12:00 AM rue_mohr: something that requires less than 18 supply voltages and comes in a narrow dip is preffered
12:06 AM MrMobius: the newer CMOS equivalent
12:06 AM MrMobius: that is wide dip though
12:06 AM rue_mohr: there isn't?
12:06 AM MrMobius: well its not that tiny
12:06 AM rue_mohr: I mean, I can strap a battery to a ram chip and tie the R/W high...
12:06 AM rue_mohr: hahahah
12:06 AM rue_mohr: SHIP IT!
12:06 AM rue_mohr: (I'm surprised its not been done yet)
12:06 AM MrMobius: 8k = 64kbit is the smallest you can get in the new ones
12:06 AM MrMobius: hehe, of course they have done that
12:06 AM MrMobius: the dip packages were extra thick for the integrated battery
12:06 AM rue_mohr: MrMobius, do you know of a Narrow 8k?
12:08 AM rue_mohr: everything I do is one-off
12:08 AM rue_mohr: hahaha
12:08 AM rue_mohr: china sells 28C16 for less than 16V8
12:09 AM rue_mohr: not the same I know, but halarious
12:10 AM MrMobius: heh you hope its a 28C16
12:10 AM MrMobius: I wouldnt count on it
12:10 AM rue_mohr: for that price?
12:10 AM MrMobius: no just because its china
12:11 AM MrMobius: someone on here bought an EEPROM and couldnt get it to work for anything
12:11 AM rue_mohr: yea I got some of those
12:11 AM rue_mohr: geniune pullouts here
12:11 AM MrMobius: after days of stress they scraped off the markings and it was a 68008 processor
12:11 AM rue_mohr: I programmed em bad
12:11 AM rue_mohr: hahaha
12:11 AM rue_mohr: bonus!
12:11 AM rue_mohr: thats never happened to me
12:11 AM rue_mohr: I'v been sold obvious D grade stuff tho
12:12 AM MrMobius: its like playing the lotto
12:12 AM rue_mohr: if you want garuntees, pay for it
12:12 AM MrMobius: I got some 74HC590s iirc from china and they may never actually have existed in HC
12:12 AM rue_mohr: I'v not had problems and if I do, I'll eat it
12:12 AM rue_mohr: ls is nice, no pullups req'd
12:13 AM MrMobius: thats irrelevant if you bought HC bc your circuit is 3v :P
12:13 AM rue_mohr: heh
12:13 AM rue_mohr: *3v, chuckle chuckle*
12:14 AM rue_mohr: hmm
12:14 AM rue_mohr: well I have hundreds of eproms
12:15 AM rue_mohr: if I cant get anything narrow
12:15 AM rue_mohr: hmm
12:15 AM rue_mohr: next issue
12:15 AM rue_mohr: how do I get a 4017 to self-oscillate....
12:16 AM MrMobius: as long as y ou have a beefy power supply :P
12:16 AM MrMobius: I kept getting brownouts and eventually figured out the old eeprom I had thrown on there was sucking down 250ma
12:17 AM rue_mohr: wow
12:17 AM rue_mohr: must have been burning hot
12:18 AM rue_mohr: wait I think I have an LC oscillator that will run off a 2803 gate
12:18 AM rue_mohr: I'm using two uln2003 right now, I can just upgrade one
12:20 AM rue_mohr: gnight
12:20 AM MrMobius: cya
04:33 AM vmt: rue_mohr: no i'm not, but wouldn't that be a great "one-chip solution" as well?
11:20 AM lvlinux is now known as ruel
02:05 PM ruel is now known as lvlinux
11:38 PM rue_shop1: no it wouldn't
11:39 PM rue_shop1: The avr digital inputs, powered from 5V, are symmetric for a 3V supply
11:52 PM rue_shop1: heh
11:53 PM rue_shop1: what in parallel with 150k is about 10k
11:56 PM rue_shop1: it looks like about 10k
