Canon eTTL Protocol

The Nikonos analog TTL protocol is relatively simple and has been reverse engineered by a number of scuba strobe manufacturers. The X contact is used to start the strobe dump and the Q contact is used to stop it. That's about it.


Canon Hot Shoe

My problem: trying to control scuba strobes from my new Canon G16.

I have ruled out optical control because my YS110 strobes work poorly in optical mode AND the G16 cuts out after about 20 onboard flashes in continuous burst mode. So now I am focused on wired sync control of my smart analog strobes via the camera hot shoe.

Scuba Camera Strobe Woes

Time for a brand new topic: Scuba diving, Cameras and Strobes. My problem is how to happily control my scuba camera strobes.

Drupal List Fields allowed_values_function == Custom Display Values

We had a simple problem and Drupal provided a simple (but very obscure and hard to find) solution. So I thought I would blog about it.

MyPhoneExplorer - Part 2

After a short burn in period involving multiple 2 way syncs with both my desktop and my laptop, I was ready to wean myself from Gmail.

MyPhoneExplorer - Part 1

Bottom line: It works as advertised!

At first glance the name MyPhoneExplorer was a little misleading as it seemed like a solution to look at the file system on your phone. Not so. It is a true 2 way synchronization tool. It is capable of talking over WIFI, Bluetooth or USB and can sync Contacts, Call Log, Calendar, Notes, Messages (email) and Files. I only tested Contacts and Calendar.

My phone is my Personal Cloud

I had a simple problem:

  • Synchronize my Contacts and Events across an Android phone, a laptop and a desktop.

I already had this feature by the use of Gmail. But I was dumping Gmail.

My Gmail account had provided a centralized synchronization point. It was obvious that any viable solution would also rely upon a single synchronization point.

Personal Clouds

As part of my quest to wean myself from Gmail, I discovered that I needed a Personal Cloud. The Great Marketing Machine has invented yet another buzzword.

Additional research indicated that unlike IMAP, there did not seem to be simple WebDAV / "personal cloud" solutions. Everything I found was very large and complex with many fragile dependencies that involved several kitchen sinks.

Email is not an Address Book (or a Calendar)

Weaning myself from Gmail was not as simple or obvious as I first thought it should be.

Someone has your password!

Gmail hates me...

Well not me personally. I am fairly sure Google is not aware of me as an individual. I am not that important. But "in order to serve me better" it has  always made my travel life a misery. And now it has raised the bar to a personal hatred level. I have had enough...nothing personal, but I want a Gmail divorce!
