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.
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.
Nothing to report.
Project Awesome Reports
Total expenditure: ~$120
- PLA filament.
- Copper clad board.
- Spare PCB milling bit.
- PLA polishing solvent for silky smooth parts.
- Solder paste.
- 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.
- 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.
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.
So far, technical design is by me, labor by haxwithaxe, oversight by Dan Barlow.
- 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).
A high-power visible spectrum (ie. Ar/Kr) laser would trivialize this project.
Most of our expensive equipment is now listed in at Category:Equipment with pictures. Might be wise to link that to the front page.
Taught about 4 people safe laser cutter usage. Walk-ins welcome Thursday, and random weekend days.
Looking promising. Progress has been made, negotiations are still in progress, may give further details later.
More comfortable headgear and 24bit ADC final assembly underway. These last upgrades promise plug-and-play usability.
Bought, working, and draining to the outside. Steam pipe opening sealed. (cut on 3 sides to enter, tape afterwards)
- Is it sufficient?
