[01:41:11] <rue_bed> mine weighs like 80lbs and has 120 and 240V outputs..
[01:41:23] <rue_bed> its the size of 4 large taosters
[01:44:22] <Casper> mine is only a 500VA
[01:44:57] <Casper> http://www.flickr.com/photos/93694432@N04/11922218025/ <=== my install, don't mind the tools of torture
[01:49:03] <N2TOH> the tools don't bother me as much as the open knife switches
[01:50:50] <Casper> hehe
[01:51:14] <Casper> and strangelly, same with me...
[01:51:27] <Casper> now, imagine in europe.. with 240V on that
[01:51:35] <Casper> in the dark
[01:51:44] <N2TOH> did you install switches to select the different output voltages?
[01:51:56] <Casper> comming in from a raining night...
[01:51:57] <N2TOH> ouch!
[01:52:09] <Casper> those switch are not working
[01:52:38] <N2TOH> we have 240V here too, but for some reason we only use half...
[01:52:49] <Casper> 120/240 you mean?
[01:52:53] <N2TOH> yeah
[01:52:59] <Casper> same as here
[01:53:14] <N2TOH> where are you?
[01:53:25] <Casper> canada
[01:53:36] <N2TOH> oh EH how is the snow?
[01:53:43] <Casper> you mean the ice?
[01:53:59] <Casper> we got lots of snow
[01:54:00] <N2TOH> snow is softer when you fall on it
[01:54:17] <Casper> then we got like -30C + wind
[01:54:30] <N2TOH> F that
[01:54:53] <Casper> -22
[01:54:56] <N2TOH> funny how I was searching for intake heaters
[01:55:13] <Casper> and yesterday we got 7C, with rain
[01:55:36] <Casper> the transition from f***** cold and 7C with rain left tons of freezing rain
[01:56:03] <Casper> saturday was awefull... my car ain'T equipped with ice skate :(
[01:56:17] <N2TOH> http://www.youtube.com/watch?v=SBnOEnlM2JA
[01:56:45] <Casper> why intake heater?
[01:57:00] <N2TOH> diesel powered MTD snow thrower
[01:57:14] <N2TOH> cause glowplugs are not enough
[01:57:35] <Casper> ah diesel
[01:58:06] <N2TOH> there is even a guy who turbocharged a Yanmar clone on his snow machine
[01:59:31] <Casper> yet, our 8hp one probably work better :D
[01:59:44] <N2TOH> 10HP diesel
[02:00:07] <Casper> yeah, try to start one at -20C :D
[02:01:14] <N2TOH> thus the heater in the intake to heat up the air, with a 1000 watt heater
[02:01:29] <N2TOH> it's like aiming a hairdryer into the intake
[02:01:45] <Casper> then... you just lost 2hp in the alternator :D
[02:02:05] <N2TOH> you only run it till the engine warms up
[02:02:40] <Casper> which take half an hour on diesel hehe
[02:03:15] <N2TOH> not in my old VW Passat, damn thing would cool down at stop lights
[02:03:46] <Casper> lol
[02:04:17] <Casper> I forgot who said so, but he have a diesel car too, and his car take half an hour of driving to get heat...
[02:04:18] <N2TOH> I would out later on that car used the same radiator for all engines offered
[02:04:46] <N2TOH> so the 1.9L diesel was mated to a radiator sized for a 2.8L VR6
[02:04:49] <Casper> but are you sure that your thermostat is in good working order?
[02:05:17] <N2TOH> yeah worked much better when I blocked off 90% of it
[02:05:49] <Casper> the thermostat make so an oversized radiator can'T cool down the engine bellow a certain temperature
[02:06:04] <Casper> so you may have a non-working one or one of a too low temperature
[02:06:27] <N2TOH> it was on;y ever a problem in super cold weather
[02:06:28] <Casper> or... your engine make so little heat that the cabin heater cool it
[02:06:44] <N2TOH> car got almost 50MPG
[02:07:46] <N2TOH> http://phillipsandtemro.com//heatingproducts/aih-integrated.asp
[02:08:43] <Casper> I wish diesel was more common here
[02:09:09] <Casper> but at the same time, those with diesel can't start their car when it reached last week cold
[02:09:15] <Casper> oh btw
[02:09:23] <N2TOH> there is a company that sells adapters to install a Mercedes Diesel in a Jeep
[02:09:25] <Casper> my boss was in cuba...
