#garfield Calendar


01:32 TELunus Sound's like if I do well, and if the company gets more funding (which I guess are not even that unrelated, it's a tiny company with 2 actual employees besides students on UBC projects), it could be a job opportunity.
02:16 rue_house yes, I know a fellow who got his job just like that
02:33 rue_bed http://www.aliexpress.com/item/3M-8-1-Timing-belt-pulleys-timing-pulley-timing-belt-belt-pulley-the-suite-of-Synchronous/1233196088.html?return=http://www.aliexpress.com/item/3M-8-1-Timing-belt-pulleys-timing-pulley-timing-belt-belt-pulley-the-suite-of-Synchronous/1233196088.html

08:55 katsmeow-afk rue , the original bipolar-only in basic 1-phase : http://designerthinking.com/DSCF3540m.jpg
08:56 katsmeow-afk i changed to mosfets and negative-line switching to get around the p-channel issue, and lost the diode block to get around that 1.6v of drop
08:56 rue_house hmm
08:57 katsmeow-afk that one doesn't do capacitor voltage forced-equalisation either
08:58 katsmeow-afk but it is the simplest, especially for 2-phase
08:59 katsmeow-afk 4 pnp power, like TIP42 or TIP36 , one fwb diode block, and the 4 lil pulldown transistors, 3 capacitors
09:01 katsmeow-afk you see my note about the fet vs bipolar at 7amp, below 7a the fets win, and at higher freqs the bipolar wins,, it's one of thos conundrums you can fall into
09:02 katsmeow-afk note the top cap will always run about 1.5v higher than the bottom cap if all bipolars/diodes are used
09:04 katsmeow-afk there's some 15v@8amp pwr supplies on ebay now for $11 (free s&h) , this switcher should make it into 6v@16a for running small motors, like servoes, gobs of servoes and their drivers
09:10 katsmeow-afk using the fet circuit should make 7.xv tho, so you can charge the 6v batteries up to 7v
09:14 katsmeow-afk so,, these are all the same : DaledGroup ; thebatteryconnection ; ebaybatteries.com ; Battery Gallery ; inkcredibleprinting (ebay id)
09:16 katsmeow-afk http://www.pissedconsumer.com/reviews-by-company/ebay/battery-rip-off-on-ebay-thebatteryconnection-20110108215398.html
09:19 katsmeow-afk it's been almost two weeks now and still nothing I've contacted the seller but he wouldn't respond I also contacted eBay about thus and they said since it's there 3 year warranty they can't do nothing about it:/
09:20 katsmeow-afk Our warranty does not cover wear and tear, it only covers physical defects such as the battery cracking, or the casing opening up and the such.
09:23 rue_house you bought a battery and it didnt' show?
09:23 katsmeow-afk wasn't me
09:23 katsmeow-afk http://www.ecommercebytes.com/cab/abn/y12/m12/i18/s01 Underwriters Laboratories Warns of Counterfeit Batteries on eBay
09:23 katsmeow-afk UL said the counterfeit battery was being sold by a Top Rated seller on eBay who has 687,325 feedback who goes by the name of thebatteryconnection. We were unable to contact the seller, and eBay did not get back to us by press time.
09:24 rue_house is their feedback under 90%?
09:25 katsmeow-afk i didn't look, i figured you might be interested because you might be buying batetries
09:25 tsmeow-afk was interested in their http://www.ebay.com/itm/390543160189
09:25 rue_house do you know how many things on ebay UL could say that about?
09:26 katsmeow-afk however, that charger seems to be the one that burns up in an hour, like the 12v@1a charger i got from somewhere else
09:26 katsmeow-afk no
09:26 rue_house yo utried it?
09:26 katsmeow-afk no
09:27 rue_house well I found the CORRECT fuel tap for my truck
09:27 rue_house buy it on ebay this time
09:27 tsmeow-afk
09:27 tsmeow-afk needs to go back outside and do more th
09:27 katsmeow-afk bbl
10:23 katsmeow-afk it's all sweaty outside
19:24 rue_house kat, you decided on payment?
19:24 rue_house a money order is as good as cash
19:25 rue_house at a bank anyhow
19:46 Tom_itx hyperterm foiled again
19:51 katsmeow-afk [20:57] * katsmeow-afk will let you decide, if you wish to send money via pp instead of keeping me informed
19:51 katsmeow-afk [20:58] * katsmeow-afk is sad you'd rather send money than keep her informed, but that's the way shit falls
19:51 katsmeow-afk .. 9 pm Tuesday 9/10/2013 ..
19:52 katsmeow-afk and since you do not want to keep me informed, why am i in here?
20:08 rue_house heh, she did it afgain didnt she/?
20:12 Tom_itx rue_house, you ever use realterm?
20:13 Tom_itx trying to figure out if i can save the setup settings on it
20:21 rue_house for serial?
20:21 rue_house use putty
20:22 Tom_itx not for this
20:22 Tom_itx it's to communicate with a large cnc
20:23 rue_house use puty
20:24 Tom_itx is it easy to add delay with putty?
20:24 Tom_itx this is an old machine and needs slow serial
20:24 Tom_itx hyperterm quit working for him so i went and installed realterm to get him goin
20:26 Tom_itx can't see that putty will do that
21:33 Tom_itx looks like i can set the parameters from a cmd line
21:33 Tom_itx aka batch file
21:54 rue_shop2 what do you mean delay?
21:56 Tom_itx ms delay between characters
21:57 Tom_itx the control throws a frameing error if i send em too fast
21:57 rue_shop2 its old and it dosn't have hardware handshaking./
21:57 rue_shop2 ?
21:57 Tom_itx i don't think so
21:57 Tom_itx the pins are jumpered to fake it
21:57 Tom_itx 4800 baud sir
21:58 Tom_itx they don't make the control any more
21:58 Tom_itx but it still works so...
21:58 Tom_itx i got a batch file setting most of the parameters now
21:59 Tom_itx no cmd line option for setting software flow control
21:59 Tom_itx i'm gonna try it without it and see if it works
22:00 Tom_itx if not, he can check that in the terminal when it comes up
22:13 rue_shop2 why not unjumper the pins and not fake it, then it'll work right...
22:13 Tom_itx i don't think the control supports it
22:14 rue_shop2 if its old, it'll do hardware handshaking
22:14 rue_shop2 software dosn't have to support hardware handshaking, its done by the hardware
22:14 Tom_itx i'm not gonna rewire it now
23:38 rue_house woos
23:53 lolina8088 bam
23:56 rue_house sorry, phone call
23:59 rue_house so I got kat to find some parts for me from china
23:59 rue_house oh he's a talker
23:59 rue_house ...
