Air Festival

The local Air Force Technical School had an open day on the weekend with flight and aircraft displays.

A lot of student projects were on display too. Some had made fire fighting robotic models, others were explaining hydraulic or other aircraft systems.

Space Camper

My daughter went to Space Camp Turkey a few weeks ago for a three day school trip.

"It was pretty fun - very fun indeed".

She learnt a lot of stuff about space including the Mercury astronauts, the Gemini program, the Apollo missions, space shuttles and mission control.

She went on some simulators.

She also built and flew a model rocket and in one evening session she saw Jupiter and four moons through the telescope.

Easter eggs

Easter eggs are hidden gems inside movies, dvds, software and websites.

Have you ever made any?

I created a couple of Easter eggs three years ago on the Factory Reset wiki. This wiki has user created instructions for resetting a number of devices back to their factory settings and is a good resource if you need to get your device back.

Laptop screen repaired

My ancient Dell Inspiron developed problems with the screen about 18 months ago.  The LCD panel was OK, but the backlight was not working. In the meantime, I have used an external monitor with it.

Inspired by a recent episode of the Ben Heck Show where Ben replaced the inefficient CFL tube with LEDs, I had another look at repairing the screen. Opening it up, I discovered that one of the tube's connections was broken and so after soldering it back together, the screen is working again.
The CFL tube removed from the screen

The end of the tube where the bad connection had shorted out

Starting to put it back together
You can see the various layers of magnifiers and diffusers for the backlight 

It works again!

Only glitch is some dust in between the diffuser and magnifier layers
