Greetings List Lurkers,
The esteemed Ms. Cathy Resmer of no less than Seven Days has indicated
that she will include the BOSI Adult Swim at Hedding UMC in the weekly
Tech Jam News email. Apparently if we fill out http://7dvt.com/postevent
the Tech Jam News, then the Adult Swim can be included in the weekly
schedule. This type of periodic updating may be the reason why people
invented programming. Anybody have any idea how to actuall do this? After
convening the Bosi adult swim here in Barre for the last 350 or so weeks,
I am very afraid that we are about to become famous...
So, this is the official notice of the Barre Open Systems Institute (BOSI)
Adult Swim. The swim stars at 5:00 PM EST, our latest pomp being to
include a goggle hangout https://www.google.com/calendar/render?pli=1
until 7:00 PM EST.
The google-cast aspect is coming right along. Presuming that we have
network connectivity, we may actually repeat the whole special guest thing
that worked so well with Kevin Cole dialing in from DC and Big Mark Kline
tG+ing in from Minnesota.
The next step for the EnGenius directional 801.11 G distance WAN is to
test it betwen the Barre Old Labor Hall and the Barre Central Library. The
goal here is to allow the library another source of income, soi that we
can help defray the cost of the LinuxWorld subscription. These radio link
things are very cool. The radio links for 802.11 can go about 2 miles, we
are looking for other test sites as well. Want 300 Mb/s?
The coolest thing of the month of March, the RaspBMC or OpenELEC on a
Raspberry Pi is still very cool in April. Chris may demo this as well as
other comosite and HDMI This morning I made yet another the bootable Linux
Mint 14 usb stick, with the gnome interface as thi is still very coolest
distribution
The opto isolators as well as the right controller are now here for the
snobot. We can consider testing what Bit Ed helped us figure out about
how to cascade Arduino motor control shield H-bridges to the Big Ass FETS
(BAFs) that run the two control motors. Elves are frantically documenting
the interface, and a stationary test platform is in the works. Yarger has
been buzy liberating the magic white smoke from various of the snowbot
components. This coming week is when we can take a shot at this.
At the risk of repetition, the theory here is you can graduate from a toy
car to a robot and not change a thing in software. So where the opto
isolators come in, is we hook them to a motor shield in order to cascade
the Arduino motor shield H-bridges to the BAFs (Big Ass Fets) on the
snobot (ne powered wheelchair) controller. This will no doubt be placed
in one of the new wire-mould boxes that allow for a roomy enclose of the
Arduino and a few shields. These big boxes allow for a very nice fit, and
pix shall be posted on G+ and the web site. The old skinny wire-mould
boxes are to end up in the furmon project. We are currently trying to
order the double wide Wiremould boxes for PI's. The big size ones are the
most promising. We faded a week due to Uncle Sam and the IRS but continue
to watch this space for action next week.
Right now the Raspberry Pi enclosure the idea for is to use an old 5.25" floppy
box, this works great, again, I expect to get this up as pictures. Do not
forget, if you try this mount the pi pretty far from the edges as you will need
as much as one inch connector clearance. The Wiremould "Trailer Park" project
may change my mind about this as an ideal enclosure.
We hope to expand use of "Andro-Mouse", which is a series of apps for an
Android controller and a Java controlled. This is very slick and Chris has set
up a web page which we will examine and publish at todays meeting, with any
luck.
The "tsp" site has been updated: http://docbox.flint.com:8081/tsp there are now
live shots and consolidated shots of the working beasts (look at the first
three links off this site). One goal is to get the pictures better organized,
and we expect to have pictures of the spiffy new enclosure. You will find on
the site the actual programs that exploit the python miniterm class to gather
data from the Arduino based temperature sensors via the USB. The software
interface between the Arduino and mrtg is solid and have what we need in that
department. This baby is done for the first phase, now for the rewrite...
With mrtg you can trend the sample data, and this is an example that shows you
how to configure MRTG to display this date. There is also a thing called
pylab that makes timeseries data plotting and analysis a snap.
The radio link work from the pellet furnace is now on the pbug development
system. This is a milestone since we now have live data to play with. For more
information see the furmon site as detailed below. The software should
launch, OK - or maybe later. Testing on the 802.11 transmitter that can
replace the point-to-point system, is completed, we are just waiting the
the right customer...
The ever growing list of projects includes:
- http://docbox.flint.com:8081/furmon - monitor that pellet furnace.
- http://docbox.flint.com:8081/arduino - moving in the arduino groove
- http://docbox.flint.com:8081/javajive - to get better at Javascript
- http://docbox.flint.com:8081/tsp - Temperature Sensors Project
- http://docbox.flint.com:8081/robotsrules - The quest for Roberts Rules - - -
- http://docbox.flint.com:8081/visual.bash - Yea, I am not kidding...
- http://docbox.flint.com:8081/mrtg - remedial raw mrtg for the slow...
Otherwise, Barre indeed remains a great venue for a Linux and Open Source
Software meeting and general system rejuvenation. That said, we expect to
assemble more of the Dallas Semi "1-wire" temperature probes, and we have two
Arduinos, with lots of fixin's as well as several Raspberry Pi's and a boat
load of radio modules.
Needless to say the Arduino remains the coolest thing for 2012, the Raspberry
Pi the coolest thing this year, and Ras-BMC the coolest thing for the month of
March...
Do not forget that the Barre library stocks "Linux World", and the latest issue
is here. The DVD's are available to checkout and copy, as I just made isos of
each and every one.
Anyway, come and do open source stuff. For more information about the BOSI
Adult Swim meeting time and location try this:

Show up at the the Hedding United Methodist Church Basement if you have
questions or are interested in Linux or the concept of free and open systems,
The basement of the Hedding UMC facility is actually working out pretty well.
If you wish to be included on the "Linux_adult_swim" mailing list, send a
response to this note. Note that the mailing list system is a bit peevish
right now. Let me know if you have any difficulties. Note that I will be
updating the list-server by next week.
Kindest Regards,
Paul Flint
