Maker Faire 2015 Recap – Part 2   Leave a comment

Since pictures are worth a thousand words, here is a 2015 Bay Area Maker Faire recap in images from and around our Not Your Grandpa’s Ham Radio theme booth.

Click here to see the official Bay Area Maker Faire video from 2015

The Bay Area Maker Faire 2015 team: Team Leader Brian Yee W6BY and his wife Pat and daughter Stephanie, Dennis Kidder W6DQ, Lisa Gibbons KF6QNG and Paul Zander AA6PZ

We had working, hands-on ham radio projects including Brian’s (W6BY) 10 GHz ham radio transverter system, a radio-controlled tractor/forklift (ZigBee controller) and the big screen used as an electronic sign.

Dennis W6DQ brought several brand new projects this year, including a working Amateur Radio broadband (WiFi) network with seven nodes, a software-defined radio (SDR) system.

I brought a demonstration comparing old and new technology in antenna tuners. It uses light bulbs for a substitute (“dummy”) antenna.

 

 

There’s so much to see and do. Here are some pictures of what I get a chance to see.

 

Always great to see Tenaya promoting Arduino and Arduino related projects and products!

Intelligent Infrared Sensors at Bay Area Maker Faire 2014   Leave a comment

 

University of California, Davis engineering students  Sam Dawson (left) and Andrew Chung (right) demonstrate their engineering project at the Bay Area Maker Faire. The microprocessors in each box are equipped with infrared sensors and emitters that “talk” to each other and glow different colors to indicate their relationships to another box.

The project provided hands-on experience in both hardware and software to supplement lectures and textbook learning.

Watch the video on YouTube Channel KH6WZ.

Here are some amazing photos of Anouk Wipprecht and some of her costumes at the Maker Faire Bay Area. The photos were taken by Kyle Cothern of CrashSpace, in Culver City, CA

In these photos, you can see lightning effects created by a giant Tesla coil, made and “played” by ArcAttack!

Maker Faire 2012-2 010

 

 

The big show is coming soon. Last year, over 120,000 people attended this science-art-food-engineering-fun-educational event.

This year, my team (Dennis Kidder W6DQ, Brian Yee W6BY and Marty Woll N6VI) will bring their newest ham radio projects to show. We will continue with my original theme called “Not Your Grandpa’s Ham Radio.”

A group of University of California, Davis (UCD) engineering students will join us to demonstrate their experiments and projects. These new engineers are getting a great head-start by doing hands-on, practical experiments and projects that go beyond their lecture and textbook learning.

OC Mini Maker Faire 2013 Recap   Leave a comment

FindU.com APRS display of the KH6WZ-5 location beacon at the 2013 OC Mini Maker Faire at UCI

APRS display of the KH6WZ-5 location beacon at the 2013 OC Mini Maker Faire at UCI. Notice the beacon message at the top of the screen capture includes the URL of the event – a great publicity tool!

This past weekend, the second OC Mini Maker Faire happened. And it just so happens to be the second running of my ham radio demonstration called, “Not Your Grandpa’s Ham Radio (2)!” This is my continuing mission to remind people of two things:

First, “The Maker Movement” is nothing new, Amateur Radio operators have been doing this for a almost a century, and nearly 2 million people worldwide are involved in ham radio in some way.

Second, Ham radio is not necessarily an old man’s hobby where weird guys talk to strangers from garages and basements. We are skilled wireless communicators and use today’s technology, from GPS and microprocessors to lasers and microwave frequency linking.

This time I added static and working displays of my various APRS beacons (KH6WZ, KH6WZ-5, and others). I programmed the OC Mini Maker Faire’s URL to the beacon message so people can take a look at what was happening – an excellent publicity tool!

I also planned on making some 10 GHz contacts with my rig, since this was also the same weekend as the ARRL 10 GHz and Up Contest. The transverter covers were removed so people can see the system’s guts.

Based on previous experience at the Discovery Science Center “Meet the Makers” event, I demonstrated radio wave polarization- horizontal vs vertical – with my rig and the microwave strength meter.

Since I had plenty of space, I shared my booth with a company that makes interesting computer and microprocessor related items. This may sound trivial, until you realize this company is run by these three young guys . . .

There seemed to be more people at this Faire, probably since not too many other events were happening nearby. The 405/605/22 freeway closure did not affect the MF, since it started after the event ended.

More than a dozen hams – either active or at least licensed – stopped by to visit. We talked about this event as well as the Bay Area Maker Faire, and what ham radio activities we are involved with.

One more thing: I met several guys from the San Diego area – they are finalizing the plans to have a Mini Maker Faire in the San Diego area – this is great news. Stay tuned and I will announce an update as soon as I hear something from the committee!

Here are some pictures from the event. I am already thinking of building some new displays for next year.

Type 65 Coupe Update: E-Brake Handle, Fitting the A/C and More IRS – and Maker Faire 2013 Application   Leave a comment

I got tired of fiddling with the IRS so I did something different this weekend. Here is a picture of the E-brake ratchet handle that comes with the Complete Kit. Since the parts are plain, un-finished steel, I decided to paint it to prevent rust. The exploded view in the instructions make assembly very easy. I wish The Factory would include an exploded view for the IFS as well as the IRS – makes things go so much better. The finish is white and black appliance epoxy from Rustoleum.

Here are some pictures. . .

I am not sure if I like the location of the E-brake handle, it is on the passenger side of the transmission hump. A popular modification is to use a Pontiac Fiero unit and re-locate it closer to the driver. We’ll see if I want to change this setup. (The sharp-eyed people will notice the e-brake handle is backwards. . . . . . )

Here are some images of the air conditioner and a cardboard aided design (CAD) templates I am making. This requires some cutting of the dashboard and firewall, so I want to mock everything up before I start cutting. I have some very sturdy aluminium plates for the A/C baseplate, and some sheet aluminum for the enclosure. A CAD version will be made first, then transferred to aluminum.

Moving back to the IRS, I received some advice from the veteran builders, and so here is what I did to the lower control arm mounts. The shims (thin black steel washers) F5R supplies are slipped into place and some adjustment is done by placing shims here and there. However, it makes more sense to limit the toe and camber adjusters so that the tweaking can be as simple as possible. By “fixing” one side of the control arm, and limiting it to one adjuster for toe and one adjuster for camber, alignment is simplified and less time consuming.

Currently, this stage is to just “eyeball” the adjustments, and continue the build process. Wheel alignments – both front and rear – may be done after the wheels and tires are mounted. (Probably can be done at the “go kart” stage, when the chassis is complete and the engine, drivetrain, electrics and brakes are installed and running.)

Here are some pictures. As this step gets closer to completion, I will add more details for future reference.

Above right: Here is the trick I use to install slippery washers, shims and spacers onto things – Use a punch or some other tool to poke through the stack of parts together, thus aligning the holes of each part. Then . . .

. . . push the fastener – and the punch – through the stack of parts. Wiggling, pushing and pulling will help. Sometimes a quick-clamp can help, too.

Maker Faire 2013 Update: Application is In!

I turned in an application for Maker Faire Bay Area 2013. Our Maker name is “Not Your Grandpa’s Ham Radio 2” and we will continue the theme my team entered last year. We will have some new projects on display, and we will bring some of the more popular items from last year. Here is a look at some of our projects from last year – as well as some other interesting and amazing things I saw last year.
