You sound terrified when soldering M :) To clear solder bridges I personally add more flux and use a clean iron tip at the end of the chip legs. The heat of the iron always pulls the solder towards it, just have to keep the tip clean and the bridge flows onto the tip, no need to use solder braid then 👍 *edit ah you worked it out at the end cool!
BBC Nerd update: I've just managed to load Alien8 by playing a .wav file on an old phone, which is plugged into a small short range radio transmitter tuned to 90.5FM. I then plugged a radio into the back of the BBC, 3.5mm to DIN cassette socket, watched it load perfectly and now have a massive NERD smile on my face. I posted this in the hope that it'd make you smile during these insane times. (the radio transmission was only over a 6 inch distance, but I'm still laughing 10 mins after doing it)
@@msknight5 Nice work on the HDMI BBC output! Some nice clear images there. Are you going to publish a few gaming videos from your good work? (btw: which capture device are you using?)
@@TheVicar Well, therein lies a long story. Can't capture audio from the BBC... the MSX is going via a cheap SCART converter and both the V1 and V2 GamerLite units are causing HDMI issues. Still got a few things to sort out. Will make a video on it when all done.
I had my heart in my throat watching this as I'm going to do this myself. I guess like you say that 10 units will result in at least 1 working result! I've never tried using the thick flux that you're using there, nor tried soldering such chips onto boards. I use a flux pen, so its pretty much fluid and I use a much smaller solder tip, but this is totally each to their own, especially with such zoomed in work. How much does the purchase of 10 board kits cost? In terms of sound output, I'm not concerned about HDMI carrying the sound as I did the BBC audio mod, which you published a few years ago (cheers!), enabling me to feed sound out to earphones/amp. So if I capture a BBC game I'll just direct the audio out to a PC, recording the sound as I play, and add the sound in later to the video edit. I don't even have a screen capture system to record yet, so I might be talking **** at this moment - (probably late night alcohol making me not think about this properly whilst watching) You've done some very nice close up video recording there Michelle. I'll watch it all again when the booze has worn off and review my comments aswell. The one thing I'll say about using braid to remove solder is each time I remove any solder, I'll cut the braid every time. It saturates and spreads up inside the braid very quickly and I'm always worried that it'll add some back to the area I'm working on or just not carry on removing enough unwanted solder, only heating the area. I probably go through a reel of braid too quickly but I guess thats one area where not being economical is OK. I also use plenty of masking tape to hold stuff together when soldering/working on stuff. Cheers for the vid and sorry if I sound critical. If so, plz blame the IPA (8
First question... cost. All the parts from Farnell came in at £165 and that was a month ago. (I also ordered some D-Sub sockets at the same time, so knock a bit off the total for that) The resistor packs are still not with me yet. Maybe next week. Ten boards from Seeed were around £12. All that includes delivery as well. That's not including the cost of the Zero, although I did get header pins from Farnell. (and an extra one that I could cut up and use as the two pin power header on the Pi.) My heart was also in my throat. I had used a few different techniques while trying to solder the miracle boards, which also included tape, but the tolerances were too fine and even application of the tape knocked the chip out of line. I would also say be careful soldering the right angle pin header as it seems to melt easily. It's also worth taking a few minutes to tone out the chip pins for continuity. Also, from my questions on the StarDot board, it's not possible to miss any of the resistor packs even if not using the analogue header. I think those are most of my notes so far! I do have some flux pens also. I'm actually still working out what I like and don't. The pens are expensive relative to the paste, but I think my future chip work will be with the pens from now on. Pins and other heavier things will get the paste. No worries about sounding critical. Critical, I can cope with... and is necessary to learn and grow :-) - I'll probably put a parts list in somewhere with all the Farnell numbers. I'll probably actually put it in the description of this video.
@@msknight5 Many thanks for the headsup and also doing this work on video, although the cost may put me off. Despite that its still very useful to watch the learning process as I'll apply it to other repairs that I do. I made myself a headcam mount but I doubt that would be much use when working up close with stuff, e.g. focus and keeping things central to view - I've yet to try it out. As for Elite. Today is the day. I have 6177 kills as of last night and I only need 6400 to cross the threshold. I'll go for a countryside sunset walk this evening, then return to do what I should have done in the 1980's. I say kills, but I realised that even shooting bounty cargo is also classed as a kill, so I've not been selling anything at all. You just become a destroying machine to get to the next "Right on Commander"
@@msknight5 Hi Michelle. I don't know what TH-cam is playing at but I can't find your full response to my last message. All I could read was the summary/bell notification bit: --- "Well, apart from the minimum 10 order on the gerbers, you're not committed to populating all ten of them. The only issue is the minimum order on Farnell and the flash chip I think is the most expen..." --- The rest of the message is very annoyingly missing. Sorry for bothering you, but could you resend the rest please.
@@TheVicar Morning. Fortunately, I don't think it was one of my longer replies so there's not much more apart from possibly some Elite conversation. My reply seems to have vanished completely. Even I can't see it. Anyway, I've started to document the RGBtoHDMI on the msknight.com/bbc pages and I'm documenting the troubleshooting as I go through. Long story short, take extra care when soldering in the chip as the most likely thing to cause problems are badly soldered pins, requiring rework.
@@msknight5 Cheers, I'll follow closely as it should be my next BBC project. I became Elite 2 days ago! After the final kill I turned to cruise slowly back to dock but realised that being a fugitive and carrying some illegal cargo, that I'd better hyperspace to reduce my wanted status - as the docking procedure could be denied and kill me. It was strange going from a full on killing machine to instantly becoming a peaceful tourist. 3 police pinged me in the new system, due to my cargo, but I didn't fire on them and they turned and literally escorted me to the space station where I decided to manually dock. It was an almost serene experience

That was pretty cool! I bet you're still grinning even now :-) ... I've been doing a few things myself... all on the Technilife blog.
