@NickHalden We could make a question on how to port it.

Nick Halden

@Kortuk Ooooh good call. Isn't there even a way to ask a question and answer it yourself? Then I could get points for both the question and the answer!

Kortuk

@NickHalden there is, it just can be hard to make a good question.

Anindo Ghosh

I would love to stay and chat further about it, but the wife's feeling a bit under the weather, so I gotta go. Sorry. Bye all!

Nick Halden

@AnindoGhosh damn, good luck ttyl

Kortuk

@AnindoGhosh Tell her to feel better!

@NickHalden But you might want to prep the writeup.

@angelatlarge remember where you found the ISPIC? (That was you, right?) I can't find it so fast

Nick Halden

@Kortuk okay, look for that sometime in the next ~10 days or so... ill be fairly busy until next weekend so probably around then...

angelatlarge

@CamilStaps I didn't find it. @jippie found things kind of like it, but you'll have to design it yourself :)

Kortuk

@NickHalden No worries, no rush.

I am not going to be here all weekend, I am doing a crawl for cancer.

angelatlarge

@CamilStaps What @jippie wasn't ISPICs (I think)

user61389

@angelatlarge ah but I found this at least. No schematic, but it has code, so I can figure out the pins I think

angelatlarge

19:07

@CamilStaps Ah, well, thats an ISPIC!

@CamilStaps No PIC code for that? Are you sure? That would be weird for something published on hack-a-day

user61389

@angelatlarge nice! I found it :) I think I misunderstood you guys before, I thought there was a project called ISPIC

user61389

@angelatlarge no schematic, but code, on the github repository that's linked to

angelatlarge

@CamilStaps No, I was proposing that you should design something like that.

@CamilStaps And this project is it. Yes, I saw the code.

user61389

@angelatlarge oh yeah now I remember!

user61389

By the way, is it true that avrdude says things like 'Yikes'?

angelatlarge

19:10

@CamilStaps Yes. avrdude is chatty. It always says "Thank you" afterwards too

user61389

@angelatlarge hmm, that will get annoying :)

angelatlarge

@CamilStaps You don't notice it after a few times. Your eyes are just drawn to the important stuff.

user61389

@angelatlarge I hope so

angelatlarge

@CamilStaps I don't see the schematic, but it looks like the author is using a dev board, that's probably why.

user61389

@angelatlarge I see, but they can at least tell what pins they're using, right? Anyway, it won't be too hard to find out

angelatlarge

19:13

@CamilStaps It shouldn't be too hard though: the ISP standard is well described (the author actually has the PDF in the repository), so figuring out what you need hardware-wise shouldn't be hard.

@CamilStaps yeah

user61389

@angelatlarge yes, saw the docs already

angelatlarge

@CamilStaps Basically, ISP is SPI plus holding the reset pin low. That's it.

user61389

It probably isn't very much external circuitry, if any

user61389

SPI has a CS pin, isn't that similar?

angelatlarge

@CamilStaps If you build a dedicated circuit I do have one suggestion: add a jumper for whether the programmer powers the AVR or not.

@CamilStaps Hmmm.. I never thought about it this way, but yes.

user61389

19:15

@angelatlarge good idea. I'll see what features my PIC programmer has and try to do the same with this, because yes, I want a dedicated circuit

angelatlarge

Take a look at this project, it is extremely well documented and the schematics are published, and copy the hardware: ladyada.net/make/usbtinyisp

@CamilStaps (with suitable PIC-related modifications)

@CamilStaps Actually, one thing I would add to USBtinyISP is an extra LED indicating whether the programmer will provide power to the AVR or not. I would like to have that feature on mine. Alas.

@CamilStaps But the "on" and "programming" LEDs are nice. I would have that on yours if you can.

user61389

Nice ideas. I might consider making this for the dedicated circuit instead; this has a USB interface.

angelatlarge

@CamilStaps Cool

user61389

The ISPIC's todos contain USB support, but the last commit was 3 years ago :)

user61389

Guy's like me.

ManishEarth

19:47

Arduino questions ought to come in in a few hours. I think

user61389

@ManishEarth do you know how many?

ManishEarth

All of them

almost

Kortuk

@CamilStaps ~70-80

ManishEarth

~85

Kortuk

ohh, higher then I thought, I thought there were other migrations

interesting.

ManishEarth

19:49

@Kortuk total is 91 right now, and then there are like 6-8 other migrations

user61389

Okay, glad I'm sleeping by then :)

Kortuk

@CamilStaps They wont dump on front page, they will just silently insert in the site.

