October Things To Do – San Diego, CA   Leave a comment

October 3 and 4: Maker Faire® San Diego!

Wayne Yoshida Technical Writer-ExhibitSheet

Maker Faire San Diego is October 3 and 4, 2015, from 10 AM to 6 PM at Balboa Park. Our “Not Your Grandpa’s Ham Radio” theme will feature some new projects as well as some of the old, but popular demonstrations from previous Maker Faire events. Pictured below is a project under construction, I hope to have it completed for this event. It is a homemade 1090 MHz collinear (vertical) antenna that will be part of an air traffic control monitoring station using a software defined radio (SDR).

October 15 to 18: Microwave Update (MUD)!

Microwave Update, or MUD, is a yearly technical conference for amateur radio experimenters making, modifying, hacking, building, testing and using the 1,000 MHz and up radio bands. Participants from all over the world gather at these events to share information about operating techniques, radio propagation and radio station equipment. One aspect of this event is the buying, selling and trading of surplus parts and assemblies for these frequency bands, since some items may be difficult to procure in some areas. But perhaps the best thing about MUD is socializing and making new friends from all over the world to discuss common interests and goals.

Preparations for the San Diego MUD are still under way. Last weekend, a few San Bernardino Microwave Society (SBMS) members gathered at Dave’s lab to sort and package some prize and give-away items for the event.

I hope to see you at any or both of these events!

Arduino Radar Shield at Maker Faire Bay Area 2014   Leave a comment

This radar system operates at 2GHz (S-band). The Arduino stack consists of a radio front end, controlled by an Ardunio Uno and signal processing is performed using an Arduino Due. A Bluetooth link moves the data from the radar system to the notebook computer, where the radar information can be seen using a “waterfall” visual display.
