ASK AN ENGINEER 7/16/2011 (video)

ASK AN ENGINEER 7/16/2011 (video). Text log from the chat/IRC after the jump.

7:02 bigbodynobrain: i kinda don’t want to put it in chat
7:03 Miaximus: Yesh
7:03 Chankster: bigbodynobrain send it in a PM
7:03 richms: email me on richms @ gmail if you want an invite then
7:03 jersagfast: jeremysaglimbeni@gmail.com – someone send my an invite. :)
7:03 Miaximus: Real feedback is golden!
7:03 Nashblackcat: I wish we had a hackerspace in Nashville…
7:03 wa7iut: hello
7:03 RoboMaster: It’s like instant hackaday.
7:03 yachris: I’ll invite jersagfast
7:04 RoboMaster: Yes, please stream it\
7:04 jersagfast: Thanks yachris!
7:04 Nashblackcat: :D
7:04 hammerhead74k: Why not just do it the same way you do youtube & webpages?
7:04 georgegraves: Very cool. We recorded so you guys will get to see it.
7:04 yachris: np :-)
7:04 BeauvoirR: but hopefully without the trolls
7:04 Nashblackcat: Make sure you tell google you would like that as a G+ feature
7:04 socket11: Hello All!
7:04 socket11: 廁所在哪裡?
7:04 Zadster: Dontcha love technology
7:05 jersagfast: Anyone else have massive pauses in the video?
7:05 georgegraves: trolls.
7:05 ChrisGammell: kicking people out would be bad in both directions
7:05 Miaximus: Thats awesome george!
7:05 aeiche: Hello
7:05 johngineer: there ought to be moderated hangouts… i mean, i’d think that would be a feature.
7:05 granitepenguin: there should be the concept of a moderator , though
7:05 granitepenguin: Rickroll
7:05 Dosbomber: As soon as it becomes more popular, they’ll need a kickuser function
7:06 rdump: i cured my massive rebuffering pauses in the video by killing off google automatic update. it picked the worst time to force a new version down my throat
7:06 wa7iut: great idea
7:06 ChrisGammell: guess so, nice thing is the chats will keep up after the mod leaves
7:06 Nashblackcat: Gotta love a Beta
7:06 jersagfast: Arduino powered troll boot
7:06 Miaximus: Yes
7:06 AngrySpinach: Buy my arduino clone!
7:06 Miaximus: Agree
7:06 georgegraves: yep
7:06 richms: I will do it once it is a little warmer in my workspace
7:06 AngrySpinach: Obey my dog!!!
7:06 aeiche: My project wasn’t ready to show off, so hopefully next week!
7:06 socket11: Cats rule!
7:06 hammerhead74k: Buy my new SOLDERAGRA! Guaranteed to make your iron HAWT! ;)
7:07 AngrySpinach: Q: Is Radioshack in Canada?
7:07 aeiche: I just saw the DIY QR code at a shack yesterday
7:07 Dosbomber: ew hammerhead
7:07 georgegraves: Speaking of spam, RS has been hammering me with emails. I wonder where they got my address?
7:07 socket11: They push this in store also!
7:07 ChrisGammell: haha, Radio Shack probably had some MBA that said “I HAVE THIS AWESOME IDEA”
7:07 ADAbot: :: Welcome to the weekly adafruit “ask an engineer chat” ::
7:07 ADAbot: :: for all the makers here – use the code “NYAN” to get 10% off many kits!
7:07 ADAbot: :: at the end of the hour we will have a special giveaway!
7:07 ChrisGammell: “DID YOU GUYS KNOW PEOPLE MAKE STUFF ONLINE?”
7:07 johngineer: and he got a promotion too, Chris.
7:07 granitepenguin: buy parts from them
7:07 Zadster: Best way to track that George is to get your own domain and signup with sitename@mydomain.com
7:07 thoughtfix: Heathkit computers!
7:07 ChrisGammell: yes, yes he did John
7:07 RoboMaster: I hope that RadioShack pushes this more in stores.