[02:09:38] <Casper> with like 38C
[02:09:48] <Casper> when he came back... it was -30C...
[02:09:51] <Casper> what a shock :D
[02:10:18] <N2TOH> the company making the heaters cold start ability down to -40
[02:12:53] <Casper> my car would start at -40C with no help
[02:15:32] <Casper> now..
[02:15:39] <Casper> what to do when you're hungry at 3am?
[02:15:50] <N2TOH> WHITE CASTLE!
[02:18:07] <Casper> what?
[02:18:44] <Casper> so... I went in the work area... and went to turn off the light... I stretch for the rope... ... ... .. ... oh yeah it's now a switch!
[02:18:46] <Casper> :D
[02:21:34] <N2TOH> There is only one White Castle place in the entire state
[02:23:48] <Casper> that mean.... find it and we find your neighbourhood :D
[02:28:49] <Casper> ahhh that's why my nfs share wasn't mounted...
[02:29:05] * amee2k . o O ( nsfw* share )
[02:29:06] <Casper> somehow it got cleaned out... the nfs-utils package that's it
[02:29:53] * Casper throws a worn out cd at amee2k
[02:30:07] * amee2k nibbles on it
[02:30:16] <amee2k> this does not taste like pizza. *nod*
[02:30:49] <N2TOH> amee2k, what is it with you and pizza?
[02:31:06] <amee2k> i think pizzas taste good? :3
[02:31:22] <amee2k> why, whats the problem with pizzas?
[02:31:26] * amee2k innocently wags tail
[02:31:34] <N2TOH> the carbo coma after you eat it
[02:31:44] <Valen> pizza is like sex, even when its bad, its still pretty good
[02:32:06] <N2TOH> bad movie quotes are still bad movie quotes
[02:32:27] <amee2k> Valen: i'd disagree with that :>
[02:32:50] <amee2k> 99 cent pizzas taste like someone took a piece of cardboard and slapped a cow with it
[02:34:24] <Valen> yuppies
[02:34:36] <Valen> besides, still pretty good is a relative term
[02:35:30] <Casper> cardboard bread, rubber cheeze that still succede to be greasy, sauce that look like dried powder that the cheeze fat liquified, crunchy peperoni....
[02:35:47] <Valen> sounds pretty good to me right now lol
[02:36:03] <Casper> cold
[02:36:13] <Casper> and yes... happened to me...
[02:36:16] <Valen> microwace
[02:36:19] <Valen> microwave
[02:36:28] <Casper> that was an order
[02:36:33] <Casper> delivery
[02:36:44] <Casper> first and last time there
[02:36:53] <Valen> lol, sucky
[02:36:55] <N2TOH> should have used the bum warmer in the seats
[02:37:10] <amee2k> Casper: the tasteless white substance does not qualify as a substitute for proper cheese
[02:37:29] <amee2k> even if i'm too lazy for everything else, i ALWAYS put extra cheese on the cheapo pizzas
[02:37:35] <Valen> I'm needing to run a buttload of piezo elements, they take in 0-50v (basically they are a capacitor) any reconsiderations for amplifiers?
[02:37:52] <Valen> if we are ordering pizza we get them from a good place or dominos
[02:37:58] <amee2k> 74HC/HCT14 ?
[02:38:01] <Casper> fun thing is... the delicio pizza taste better than most restaurant one... and take less times than an order...
[02:38:08] <amee2k> NE555/556/558 ?
[02:38:12] <Valen> I need analog output
[02:38:24] <amee2k> LM324 ?
[02:38:38] <Valen> I'll be feeding a RC network with a PWM
[02:39:22] <Valen> 50 volts
[02:39:47] <amee2k> you need the maximum drive range?
