Zocalo coffee shop migrated to digital registers with a solution from square. While these devices are able to process transactions off-line, some types of transactions need the square registers to be on-line. At the time the coffee shop had only one up-link provided by Comcast. Comcast was providing good service at the time, but with the increased demand for the registers to be on-line they needed higher availability.
I live in a a really nice cottage behind the house of my roommates. When I moved in a lot needed to be done to modernize and I took the opportunity to learn more about general construction, electrical installations, and industrial wiring concepts.
I have experience setting up radio transmitting equipment, and make shift broadcasting studios on a shoestring budget.
On the transmission side of things I can fabricate a dipole and tune it with a SWR meter, build a transmitter (if I have a kit and instructions), crimp LMR-400, and have a bunch of techniques for "masting" an antenna and gaining access to line of site.
Firmware was developed for a 8051 microcontroller based transmitter for Free Radio Berkeley. A PLL, keypad / LCD interface, and web interface are dynamically controlled by the micro-controller. The concept of a Terminal is abstracted in the software so that there is code reuse between different IO combinations.
This was a firmware development project for a PIC18F2423 micro-controller based motion sensor for Doug Stock of Digital Structures. The goal of the project is to create a device that sits on off shore oil drilling platforms and monitors the movement of the platform in relationship to the drill. All movement is aggregated and later picked up by Digital Structures Inc.
The Flowershop Collective is a long running artist space in San Francisco. Soon after moving to the west coast I became familiar with the space because of the skate-park that is built inside. The space was under pressure from the city to verify its compliance with local fire regulations in the after math of the Oakland Ghost Ship fire. I responded to a call to the larger community for assistance in preparing for a walk through with the fire marshal.
There are 3-way and 4-way relays on the control panel with sane fail-safes allowing for manual over ride. Setting up this development interface and getting it on the network with a static address was today's progress to having a smarter shack.
Digital Structures is a structural engineering firm in Berkeley run by Doug Stock that specializes in providing structural engineering consulting for offshore oil drilling platforms. Doug Stock has written a massive application in FORTRAN for generating reports about the expected performance of structures provided in different environments.
