# Summary of #hplusroadmap IRC Discussion (March 25, 2010)

* A philosophical observation was made about SKDB (and similar tools) as "computational praxis" - the ability to act through computer-mediated processes, contrasting with pathological apraxia (the inability to generate processes to reach goals).

* Several open hardware projects were discussed, including DIYLilCNC (an open-source CNC mill with CC licensing), Zoybar (DIY guitar kits), and a Stewart platform for CNC machining built by Dean Mao.

* Jeri Ellsworth's work was highlighted, particularly her DIY transistor doping from silicon wafers and C64 replacement chip design, demonstrating advanced homebrew electronics capabilities.

* Interesting DIY electronics projects were shared, including a homebrew OLED display and glasses with speakers designed to train echolocation abilities.

* A discussion about microfluidic circuit design noted that hand-drawing (via graphical tools) versus using parts libraries involves tradeoffs between speed and the ability to later optimize/simulate designs.

* The GitHub Explorer tool was shared (http://lumberjaph.net/blog/index.php/2010/03/25/github-explorer/), along with a visual fovea test (http://www.pilotfriend.com/aeromed/medical/fovea.htm) that demonstrates human visual perception limitations.
