The LVL1 Hackerspace will be hosting a Surface Mount Soldering

Workshop on Saturday, November 20th, 2010 from 1 to 5pm.  This
workshop will teach you the basics of soldering surface mount
components with a standard soldering iron, using a standard soldering
iron tip.   You’ll be given the tools required to build your own
surface mount projects, and during the workshop, you’ll work on
assembling your own Open Balloon CPU (A design of LVL1’s own White
Star Balloon Team).  You’ll solder 0805 Resistors and Capacitors, 1206
LEDs, and TQFP Microcontrollers, among others.  You’ll learn about the
packages  which can be hand soldered, and the packages which cannot,
along with the techniques required to assemble a working board.

At the end of the workshop, you’ll walk out with the knowledge and
skills required to build any reasonable surface mount project, along
with your own Open Balloon CPU.  These tools include small-gauge
solder, flux, non-magnetic tweezers, and a magnifying loupe.  The Open
Balloon CPU you’ll be assembling is a VERY general purpose sensor
platform, which can be used for a variety of projects which aren’t
related to Balloons or UAVs whatsoever.  Aside from the form factor of
the PCB, everything about the electronics design is generalized for
whatever development the user sees fit.  We will be outfitting the
Balloon CPU with a temperature sensor and Microcontroller, along with
all the passive components required to burn code onto the chip.  If
desired, workshop attendees may add additional sensors (a Real Time
Clock and/or a Barometer) for additional cost.

If you can read newsprint, and have a reasonably steady hand, you can
solder surface mount components!  We will also be doing demonstrations
of hot-air soldering and hotplate reflow soldering, to provide a small
taste of even more advanced soldering techniques.  We can provide
soldering irons, but if you would prefer to bring your own, feel free.
We also recommend you bring a laptop.  If you’ve got an FTDI cable
and AVR programmer, you can start hacking at your balloon CPU
immediately!

Note:  If we do not fill at least 12 seats by November 10th, 2010, the
workshop will be cancelled, and all tickets will be refunded.  Sign up
early, and sign up often!  Any questions, feel free to send them to

IEEE Soldering Workshop

//

LVL1 and the IEEE Louisville Student Section are happy to announce that LVL1 will be hosting the University of Louisville IEEE and their soldering workshop.

This soldering workshop will take place at 1PM on October, 16th, at LVL1 (814 E. Broadway).  This workshop will bring in 15 Electrical Engineering students from the University, with 5 walk-in seats held for the LVL1 community.  These seats are first-come, first-serve, and the cost will be $10.

Students in this workshop will be soldering together a small variable frequency sound generator based on a 555 timer IC.  Students will learn basic thru-hole soldering skills, wiring components to perfboard.

The IEEE Louisville Student Section is a University Student Organization which serves as a professional and social network for Electrical Engineering students at the University of Louisville.

Fabbing PCBs in China for Fun and Profit

//

For the White Star Balloon project, one immediate need was for an extensible Main Flight Computer platform.  In order to facilitate development, a completely modular design was needed.

In three weeks, we went from this

To This

 
 
 
 
 
 
 
 
 
In brief, this board uses the I2C bus to communicate with multiple slave modules and sensors in order to accomplish the task of managing our balloon’s flight.  More information can be found at our wiki.

To fabricate these PCBs, we chose Gold Phoenix, located in Hubei, China.  They offer some really incredible deals on PCB manufacturing, including $100 for a 2-layer board, 155 Square Inches, 5 day turnaround + 3 days shipping.  We chose this fabrication house since Sparkfun uses them for their own products, as well as BatchPCB services.

Much more below the break.
