From what it looks like, if anyone wants to build one they'll need:
- An IC (the one he used seems to be http://www.ebay.com/itm/5-Rare-Vintage-GOLD-NEC-044-D4164D-4164-64k-DRAM-RAM-16-Pin-IC-Cer-DIPs-Japan-/331025114689 http://www.ebay.com/itm/5-Rare-Vintage-GOLD-NEC-044-D4164D-4...)
- A small lens to place over the IC (http://www.ebay.com/itm/MTV-6MM-CCTV-IR-Lens-For-Security-IP-Camera-/170701642765?pt=US_Surveillance_Accessories&hash=item27be9c5c0d http://www.ebay.com/itm/MTV-6MM-CCTV-IR-Lens-For-Security-IP...)
- A parallel to USB cord if you don't have a computer with a parallel port (http://www.ebay.com/itm/USB-to-PRINTER-DB25-25-Pin-Parallel-Port-Cable-Adapter-/190385076507?pt=US_Parallel_Serial_PS_2_Cables_Adapters&hash=item2c53d5b91b http://www.ebay.com/itm/USB-to-PRINTER-DB25-25-Pin-Parallel-...)
Please correct me if I'm wrong about any of these parts - I haven't tried to build one myself.
Here's my rudimentary understanding of the pin connection: (to connect it yourself, use https://upload.wikimedia.org/wikipedia/commons/b/b3/Pin_numbering_01_Pengo.svg https://upload.wikimedia.org/wikipedia/commons/b/b3/Pin_numb..., https://upload.wikimedia.org/wikipedia/commons/e/e0/Parallel_port_pinouts.svg https://upload.wikimedia.org/wikipedia/commons/e/e0/Parallel..., and https://upload.wikimedia.org/wikipedia/commons/e/e1/25_Pin_D-sub_pinout.svg https://upload.wikimedia.org/wikipedia/commons/e/e1/25_Pin_D... as guides)

- yuubi 13y ago> parallel to USB Last time I looked at the spec for those, it supported send-byte-to-printer-with-IEEE-1284-handshaking as a primitive (the USB interface saw data bytes, not instructions to set, clear, and read control lines). The parallel ports that attached to ISA (or inside PCI multi-I/O chips) connect each pin to a bit of an I/O address in compatibility mode[], which connect-a-chip-to-parallel-port hacks tend to use.