7:08 Chankster: sadly though their parts are over priced
7:08 hammerhead74k: I had a 200-in-one kit… was cool. :)
7:08 thoughtfix: My first computer was a Heathkit 286 at 10 MHz
7:08 georgegraves: yea zadster. There is also a way to go it in gmail by adding asuffix to your email addy
7:08 johngineer: Every time an MBA gets promoted, an engineer cries.
7:08 socket11: I know a mgr. in a store and they are working it.
7:08 Improviser: I built the old Science Fair kits from RS
7:08 excavatoree: I still have my H-89. (Z80, running 8080 code)
7:08 Nashblackcat: I use to work for them
7:08 jersagfast: When i worked for radio shack, any invention that i made was theirs, even a year after leaving
7:08 AngrySpinach: Mine was a Dell latitude at 2GHz
7:08 ChrisGammell: nothing lik an old codger coming in and yelling at you that all the 2n2222s are gone
7:08 physics_dude: Reminds me about the scene in “Short Circuit 2″ where that dude had to repair the Jonny 5.
7:08 Miaximus: Yes, the combination of the build-it kits + the awesome tutorials + the community is a huge draw (at least for mep
7:08 Len17: @AngrySpinach RS in Canada was sold and is now The Source
7:08 Improviser: Worked for them17 years
7:09 mikeortman: .
7:09 socket11: CORP!
7:09 Nashblackcat: I made so much money off of helping people fix things rather than sell new stuff to them
7:09 mightymik: I go back to P-boxes
7:09 jersagfast: Velleman masters : Radio Shack
7:09 georgegraves: One’s bigger
7:09 mikegrb: I worked at RS in high school and loved when customers came in for parts for something and I could help them solve their problem drawing a schematic on reciept paper
7:09 Improviser: when it was Tandy corp and they actually manufactured things
7:09 jersagfast: Ditto!
7:09 ChrisGammell: @mikegrb, that’s awesome
7:09 Nashblackcat: I left when the wall of parts was gone :(
7:09 socket11: Let people play!
7:09 ChrisGammell: how about one of those vending machines that Best Buy has
7:09 ChrisGammell: like in the airports
7:10 hammerhead74k: What kind of reception can I get with this Arduino? How much is the data plan for it? ;)
7:10 AngrySpinach: I would go to San Fransisco if that was created
7:10 thoughtfix: Hahaha I’d commute to SF for that.
7:10 ChrisGammell: or whoever sells iPods
7:10 reipoom: i don’t think i’ve been to a radioshack with intelligent staff
7:10 AngrySpinach: I live in london
7:10 thoughtfix: But there are several hackerspaces in the SF Bay.
7:10 jersagfast: Do you want a cell phones!!
7:10 RoboMaster: They need to utilize the fact that it’s very convienient to buy at RS instead of ordering online, for like the weekend project
7:10 Nashblackcat: Some rat shacks are still indy
7:10 mikegrb: yeah laser cutter, and 3d printer
7:10 jmcglinn: and Seattle
7:10 socket11: Hackerspace in an airport? good idea!
7:10 Nashblackcat: I could see that
7:10 AngrySpinach: Buy the Viagra
7:10 Nashblackcat: :D
7:10 mikegrb: time is free if you buy the parts at that location
7:10 thoughtfix: Viagra’s expensive dude.
7:10 socket11: Love NPR !!! funny!
7:10 Nashblackcat: Sometimes NPR has no clue
7:11 drenboy: ohh i tot he meant neil patrick harris
7:11 Miaximus: lol
7:11 johngineer: NPR is my favorite comedy radio station.
7:11 Dosbomber: I went to a Radio Shack once and got hit on by one of the female clerks… still can’t figure that one out.
7:11 Nashblackcat: lol good one John
7:11 socket11: LOL
7:11 thoughtfix: That’s like saying “Sony contributes to iPod’s success.” Yeah kinda — because they make crappy products by comparison!
