Loading mobi books into Touchpad's Kindle App

I have purchased many ebooks and created others manually in the .mobi format. This is very easy to load onto my Kindle device to read. Unfortunately, the current Kindle app on the Touchpad does not allow loading ebooks other than downloading from Amazon. This is unfortunate and makes the Touchpad a poor replacement for my Kindle.

Touchpad WiFi - Hidden Passcode Hell

August 2, 2011

I have just spent the last 30 minutes trying to get our complex 64 character WPA key into my HP Touchpad so I can start the setup procedure. The password field for the WiFi key is frustrating. The last character is only shown for a second or two, then it too fades into the dots of obscurity.

HP Touchpad

July 1st is the day that many WebOS users have been waiting for. The day that HP releases their first WebOS tablet, the Touchpad. I preordered through Amazon and was delivered my own spanking new HP Touchpad tablet this evening. Overall it is an amazing piece of technology. Slicker than any Android tablets that I have tried, but not quite as polished as an iPad. However, for me the usability is far above an iPad, whose “multitasking” is a joke compared to the Touchpad.

Enhancing the AVR ISP II

May 23, 2011

The AVR ISP II is a device to program an AVR microcontroller using a 6 pin header in a circuit. It does not contain any capability to power the circuit being programmed. This could be very handy. Dave Jones at the EEVBlog has a video about adding power to the ISP cable, using an LM317 to provide both 5V and 3.

WebOS From Homebrew to Catalog: tips learned in the process

March 1, 2011

I’ve been a developer, on many different platforms, for just under two decades. Like many code monkeys, I enjoy learning new architectures. I’m not exactly sure why, but programming for WebOS has me more excited than I’ve been since working with GCC on the Palm Personal. The idea of building apps with web technologies on a portable device sounded interesting. I knew that certain things would be easy and others hard.

TouchStone Theories Confirmed

February 22, 2011

Precentral.net read through the initial TouchStone theory post I put up and asked HP about my theories. As they posted in this article on the site, HP confirmed the identification to work as I assumed. The new TouchStones will use the 3.1 MHz frequency to pass a unique key to the new WebOS phones, which will enable them to know where it is docked. You will obviously have to tell the phone where each dock is located the first time you use it.

WebOS Touchstone - Now and Future

in tech    5 min. read

February 15, 2011

When the Palm Pre was released, Palm also sold a unique inductive charger called the Touchstone. Inductive charging isn’t new, by any means. Electric toothbrushes and many other devices have used them in the past. This was a first for cell phones, I believe. When I purchased my Pre and eventually many Touchstones, I didn’t have a good oscilloscope to play around with the signals.

Amateur Extra Class - No More Tests

I studied for a month or so and re-learned quite a bit of electronics for AC circuits. Resistance, Reactance, Polar Impedance. I took the test on the morning of February 5th and missed 1 out of 50. So now I am an Extra Class Licensed Ham Radio operator. No more tests to take. This is as high as it gets. I am still working on what type of antenna to put up.

Bencoding (encoding of a .torrent file)

in tech    7 min. read

December 21, 2010

The Bencode format is an interesting design. It is byte based, which makes it safe from big-endian and little-endian translations. Somewhere when reading about how torrents worked, I got looking at their file format. As far as I know, the Bencode format isn’t used on anything but torrent files. The format is pretty simple, with only 4 different data structures: Byte String, Integer, List, and Dictionary. Bencode Basics Byte String This is formatted as [integer length]:[byte string].

I'm such a HAM...

December 18, 2010

Years ago, Dad and I attended meetings for Amateur Radio at the local Red Cross building in Jeffersonville. We both worked through passing the 5 words per minute Morse Code and test to get our Novice license and then studied and passed the test for Technician Class. I was licensed in 1990 and expired in 2000. Just when I was starting work in the “Real World”, outside of college. I didn’t bother renewing.
