7:07 AngrySpinach: 1 baud
7:07 drenboy: lol
7:07 saytest-1: the limit of hangout is just 10 πŸ™
7:07 Dosbomber: Oh, it’s recorded as it happens, but not pre-recorded.
7:07 wtfwtfdef: i was on smoke signal binary 10,000 years ago
7:07 AngrySpinach: It was called “the postal system”
7:07 Zadster: back in the olde days, everyone had to do Show n Tell over Morse telegraph
7:07 wtfwtfdef: the man who invented the wheel used it as a ornament before finding a function
7:08 drenboy: lol they called it hackerspace teepee ;p
7:08 Tekee: We can deal with the adversity.
7:08 AngrySpinach: the town crier would relay my show n tell message
7:08 mark8675: Don’t cross the Ustream

7:09 ipadfanboysf: Thanks, I always wondered how that’s pronounced.
7:09 AngrySpinach: I hacked my alarm clock to acutally wake me up for this!!!
7:09 wtfwtfdef: the way its spelt, its pronounnced pa-kube-bee
7:09 drenboy: its a flu-virus soundalike
7:09 SierraNevada1: dual video is kind of iffy sometimes though
7:09 ADAbot: george: yah, virtual web cams with ustream and google+ hangout don’t work
grySpinach: Tekee “DA” bomb you mean
7:11 ADAbot: we all need to make a wiki or something for the video stuff
7:11 AngrySpinach: yes
7:11 addidis: yeah and perhaps design some sort of audio mixer
7:11 jersagfast: good idea.
7:12 AngrySpinach: video vednesday
7:12 AngrySpinach: or wideo wednesday
7:12 Len17: No Zednesday is Zencart.
7:12 ransomhall: tried thingspeak… nice graphing
7:12 Len17: I think they’ve run out of days.

