Vice President's Report

• working on the de-datacenter machine. got harddrives, need to install them.
• tvb dongle SDR is running at work with gqrx

Treasurer's Report

Here is the financial summary spreadsheet for July 2013: File:HacDC Financials 2013 07.pdf. We gained David Pietrocola as a new member (voted in last month), and prospective members Jeffery Herrity and Robert Ryan-Silva have already started paying dues. Jason Fox and Chris Danicic were voted in as members last month but have yet to pay dues; four other members are delinquent on dues. Graham C., Timothy R., and Nicolas J. (Loki) left. Six people (members and non-members) made non-dues donations.

Project Awesome

Since we only had a surplus of $109.64, I am adding that entire amount to our reserves and declining to declare a Project Awesome dividend for the month of July. Here is the Project Awesome spreadsheet for July: File:HacDC PA Projects-2013 07.pdf. There are currently 15 votes.

Secretary's Report

Nothing to report.

Project SUPPLIES

Total expenditure: ~$120

Replenishment

• PLA filament.
• Copper clad board.
• Spare PCB milling bit.

Expansion

• PLA polishing solvent for silky smooth parts.
• Solder paste.

Unaccounted

• Light bulbs for HacDC DIY projector. Not charging to SUPPLIES unless other HacDC members agree they should be.
• IGBT Modules. We may get 3 of these for $3 each. Usual price is $100 each. Credit to Dan Barlow for the find.

Future

• Building up organized list on the wiki. Please feel free to edit. See: http://wiki.hacdc.org/index.php/Category:PA_SUPPLIES

Requests for Commentary

• Large plastic buckets. Are these within the PA_SUPPLIES project scope? If so, cleanup efforts need them urgently.

Projector

HacDC needs a new projector, ideally 1080p and >5k lumens output.

• DIY is a well-trodden path. Estimate cost around $300 and three weeks, size at 1000mm*515mm*300mm (36"*21"*12") with an 80% chance of high-performance under budget and time. Any unused optics would become core tools in our growing optical lab.
• Commercial-off-the-shelf costs $1500.
• Either way, funding is needed.

DIY

So far, technical design is by me, labor by haxwithaxe, oversight by Dan Barlow.

Progress

• Successful projection with stage light, LCD, and overhead projector lenses.
• Complete light path calculation spreadsheet for redesign.
• Basic optics experiments. Minimum beam expansion with non-laser source and Fresnel lens stacking.
• Prototyping frame (excessively large for future-proofing).

Equipment Requests

A high-power visible spectrum (ie. Ar/Kr) laser would trivialize this project.

Wiki

Most of our expensive equipment is now listed in at Category:Equipment with pictures. Might be wise to link that to the front page.

Dehumidifier

Bought, working, and draining to the outside. Steam pipe opening sealed. (cut on 3 sides to enter, tape afterwards)

Is it sufficient?
