Acme traffic light restoration

The Southern California Transportation Museum is one of the largest private transportation museums in the United States. We are privileged to have among our artifacts a set of Acme traffic lights. This type of traffic signal was deployed in the Los Angeles area in the 1920s and 1930s. This was the time when every city was experimenting with different types of traffic signals. Later the Automobile Club convinced everyone to adopt the three-light signal they use today. During the brief time they were in use, the ACME traffic light became the favorite of the Hollywood cartoonist so, that’s why you see them all over the movies.

Testing circuit board for Adafruit’s FONA808 module

Jesus Echavarria from Spain has tipped us off about his latest experimenting circuit board. This time he has made a testing circuit board for Adafruit’s FONA808 module that carries SIMCOM manufacturer’s SIM808 GSM and GPS transceivers. The Adafruit board includes this module and also some electronics for choosing voltage levels, battery connection and charger. Because I need to test and programming some of this modules, I decide to make an specific PCB for it, allowing the programming and debugging via PC, wich is more comfortable that use a microcontroller for all these tasks. I use the MCP2221 USB-Serial bridge and
