Nope, but i did lay them one atop the other when cut to see if they were close enough

well as long as they are not glass or ceramic platters (usually only found in higher spec drives) they will most likely be aluminium in which case they'll never shatter if you do find yourself with a glass or ceramic platter i guess a fine diamond dust cutting wheel might do it if your very careful ...

a couple of videos for you... normal ruinning mode, sorry about the flickering, it's the mismatch in camera shutter speed and refresh speed of the POV clock, much like when you try to video a tv and get black bars. http://www.youtube.com/watch?v=VICIvcE9U_0 http://www.youtube.com/watch?v=NV5Zj8m4e18...

Gosh i feel so stupid :oops: i spent nearly an hours yesterday trying to track down a problem with my code, when in 'time set mode' the hours should first blink, and then when you press the set button again the minutes should blink, and finally when you press the set button again the new time is wri...

i cut the platters with a dremmel, the vibration is very smal as long as you get the slots opposite each other, they counter balance each other :D but one thing whne selecting a hard drive.... i found that after ripping out the heads and voice coil that after a while maybe 30 seconds or so the spind...

Well that was a nightmare... decided as my code was growing to split the source up into modules... and added a few tweaks along the way, i think that was my downfall, i should have just split it and re-tested it before doing the tweaks. my i2c bit banger is ugly as heck, it was nice and readable ful...

i originally posted something along the lines of zx81 was my first ever computer and i loved it, came complete with wobbly rampack

that was before i remebered the password to this account, which the email address registered against it i had no longer access to...

ah ah... it's not that i particularly want it to go faster, i write code in a very haphazardous way, commenting out sections and putting in new bits, then when i am happy with the results i sit down and tidy it up, add more comments to make it easier to understand what is going on and delete all the...

Well it works, i can tune it off and come back to it some time later load up the program and have the correct time displayed :D still tweaking the code before i start adding extra display modes (when i can tihink of them) first bit of code that i'm trying to optimise is this BCD_TO_A LD D,A ;SAVE TH...

:lol: i like the phrase misusuing the zeddy, it's a development tool ;) yeah i could go down the road of buying more kit, arduino, propeller, pic, ect... there's a few to choose from but why bother when i am happy with Z80, already know it's language and some of it's tricks ;) would be like riding u...