[02:39:57] <amee2k> LM324 can do 36V iirc
[02:39:58] <Valen> probably
[02:41:19] <Valen> I was just wondering if anybody had a pet amp for highish voltages was all
[02:42:34] <Valen> hmm
http://www.newark.com/texas-instruments/lm741cn-nopb/ic-op-amp-1-5mhz-0-5v-s-6mv-dip/dp/41K6294 might do the job, good price too
[02:42:39] <N2TOH> if you have an old VFD display tube you can use it to build and amplifier
[02:43:06] <Valen> commercial product, and i need to do blocks of 144 amplifiers
[02:43:16] <amee2k> if you want a discrete solution, something like the circuit from a 50W audio amp without the main output transistors would probably work
[02:43:42] <amee2k> you'd just need the voltage gain stage, not the output buffer, if you're running only a small capacitive load
[02:44:07] <Valen> I was really hoping to avoid analog design ;->
[02:44:17] <amee2k> other than that, they do make high voltage opamps that can run up to 50-100V
[02:44:31] <Valen> that is what i was looking for
[02:44:49] <RikusW> amee2k: I've seens rs232 drivers used for piezo
[02:44:50] <amee2k> if your signal is 0-5V you'd just configure it as a generic 10x amplifier
[02:44:56] <Casper> those high voltages one are hard to fins
[02:45:06] <RikusW> giving +-12V -> 24V
[02:45:26] <amee2k> http://www.linear.com/product/LTC6090 << prolly an expensive and overkill one, but still
[02:45:45] <RikusW> Old motherboards got GD75232
[02:46:05] <Valen> $8 a pop
[02:46:43] <amee2k> RikusW: mmh, interesting idea actually, but Casper specified analog control (driven from a PWM + LPF DAC)
[02:47:39] <RikusW> 64MHz PWM ?...
[02:47:57] <Valen> PWM freq will probably be ~100khz
[02:48:03] <RikusW> it will need to be a lot higher than 40kHz
[02:48:21] <Valen> why? max output frequency is 300hz
[02:48:21] <RikusW> if thats the piezo frequency
[02:48:25] <Valen> it isnt
[02:48:25] <RikusW> ah
[02:48:41] <Casper> what did I specified?
[02:49:01] <Valen> how awesome i am i think
[02:49:26] * amee2k idly wags tail
[02:49:42] <Casper> oh yeah, but I also said that I was awesommer!
[02:49:56] <Valen> well thtas fair enough i guess
[02:50:12] * Valen thinks amee2k would be better served in a furry chat room
[02:50:46] * amee2k already is in several furry chatrooms :3
[02:51:33] <Casper> of course... you're also in ##electronics :D
[02:52:27] <amee2k> i am? thats new to me...
[02:53:24] <RikusW> its like #avr-offtopic in there :-P
[02:53:34] <amee2k> not really
[02:54:07] <amee2k> the question about the piezo driver involved PWM DAC, presumably from an AVR MCU
[02:54:53] <RikusW> I was referring to ##electronics
[02:54:58] <Valen> the first one will be, the trial with a few pwms, the "real" one will be coming from a FPGA
[02:55:03] <amee2k> oh, i see
[02:55:27] <amee2k> heresy! teh arduino is da master race
[02:55:29] <RikusW> amee2k: you missed the t in there ;)
[02:56:10] <amee2k> lol :P
[02:57:45] <amee2k> Casper: if you want a budget solution, TI LM10C looks cheap and runs off a 45V supply
[03:00:12] <amee2k> OPA551/552 and LM675 runs off +/-30V (i.e. 60 but if you have a single supply, check behavior at the negative rail)
[03:01:35] <amee2k> won't be a problem if AC coupled input is acceptable
[03:02:03] <amee2k> then you can make it self-biasing at 1/2 the supply voltage
[03:02:29] <Casper> the issue I got was with 40VDC
[03:02:40] <Casper> single rail
[03:03:06] <Casper> but I just used a standard opamp, if it die I'll replace it :D
[03:03:37] <amee2k> standard opamps are usually specced for +/-15 or 18V, i.e. 36V max
[03:03:55] <amee2k> but in that case you can use a LM324, they're cheap and easy to get
[03:04:41] <amee2k> and four drivers in a DIP package that can be socketed for easy maintenance
[03:06:27] <Casper> my next psu that I'll make will be an hybrid smps-linear I think
[03:07:00] <Casper> I miscalculated my stuff for the transfo... not enought voltage
[03:07:22] <Casper> so I'll add a boost smps, that shall fix most of the issue
[03:07:57] <amee2k> hehe :)
[03:08:10] <amee2k> why not make a voltage inverter and lower the supply rail a bit?
