1 Quote Link to comment Share on other sites More sharing options...

Yeah it was a dead link on the manufacturers site from the pic I found. If I find anything good in future for it I will let you know, since I'll only install the ones I make myself.

This is my first attempt at a flex cable so a learning curve was expected as I wasn't sure how my CAD designs would translate to a physical object. At the moment, I think the pads are probably fine. It wouldn't hurt to experiment with shorter ones if it's easy, but I don't see an issue. If you wanna shorten them, make them perfectly symmetrical around the via.

NeMesiS Posted June 19 Author Report Share Posted June 19 (edited) I did have an attempt at a solderless solution for the Xenium modchip. I dubbed the first stage the "mostly" solderless adaptor as D0 still needed to be soldered. It was for v1.1 to 1.5 only as v1.6 needed a different adaptor and v1.0 LPC's are usually filled with solder. Since there wasn't much interest in it, I discontinued the idea. I based the design on the original XeniumSPICE (v1.6) solderless adaptor. For second stage I would have looked into getting the probing wire I would have needed for D0. Stage 3 would have been a complete clone of the SPICE adaptor. LoL... I just noticed in this random image I found that the pins are all bent. No matter how fool proof you make something there's always someone that will Suprise you. Edited June 19 by NeMesiS 1 1 Quote Link to comment Share on other sites More sharing options...
Dtomcat18 Posted June 19 Report Share Posted June 19 Other thing that could be an issue is while it makes contact… is it enough for interference free video. I’ve seen a few installs that looked ok… but had artifacts in video. A bit more solder resolved it. Also larger contacts like the compression connector above have more surface area to all interference in. Essentially you could be trading ease for video quality (playing devils advocate) 1 Quote Link to comment Share on other sites More sharing options...
big F Posted June 19 Report Share Posted June 19 4 hours ago, NeMesiS said: Nice work by the way, nice board too. I like the boards with copper looking traces. You might be interested in this: XeniumICE by NeMesiS - Page 24 - www.emuxtras.net I compiled a list of replacement capacitors for all versions. Replacing the CPU capacitors with polymers can significantly improve picture quality. This needs a thread of its own. The ticking time bomb of capacitor failure is going to start being a thing soon for the OG, just as it has for all my 80’s and 90’s consoles and computers. Im not sure where but I read that modern capacitors have a better tolerance than the crap they fitted in the older day. So the general quality stuff is now as good as the top end stuff was back when the 80-90’s stuff was made, considering the manufacturers would only use cheap or middle of the road stuff, replacement should tighten up timings etc and make consoles better. 1 Quote Link to comment Share on other sites More sharing options...

nikeymikey Posted June 19 Report Share Posted June 19 Late to the party here. But I just basically want to mirror what the other have said. This is excellent news that we are going to have a Stellar competitor of sorts. Keep up the great work @NeMesiS I'm sure there will be a lot of demand for your project. 2 Quote Link to comment Share on other sites More sharing options...

I remember them being unreliable as time went on too, since the only relied on direct, downward pressure. How the hell would somebody even bend the pins like that? lol. That seems highly improbable. 2 Quote Link to comment Share on other sites More sharing options...

I also think you need to be careful with bigger pads that you don't have contact with the via's around the chip. Quote Link to comment Share on other sites More sharing options...
