"I've missed you so much, baby. Have a great flight. See you soon, my dear..."
I ran across this so-so quality, but funny shot which I was just about to trash. I came up with this interesting idea and saved it in the very last moment. The shot is 100% real and nothing was changed but obviously the phone, which was photoshopped in. The eagle kept moving its claws all over the place while I was watching it. Hope you'll enjoy it.
Have a fun week everyone!
Timings are ready now. The table show the values between 1/256 power and full power. Using the Puls LA timings for driving the TTL mode gives the right output power.
On the LA you see the X and Q signals. X signal is here 15 usec width and Q signal 25 usec. The delay value between the X and the Q signal define the correct output power.
The X signal need to be more then 10 usec or the flash d'nt works. Large puls is not critical.
I've tested the recovery time, this is the time to start a second flash cycle. This critical time is for this SB-80-DX near 40 msec. This means that only near 50 msec a second flashpuls can be generated. For my waterfigures I need pulses between 1 and 5 msec. So I need 2 different flashes if I will use this option.
For wireless control you have to setup first the powerlevel remote via a protocol.
There after you can give via the RFM12B module a command to fire the flashes. In case of SC-27 Nikon cable (remote TTL cable) you only need to give the X and Q puls at the right time.
Very easy, and lowcost central remote control of all your flashes!

I build a prototype Master with the RFM12B wireless module. The master can also drive local 3 flashes in TTL mode and have an extra LCD display of 2x16 char. The master transmit also the signals to the slave ( slave have 4 flash outputs in TTL mode). Master and slave flash signals are so calculated that all the flash powers are centrered even if the powers are different. This is very important for very highspeed systems. If flashes are not centrered blur into the highspeed capture may happen.

Most of the parts are now soldered on a board to put into a nice box. Within a few days the hole unit will be ready. Picture will be follow.
Update 2009 Sep 21:
new timings are added for the SB-29-S ringflash and some others are updated. The new results stay on:

The Findlay Village Mall opened in 1962 with a JCPenney and Britt's discount store as anchors. Sears built a store in 1963. In the late 1980s the mall underwent a major renovation that involved adding a new wing with an Elder-Beerman store and reusing the old Britt's store as a Kmart. In 2003 the mall lost Kmart (now Best Buy, Dunham's, and T.J.Maxx)and Sears closed in March 2014. Currently many sections of the mall have a notable amount of vacancies.

It’s a half-wave rectifier, used in transmitter power supplies, and consists of just two internal elements; a directly heated cathode and a cylindrical anode. The cathode emits electrons which are pulled to the anode and so the valve only supports a unidirectional flow of electricity. The key specification parameters are:
Filament voltage: 9.0 volts nominal / 9.5 volts max. D.C.
Filament current: 5.75 amps
Anode voltage: up to 8000 volts
Anode dissipation: 200 watts
Dimensions: depth/width 110 mm, height 185 mm
When the filament was powered it would have lit up like a lamp, hence these valves were known as ‘bright emitters’.
The valve was originally manufactured by GEC’s Osram lamp works for Marconi’s Wireless Telegraphy Co. Ltd. There was also an Edison Swan Electric Co. (Ediswan) version. Production started in March 1919.
The initial production items were used in early shipborne transmitters, in the Croydon Aerodrome transmitter (GED) and in the Marconi company’s experimental station (MZX) located at Chelmsford. The latter caused a sensation in 1920 when Dame Nellie Melba gave a performance of songs broadcast at high power across Britain and into the near Continent.
The boffins at Marconi also used the M.R.1. for the power supply design of the 2MT broadcasting station at Writtle, close to Chelmsford. 2MT was Britain’s first station to broadcast speech and music on a regular basis between February 1922 and January 1923.
This example, serial number of 8565, has a late-1920s Marconi logo. Unfortunately it has lost one of its filament connection wires.

A BT Voyager 2091 - this services our entire house, including all the stuff in Tim's office/studio on the top floor. (Update (Dec 2007): this connection used to be made via a wireless Ethernet bridge, but it is now connected via two HomePlug 85Mbps adapters (i.e. Ethernet over the power lines in the house).)
The router carries the unofficial hostname of 'kamidake' (following the naming convention on the home LAN of characters from 'Tenchi Muyo' - it's a long story), but the name is not really used.