7:11 seanpalmer: I’m upset :)
7:11 jmcglinn: speaking of viagra… http://xkcd.com/924/
7:11 usunoro: having worked at radioshack for a few years, most female employes are broken on a fundemental level
7:11 Improviser: Radio Shack ripps everyone off
7:11 reipoom: yeah
7:12 johngineer: let’s move on from Radio Shack, shall we?
7:12 georgegraves: Alright. enough about Radio shack. We’re moving on. —————–
7:12 reipoom: most of the staff seem like highschool dropouts
7:12 socket11: I like local componet shops!
7:12 reipoom: at least in peoria IL
7:12 Miaximus: Nice
7:12 Improviser: now lets kill Microsoft!!!
7:12 jersagfast: Can i have your email for a coupoun?
7:12 thoughtfix: hahaha
7:12 Improviser: or Micro$oft
7:12 drenboy: community pressure! woot!
7:12 Miaximus: At least future stories about it will be more true.
7:13 Nashblackcat: Did they air a correction ?
7:13 AngrySpinach: The SDK kinda sucks
7:13 guysmiley48x: MS wants a taste of any commercial kinect applications
7:13 socket11: I want a piece of this!
7:13 AngrySpinach: sorta like apple
7:13 AngrySpinach: 99.9% please
7:13 Improviser: Microsoft missed the boat and will never admit to it
7:13 yachris: I refuse to believe M$ is losing money on the Kinect. They never did on the XBoxes…
7:13 RoboMaster: ?: did NPR state a correction?
7:13 richms: MS have to care about how they licensed the technology, randoms buying it and hacking it dont have to give a damn about the license that MS paidfor etc
7:14 thoughtfix: It’s not losing money. It’s called a “loss leader” … big difference
7:14 thoughtfix: EMSL!
7:14 Miaximus: Looks cool :)
7:14 AngrySpinach: nyan
7:14 seanpalmer: That is the best adaptation of Nyan cat ever
7:14 ADAbot: :: Welcome to the weekly adafruit “ask an engineer chat” ::
7:14 ADAbot: :: for all the makers here – use the code “NYAN” to get 10% off many kits!
7:14 ADAbot: :: at the end of the hour we will have a special giveaway!
7:14 Nashblackcat: POV
7:14 BeauvoirR: long exposure light painting
7:14 jmcglinn: what is NYAN?
7:14 Miaximus: Ahhhhh
7:14 BeauvoirR: POV is a brain process
7:14 seanpalmer: I liked the original project, but this is amazing
7:14 joachimbean: go to a lighting studio :P
7:14 AngrySpinach: not POV
7:14 BeauvoirR: if you can’t see the effect IRL it’s not POV
7:14 jersagfast: Persistance of Vision
7:14 johngineer: PO
7:15 socket11: Cool!
7:15 yachris: Persistence of Long Exposures, then :-)
7:15 georgegraves: If could be POV if you run really fast.
7:15 Improviser: could be used for pov on the side of a semi truck
7:15 Miaximus: Its very nicely done
7:15 AngrySpinach: presistance of camera vision
7:15 ChrisGammell: get out your ol’ 35mm
7:15 johngineer: persistance of machine vision
7:15 socket11: What moved?
7:15 BeauvoirR: hmm, not sure I agree with that
7:15 ChrisGammell: develop the film
7:15 seanpalmer: original http://www.nearfield.org/2011/02/wifi-light-painting
7:16 ChrisGammell: spend hours in the dark room
7:16 Chankster: socket11 the earth
7:16 johngineer: film. seriously.
7:16 yachris: Film? What’s that?
7:16 mndless: but the grass and the building show no evidence of movement
7:16 ChrisGammell: ya know
7:16 jersagfast: The LED stick
7:16 ChrisGammell: the filmy stuff
7:16 guysmiley48x: the camera is locked down
7:16 georgegraves: camera on tripod
7:16 Chankster: the stick floated in thin air
7:16 Improviser: long exposure
7:16 Chankster: the earth moved
7:16 jersagfast: Shutter on bulb with remote
7:16 enzyox: Note the bouncing
7:16 ChrisGammell: my friend does glass frame exposure photography
7:16 ChrisGammell: it’s crazy
7:16 socket11: Looks 3d as the background stays
7:16 johngineer: i’ve done that.
