Spruce Goose and other planes

About an hour away from Portland, in McMinnville, OR is the Evergreen Aviation and Space Museum, home of Howard Hughes’ famous H-4 Flying Boat (aka the Spruce Goose) as well as many other planes, rockets, and aviation related artifacts.

The Spruce Goose (made mostly of birch) is enormous.  It’s probably one of the largest planes you’ll ever see in person.

Its 8 propeller engines are puny compared to the wings they’re mounted on, and the plane’s fuselage. It’s hard to imagine that even 8 engines would have provided enough power to move the H-4, but fly it did.

There are plenty of other planes to see in the museum, both military and civilian.

There’s a 21 seat DC-3A (originally belonging to United Air Lines) that you can walk through to get a look at what commercial passenger flight would have been like in the 40s and 50s.

When you need a break from wandering around, airplane seats scattered about the museum provide nice, reasonably comfortable places to sit (and with a good deal more leg room than in an airplane).

The Space Museum takes you through the history of rockets and space exploration, starting with a replica of Goddard’s first liquid fueled rocket, a V-2, a Titan II (used for the Mercury Redstone launches), the Apollo space program, and others. There’s also an IMAX theater (a full-sized one) that shows some pretty good movies. 

There’s a lot to see at the museum, and you can easily spend an entire day and then some exploring all the exhibits both inside and outside.  If that’s not enough for you, go hit the waterpark and slide out of a Boeing 747.

Worth a visit if you’re in the area. Plan on spending at least a half day. Take your time and spend the whole day if you can. Make sure to catch one of the IMAX movies.

Visiting the VintageTEK Museum

During my vacation to Beaverton, OR, I got to visit the VintageTEK Museum with a local friend.  The museum relocated recently to the Tektronix campus, which seems to a fitting place for it to be.

The VintageTEK museum is a pretty cool place with a fair bit of space to show off their collection of old Tek scopes, test equipment, tubes, CRTs and other equipment beginning with an original Tektronix 511 CRT oscilloscope.

Many of the scopes and gear on display are static, but quite a few of them are operational and interactive.  In a side room you’ll also find a Tektronix electron microscope and a Digital PDP8.

A new offering by the museum is an instrument lending  program for students. If you’re working on a project and need some test equipment, you can borrow it from the museum. Available equipment includes scopes, DMMs, function generators, counters, and power supplies.

We also got to see the back area where they have a huge collection of equipment and parts, and where they work on restoring equipment.

Definitely worth a visit if you’re in the area. The museum volunteers are friendly and know a great deal about the equipment in the collection. Their regular hours are on 10AM-6PM Thursday and 10AM-4PM Saturday, but they’ll also open upon request. 

First post + 15 years

15 years ago, my first blog post appeared on the Interwebs!

I was a bit of a late comer to the blogging world. I’d seen people doing it for at least a couple  years or so before this, but at the time it wasn’t anything that interested me. But, then I figured “What the heck, let’s try it out“.

So now here I am, 15 years later.  Probably not blogging as much as I was when I started, but it still provides a good outlet for my ramblings.

Breadboard jumper wire reference

Used an Adafruit Perma-Proto board to make this reference guide for the breadboard jumper wires I’ve acquired recently.

The bottom one has wires from sets that I bought before my local Radio Shack stores closed, and the top ones are from the 700 piece kit from Sparkfun. Since they each used different colours for the various lengths, I thought it would be useful to have a reference guide for what length each colour was.

Bench power supply

A Sparkfun bench top power board kit let me take a 300 W power supply salvaged from a dead computer and use it as a bench power supply.

It’s a handy little kit that takes the power supply motherboard connection and breaks out the +12V, -12V, 5V and 3.3V DC to fused 5 way binding posts.

According to the label on the power supply, it can source 17A at +12V, 0.2A at -12V, 19A at 3.3V, and 15A at 5V. That should be more than enough for any projects I’ll run off it.

I also picked up a few of these simple little 3-digit voltmeters that I’ll connect across the outputs to show the voltages.

Next will be to figure  out an enclosure to contain everything.
