[01:22:15] <katsmeow> ...
[01:22:56] <rue_house> going to sleep
[01:23:05] <rue_house> while trying to design a dip8 H bridge
[01:23:18] <rue_house> around SOT23 transistors
[01:24:28] <katsmeow> how much current?
[01:24:35] <katsmeow> what switch freq?
[01:24:39] <rue_house> 2A, I'm gonna use the sot23 fets
[01:24:48] <katsmeow> ans: use a LM386
[01:24:53] <rue_house> I been over it for a week with options
[01:24:54] <rue_house> no
[01:24:56] <katsmeow> ok
[01:24:58] <rue_house> too much votlage drop
[01:25:06] <katsmeow> true
[01:25:07] <rue_house> only about 0.7V max bridge drop is ok
[01:25:40] <rue_house> with these fets I have about 0.4
[01:25:44] <katsmeow> use to-92 fets, let them hover above the driver chip where the airflow is better?
[01:25:50] <rue_house> cant, they dont exist
[01:25:54] <katsmeow> oh
[01:26:01] <rue_house> not in 13mR
[01:26:20] <rue_house> they just do not put good fets in to-92
[01:26:26] <rue_house> I dont know why
[01:26:40] <rue_house> thts why I soldered those ones to the to-92's
[01:27:14] <katsmeow> ok, why didn't you smd them?

[01:27:35] <rue_house> breadboard
[01:28:10] <katsmeow> yeas, saw yesterday
[01:28:28] <katsmeow> how will you drive the fets?
[01:28:35] <rue_house> nor is there a dip8 with 4 of those in it
[01:28:44] <rue_house> 18V rail-rail
[01:28:48] <rue_house> the motor votage is 6
[01:28:58] <rue_house> all N channel
[01:29:02] <rue_house> it works out
[01:29:15] <katsmeow> cannot be a dip 8 with 4 of them, that's 12 pins

[01:29:36] <The_Jester> thoughts?
[01:29:47] <katsmeow> orange juice
[01:30:20] <katsmeow> inductor hidden on the backside?
[01:31:16] <katsmeow> you blew the efficency if that diode is in series with the power

[01:32:03] <rue_house> adjustable, filtered, and everything
[01:32:26] <rue_house> and I have a few in stock
[01:32:36] <rue_house> gngiht
[01:33:33] <katsmeow> Shipping:US $2.29to United States via ePacket
[01:34:19] <rue_house> why not use free shipping?
[01:35:15] <rue_bed> the shipping timeis a lie to cover their ass and avoid bad feedback
[01:35:53] <The_Jester> that might be a good solution, any luck i still have a 7805 in the drawers
[01:35:54] <katsmeow> k
[01:52:25] <rue_bed> they are good for 1A
[01:52:54] <rue_bed> 3.4V drop, so 3.4w power loss at 1A
[01:53:22] <katsmeow> ouch
[01:53:54] <katsmeow> TIP31 drops 0.2v saturated at 1amp , iirc
[01:54:27] <katsmeow> tip102-107 drops only 1.3v at 1amp
[01:58:17] <rue_bed> the bottom fet is .107V
[02:01:20] <katsmeow> the bipolar still beats the 7805 tho
[14:36:47] <katsmeow> pingles
[14:59:45] <katsmeow> ...
[15:14:39] <katsmeow> so 44v on a 174,800 ufd cap, putting a 0.7 ohm resister across it for 4ms, the cap will discharge only 1.4v
[15:15:01] <katsmeow> 60amps
[18:57:31] <rue_house> wonder if that includes plate resistance
[19:03:10] <Tom_itx> neighbor got robbed today in broad daylight
[19:03:27] <Tom_itx> we were standing in the yard mowing right in front of em
[19:03:53] <Tom_itx> she probably owed them money
[19:13:12] <rue_shop3> er, did the robbers get caught then?
[20:03:33] <Tom_itx> not yet
[21:34:55] <katsmeow> Tiggr is so polite because....
[21:35:11] <katsmeow> she is made with integracious circuits
[21:40:45] <Tom_itx> kat did a funny :)
[21:42:33] <katsmeow> heys Tom
[21:48:09] <katsmeow> what does anyone use a 74HC4053 for? it's a 3p3t analog switch
[22:17:38] <rue_house> 3 source trinario audio switch?
[22:18:00] <katsmeow> i have only 2 ears in this body
[22:19:46] <rue_house> hmm, this months gas bill is -$9.86
[22:20:31] <rue_house> its due by sept 8, I wonder if they will acrew interest if I dont pay it
[22:20:52] <katsmeow> no, but they'll turn you over to collections for it
[22:20:57] <katsmeow> just watch
[22:21:14] <rue_house> the cost of gas used was $0.91
[22:22:03] <rue_house> I'm gonna install a solar array, see if I can turn the hydro bill around
[22:22:39] <katsmeow> i'm interested in how you will turn sunlight into water
[22:22:43] <rue_house> I wonder if I can send a cheque for a negitive amount...
[22:23:03] <rue_house> we call electricity hydro here becasue its all generated by waterfalls
[22:23:08] <katsmeow> o
[22:23:35] <rue_house> well, hydroelectric, we dont bother with that big complicated last part
[22:23:38] <rue_house> :)
[22:41:28] * katsmeow is feeling daring, and wants to see what happens if she curls up again in the nestbox with it's warm footroaster
[22:42:44] <rue_house> katsmeow-afk, water at 70c vs 80c
[22:42:55] <rue_house> would you say there is much of a difference in density?
