Financial Outlook

Awaiting spreadsheet.

Recent Purchases

  • 2 1kg PLA Filament Spools
  • Glass cutter, several glass sheets.
  • T25 Torx Bit

Prusa Mendel

Bed leveling issues became an increasing nuisance, due to a lack of suitable glass and clamps. Using dremel tool, glass cutter, and laser cutter, I have finally created a multilayer through-hole mounted glass bed.

This took weeks of experimentation and shattered glass that would have been much easier if we already had a wide-area CNC built on the optical table.

Future Plans

After cleanup at HacDC, can consider improving generic supplies like mill stock, electronic components, laser cutter stock, and hardware (ie. screws).


Financial Outlook

Awaiting spreadsheet.

Future Plans

As noted on the Project Tracker, Vertical Bandsaw and Server are top-priority items.

Vertical bandsaw has been specifically cited as an example of the kind of metal/wood/plastic working tool required at HacDC.

High-end VM server will be used to PXE boot the WYSE terminals into high powered computers.


Member Reports


Occupancy Sensor

Working reliably.



We may need to recruit more participation from other HacDC members soon, and the compensation structure for me and HacDC is still being worked out.

Also, a lot of interesting progress is being made.

Biosignal Amplifier

All the hardware is in place, usage will soon be simplified to a USB plug-and-play device. GNURadio has proven insufficiently flexible, and a new rapid prototyping environment called SigBlockly is under construction.

This environment will allow graphical 'drag-and-drop' development of DSP C programs, similar to, but much more powerful than blocklyduino.

Thursday Meetings

The Thursday biohacking meetings have been getting quiet, but the core members still occasionally drop by and express interest. With the biosignal amplifier nearly finished, and hopefully more tools deployed at HacDC, we should be able to resume other projects.


Still need 3 more giant fresnel lenses from old projection TVs craigslist.

Also, a modular pallet-and-rail will be used for the optics this time. The prototype frame that has been taking up space in the workshop is no longer needed, and will be disassembled.

Flex Replicator / Optical Table CNC

Soon as the Optical Table is on its feet, will outfit it with gantry hardware, and a variety of tools. This is compatible with the Flex Replicator, but much larger and more accurate.

We will then be able to mill out the kind of large parts that have recently been hand-crafted at great expense and labor for our 3D printer, and laser cutter.

This should be top priority. At least 75 hours have been lost due to lack of this capability, and projects are waiting on it.

myDAQ and myDSP

Special thanks to Ahmed Aden for making a special trip to bring the myDAQ and myDSP back to us.

Old Business


$600 for shelves to mirage.

Honorary Memberships

The Doctor

The Doctor is one of the founding members of Project Byzantium and one of the largest contributors to the project. He has made numerous other contributions including donating time and equipment to improve the space, and helping us to network with other individuals and organizations with shared interests.

R. Mark Adams, PhD

Long time member and contributor to the space.

New Business

  • Zach purchased materials for basement shelves, and should now be reimbursed up to $400.
  • Approving another $75 will allow wheels to be added to the shelves.
