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

IBM Think pad X31 Radeon M6 – Suspend Screen Fix

My Thinkpad X31 laptop with a Radeon M6 graphics chip had a problem with ACPI Suspend/Resume. About every five resumes, the graphics card would get messed up, making the screen unusable.
The computer would suspend/resume fine otherwise, but I’d be forced to reboot just to get X working again. (Just shutting down X and re-starting it wasn’t enough.)

The easy solution is to pass a “nomodeset” option to the kernal upon boot, but to do this on different versions of Ubuntu you need to do modify files in different places.

9.04: Edit the /boot/grub/menu.lst file, and look for the defoptions= line. Add nomodeset to the end. Run sudo update-grub afterwards to save your changes.

9.10: Edit the /etc/grub.d/10_linux file to add a line such as:
GRUB_CMDLINE_EXTRA = "$GRUB_CMDLINE_EXTRA nomodeset"
or just add “nomodeset” to the end of a previous GRUB_CMDLINE_EXTRA entry. After this, run sudo update-grub.

10.04: Edit the /etc/defaults/grub file and change GRUB_CMDLINE_LINUX="" to
GRUB_CMDLINE_LINUX="nomodeset"
(You may have to run sudo update-grub again, or it may be taken care of for you)

Commentary: I find it funny that in each of the last three version’s of UBUNTU the name and location of the grub configuration file has changed…

Mysterio Cape


Today I started on the actual costume part of my costume (as opposed to the props) and found 3 yards of remnant fabric ( $1 per yard!) that is approximately the correct color for my mysterio cape. Because the costume needs something that is closer to a cape than a full cloak, I made a “half-circle” cloak, which typically falls over the shoulders but doesn’t completely close in the front. [A full circle cloak is MUCH more massive and would hide most of your body.] The trick to cutting an even half circle is to fold your fabric in half, have somebody hold a piece of string at the corner, and trace out a quarter circle (with a washable fabric marker if you have one). When you cut out the quarter circle and open your fabric back up, both sides of your half-circle match. Then do the same folding trick when you cut out a neck hole. Remember, you can always cut more, but adding fabric is hard. If you get lucky and find a knit fabric that doesn’t fray, you may not even have to hem the edges.

notify-osd render problem with Radeon M6 (Ubuntu 9.10)

After upgrading my IBM X31 Thinkpad to Ubuntu 9.10, I noticed that libnotify (notify-osd) pop-ups were having a visual artifact when rendered that made the text unreadable. After a half hour of searching the net, I determined that this was because my M6 chipset doesn’t support Render Acceleration correctly, and the default xorg.conf file from Ubuntu does not disable that setting for my graphics driver (Radeon M6).

The solution is to add the option:
Option “RenderAccel” “false”
to the “Device” section of your /etc/X11/xorg.conf file.

Hidden Roomba Diagnostic checks – Stuck Bumper Sensor

Roomba with stuck bumper sensor
The above video shows a roomba with a stuck front bumper sensor. As you can see, the robot keeps backing up and trying to turn away from
the phantom obstacle it thinks is in front of it. This particular sensor was triggering because lint had gotten into the optical beam path and was blocking light to the photodiode detector even when the bumper was not being hit. I was able to repair it by removing the bumper cover (unscrewing 4 screws) and vacuuming out the hole where the plastic pole from the bumper goes between the IR diode and photo-transistor.
