News and Events

The "official" calendar of the Homebrew Mobile Phone club is hosted by Google at The Homebrew Mobile Phone Club Calendar Page.

The Silicon Valley Homebrew Mobile Phone Club has monthly meetings, usually at the TechShop in Menlo Park. The next meeting is tentatively scheduled to coincide with the Creative Commons Salon in San Francisco on the 8th of November, 2006. For info on previous meetings, check out the Previous Meetings Page.

Other events of interest include the 2007 O'Reilly Emerging Telephony Conference taking place near the San Francisco Airport on the 28th of February and 1st of March.

Projects

Homebrew Club members are encouraged to post information about their projects (or other people projects) here.

One project that's been relatively sucessful is the TuxPhone Project. TuxPhone was started by Surj Patel and Deva Seetharam and quickly attracted Matt Hamrick, Colin Cross and Leonardo Bonanni. The goal of the TuxPhone project is to produce a design that can lead to a "do it yourself" mobile phone; not just for the project members, but for anyone who wants to use the design.

Another project we're tracking is the SqueakyMoPho Project. SqueakyMoPho was Matt Hamrick's original concept for building a Linux-based mobile phone where application and UI code was written in Smalltalk. The project is no on semi-hiatus while Matt works on TuxPhone and Albion.

The Albion Project is a hardware project to build a phone that uses a fully digital audio path. The idea being that the digital audio path will allow you to add features like "Data over GSM Voice" for vCard bursting.

Suppliers

GSM Modules

SparkFun

SparkFun supports several different electronic hobbyist communities. They provide eval boards and accessories for a number of different hardware architectures. We like them because they will sell Telit GSM modules in single quantities and with USB to Serial eval boards.

Embedded Controllers

GumStix, Inc.

GumStix manufactures and sells small ARM based embedded systems for experimenters, hobbyists and companies building small-run systems. Several price-performance points are supported (meaning they have cheaper, slower modules and faster, more expensive modules.) Support for sound, networking, etc. is provided by daughter-boards. GumStix are used by a number of projects and are part of the initial TuxPhone hardware reference design.
Developers should note, however, that typical GumStix systems do not ship with LCDs. GumStix CTO Chris Hughes explains that the company received radically different LCD requirements from their customers, and they could never find a "one size fits all" solution. However, all the control lines for supporting modern LCDs are provided by the system's standard Hirose connector and the LCD page on GumStix.Org lists the steps to connect typical LCDs to the device.

Displays

EarthLCD

When you need to connect an LCD display to your design, the folks at EarthLCD can help out. They stock a wide range of LCDs and controllers.

Keypads

Pannam Imaging

Pannam manufactures custom "membrane" switch type keypads. These keypads may be slightly expensive for some hobbyist designs, but if you need a custom keypad, it's a good alternative.

Nelson Nameplate

Nelson Nameplate is another company that makes custom "membrane" keypads.

Discrete Components

DigiKey.Com

With a catalog the size of a phone-book, DigiKey is well known in the hobbyist and entrepreneureal communities as being a highly reliable source for everything from resistors to project enclosures.

Mouser Electronics

With a catalog the size of a small phone-book, Mouser is also well known amongst hobbyists, hackers and prototypers.

Jameco Electronics

Jameco is yet another supplier of small components for people working on electronics projects.

Anchor Electroncs

Persons in Silicon Valley looking for that last minute part may want to visit Anchor Electronics. Their store-front is at 2040 Walsh Avenue Santa Clara, CA. 95050. Their catalog indicates they have a reasonably wide selection of surface mount and through-hole components, ICs, boards, etc. They can also be reached via telephone at +1.408.727.3693.
