Electrical Wiring

When I was about 8 I help my father build a house that we lived in. This is when I did my first residential electrical wiring work. I did not get back to electrical wiring until I built out my first indoor greenhouse in 2008. Since then I have picked up a few projects here and there. Some day I will go and take the test and ask all of my previous employers to sign off on my electrical work hours.

Smart Shack

I live in a a really nice part of San Leandro along the path of the San Leandro Creek in a cottage behind the house of my roommates.

In the video you see the results of the light being turned on by the pi (analogous to Siemens HMI) in a while loop. Setting up this development interface and getting it on the network with a static address was today's progress to having a smarter shack.

Installing J-Boxes in NOLA

New Orleans has been ravaged by racism and natural disaster (references). It is also a hotspot for traveling punk community and anarchists looking for a lawless place to call home. A few years ago I helped a friend upgrade their existing solar electrical wiring, and recently visited hoping to continue those efforts. No hep was needed there, but I was able to lend a hand at the other anarchist squat across town by repairing a "knicked" wire with a code-compliant J-Box. While this was not much work I did take the opportunity to audit the wiring done there by a real professional.

DTMF Door Entry System

The St. James Infirmary office at 234 Eddy St houses a number of workers, supervised programs, and clinics throughout the week. During the office peak hours the front door is staffed by a security guard and the front desk is staffed by an administrative assistant. During off-peak hours additional managed door access control functionality was needed. Viking Rugged E-30 intercoms alongside Viking SRC-1 relays were chosen as a solution to allow staff members to use the existing phone infrastructure to screen people at the front door and use a password to buzz people in.