ManishEarth

@CamilStaps leave your EE tab open, when there was a mass migrate to physics it was a treat to watch

user61389

@Kortuk oh, okay

ManishEarth

@Kortuk Whoever is viewing the page will get a flood of realtime updates which will disappear on reload

Kortuk

19:50

@ManishEarth awesome!

ManishEarth

or something like that

WATCH 'EM ROLL IN!

in The h Bar, May 4 '12 at 20:32, by Shog9

real-time updates make this sorta fun

Q: The main page acting strange and inconsistently

Right now (May 4th '12 20:58 UTC), the main page either remains as I first opened it or continues to 'update' with tens of questions each second coming to the top of the list. Once I refresh, it's gone and everything is back to how it was when I first opened it; a minute later and the same behavi...

@Kortuk @CamilStaps

"Over a thousand questions" <-- whoa, did not know it was that many

user61389

Nice. Makes me wonder, how should we go about retagging?

ManishEarth

@CamilStaps no need to

I already took care of that

user61389

@ManishEarth okay, nice, thanks :)

Kortuk

@CamilStaps They did it already, should be pretty good.

ManishEarth

19:56

Basically I and a few others retagged the post on Arduino to follow the EE.SE tag system

user61389

So I can't have my edit badge by tomorrow :(

ManishEarth

See, retagging the posts when on EE would be slow as you can't do too many lest you flood the main page (>5 at a time is bad)

user61389

@ManishEarth thanks a lot for that!

Kortuk

@CamilStaps yeah, a whole bunch of edits bump the front page too much, but on a dieing site it is fine.

ManishEarth

@CamilStaps retags don't get you the edit badges

user61389

19:57

@Kortuk I totally understand

ManishEarth

Since Arduino was going down the drain anyway, we defaces its main page by retagging at full speed

(It helped that I had the 10k inline retagging tool)

user61389

@ManishEarth oh really? That explains why Brian Carlton has >500 edits but not the badge, I guess

ManishEarth

@CamilStaps yep

A: What do you need to know about the upcoming mass migration?

How will the migration happen? On Friday (barring any unexpected delays), the Stack Exchange team will take the Theoretical Physics and Astronomy sites offline, and will transfer all remaining questions except for closed questions on them to Physics. The transfer will be done in a similar manner...

user61389

Ah, by the time I wake up everything will be perfectly normal, I guess, but thanks

ManishEarth

yep

though suddenly i'll have lots of EE reps

user61389

20:01

@ManishEarth which you probably wouldn't have gotten if the questions would've been here from the start :P

user61389

But yes, that's fair of course

ManishEarth

@CamilStaps yeah, but I wouldn't have participated here

due to a time issue

not due to an attitude issue

I wanted to try and help Ar.SE succeed, so I devoted some time to it

user61389

@ManishEarth what time issue? Ah, I see

ManishEarth

@CamilStaps not that much time. I moderate two sites and I'm active on a few more

Plus I must study some time, right :)

user61389

@ManishEarth yes, I've seen you on quite a lot more sites indeed

ManishEarth

20:03

There are tons of sites that I'd like to get active on, no time :P

@CamilStaps probably more on metas. I've seen you on MSO and RE meta

user61389

@ManishEarth yep, I remember you of metaso, and Area 51, not?

ManishEarth

oh yeah a51 as well

user61389

Anyway, I have to go. See you!

ManishEarth

cya :)

@angelatlarge refresh the main page, that will disappear

in Arduino, 8 mins ago, by Shog9

heads-up: about to migrate just about everything from Arduino to EE

angelatlarge

@ManishEarth Yes, I've been paying attention to the chat.

ManishEarth

ah

angelatlarge

@ManishEarth Do you mean that questions will disappear or are you letting me know that clicking on refresh does what it says?

ManishEarth

@angelatlarge clicking it will flood your main page, but refreshing will make it all back to normal

angelatlarge

21:40

@ManishEarth Oh, you mean the fact that the migrated questions have not actually have had recent activity. Right.

ManishEarth

@angelatlarge yep

angelatlarge

@ManishEarth I was mainly commenting on the fact that I don't think I've seen that notice have more than, say, 20 questions for me.

Let's see if they blow up the RSS feed...

ManishEarth

@angelatlarge Leave a tab open and don't shut down your computer. You'd be surprised :)

angelatlarge

@ManishEarth Except that I look at EE.SE often enough that surprises like that don't happen.

ManishEarth

yep

@ManishEarth baller.

@ManishEarth So awesome!