7:16 johngineer: it’s fun.
7:16 Improviser: just ike car light streaks
7:16 Miaximus: I love these, gonna make a pool light out of them in a month or two
7:16 guysmiley48x: using the LED strip is genius
7:16 ChrisGammell: much in the same way people say “Why do you guys MAKE this stuff”
7:17 enzyox: It must be hard to walk with the stick
7:17 ChrisGammell: its the process
7:17 johngineer: or, i used to, before my darkroom got flooded.
7:17 johngineer: :(
7:17 ChrisGammell: ouch
7:17 ChrisGammell: how?
7:17 ChrisGammell: with developer?
7:17 johngineer: no. basement flooded.
7:17 ChrisGammell: ah
7:17 mikegrb: what developped of the flood?
mikegrb runs
7:17 ChrisGammell: just plain ol’ water, eh
7:17 johngineer: then we had to get rid of the mold.
7:17 ChrisGammell: yuck
7:17 ChrisGammell: sucks man, sorry
7:17 thoughtfix: XKCD :D
7:17 AngrySpinach: lol xkcd
:35 richms: Q: do you have the longer ones like you supply with the ftdi friend available?
7:35 AngrySpinach: Solder a header pin to an alligator clip
7:35 Nashblackcat: It is so easy to make quick and dirty jumpers with some heat shrink
7:35 Nashblackcat: :)
7:35 socket11: Standard board headers.
7:35 RoboMaster: Yep, can see the bumps, that’s good
7:35 ADAbot: richms: Q: do you have the longer ones like you supply with the ftdi friend available?
7:35 hammerhead74k: Flush cutters work well with that as well.
7:35 LapsusAntepedis-1: Q: is it possible to get header strips that are equally long on both sides for connecting female sockets to breadboards, for example?
7:35 fennec: count twice before breaking
7:35 socket11: Love them!
7:36 AngrySpinach: you broke my arm!!!
7:36 scott-42: Q: is there a male breakable version?
7:36 AngrySpinach: ow
7:36 scott-42: Q: I mean female
7:36 yachris: Q: Are you going to stock female ones?
7:36 Nashblackcat: I would use some flush cutter if you want to make jumpers sometime it can split with diags
7:36 kieno: you can move the plastic to make them the same length
7:36 hammerhead74k: It is possible… I have seen them.
7:36 scott-42: Thanks
7:36 georgegraves: Cut them with a small hack saw.
7:36 richms: cut thru one of them to destroy it and then file it smooth
7:36 Dosbomber: Dremel the edges and they’re technically “breakable”
7:36 socket11: Table saw? LOL
7:37 yachris: chainsaw :-)
7:37 AngrySpinach: laser
7:37 socket11: LOL
7:37 jersagfast: Torch.
7:37 Miaximus: Oh yeah
7:37 jmcglinn: the kerf on a chainsaw and table saw is going to eat more than 1 pin
7:37 AngrySpinach: godzilla
7:37 Miaximus: I like the thinner body
7:37 hammerhead74k: Laser cutter? Waterjet? LHC? ;)
7:37 AngrySpinach: Will buy
7:37 joachimbean: Can you make an iWristband?
7:37 rougenaxela: jigsaw on header would be a disaster
7:37 yachris: LHC WINS!
7:37 Miaximus: hehehe
7:37 jersagfast: Dremel
7:37 Dosbomber: 5mm smaller… wow
7:37 socket11: CNC!
7:38 richms: would be awesome to have the logo on both sides and 2 LEDs inside
7:38 Nashblackcat: Such a smart idea, gonna sell them like hot cakes. :)
7:38 Len17: It’d be cool if you could actually turn the person off by pressing it.
7:38 jersagfast: Oohhhhh!!!
7:38 ChrisGammell: Q: Have you guys caught any flac from them Apple yet over creating something similar to their product?
