04:59 AM Tom_L: need more clay powder?
11:55 AM rue_mohr: yes, not quite enough yet
12:01 PM Tom_L: does it take like half a bag or more?
12:01 PM rue_mohr: 30%
12:01 PM Tom_L: and you can get more than one casting from it?
12:01 PM rue_mohr: and the pulley is a big mold
12:01 PM rue_mohr: the pulley uses my second largest mold
12:02 PM rue_mohr: not sure how much sand that is
01:47 PM rue_mohr: ok, well
01:47 PM rue_mohr: I'v come to the conclusion I can always fill breadboards
01:47 PM rue_mohr: I got 2 big orders of breadboards and I only have a few left
01:48 PM rue_mohr: but there are projects everywhere on breadboards
04:16 PM Tom_L: you still keep them after testing em?
04:59 PM polprog: rue_mohr: what emitter follower?
05:31 PM rue_mohr: hu?
06:00 PM polprog: you hilighted me yesterday
06:01 PM polprog: 10:47 < rue_mohr> polprog, see how using an emitter follower like that doesn't offend anyone? the current is sunk by pin 3, thats behind the 10k resistor
07:55 PM rue_mohr: ok, its regarding the voltage clamp on the 555
07:56 PM rue_mohr: it doesn't short and signals
08:29 PM rue_shop3: polprog,
08:29 PM rue_shop3: you there?
08:29 PM rue_shop3: Tom_L, ?
08:59 PM Tom_L: huh
09:12 PM rue_mohr: so I'm pondering a web databse
09:13 PM rue_mohr: you know how you can search dk by param
10:26 PM rue_mohr: I'v started (again) a list of the specs for the transistors I have
10:26 PM rue_mohr: I'm just using a spreadsheet
10:27 PM rue_mohr: but if I could have soemthing like dk where I can enter ranges and build a filter, it would be awesome
10:27 PM rue_mohr: I could gradually build it up
10:27 PM rue_mohr: make for less time searching for the right part
10:28 PM rue_mohr: it took me about 2 hours today to find an npn transistor that could take 80V at 1A and had a gain of more than 5
