Tomorrow - Open Night!

[Sam Harmon]

Open hours tomorrow from 7pm-whenever.

Bring a project if you have one. If not, I'm sure we can find something for folks to work on...

Speaking of projects...
I made some more edits to the 3D Printer spreadsheet, including a list of all the needed printed parts for the Aluminum Mendel, and my opinions as to which parts might be made on the mill (either out of aluminum or HDPE or something):

See you then,

I have a couple SMT chips with pads so tiny I cant even see them without a magnifying glass. They were sent to me by our new TI embedded overlords as sample chips for this technology:

If anyone knows an inexpensive way to make a DIY SMT circuit board and solder the chips to it, we can than experiment with a radio technology that few have yet.

Hey Joe ,all,

Latest greatest for the kind of reflow is to use an electric skillet.

If someone has 1 to bring in i'll bring in the solder paste.

Do you have the part numbers on hand? We can design a breakout board in EAGLE and have OSH Park (http://oshpark.com/) make 3 boards for $5 per square inch. If they're that tiny I doubt we can etch or mill a board in-house with that kind of accuracy right now.

Thanks Sam and Bob,
It's a cc1180 in a RoHS compliant 6x6 mm QFN 36 package.

http://www.ti.com/product/cc1180

This chip costs $3.50 in lots of 100 and so could be teamed with an msp430 for a ~$7 wireless mcu device.

A couple other breakout boards that would be fantastic to have, is for these uniquely inexpensive motion tracking chips:
LPY450AL $6 gyro in a LG-28 package:

MMA8453Q $2 accelerometer in a 16 pin QFN package:

You might also be interested in some products by invensense. They have an all in one 6 axis IMU (3 axis MEMS gyro + 3 axis accelerometer) as well as a 9 axis unit which has a built in compass.

I will be there with one or maybe two other friends. We are new to the ideas of Arduino and related subjects. We're hoping to learn from others and get some info on how and where we can get started. I hope this is ok!

[Joe O'Donnell]

That's beyond OK and into fantastic. There is no better place to get started with the future of fun and tech than the Makers Alliance. We recently moved to a larger adjacent area, and received additional tables, workbenches, chairs and shelving as well. Some unpacking may still be going on tomorrow, but new people are always welcome. I'll be working with the msp430 launchpad board + Android tomorrow, and can guide you in working with one of our msp430 kits. The msp430 is similar to Arduino but cheaper and better. (that should liven up this list) JoeO --- On Mon, 10/15/12, Aaron Lewis <aaronle...@gmail.com> wrote:

On a slightly different note, has anyone started working the GPIO / I2C programming capabilities of the new Java for ARM JDK on the Raspberry PI yet?

R-PI GPIO was covered briefly at JavaOne last week, but the write up notes don't describe the details: https://blogs.oracle.com/javaone/entry/session_report_java_on_the  Apparently someone also connected an EEG to R-PI and used it to control a motor: http://via.me/-5kdsgw4 https://twitter.com/speakjava  There is also a GPIO library for a previous JDK: http://elinux.org/RPi_Low-level_peripherals --- On Mon, 10/15/12, Sean Stallbaum <seans...@gmail.com> wrote:

Thanks Joe :)

I was actually at JavaOne and saw the presentation, it was pretty cool but really high level.

I will definitely take a look at the links, i was more curious to see if anyone in Cleveland had a R-PI ...

Hello. Just wanted to say thank you to everyone for your kindness and hospitality this evening. I'm very sorry I couldn't stay. I honestly would've loved to help organize, it's kinda my thing(and I mean that). I think my enthusiasm for the potential of the group gave my friends a much more exciting picture than was reasonable to them. I, however, still feel that way. I just felt bad for bailing, but would've felt worse for making my friends stay. 

Just to give a lil more detail about myself strictly on related subjects: I went to school for computer networking and received a Cisco certification. I'm very handy with computers of all types especially the hardware aspect. However I am quick at understanding software languages of various types. I'm familiar and use and manipulate Microsoft, Apple, and GNU/Linux based software. I've also been reading/watching vids a lot online on the Arduino language and concepts. But I still know next to nothing about it. Here's my company's website. www.MobileTechIT.com

As far as what I'd like to do: I have a ton of ideas! Most I'm sure have been done. I'd love to build a 3D printer on the quality level of a MakerBot 2 or better. I think it'd be great to make plastic casings and components for the other electronic project ideas I have like the quadcopter. However on a more interesting and larger concept I'd like to make a smart home and control all electrical components from my phone including security and surveillance when not there. 

I recognize that I'm a ways off from such things. But, I never stop pushing myself to learn though. Maybe sometime, I'll let you know about all my previous life endeavors, as examples of that. 

Take care and hope to see you again soon. 

-Aaron