7:38 AngrySpinach: Q: Haven’t apple trademarked the letter i yet?
7:38 georgegraves: I got a mini hacksaw on ebay for $10 shipped or something. Works perfect. You kinda need a small vice though.
7:38 Improviser-1: a hammer works good
7:38 Zadster: its a generic logo, not apple’s
7:38 thoughtfix: Want to buy: pin
7:38 Len17: It’s not an Apple thing it’s an ISO standard.
7:38 seanpalmer: chris: you mean ALAC :)
7:38 fennec: it might be fun to make the case itself part of a capacitive sensor so the cufflinks could process a touch
7:38 jersagfast: ISO
7:38 Nashblackcat: PanaVise
7:38 socket11: Best tool HAMMER!
7:38 johngineer: everyone i’ve shown the cufflinks too is super jealous.
7:38 yachris: At my age, all my vices ar small :-)
7:38 yachris: :-)
7:38 georgegraves: lol
7:38 ChrisGammell: oh crap
7:38 ChrisGammell: I asked
7:38 hammerhead74k: Q: How many sales have you made on the cufflinks?
7:38 Miaximus: lol
7:39 thoughtfix: ooooooo!
7:39 AngrySpinach: two!!!!
7:39 physics_dude: O_O
7:39 zool: lol huge
7:39 fennec: oooh charliplexing eh?

mikegrb unzips
7:39 Dosbomber: omfg… I just did an 8×8 RGB LED matrix and it took me 3 days to build it from scratch. :P
7:39 jersagfast: My video isbehind, what isit??
7:39 scott-42: WANT
7:39 ADAbot: these are usually on the sides of busses that have video
7:39 ChrisGammell: thousands and thousands adabot? That’s a lotta dough!
7:39 hammerhead74k: @Adabot – sweet! :)
7:39 RoboMaster: RGB! you’re spoiling us!
7:39 Miaximus: Note the text Adapeoples! This will sell
7:39 georgegraves: driven by???? – oh I can’t ask!
7:39 Chankster: SHINY LEDS! I WANT!
7:39 bigbodynobrain: Q: thru-hole or SMD
7:39 mikegrb: OMG OMG OMG when can haz
7:39 ipadfanboysf: You better make a LOT of these… :)
7:39 seanpalmer: 16x24x?? bits per color?
7:39 richms: so long as it is affordable, yes
7:39 ADAbot: chris, it’s a good seller already – we’re really happy with it
7:39 AngrySpinach: hehehehehehe pretty colours, all mine
7:39 Nashblackcat: DONT ASK !
7:40 Miaximus: Nice
7:40 ADAbot: we’ll likely sell more necklaces though
7:40 Miaximus: :D
7:40 ChrisGammell: woot, hire more people! :-)
7:40 Improviser-1: on board drivers
7:40 ChrisGammell: economic growth FTW!
7:40 fennec: i bet these are gonna be $$$
7:40 Chankster: ^^
7:40 ChrisGammell: but WHERE WILL YOU GUYS POST THE JOBS?
7:40 ChrisGammell: haha
7:40 ChrisGammell: sorry
7:40 yachris: fennec: Absolutely
7:40 Zadster: I can imagine people wearing pendant ones on their shoelaces
7:40 ChrisGammell: I”m pandering to myself
7:40 ADAbot: so far we haven’t needed to use our own jobs boards yet!
7:40 Miaximus: Interesting
7:40 Nashblackcat: http://www.adafruit.com/jobs/ ?
7:40 ChrisGammell: do eeeeet
7:40 Nashblackcat: XD
7:41 jersagfast: WANT!
7:41 Improviser-1: so shift register driven
7:41 thoughtfix: Q: Is this a kit or a fully soldered panel?
7:41 ADAbot: so far we’ve been hiring people we know, but eventually we’ll use our own jobs boards too
7:41 georgegraves: I’m guessing those are surface mount LED’s.
