XLH-3800 Barcode Scanner: Linux Compatible

The XLH-3800 laser barcode scanner is powered by a USB port and pretends to be a keyboard. (It “types” the codes of barcodes when you scan them.)

I am happy to report that this (generic) laser barcode scanner works out-of-the-box with Linux (Tested on Ubuntu 9.10 and 10.04), and does not require any module configuration like the ACAN FG-8100 barcode scanner.

The XLH-3800 is a true laser barcode scanner, meaning that it throws a rapidly scanning laser dot (100 times per second) out into the world, giving the appearance of a laser line. This increases the read range when compared to a CCD scanner, and gives a visual indicator of where to point the device.

Mysterio Fog Generator

One foot of 4" pvc pipe, with a 3 way T on the top, painted green. The grand plan for my Mysterio costume is to have a backpack worn fog generator using dry ice. (I’m not sure I’ll have time to get the fog generator or the strobe lights working, as I don’t even have the jumpsuit or boot covers finished yet, but I had the PVC parts so I started work on it.)

The Plan: Have warm water in the pipe–possibly with a loop of plastic tubing wrapped around my torso fed by a pump, which would have the dual effects of keeping my special effects water near body temperature, and cooling me off, which is important in Atlanta in the summer. I’ll have a basket of dry ice inside the tube that can be lowered using string, and a fan blowing air down the top of the pipe. The Dry-Ice Fog will billow out the sides of the T pipes and look really cool emerging from under my cloak. (How I wear the fog generator is not yet part of the plan, but I’m imagining something like a backpack, or suspending it from my cowboy collar.) It will be mostly hidden under my cloak, but since I had the emerald green spray paint left over from my color matching paint buying discovery, I decided it should be color coordinated.

4" PVC pipe, a 4" knock out cover, and a 3" to 1 1/2" four way adaptor - All parts used to make my fog generator Fog Generator parts fit together.

Cost saving measures: I bought $5 worth of PVC parts (a 4″ piece of low pressure tube, a “knock-out” cap to seal the bottom, and a 3″ to 1 1/2″ 4-way adapter. By using the $1 knock out instead of a full 4″ PVC cap I saved several dollars and made the bottom of my fog generator “flat” instead of rounded. As it will not be under any pressure other than the weight of the water and dry ice, it should hold fine. [And if it doesn’t, I always have my “Uh oh, I think my water just broke” joke all lined up.]
I also saved money (and bulk) by using a 3″ 4-way adapter, instead of a 4″ one. A 3″ PVC pipe will fit perfectly inside of a 4″ PVC pipe if you rasp off the small protrusions. (The fact that I was informed of this by a “plumber” also shopping in the Home Depot plumbing aisle slightly scares me….but since I’m not actually running pressurized water through it, and it saved me another five dollars, I decided to follow his advice.)

Paint color matching for a costume / Painting the Bracers

Mysterio Bracer and the glove

I drove to Home Depot hoping to find some spray paint to somewhat match the color of my gloves. As it turns out, even with an entire wall of spray paint, the only color selections with a “green” hue are limited to neon green, emerald green (which I bought, as it was closest to what I want, and may be useful in the future) and a leaf green. None of them were quite right, but I also made a discovery about the house paint counter.

Home Depot will sell you “sample” pre-mixed paints in 7.5 oz bottles to “test” a color for $3! Continue reading

Motorola Backflip (MB300) Review

Motorola Backflip (folded open, ready to use keyboard)
I have been using a Motorola BACKFLIP as my primary phone on AT&T for the last month. It is my first experience with the Android OS and smart-phones in general (my previous phone was a Motorola Razor V3xx “feature” phone), as well as my first full QWERTY keyboard on a phone. Overall it has been a positive experience. For the rest of my review, keep reading…

Jay’s list of the Best Android apps

I’ve had my Motorola Backflip for a month and have settled on a set of applications to keep on my phone. All of these applications work with Android version 1.5. My Backflip has a Camera / GPS / Compass and Accelerometers. Where an application makes use any of these hardware components I’ve mentioned it in the description. If you think I’m missing a great one, let me know!

How to sew (costume) gloves (My Mysterio Glove)

Glove sewn out of green cloth for a mysterio costume Mysterio glove and bracers
The pictures above show my right-hand Mysterio costume glove, on it’s own and with the bracer.

A note: I do not recommend that you sew your own costume gloves. It’s a lot of work, and takes a lot of time, which you can probably better spend on other aspects of your costume. However, if you have decided that your gloves NEED to be made out of specific fabric to match other aspects of your costume (such as Mystero’s boots), here is how to do it. Continue reading

Mysterio sphere, cape & bracers

Jay wearing the cape, sphere, and bracers
Here is a picture of the sphere, cape, and bracers put together. Obviously, I need to work on the green jumpsuit, gloves, and boots.
After a bit more work on the sphere, I am now able to see out of it relatively well. I used a standard green & yellow dish scrubbing sponge to buff/scratch away some of the reflective coating from the inside directly in front of my face when wearing it. I don’t have a lot of peripheral vision, and the view is slightly dimmed, but it’s much better than before. If you look very closely from the outside you can see that the “viewport” portion of the glass sphere is slightly less reflective than other areas, but because it’s dark inside the sphere I get the same effect as a one-way mirror. I have covered all of the rest of the interior of the sphere with packing tape as a poor-mans tempered glass substitute, but I will still be very careful walking or navigating steps while wearing the costume.

Sony PRS-300 Review

A Sony pocket reader (PRS-300) on top of a (slightly larger) paperback book.
I recently purchased a silver Sony digital reader (Pocket Edition , PRS-300) e-book reader. Electronic Ink e-book readers have been on the market for a while, but downward price pressure from tablets such as the iPad are making them much more affordable.

I typically read paperback books for around 80 minutes a day on my round trip train commute, and I have spent two days reading off of the Sony e-reader. These are my early experiences. Continue reading

Sculpy Mysterio Hooks

Two mysterio bracers, one with filleting using sculpy

Today I sculpted some fillets onto my mysterio bracers using Sculpy (An oven baked modeling clay). This gives the “hooks” a more three dimensional appearance, a bit more strength, and smooths out the connections between the hooks and the bracer itself. I only used 35g of Sculpy per bracer, so the hooks are not extremely wide, but I’m glad I added them, even if it will end up taking me 5 extra hours of work.

In the picture, the bracer on the left has the Sculpy, and the one on the right is pre-Sculpy. Continue reading

Android Phones on AT&T

If you are looking for a 3G phone running Android on AT&T, the pickings are slim. (Mostly because AT&T’s 3G bands are not compatible with many other carriers, and most Android GSM phones work with T-Mobile’s 3G bands. If you are willing to drop down to quad-band EDGE data most GSM Android phones will “work” with AT&T, they just suffer from slow networking.) Continue reading
