Treasurer's Report

Here is the financial summary spreadsheet for September 2013: File:HacDC Financials 2013 09.pdf. We gained two new members in September: Alex, who was voted in at September's meeting, and Brendan, who was voted in in August.

Project Awesome

Here is the Project Awesome spreadsheet for September: File:HacDC PA Projects-2013 09.pdf. I'm declaring a $500 Project Awesome dividend, with the remaining $129.54 of the month's surplus going to our reserves. There are currently 17 Project Awesome votes.

Project SUPPLIES

Financial Outlook

Healthy to say the least. At nearly $1k and rising, budget is sufficient to cover most major equipment failures at HacDC. After SUPPLIES budget hits $1k, further allocation to it should probably be reduced to a trickle.

Future Plans

  • Spare hot-end for Prusa Mendel.
  • Better glass bed for Prusa Mendel with predrilled holes.
  • Large plastic buckets.
  • Possibly new PCB fab supplies, like CNC milling bits.
  • Possible expansion of parts store, after some clean up at HacDC.

Occupancy Sensor

Easily returned to fully operational status, an even more reliable solution is imminent.

Biohacking

Imagnus

Going well. Obtained permission to discuss some of the details of these arrangements. Although nothing has been signed yet, it seems reasonable to keep their concerns in mind.

NDA

We have negotiated very fair, acceptable, and open-source friendly terms.

  • Wide latitude to use, distribute, relicense, etc, our own technologies with a few very specific provisions. Basically, we agree not to commercialize a directly competing product as defined by a narrow FDA category, and not to publicly mention Imagnus's connection to the technologies.

Basically, we retain rights to key technologies for our projects.

  • Non-transferable. Automatic expiration on conditions that may amount to corporate takeover. Put another way:

There are literally several levels of SCO being wrong. And even if we were to live in that alternate universe where SCO would be right, they'd still be wrong. -Torvalds

This shall not happen to us.

  • NDA expires in two years.

Important lessons have been learned negotiating the NDA that probably should be applied to similar arrangements in the future.

Expected Benefits

A few hundred dollars, probably soon. Royalty payments, probably much more significant.

Status

The project is complex, and we are making excellent progress.

Biosignal Amplifier

Revised design for 24-bit USB ADC board. This will soon be merged with the host board, tidying up the biosignal amplifier, and giving it a USB port.

Additionally, the standalone ADC will likely make it to the test cart, providing extremely high resolution signal capture and processing capabilities.

See github for the standalone USB ADC. USB DAQ.pcb.png

Projector/OpenDisplay

We still need three giant Fresnel lenses from rear projection TVs. A HacDC member recently obtained two of these from Craigslist. We need three more. Project is stalled until we get these lenses.

Design/OpenSource

Just a reminder, the design is published, with CAD models, as OpenDisplay.

PCB Fab Efforts

Have been trying to fabricate professional quality circuit boards, with 6mils or less isolation widths, and no excess copper. So far, almost acceptable results have been achieved using the laser cutter with fingernail polish resist and chemical etchant. More still to be done.

ToDo Tracker

An experimental project/task management application using web2project has been created for HacDC members and guests. Please see HacDC Projects.

HacDC Shelves

Designed for HacDC Basement. Intended for placement a few feet away from wall in both rooms, accessible from both sides, providing a sort of warehouse. 8' high, 16' long, 4' deep, 16" elevations, density-optimized reinforcement. $264.99 for 384 sq.ft. at $1.44/sq.ft.

Recommend we allocate $600 for two of these shelving units, one in each room. Also recommend someone besides myself build them (eg. haxwithaxe), which shouldn't take more than a day.