[03:08:12] <Casper> and it will also use the transformer in a more efficient way
[03:08:34] <amee2k> if you can get +/-30 then you don't need R-R input opamps for your drivers
[03:08:43] <Casper> I may sepic pre regulate
[03:09:09] <Casper> or maybe just invert, who care if it get inverted anyway
[03:09:20] <Casper> brb
[03:09:30] <amee2k> the point of suggesting the inversion is to get a negative rail
[03:15:54] <Casper> the psu will be a triple rail
[03:16:00] <Casper> so no need to make a negative rail
[03:17:02] <Casper> bed time, nite
[05:14:06] <dsaj> can anyone who uses RZ600 tell me what driver do I need to install for my PC to recognize the USB stick?
[06:51:19] <Duality> hi
[07:15:06] <dasj> anyone here use WSN Monitor? how do I suppose to get the COM port on the connect?
[08:47:34] <dasj> is there a room for avr wireless?
[14:11:32] <amee2k> does anyone recognize the brand "Omeg" (for panel-mount potis)? if so, whats the quality like?
[14:15:10] <bss36504> 1133953
[23:30:12] <clixxIO> hello
[23:30:20] <clixxIO> I have an AVR question..
[23:30:43] <clixxIO> I bought a cheapo USB-Nano, I want to load the Arduino bootloader on
[23:30:54] <clixxIO> Arduino-IDE refuses...
[23:31:16] <clixxIO> I'm using an AVR-ISP-II programmer
[23:31:52] <clixxIO> what's the easiest* way?
[23:32:00] <Casper> clixxIO: you need the loader that goes with the right avr
[23:32:14] <Casper> the board name is totally meaningless
[23:32:27] <Casper> the important thing is really the avr chip itself
[23:32:46] <clixxIO> it's an atmega328p apparently
[23:33:16] <Casper> then get the loader for that version
[23:33:33] <clixxIO> I guess so
[23:33:55] <clixxIO> then avrdude?
[23:34:02] <Casper> yup
[23:34:11] <Casper> don't forget to set the bootloader fuses too
[23:35:02] <jacekowski> clixxIO: avrdude
[23:35:17] <clixxIO> yuk - but avrdude hates me
[23:35:46] <clixxIO> anyone know of a good blog set of instructions?
[23:37:03] <jacekowski> google.com
[23:37:13] <jacekowski> and avrdude --help
[23:37:14] <Casper> simple... get the .hex for the mega368p (or code and compile for the mega368p), flash with avrdude, set the bootloader fuses for the right size and reset vector bit to bootloader
[23:37:35] <Casper> ... do we have to set the reset vector... or is that a register... I forgot...
[23:37:44] <clixxIO> ah ok - that's helpful
[23:38:00] <jacekowski> Casper: it's all fuses
[23:38:36] <Casper> it's not hard... it's just that the .hex is not compatible with any other device since each device have it's own register locations and peripherical and all...
[23:39:15] <Casper> then just need to tell the avr which size you reserve for the bootloader, as for it you just uploaded some code somewhere in the flash...
[23:39:32] <clixxIO> somehow I finally found a blog -
http://www.arduino.cc/en/Hacking/MiniBootloader
[23:39:33] <Casper> and tell it to boot off that section instead of the main program...
[23:40:00] <Casper> and this is NOT specific to the arduinono bootloader, but all of the bootloader
[23:41:00] <clixxIO> ok thanks - I will try tonight
[23:41:42] <Casper> hmmm I so don't think I can put that breaker in the box... grrrrr....
