hmmm... I really wish this is it... but, it definitely looks right... (it looks like here http://www.ucapps.de/mbhp_core.html)... the metal thing is on the side facing the little bridge, the resistor and J4... ??? ...do you think I should solder it the other way round? edit: being the impatient lad I am, I tried soldering it the other way around... I got the exact same measurments... hmmmm... doesn't sound bright...

:) hehe... ok... no prob... I went for the pump... and it worked like a charm... the core module is fully soldered... BUT... for testing purposes, I used a wall adapter to power only the core. It's a 9V/1A one (I use it for a Boss stomp-box), so, I guessed it would be fine. well.... it wasn't... the wall adapter's output showed something like 8.5V on the multi-meter, but I was getting only 1.1-1.2V everywhere on the core, plus the 7805 was getting too warm (being plugged for less than a minute, and touching it for a single moment almost got me a nice burn). any suggestions? ??? ps: I should probably check for short-circuits, since the core actually came up rather messier than the DIN... :-\ ...is there any chance that a short would 'cause what I'm describing? edit: I also tried with a 12V/1A adapter (being ultra fast, to avoid burning the 7805), and it still gave me 1.1-1.2V

moebius: what's a soldering tap supposed to be? (I can sense a weird joke in the air... but I thought I should still ask...) ...and what's with the capital Ys? ::) thanks anyway, people... :) although, the rest of the day was a disaster... I started working on the SID module, mixed some capacitors, misplaced them, desoldered them without a pump/braid, had solder spread all over the place... and on top of that, I managed to break off the corner of the core pcb... (don't ask me how :-[). I think that I got it back together succesfully though... (and I also think I'm an idiot...) as far as the PSU goes... I think I'll follow your advice, and if all else fails, ask for tarzan boy's help (thanks in advance! :)) I'm off to buy a pump... or braid... I don't know... cheers!

Hello there! this is Dinos, hailing from Athens, Greece... :) ...so, I found this beatiful community, spent lot's of time reading the wiki, the forum, and ucapps.de... I ordered everything I needed (from Mike's shop) for a simple monophonic, MBSID (also, using a 2x20 LCD, some buttons and an encoder, as a control surface). I must admit that I had never, ever soldered a single joint in my life, so... this whole project is a challenging task for yours truly. I got access to a probably malfunctioning C64 (no PSU... so, I couldn't even test the SID chip...), and cannibalized an 8580 chip. Last Saturday, I started soldering the DIN module (it seemed ideal as a starting/experimenting point, since, even if I completely ruined it, I would be able to get sound out of my MBSID... I would just be left without a control surface). I think that I made it... :) (I don't have a way to test it at this point, though...) The next step was the CORE module, which I started soldering today... this is what my messy desk looked like before starting working Well... problem is, that I messed the bridge rectifier placement, soldering it a little bit on the right hand side of where it was supposed to be... :-[, and lacking a desoldering pump, or something, I just stopped working on it until I get to buy one... I will keep everyone updated... :) cheers! (wish me luck!) (sidenote: as I said, I actually DON'T HAVE a C64 PSU, so, I'll have to figure a way out to power my thing... I've spent some time reading all relevant threads, feeling lost in subjects I have inadequate knowledge of, but I'm confident I'll work this out... :))
