Back
[06:31:44] <Lambda_Aurigae> awfully quiet in here this morning.
[06:31:49] <Lambda_Aurigae> everybody must be sleeping in
[06:31:57] <Lambda_Aurigae> you would think it was a saturday or something.
[06:32:12] <Lambda_Aurigae> heck, I been up for 3 hours and it's only 6:00AM here!
[06:32:17] <Lambda_Aurigae> and I been at work for an hour.
[06:32:21] <Lambda_Aurigae> all by my lonesome.
[06:32:23] <Lambda_Aurigae> it's great
[06:32:26] <Lambda_Aurigae> no sales dweebs
[06:32:29] <Lambda_Aurigae> no phone ringing
[06:32:44] <Lambda_Aurigae> no customers wanting me to replace the toner in their copier because they don't want to get their fingers dirty.
[06:33:11] <Lambda_Aurigae> got more done in the last hour than I did in the last 3 hours of yesterday.
[06:36:28] <sabor> yeah, working in the night is fantastic, especially if you have a few pawns which handle the day work
[06:38:31] <Lambda_Aurigae> well,
[06:38:34] <Lambda_Aurigae> don't have that.
[06:38:45] <Lambda_Aurigae> this is extra overtime trying to catch up setting up new copiers.
[06:38:55] <Lambda_Aurigae> normally we have a spare tech to do this during the week
[06:39:03] <Lambda_Aurigae> but the last week we were down 4 of 8 techs
[06:39:25] <Lambda_Aurigae> and we have been short 1 of 3 analysts for a year.
[06:39:58] <Lambda_Aurigae> so I, an analyst, have been doing tech work this week, along with doing setups and my regular install and computer problem fixing.
[06:39:59] <sabor> sounds like everybody is working for two
[06:40:07] <Lambda_Aurigae> pretty much.
[06:40:16] <Lambda_Aurigae> even our manager has been out doing service calls this week.
[06:40:24] <sabor> woah
[06:40:47] <sabor> a manager doing work, that's something new
[06:40:50] <Lambda_Aurigae> so, today I'm here setting up new machines, getting paid $35.25 an hour for something a barely trained 18 year old screwdriver monkey could be doing at just above minimum wage.
[06:40:57] <Lambda_Aurigae> well, he did come up through the ranks.
[06:41:04] <Lambda_Aurigae> he used to be a copier tech for many years.
[06:41:26] <Lambda_Aurigae> then he was 1/4 owner of the company for 12 years.
[06:41:41] <Lambda_Aurigae> then they sold out to xerox and he became a manager.
[06:42:17] <Lambda_Aurigae> kind of a letdown, going from VP of service for a multimillion dollar company to a mere manager in a multibillion dollar company
[06:42:40] <Lambda_Aurigae> but, he says he makes more money now than he did as a VP, so, I guess it's all good.
[06:42:52] <sabor> hmm, depends on the character, i he's happy with the job it's ok
[06:42:56] <Lambda_Aurigae> and I definitely make more than I started at 8 years ago.
[06:43:16] <Lambda_Aurigae> have just over doubled my salary since I started.
[06:43:31] <sabor> hah, then think about those even higher up doing less and getting more money...
[06:44:14] <sabor> double sounds not bad
[06:44:28] <sabor> but i guess you have a lot more experience than 8 years ago
[06:44:33] <Lambda_Aurigae> yeah..I've gotten some decent raises over the last 8 years...really, over the last 6 years.
[06:44:44] <Lambda_Aurigae> the first two years we were independent and didn't get squat for raises.
[06:44:58] <Lambda_Aurigae> more experience and more expected of me
[06:45:10] <Lambda_Aurigae> went from a lowly copier tech to lead analyst.
[06:45:22] <Lambda_Aurigae> and specialist for 8 models of xerox copiers.
[06:45:22] <sabor> what a change, hehe
[06:45:55] <Lambda_Aurigae> and I'm the only analyst in the company (out of 10 total across us and our sister company) who is on the BEI bonus program.
[06:45:59] <sabor> which size are these models? i guess some bigger machines...
[06:46:13] <Lambda_Aurigae> the ones I'm specialist on is the bw/color office models.
[06:46:41] <Lambda_Aurigae> standalone...wc7845, 7225, 7545, 7125, and others in that line.
[06:46:42] <sabor> at the university we had some big monsters, and very fast, but i forgot the brand...
[06:46:59] <Lambda_Aurigae> we have some big fast ones too that I work on but not the specialist on.
[06:47:04] <Lambda_Aurigae> that's a different class of machine.
[06:47:12] <Lambda_Aurigae> then there are the really big production level ones.
[06:47:20] <Lambda_Aurigae> those take a month of schooling to work on them.
[06:47:40] <sabor> heh
[06:47:44] <Lambda_Aurigae> fastest we do here is 135 page per minute
[06:48:09] <sabor> ooh, more than 2 per second, cool
[06:48:45] <Lambda_Aurigae> igen5 goes up to 150ppm color or bw
[06:49:02] <sabor> wc7845 costs $20k!?
