-California is a massive state with many people who are members of this well-known group, so it's likely that many people have questions as to how this could affect them. As of right now, it's not really known. There aren't really many details available on what could result from such a move.
+====== The basic idea ======
-The Supreme Court ruled in 2000 that it was okay for the Boy Scouts of America to discriminate against homosexuals due to their freedom of association. Nonetheless, this new approach of going after their tax exempt status might have a different outcome. The group famously considered lifting their ban on gay members earlier this year, but their decision has been delayed—and understandably so. This is a huge decision to make regardless of how much of a no-brainer it might seem to the rest of the country. [[http://vienne.co/gio-xach|gio xach]]. Indeed, this is a sensitive situation, but all in all, children shouldn't be discriminated against. And if a private group is going to discriminate against children, should they really be exempted from paying their fair share to the government? In a , their lack of tax payment kind of makes it look like the government condones their behavior.
+gcc/binutils/etc : software engineering :: lindsay : mechanical engineering :: **openbench : electrical engineering**
+Entire project consists of 6+ bench tools (definition here?) pretty much everything except a DMM (no point to doing it, so cheap) to create a platform for development, possibly speeding up the 'fab lab revolution' a bit
+Tools are optimally available in 1-3 configurations : basic/low cost, better/medium cost, best/highest cost
+I've been talkin' about this for 2 years now, and I expect it to take about 2 more years to get first revs done
+====== Licensing ======
+Completely open source from mechanical (DXF), to hardware (schem, layout), to firmware (CPLD/microcontroller) to software.
+(Read more [[http://www.ladyada.net/resources/openhardware.html|here]])
+either Creative Commons, GPL, MIT, BSD or a mix
+Contains only out-of-patent or unpatented technology
+====== Constraints ======
+Low cost, off-the-shelf, in production parts only.
+DIP, PLCC, thruhole preferred. SOIC, 1206 passives and other large SMT "ok". No SSOP, QFP, LLP, uSOIC, etc.
+  * Projects must be configurable as standalone (no "USB only") with LCDs, controls.
+  * Computer connection preferred, but no parallel ports. Serial ports "ok". USB preferred.
+  * Nice enclosures, preferrably from Hammond or Pactec. Should be easy to machine (with dremel, drill) or with laser cutter. No woodworking, or vacuum forming. Machined enclosures will be available to purchase
+  * PCBs are double sided only. Standard FR4, 1oz copper, 10/10 rule. Don't have to be etchable (but would be nice). Final PCBs will be available for purchase
+====== Projects ======
+All are still in part spec/planning
+   * [[psu|Adjustable DC power supply]]?
+   * [[lcrmeter|LCR meter]]
+   * [[fgen|Waveform generator]]
+   * Frequency counter
+   * Logic analyzer
+   * Oscilloscope (the holy grail!) //Rather than starting from scratch, start with one of the open-source oscilloscopes that already exist -- http://opencircuits.com/oscilloscope#Open_Source_Oscilloscopes .//