7:12 AngrySpinach: waskawy wabbit
7:12 drenboy: wideonesday ;p
7:12 wtfwtfdef: mail is dead
7:12 wtfwtfdef: eventually you’ll just recdeive a 3d printer file to your local 3d printer
7:12 drenboy: parcels aren’t dead tho
7:12 ashleyvansteenacker: the same in belgium
7:12 AngrySpinach: Streaming Saturday
7:12 socket11: Ugly stamps!
7:13 jersagfast: Blog post:
7:13 jersagfast:
7:13 raysolomon: last time I mailed a letter was 10 years ago
7:13 AngrySpinach: what is mail?
7:13 wtfwtfdef: the postal system is dead like cd’s, and the way books will be
7:13 wtfwtfdef: dead as doornails
7:13 mjusticz: That’s an exaggeration
7:13 AngrySpinach: Sort of like 3d tvs in 5 years
7:13 mjusticz: How else would you get things you bought online?
7:13 socket11: Boo! LOL
7:13 wtfwtfdef: there will always be a niche market
7:13 Dosbomber: UPS
7:13 wtfwtfdef: like for vinyle
7:13 mjusticz: You need a shipping infrastructure
7:13 mjusticz: and you can’t leave that to private companies
7:14 Zadster: post office closures here in the UK is a big deal too
7:14 ransomhall: gah! dont make me go to walmart
7:14 wtfwtfdef: you can still pick up vynle lp’s and make tube-amps for the instrument qualities
7:14 drenboy: we need a service which provides APIs to the mail services
7:14 socket11: Wal-mart will have everything in 10 years.
7:14 jmcglinn: seven11 in canada
7:14 mjusticz: UPS could then dictate whatever cost they wanted…
7:14 Miaximus-1: I’m sure we’ll loose Saturday USPS soon
7:14 mjusticz: ending usps is creating a monopoly
7:14 yachris: Well, there’s fedex too
7:14 jersagfast: They are going postal!
7:14 mjusticz: or price fixing could occur between fedex and ups
7:15 jmcglinn: i want to see the sorting machines
7:15 ipadfanboysf: I’ve been really impressed with how fast Priority Mail from Adafruit arrives in SF. Same as UPS 3 day air.
7:15 Joebanks: DHL lost too many US customer’s shipments for me to ever use them again
7:15 ransomhall: letters to santa go where?
7:15 danmongeau: if you have the oppourtunity, or call around, team up with a local business who may be pushing enough volume with UPS or FedEx and have good discounts.. makes a BIG difference.
7:15 wtfwtfdef: mail will go the way of the ponyexpress
7:15 drenboy: that picture loos so happy
7:15 drenboy: *looks
7:15 saytest-1: they have specialized imaging tech for OCRing address
7:15 raysolomon: look closer
7:15 wtfwtfdef: once digital printing becomes more real, and the atoms will create the actual molecule, so the same molecular weight and strentght of material is there
7:16 georgegraves: blog post:
7:16 Miaximus-1: No I don’t think it will ever completely go away, the Government needs the ability for us to mail things To them
7:16 addidis: cheers
7:16 Miaximus-1: UPS/Fedex are great for Inboud, but you still need Outbound for taxes, etc.
7:16 drenboy: oh that’s cool
7:16 AngrySpinach: Q: Is the post office in the states private or national???
7:16 bob_mct: interesting
7:16 Dosbomber: Federal
7:16 socket11: National
7:16 zerth: half and half
7:16 AngrySpinach: cool
7:16 jmcglinn: NYC to westcoast is slowish
7:16 Zadster: big hub in Memphis too
7:16 johngineer: yeah it’s privatized but with a federal mandate
7:16 ashleyvansteenacker: qustoms 90 das
7:16 jersagfast: i heart NY
7:16 ransomhall: the other half is funded by junkmail
7:16 zerth: it needs to cover its own funding, but is run by the gov
7:17 mjusticz: or a dead body
7:17 jersagfast: Like the parts soldered..
7:17 socket11: Cool idea!
7:17 Zadster: I’m a saddo, I love tracking parcels from half way around the world
7:17 jersagfast: in the RS pic
7:17 mjusticz: just sayin’
7:17 drenboy: Zadster – me 2 lol
7:17 AngrySpinach: tracking systems are the bane of my life
7:17 saytest-1: anchorage, AK is a big air shipping hub to Asia
7:17 AngrySpinach: I cannot look away

7:32 AngrySpinach: hyper cool
7:32 Dosbomber: What was “stolen” from Bill Gates?
7:33 yachris: 640k πŸ™‚
7:33 Zadster: Its a nightmare getting information about accessing SD cards in fast mode
7:33 jersagfast: lol
7:33 addidis: or if it is triggered externally
7:33 johngineer: higher cost
7:33 ashleyvansteenacker: the image of the sd card
7:33 Improviser: Q : Use it to record servo position data?
7:33 Dosbomber: lol
7:33 paperkettle: Q: This board is perfect for a project I have in mind – random side question – have you ever considered a breakout for AT90USB1286 like the one you have for ATMEGA32U4?
7:33 ransomhall: SDHC realtively cheap
7:33 AngrySpinach: ninjas
7:33 ransomhall: per Mb
7:33 jersagfast: Mac OSX, oh wait, nevermind..
7:33 AngrySpinach: watch out for ninjas

7:41 Fightcube: rubber baby buggy bumpers πŸ˜‰
7:41 yachris: Spammers are relentless. I run a site with a contact form, lots of code to keep spammers out, they still figure it out.
7:42 AngrySpinach: I have no bumpers πŸ™
7:42 albertstraub: AngrySpinach – Exactly! Way too much time.
7:42 Zadster: aka Feet
7:42 johngineer: another thing to remember is that the ADC values fill a 16-bit field with 10-bits of data, so you’re sending 2 bytes instead of one, so cut that number in half again…
7:42 georgegraves: PART FINDER FRIDAY – Rubber bumpers:[]=bumper
7:42 socket11: These rock!
7:42 yachris: All to spam two or three people… sad…
