Linux

Oh Linux… sometimes you make it really hard to love you.

While the recent data rescue went well, other things have not been as easy. Let’s see where we are, shall we?

Home Server
This is the old dead-screen PowerBook that ran for years without issue. Until it had an issue. I rescued the data from it, and then I figured I would do a re-install of Linux on it, but so far it’s been all failure. The external VGA connection doesn’t seem to want to display anything, so without a screen to see the install, I don’t even know if it’s booting up properly. (This is a recurring theme, btw.)

Raspberry Pi
One of my Raspberry Pis occasionally hangs on boot. Sometimes. Other times it works fine. Since it’s headless I needed to attach it to a TV to see this. The other Raspberry Pi I have does have an HDMI-VGA adapter, which works when you edit config.txt properly. Sometimes. And yeah, my RF Modulator to use the composite video seems to have died, so that option was out as well. Also, the SD card cracked. These are all fairly minor things, but they add up.

(New) Xubuntu Laptop
While it’s a new machine to me, it’s a 10 year old laptop running Xubuntu. It was going to be (will be?) my new Lab Computer, controlling the RepRap, and hopefully running Octoprint, which won’t run on the Eee PC I now use to control the RepRap. I left it running with my account logged in and it went offline… kernel panic. Hmmm, let me check right now. Yeah, it’s hosed up. I try to ssh in and get ‘Input/output error’ so something isn’t right. Dammit.

Eee PC
Well, this little beast keeps chugging along. Besides the fact that it can’t do much, it can control the RepRap, and it does a pretty good job of not losing the wifi connection. All good.

Another One
Since I may need a replacement for the old PowerBook that was the Home Server, I figured I’d try an old G4 iMac with a dead display. Multiple attempts with Ubuntu Server and Xubuntu Desktop all failed. Won’t boot from a CD or DVD. I did read about an NVIDIA driver conflict, urgh. I may try some other distros, but I’m thinking it may be an issue with the fact that the built-in display is dead and the external VGA connection isn’t doing the right thing. Bummer.

Keep in mind I’m considered really good at this stuff… but I guess when shit goes wrong, it really goes wrong.

RepRap Cat

I’ve already talked about the Top 5 Places Kitten was, but since kitten (who is now a cat, and sometimes referred to as RepRap Cat) spends a lot of time in the office with me, I thought it was time for a new list…

The top 4 Macs kitten has sat upon:

  1. MacBook Pro
  2. Mac mini
  3. G4 PowerBook
  4. Mac Pro

She also spends a lot of time on the printer, which isn’t a Mac, but has a lot of buttons to press.

The only Mac missing is the iMac, and that’s because she hasn’t figured out how to sit on top of that one… yet.

Update: I snapped this picture less than two hours after posting this.

Last year I was invited to a co-worker’s wedding. And, since so many weddings nowadays involve being creative on a budget, they had a photo booth there that they set up themselves using Sparkbooth, a great little Adobe AIR-based application. A few weeks later we were having our annual work party, and I was tasked with making a photo booth a reality. Since then I’ve been working on building a better photo booth experience.

For the first one I set up, I used my MacBook Pro. We connected a Sony PD-150 video camera via FireWire and selected it in Sparkbooth rather than using the built-in iSight camera. (The iSight is a small camera, with a tiny lens, so the video camera ended up providing a better image.) We also put a little sticker on the space bar that said “PRESS HERE TO TAKE PHOTOS” and hoped for the best. It worked, but there were just too many moving parts to deal with, like the camera on a tripod behind the MacBook, and a light clamped onto the tripod. It wasn’t elegant.

The Sparkbooth software is great and provides a ton of features, including the ability to upload photos to Flickr, Facebook, Tumblr, Posterous, or a dozen other sites. There are some optional features that would require a keyboard—if you prompt people to enter their name, email, a comment, or choose if they want the image uploaded or not—but the main interaction is through pressing the space bar to start the picture-taking process.

If you need a space bar, you may need a keyboard… unless you build something that can emulate a space bar. When I saw The AWESOME Button on Make, I knew what I had to do. I had to build a button.

Ready for Pushing
The Button

The button is simple, and built into a metal case. It should stand up to abuse that a normal keyboard might not, and it’s pretty simple. You can’t really press the wrong button, there’s only one.

Once I had the button, I set about getting my old iMac set up as the photo booth machine. Not being happy with the built-in iSight (the iMac is about 4 years old, and it’s definitely not as good as the latest round of iSight cameras), I ended up taking the Canon ZR800 from Time Lapse Bot and using that. It worked OK but wasn’t ideal. I didn’t want to have to deal with a tripod and more cables, etc. (I even ended up testing a floor-mount camera holder I built which took pictures of shoes for a specific event—don’t ask!)

Ultimately I settled on using a Logitech HD Pro USB Webcam C910. Its image quality is much better than the iSight, and there’s just one cable to plug in. Just one problem… while it worked fine with my MacBook, no matter what I tried, I could not select it in Sparkbooth on the iMac. I tried everything, including different versions of Adobe AIR, different versions of Mac OS X, reformatting the drive, a clean install… nothing would work. I ended up disconnecting the built-in iSight thanks to some help from iFixIt.

The Photo Booth
The Completed Photo Booth

So I now had the button and the camera. I then needed something to hold it all together. I wanted a stand to put the iMac on that was about the right height for a “typical human being,” and by that I mean: about my height. (You can also easily adjust the camera by just tilting the iMac a bit.) I ended up building a simple pedestal out of plywood and painting it white. I used thin plywood to save on weight since it needs to be somewhat portable. You can’t see it in the photo but the back has been left open, and there’s an internal shelf for the keyboard and mouse. I keep those handy in case of trouble, or if I need to change any settings in the software. The shelf actually helps structurally as well.

For the light, I used a small IKEA clamp light (you’d be amazed how hard it is to find a small, good-looking clamp light.) There’s an L-shaped piece of plywood behind the iMac that’s held onto the stand with a c-clamp. It works for now. I may upgrade the light in the future.

Booth Photos
Photos from the Booth

Here’s a selection of photos from the first official use of the Photo Booth. (Yes, there are two Munchkins on the back wall—it was a “Wizard of Oz” themed party.) I’m asking for a bit of forgiveness in calling this a “Photo Booth” at this point because, while it does take photos, there isn’t an actual booth yet… I need to save something for Phase II of this project…

Stay Tuned!

Remember two months ago, when I got a new iMac? Well, I got a phone call from my brother-in-law saying he was on his way to the Apple Store to pick up a new 20″ Apple iMac.

Apple iMac (New!)

So we’ve got the same computer now! Well, except that in that two month span, Apple redesigned the thing and speed bumped it. For anyone new to the platform, that’s the way Apple works. Get used to it.

The last time my brother-in-law bought an iMac, Bondi Blue was a hot new color…

Welcome to the future!

If all goes well, I should have a new 20″ Apple iMac in a few days.

Apple iMac

It’s really time for a new Mac. I mean, I probably would have kept on using my G4 for another year or more if it had not died. The last time I bought a new computer was 2001. I even got AppleCare this time, because honestly, I don’t think Apple builds machines as good as they did 6 years ago. (Definitely not as good as they did 10 years ago.) Anyway, I can’t wait to get it and see what it can do. Of course now I need to worry about Universal Binaries and all that Intel related stuff. (A quick check shows that a good number of apps I use daily already have Universal versions.) But honestly, even if the PowerPC apps run slow, they should still be faster than the old G4 was running them. I’ll let you know once I run it through it’s paces.
