Here is your chance to earn some minutes of fame – and show off that secret project you’ve been working on in your garage. . .
Deadline for proposals is March 15, 2013.
I entered last year. Our theme was “Not Your Grandpa’s Ham Radio!” and generated a lot of interest in our radio clubs.
More information on this year’s event is posted here.
Take a look at some videos from my previous Maker Faire experiences…
My favorite videos from the MakerFaire include a short chat with Jeri Ellsworth and her “key-tar.”
Jeri has some very interesting YouTube videos, too.
And take a look at the giant paella pans cooking away!
The San Bernardino Microwave Society (SBMS) had a Christmas party this past weekend, and it was a good break from doing sheet aluminum work. The event seemed smaller this year, several of the usual suspects were not able to make it. There was lots of food to share and gifts to exchange. Happily, regular guests Mel WA6JBD and his better half, Tisza KI6DBR came and brought their usual homemade treats, including Tisza’s famous chocolate truffles, microwave dish cookies and a chocolate sculpture. This year’s sculpture was a 10GHz horn and a section of waveguide. And yes, they really do work at 10GHz. Mel measured the return loss of the horn and waveguide and reports more than 17dB or something like that – pretty respectable for an edible 10GHz antenna.
Here are some pictures of the event. . .
Where else but a ham radio Christmas party would one find a 10GHz horn and waveguide made of chocolate – that actually works
Tisza’s homemade chocolate truffles – Yum!

What in the World is That?
After the party wound down, I stayed to get a closer look at Dennis’ new camera. It does not look anything like a camera, but it really shouldn’t because it makes images in a whole new way and enables a whole new way to enjoy still images. I thought it looked more like a kid’s kaleidoscope, rather than a camera.
The camera and lens system optics look very simple. And that is one of the points: You do not need fancy telephoto or macro lens capability. It is done in software. There are no fancy controls or buttons, only soft pads on the rubberized parts of the case. There is a power switch, a zoom control and a shutter release. An LCD with touch screen is on the back. Here are some pictures of this new gadget.
WHAT is THAT!
The Lytro camera. At left is the lens cover, it attaches magnetically. That’s an item that will be lost immediately. Center, the camera, showing the front glass and lens. Right – a tripod adaptor.
As I mentioned on my LinkedIn update, the Lytro camera introduces a paradigm shift in the way we can look at still pictures (pun intended, sorry). At first, I thought this camera simply used some sort of image processing to “fix” images, simple things like contrast and color adjustments and maybe some image manipulation, like PhotoShop. But then Dennis said that you can change focus and “raw image” features, like zooming in – after the image is stored on your computer.
The images are not jpg or other familiar formats – but then – these are not ordinary images, either. You can actually change the depth-of-field – change the point of view of the image.
Watching some of the demos on the Lytros website made me think of scenes from the TV show “CSI:” because you can see an image captured by the camera, and you can actually zoom and move around the various places on the image, and see what else the camera captured.
Visit the Lytro website, pictures and demos and details are worth closer examination. Unfortunately, I don’t have any Lytro images to share – yet.
The Coupe Goof
The day after the party, I went back to work on the Coupe. Something bothered me as I looked at the images and some postings of other builders. The driver’s side footbox and the front, where the pedal box mounts, looked different than mine. And I found another driver side footbox front panel in my box of aluminum parts. I looked at the part number of the “extra” footbox front (15312) on the packing slip, and noticed the description: “Driver Footbox Front Wall, Coupe Wilwood Pedals.”
Argh. Since I have the Complete Kit, it came with a Wilwood pedal box. Part of the confusion is the way Factory Five Racing packed the sheet aluminum – the major parts are held in place on the chassis and are shipped in place. This would be fine for the builders using a donor Mustang pedal box, the “Basic Kit” version.
So, I had to remove the driver side footbox front panel and replace it with the proper one. The good news is that I had all these things in place with Cleco fasteners, not rivets and silicone. And, I used the old panel as a drilling guide for the new panel. Now I have a spare sheet of aluminum I can use for – something. Hatch covers, maybe.
On the left is the wrong driver side footbox front panel. This is the one that is shipped in place on the chassis. The one on the right is the front panel for the Wilwood pedal box. Good thing I didn’t silicone and rivet that panel!
Disaster averted – the wrong footbox front panel was removed and replaced with the correct front panel for the Wilwood pedal box.

One fact in Glenn’s article needs correction:
ARRL is the American Radio Relay League. I worked there in Newington, CT many years ago…

Okay, I finally started a WordPress blog. I will be sharing topics I enjoy – from Amateur (ham) Radio and serious barbecue, to writing and editing.
A New Project
I am just about ready to move from the “Planning” stage to the “Ordering” stage in my latest project: Building a Factory Five Racing 65 Coupe. I have been thinking about building one of these even before I had a drivers’ license! A great sale is on this month – 50% off all accessories – so I need to finalize my configuration and place my order in less than two weeks.
The picture above (from a 3/22/12 post by vnmsss on the Factory Five Racing forum) is what I am talking about…. and is the color scheme that is close to what I have in mind – although I want black competition stripes.
Building a kit car will take two years, so this will generate a lot of content on this site!
