One of my newly acquired power converter boards didn't want to work. A closer look revealed the reason - Mr postman has been playing football with my package, and the inductor is rather beaten up.
Close inspection showed another board had similar, but less serious damage, and was still working. This one however is dead.
Oh well, could be worse. Only a 25p component, I'll change it over.
Only tricky bit is it is only 2.5mm wide - see, it is a macro! Best I lay off the caffeine before I do this one!
The board is an AA power board from Jeelabs.
This clever little board mounts a single AA or AAA battery (rechargeable if you like) and converts the 1.2v or 1.5v into 3.3v to power the JeeNode boards I use for my flash triggers (amongst other things). I've got a few code changes to make which will improve the power consumption of my remote flash triggers, but even now, thanks to this board, a single 2400mAh NiMH rechargeable battery can run a remote unit for 20 hours solid. Far longer than both I or my camera battery can last! Plus as this DC power converter board will produce 3.3v from input voltage as low as 0.8v I can even run it on batteries that are "flat" as far as the flashes are concerned.
I guess I should have a look at mounted a solar panel and NiMH charging circuit in the box and then the remotes will recharge just by putting them on the window ledge!
The title? Well inductors are measured in Henry's after an American Scientist Joseph Henry who discovered electromagnetic induction at about the same time as Michael Faraday. Faraday had already given his name to capacitance, so Henry managed to avoid an argument on this unit!

Lighting via SB800 in TTL mode triggered by CLS. Flash is about 5m above the board slightly to the right pointing down at 45 degrees. The SB800 has a built in catch light bounce card, which I deployed, this acts a great reflector on a target this small and throws some light from the left hand side.

Robyn/ Call your girlfriend
I am so into Robyn at the moment and I listened to this song when I was taking these pictures- and it just seemed to match Lilith's attitude so well! ;)
I am very glad to have with me: Wild at heart Lilith (my first Lilith!) and the most amazing gown by em'lia couture. This is a very special gown to me because em'lia made it for the DCDC (which she won!)- I remember loving this gown from seeing it first at the contest, and reading the story about the design, and the fabric, on her blog.
I admired em'lias work in this contest and it really gave me a new idea of where the doll hobby "can be going". Not long after that, I did my first commission with her and the rest is history ;) And now I have a small piece of that story at home t put on my dolls and admire! ;)

Will absolutely, have to force me to use this AC Generator, but it's there in the event of an emergency.
Molly McMullen began her dance training at South Dayton School of Dance in Dayton, Ohio. She was a ten-year member of South Dayton Dance Theatre, where she danced frequently with Dayton Contemporary Dance Company members.
Molly has attended various summer intensive programs including Cincinnati Ballet, Ballet Chicago, DCDC, Parsons Dance, Paul Taylor and Hubbard Street Dance Chicago. She also danced for Pittsburgh’s Attack Theater in the 2011 Dirty Ball. She has performed in several RDA ballet festivals and in 2006 received the Jeraldyne Blunden Award, which allowed her to attend the national Craft of Choreography Conference at Utah Valley State College with a full scholarship. Ms. McMullen graduated from Point Park University magna cum laude in 2012 with a BFA in dance. She has had the great opportunities of performing works by Daniel Marshall, Jonathan Phelps, Doug Varone, George Balanchine, Darrell Grand Moultrie, Kiesha Lalama and Alan Hineline.
Talking about this technology is complicated, but a simple breakdown of common vocabulary will help even amateurs navigate the field. If you need help, find a reliable company: www.hvmtech.com.
1.5V comes in on the right and +3.3V goes out the left. Both black wires are attached to a common trace on the board.

Have it, so I installed this small AC Inverter, to provide 120vac in the event we need power for displays at carshows, earthday events, or emergency power when the grid is down.

Fits in the same space as a AA battery. I need to put some form of contact on each end plus a ground spring on the side for use in a mini Mag light.
The circuit draws 0.07 mA when idle so it should have a minimal effect on battery life.
With the LED connected it's drawing near 90 mA which should last 25+ hours with a high capacity NiMH.
