Prisoner of War Radio
This is an example of a radio that would have been built and used by prisoners of war during the Second World War. These radios allowed the prisoners to listen to Allied news reports and follow the progress of the War. They were among the most important items to maintain their morale in the camps.

Adding to the book list for 2015. Lots learned and so much more to learn!
I love these Logitech Marble Mouse trackballs, I have one for every computer. After a few years they slow down physically. Cleaning the dust off does not help enough, something different needed to be applied. I’ve been researching lubricants and oils, doing some tests with households; but I think I’ve found the perfect fluid. Ian Gomes of Union Sound Company made a recommendation a few years back for Penny and Giles faders. A quick amazon search lead me to Lucas Silicone Shock fluid. I must report that it is the perfect product for this application. If you need a drop, I’ll send you a q-tip of it in the mail.
Summer sale!

Someone picked my brain the other day looking for a technique to compress language files.
After walking away to think about it… my method was to re-order the ASCII code to the letters by their frequency and the most common words by their frequency.
Where lowercase e is stored as an ASCII value using 1 byte
ASCII e = 0x61 = 0b1100001 = 7 bits
vs
APK e = 0x1 = 1 bit
… this method stores an E in 1 bit. This is similar to the Huffman Code with the addition of whole words being included in the code.
For example:
“because” is the 94th most used word in the english language and in this method is stored in 7 bits.
I don’t know if this has been done before… but I would imagine it could compress Language files substantially.
I have thought about a third addition of using the most used 2 or three letter combinations commonly used.

A colleague posed a very interesting question:
“I am looking for any music/music math wizard help me figure this out. If I am moving the pitch of a song up by 50 cents (a quarter step?) What frequency is A instead of 440?”
Sounded like the kind of math challenge I like:
To test and confirm that it’s calculating properly, this is up 100 cents making G# 440
This is down 100 cents making A# 440
