We have one small posts up on Spaceblimp 3; which briefly announced the planned date (which then channged). We had no post to announce the rescheduled flight or too announce the success of the flight. Is this a problem with people not having access to the site or not willing to post things? <br /> If we are able to aggressively use web + social media, it will build awareness of our brand. This can potentially get us attention for funding from organizations for projects (think for a Spaceblimp 4) once we get 501C3 status.<br /> <br /> Motley Fools used our space to hold their yearly software development meeting. we netted a 400usd donation from that event.<br /> <br /> ==== Katie ====<br /> <br /> == Member Reports ==<br /> <br /> Chris Koepke/Arc Riley - [[ShmooCon Sleepover and Streaming]]<br /> <br /> == Old Business ==<br /> <br /> <br /> <br /> == New Business ==<br /> * Proposal to approve holiday gift of $100 to our excellent security guard<br /> <br /> === New Members ===<br /> <br /> == Adjournment ==<br /> <br /> Adjourned at ___.<br /> <br /> [[Category:Meeting_Agendas]]<br /> [[Category:Meeting_Minutes]]</div>

Perhaps a twitter bot, data visualization heat map or remote occupancy indicator?<br /> # The underlying architecture demonstrates an approach allowing bidirectional communications between many microcontrollers and many application<br /> # The Google Calendar &quot;hacdcdoorman@gmail.com&quot; is updated every five minutes with current occupancy data<br /> <br /> <br /> <br /> == Technical Overview ==<br /> <br /> Martin configured a sensor system consisting of an Arduino, a Radioshack photoresistor (276-1657) and a Quest passive infrared motion detector as shown in the following schematic diagram.<br /> <br /> &lt;&lt;diagram&gt;&gt;<br /> <br /> This Arduino is connected to the jukebox computer via USB and monitored by a simple Python script that forwards occupancy sensor data to a Spread messaging system (see spread.org). Several &quot;agent&quot; applications receive occupancy status messages via Spread and perform tasks such as updating a Google Calendar and data logging.<br /> <br /> All software developed as part of this project is GPLed and available via LaunchPad at: &lt;tbd&gt;<br /> <br /> A demonstration agent is also included in the distribution, providing a convenient starting point for your projects. This demo agent currently toggles LEDs in my house based on HacDC lab occupancy status.<br /> <br /> <br /> == HacDC Doorman Google Calendar ==<br /> &lt;include iframe src=&quot;//www.google.com/calendar/embed?mode=WEEK&amp;amp;height=600&amp;amp;wkst=1&amp;amp;bgcolor=%23FFFFFF&amp;amp;src=hacdcdoorman%40gmail.com&amp;amp;color=%23A32929&amp;amp;ctz=America%2FNew_York&quot; style=&quot; border-width:0 &quot; width=&quot;800&quot; height=&quot;600&quot; frameborder=&quot;0&quot; scrolling=&quot;no&quot;&gt;&lt;/iframe&gt;</div>

(TC)<br /> <br /> == Resources ==<br /> <br /> Bryce L. recently attended our weekly administrative meeting and offered to help with the project. Bryce has professional experience with VoIP, SIP and has offered to help prototype a system using Asterisk with Telephreak services.

<p>Tc: /* Proposed Additional Inventory */</p> <hr /> <div>A sizable inventory of electronic components was purchased for [[Hackersmart]], with the goal that the unsold portion thereof would seed HacDC's electronics lab. This has come to pass, and the components are arranged on a pegboard by the soldering desk. This page is to explain what's available, how much it costs, where to get more, and as a place to request additions to the store.<br /> <br /> Pricing is intended to cover our cost and shipping, and to make the store self-sustaining like the fridge. These are internal &quot;member's prices&quot;, and may not reflect what we charge at conferences, where there's an understanding that purchases actively help HacDC.<br /> <br /> <br /> === Cash Register Departments ===<br /> {| border=&quot;1&quot;<br /> !

<p>Tc: /* Proposed Additional Inventory */</p> <hr /> <div>A sizable inventory of electronic components was purchased for [[Hackersmart]], with the goal that the unsold portion thereof would seed HacDC's electronics lab. This has come to pass, and the components are arranged on a pegboard by the soldering desk. This page is to explain what's available, how much it costs, where to get more, and as a place to request additions to the store.<br /> <br /> Pricing is intended to cover our cost and shipping, and to make the store self-sustaining like the fridge. These are internal &quot;member's prices&quot;, and may not reflect what we charge at conferences, where there's an understanding that purchases actively help HacDC.<br /> <br /> <br /> === Cash Register Departments ===<br /> {| border=&quot;1&quot;<br /> !