[06:49:09] <sabor> pretty expensive thing
[06:49:12] <Lambda_Aurigae> nuvera goes up to 157 bw
[06:49:18] <Lambda_Aurigae> that's suggested retail
[06:49:28] <Lambda_Aurigae> we sell a 7845 with finisher for around 13K.
[06:50:06] <Lambda_Aurigae> where we make our money is with the ongoing service contracts though.
[06:50:32] <Lambda_Aurigae> they buy a contract that covers parts, labor, and toner and so many pages of black and color a month.
[06:51:10] <Lambda_Aurigae> anything over their quota is at a page price...like $0.005 bw and $0.09 color per page.
[06:51:21] <sabor> yeah, servicing machines is big business everywhere :)
[06:51:35] <Lambda_Aurigae> yup.
[06:51:40] <Lambda_Aurigae> these things are designed to fail
[06:51:42] <Lambda_Aurigae> worse than cars
[06:52:06] <Lambda_Aurigae> they can make copiers that will go a million pages between service calls but you pay for it.
[06:52:32] <sabor> i guess you pay the same either way...
[06:52:33] <Lambda_Aurigae> ok...time to unbox the next one....95ppm bw machine.
[06:53:00] <sabor> happy unboxing :)
[06:53:27] <sabor> i have to continue my panelizing script for kicad...
[07:20:25] <Lambda_Aurigae> breaktime
[07:20:36] <Lambda_Aurigae> D95 and accessories unboxed.
[09:09:14] <yids> does anyone have some tips on fsk demodulating with avrs? basicly my end goal is being able to demodulate stuff that came out of minimodem on an avr. it would be cool if its possible in software.
[09:10:29] <yids> and preferebly not in asembly
[09:10:41] <yids> not sure if thats asking to much
[09:19:37] <yids> actually, i can explain what i want to do maybe someone has some ideas.
[09:21:31] <aczid> I've demodulated ASK/OOK signals
[09:21:47] <aczid> how would fsk work? multiple inputs?
[09:21:53] <yids> I want to make pagers basicly, for now we only made the software that takes care of enrypting the messages doing addressing etc etc, so now its time to start on the actual tranmitting and receivng part. we want to make them using some avr as cheap and easy as possible. first experiments were just with simple 433mhz modules using this RadioHead library. but we are thinking of different ways that can have better r
[09:21:59] <yids> ange/ higher speeds whatever
[09:22:46] <yids> and i was thinking to use fsk for example becuase you could use minimodem with a transmitter connected to it and then demod the fsk signal on an avr
[09:24:10] <yids> but it can basicly be any radio/modulation, we want range and reliablity (as far as you can do that with one way communication) especially, speed is not that important.
[09:35:15] <sabor> yids: this is from the backlog, was posted here a few days ago, it might help you: https://sites.google.com/site/wayneholder/attiny-4-5-9-10-assembly-ide-and-programmer/bell-202-1200-baud-demodulator-in-an-attiny10
[09:37:12] <yids> thanks ill have a look
[10:30:03] <yids> this seems interesting as well https://github.com/mobilinkd/tnc1
[11:35:51] <LeoNerd> http://paste.debian.net/887285/ avrdude getting upset trying to set fuses on a tiny841
[11:35:54] <LeoNerd> Anyone any ideas?
[11:46:11] <Lambda_Aurigae> efuse error?
[11:46:34] <APic> Fuses ♥
[11:46:59] <Lambda_Aurigae> specially when people don't read the datasheet.
[11:47:04] <Lambda_Aurigae> unused bits in the efuse read as 1
[11:47:08] <Lambda_Aurigae> no matter what you write.
[11:47:46] <LeoNerd> The tiny841 doesn't have any unused bits
[11:47:52] <LeoNerd> Also, i wrote 0xFF, and it read back as 0x01
[11:49:30] <Lambda_Aurigae> hmm.
[11:49:33] <Lambda_Aurigae> I see that.
[11:49:42] <Lambda_Aurigae> reading the datasheet now.
[11:52:44] <Lambda_Aurigae> do the other fuses verify properly?
[11:52:51] <Lambda_Aurigae> can you run it manually?
[11:53:52] <LeoNerd> I may have to try each individually yes
[11:54:04] <Lambda_Aurigae> yup.
[11:54:06] <Lambda_Aurigae> I would.
[11:57:03] <LeoNerd> Huh, interesting. I can write either of the other fuses
[11:57:20] <LeoNerd> and if I do, it reads the efuse as 0x01 while it verifies the other
[12:04:24] <Lambda_Aurigae> odd.
[12:04:31] <Lambda_Aurigae> latest and greatest avrdude?
[12:05:15] <Lambda_Aurigae> latest is 6.3
[12:37:40] <LeoNerd> Hrm.. so I've written the other fuses but I'm still having trouble with efuse. It keeps reading 0x01
[15:37:16] <Lambda_Aurigae> LeoNerd, no clue..never used that chip.