7:41 fennec: somebody get workin’ on an arduino mega library stat
7:41 Miaximus: I think I would want to get really good at the LED strips before I jump into something this more complex (for me)
7:41 ADAbot: it’s not out yet, can’t ask :)
7:41 ChrisGammell: yeah, that’s good to hire those you trust
7:41 thoughtfix: Damn
7:41 ADAbot: but we’ll have it soon
7:41 hammerhead74k: Build your own jumbotron!
7:41 ChrisGammell: harder to hire new folks, messes with the culture
7:41 fennec: any chance to power it on vid?
7:41 ChrisGammell: and you guys seem to maintain that well
7:41 socket11: So a split drive function?
7:41 Chankster: MAKE IT BLINKY!
7:42 AngrySpinach: over already
7:42 Improviser-1: kinda like driving a shift brite led
7:42 ChrisGammell: we need a script so that every time there’s a question mark, the bot shouts at that person
7:42 jersagfast: Just a few MCD?
7:42 AngrySpinach: :-(
7:42 mikegrb: that panel is “Sex on a stick”
7:42 socket11: Nice!
7:42 thoughtfix: Q: Will you please please please release Mega shields?
7:42 AngrySpinach: ewwww
7:42 seanpalmer: Q: How’s your hair?
7:42 physics_dude: q: What would be the use for a 1 gigohm resistor?
7:42 AngrySpinach: What is bes
7:42 marty200: a
7:42 robertmeffe: I am trying to “hack” a circuit board to control the binary rotary encoder via a microprocessor. What is the best way to replace the binary rotary encoder with something I can control via a microproce
7:42 AngrySpinach: oope
7:42 AngrySpinach: oops
7:42 ChrisGammell: physics_dude should know physics
7:42 StandardRockets: With all auto electronics, why do they generally advise you disconnect the negative battery terminal and not the positive?
7:42 thoughtfix: I know – but I want to stack say … Xbee and Motor
7:42 richms: the SPI is a PITA with a mega
7:42 ChrisGammell: :-)
7:42 electropants: Hi! I’d like to install about 2 m of the RGB LED strips into pants. Could you suggest how to power them?
7:42 ADAbot: sean: engineer/electronics questions, thanks!
7:42 AngrySpinach: typing in darak=hard
7:43 LapsusAntepedis-1: Q: as a next step past the arduino, what do you think of the leaflabs maple?
7:43 electropants: The 3.7 LiPo battery on sparkfun + the 5 V converter is only rated up to 600 mA, but my design could draw up to ~4 A…
7:43 AngrySpinach: dark
7:43 Zadster: Bleed resistor on a HV generator?
7:43 electropants: (is 20 watts a bit much?)
7:43 joachimbean: Q: when are you going to get the Arduino ADK and Ethernet?
7:43 StandardRockets: Q:With all auto electronics, why do they generally advise you disconnect the negative battery terminal and not the positive?
7:43 Dosbomber: Yeah, people’s talents should be represented by their online handles…. oh wait.. nevermind. :P
7:43 socket11: NFC for posters or a portal close to a kit?
7:43 richms: StandardRockets its so if your tool hits the chassis, there is no spark
7:43 hammerhead74k: Depends on the rotary encoder – TTL out, or switch type, or…
7:43 RoboMaster: Q: The POV camera nya hack: did he run at an even speed or hook it up to an accelerometer or something?
7:43 AngrySpinach: Q: What is the best arduino/clone to leave in a project?
7:43 ChileanRegulator: q:Why does the internal EEPROM in the arduino have a limited life. What does wear out?
7:43 Nashblackcat: Q: I needed to take the 3,5mm jack of the waveshield to fit it in a case and it wont play from the speaker hardwired to the board, does it have to have the jack to work?
7:43 Zadster: if you accidentally drop it, it will only short to ground, which isnt a problem
7:43 robertmeffe: its binary define by set on/offs
7:44 scott-42: Q: Can you recommend a good beginner book for PCB design and layout for DIY to get you ready for a board house run?
7:44 ADAbot: StandardRockets: With all auto electronics, why do they generally advise you disconnect the negative battery terminal and not the positive?
