  1. Did you hear about the three nuns taking a shortcut though the park last night... when a man in a heavy overcoat jumped out and flashed them? Two had a stroke.,.. but the third couldn't reach
  2. You could do it in one shot with a single use form-over mold. Make it out of styrofoam and then chip and dissolve it after laying up the fibre. Hardest part would be getting the surface finish silky smooth...
  3. That looks great. Is there a bit of forced perspective on the fire station? You are right though, it is a much better fit and the visibility is heaps better.
  4. No problem. If you are missing anything from the kit or need more info, let me know. I still have a few sets hanging around.
  5. Yeah I know, I was surprised when I saw the date on the boards. Things have changed ... I was paying over $200 for a 5m roll of red LED tape back then, now you can get led tape for less than ten bucks...
  6. I know what it is. I designed and made it. It is the controller PCB for the Indiana Jones Path of Adventure lighting kit.
  7. I went last year as I thought it had been ages since I did anything related to pinball. I had a great time, and it set a fire under me to get in the room and fix something... I had 5 machines - all not working at that time. I ended up with 3 working now, and solid plans for those last 2. I wanted to offer to bring my AG Soccer-ball for 2 reasons... one was it isn't a machine many get to get their mitts on, and two was to finally get it all together and reliable again, as it was a solid goal with no way to wimp out. I had the most fun from that machine over the weekend just seeing it get played... played and enjoyed. The audits showed 297 games over the weekend - probably more than it had in the ...considerable... number of years I owned it. Out of practicality reasons (I just could not make it fit in my space being a head to head machine) I had it for sale there, and while it was hard to see it go, I am also happy to see it head off and be appreciated somewhere else... I did not play anywhere near as much as I would have liked - unfortunately real life was in the way of being able to come to the contributor sessions, but next year I am hoping to have better plans in place. Not that it mattered too much at all, I spent a lot of the time just talking to people. I'm also hoping to be able to have one of my currently down machines primed and ready to contribute next year! I gladly paid for tickets to bring my kids and Mrs to a Sat session, as well as to drag a mate on the Sunday one. I really appreciate all the effort that went into organising the event - to make it feel so easy and well oiled takes a huge effort behind the scenes. I also want to thank everyone who put in the effort to drag in a machine, and trust the public with them. After doing it myself I see why you lot go through all that effort.
  8. Since getting a decent scope, this poor guy has sat on my shelf unused... Time to move it on. Dick Smith Electronics K-7337 assembled by me a long time ago. I will re-calibrate it before shipping - although it isn't a high performance device with 4 digit display. I will throw in a probe to go with it. It needs a power supply of ac or dc 7.5v to 12v (it has an internal 5v regulator supply) - i used to just use the bench supply for it. Happy for a beer + postage. what does a beer go for at the pub these days? Call it $5? SIideways pic because lazy:
  9. Sure, it could be OK. If you are basically just wanting a glorified logic probe, where you are checking if pins are toggling etc and comparing levels, looking for noise. You can certainly use a 10mhz scope for a lot of that stuff, especially on older boards that have lower clock speeds than modern ones - as this was pretty much the tech at hand at the time. I sold my old scope for $35 about 10 years ago if that helps you get your head around the price for one of those "boat anchors" 😄 Finally, if you are wanting an analog scope for the cool factor, then just get one! If all else fails you can just hook it up to the stereo and use it as a visualizer 🙂
  10. with an analog scope, be careful regarding the bandwidth. The higher you try and measure, the dimmer the trace will be. 5mhz will be hard to see, and 10mhz will be guesses. So with that in mindm you want to aim your analog scope bandwidth around 2x higher than the kind of signals you want to measure. I started with that exact scope pictured there - and got frustrated very quickly with it trying to work with digital stuff. If you can get your hands on a cheap digital scope, like a Rigol 50 of 100mhz model you can get all your bases covered. Neat things with the DSO are on screen measurements of voltages, frequencies and stuff, and even a memory for trace capture. Cost more, but get more functionality - may be worth seeing what is out there 2nd hand too.
  11. fair enough. The sound one is newer though. I might as well just read them and actually check if they are different...
  12. @wiredougthanks, I found that set and it has the same versions in the other sets I found floating around. So it looks like 2 of my roms are versions not really "out there". cheers