7:44 granitepenguin: Q: Are you considering a WiFi shield product?
7:44 excavatoree: Convention. Doesn’t matter
7:44 ericwertz: safety
7:44 jersagfast: 1,000,000 cycles for EEPROM in arduino as tested bt tronixstuff.
7:44 hammerhead74k: So you can’t short to ground?
7:44 _oPossum_: Becuase you may short the tool to the chasis!
7:44 Zadster: correct hammer
7:44 socket11: The chassie is ground all over!
7:44 guysmiley48x: hot is keyed whereas ground is direct to chassis maybe?
7:44 bigbodynobrain: – is ground and it is linked to the entire chasis
7:44 Haremtech: Because usually earth is attached to chassis
7:44 Improviser-1: you are more likely to touch a ground first
7:44 ADAbot: electropants: Hi! I’d like to install about 2 m of the RGB LED strips into pants. Could you suggest how to power them?
7:44 fennec: Q: Do LEDs (without plastic optics) emit polarized light natively?
7:44 ChrisGammell: carefully
7:44 Miaximus: lol
7:45 Miaximus: yes
7:45 Nashblackcat: less likely to get yourself in between the hot side and the battery, ever shorted a car battery ?
7:45 socket11: Lets meet!!!
7:45 Nashblackcat: :D
7:45 seanpalmer: iLuminate
7:45 socket11: lol
7:45 excavatoree: It only matters if you are disconnecting the battery. When you remove the +, you might touch the frame/body with the wrench.
7:45 ericwertz: if you leave the hot line connected the circuit is still hot when it appears to be off
7:45 Haremtech: If you disconnect positive first you have a huge chance of shorting out to earth. Not so if you disconnect earth first
7:45 bigbodynobrain: NYAN-PANTS
7:45 ADAbot: LapsusAntepedis-1: Q: as a next step past the arduino, what do you think of the leaflabs maple?

7:47 Nashblackcat: Q: I needed to take the 3,5mm jack of the waveshield to fit it in a case and it wont play from the speaker hardwired to the board, does it have to have the jack to work?
7:47 richms: boarduino is great when put into a DIP socket on a protobaoard
7:47 Len17: I’ve used Pro Mini, DC Boarduino, USB Boarduino, Diavolino – depdns on the situation
7:47 AngrySpinach: Q: If you could put one sensor (with data logger) into (near) space what would it be?
7:47 ADAbot: Nashblackcat: Q: I needed to take the 3,5mm jack of the waveshield to fit it in a case and it wont play from the speaker hardwired to the board, does it have to have the jack to work?

7:48 jersagfast: Thanks George
7:48 Nashblackcat: Ohh ok
7:48 thoughtfix: And did you pet MOSFET for me? ;)
7:48 Nashblackcat: just never for the email
7:48 georgegraves: “” The EEPROM saw it’s first write error after 47 days and 1,230,163 cycles. This is an order of magnitude better than the spec on the atmel datasheet, but similar to the results of similar experiment
7:48 Nashblackcat: I will tell him to look at it again
7:48 socket11: Burn something up and you will get it!
7:48 ADAbot: granitepenguin: Q: Are you considering a WiFi shield product?

7:49 ADAbot: RoboMaster: Q: the barometric sensor you featured today: I’m curious how one solders to it; the pads are on the bottom so how do you get at them when soldering??
7:49 richms: Whatever you do, allow for an ext antenna on any wifi device so a yagi can be attached ;)
7:49 fennec: Q: Have you dreamt of any circuits other than storage that might benefit from memristors?
7:49 jersagfast: Ladyada has GREAT tutorials on PCB’s
7:49 hammerhead74k: @cadmando – not very well. Most servos are only happy with a continuous signal.
7:49 ADAbot: granitepenguin: Q: Do you have any tutorials or information about designing your own PCBs and getting them made?
7:49 enzyox: I have a mix of 1.1V 3.3V and 5V analog sensors… TXB0108 can hanlde my 3.3V, how about my 1.1V sensor?
