My PCB order from Golden Pheonix arrived, a day less than two weeks after ordering them. Not bad turnaround!
The PCBs themselves are really nice and I have loads (ordered a panel though I'll only need one or two of each), though I'm yet to actually solder them up. I plan to use some solder paste I just got and reflow them under the grill, which I hope will work.
The only problem I've identified is that one of the PCBs is physically broken (a small bit snapped off when being cut presumably) which breaks two traces, but they'll be easy to fix with a small wire if needed.
They are for my current project - see if you can guess what it is!
The brains of the operation! I love the mechanical aspect of camera building, but adding electronics to the mess is also a thrill. Here I have my previously-featured SLS shutter controller, which is an Adafruit Trinked microcontroller (running on the Arduino IDE), hooked up to a lithium-polymer batter for power, mini solenoid for shutter actuation, and some bits and bobs for user interface. The little white square near the left of the camera is a 10-position rotary DIP switch, which is used to control the shutter speeds. Unlike the potentiometer I was using before, it has obvious detents to show where each speed lies - it feels really nice. I used a binary weighted digital-to-analog circuit to interface with a single pin on the Trinket - really simple stuff, but I'm proud as a mechanical engineer for figuring out that little bit of EE nonsense!

This how I normally setup my camera when I'm taking close up shots of people. For the purpose of showing you exactly how my camera was setup, I had to mount it on my Manfrotto 055PROXB tripod using a Manfrotto 026 Swivel Adapter in lieu of an actual tripod head mount (I haven't picked up one yet because the one I want costs around $180). I used the Nikon AF-S DX Nikkor 35mm f/1.8G lens to take the shot. My flash is mounted on a Newton Bracket which allows me to rotate my camera vertically without having to change the position of the flash. Attached to the flash hot shoe of the camera is a Zeikos ZE-OCSCN Off Camera Shoe Cord for Nikon Flash. The Nikon flash cord costs $68 on Amazon while the Zeikos that I use only costs $14. So if you need a dependable flash cord, pick up the Zeikos and save some money. The reason I use the flash cord is because of the inconsistency of using Nikon CLS to trigger my SB-700 flash when in this configuration. At first I was using the SB-700 with the Newtwon Bracket and Nikon CLS to trigger it but I experienced misfires. The SB-700 is in TTL mode with the diffuser dome on. I have a Rouge Flashbender wrapped around the top of the SB-700 using it as a big bounce surface which works very well. I got the idea to use the Flashbender in this manner from watching a Kelby Training video about using a flash to light a group of people. As you can see, this setup works like a charm, it produce a very nice even light and lights up the shot just right without causing any real hot spots. For the Day 098/365 shot, my camera was in Manual mode, IS0 100, Aperture f/1.8, Shutter 1/125sec. I shot wide open at f/1.8 so that I could blow the background out with bokeh.

This camera doesn't get used much. I really like it, I just need to get in the habit of bringing it along with me.

A cased version of the Vibrati Punk Console:
Optimized for studio and performance with line-out and pulse control.
Olympus OM-D E-M5 with Leica 25/1.4 and Fuji X-Pro1 with Fujinon 60/2.4 portrayed by Nikon D800 with Nikon AF-S 50/1.8G
The main board from an Ensoniq Fizmo synth.
The voltage regulator (far left edge of board and nestled between the two sides of the heatsink and labelled LM2940T) is one of the types that goes bad and sends too much power to the rest of the board. It's rated for 1A but when it goes out it draw more than that.
I'm replacing it with a brand new MC7805CT which is a LDO (low-dropout option) 5V rated for 1.5A, and going to use a new external power adapter (wall wart) which is 1.3A.
I recently managed to find a brand new Contax G2 & 45mm f2, so of course I had to buy it some companion lenses
Seen Here: The PCB out of the bag! (Torch see-through vision!)
So, today my PCB for the LED matrix arrived from BatchPCB! For what I paid, the PCB arrived fairly quickly - I ordered it on the 15/02 I believe, and it arrived 11/03 -- 26 days, which is pretty good (they state 19 business days).
The quality is very, very impressive - far better than anything I could pull off at home. The silkscreen and soldermask makes it look really nice, too.
Soldering it was a joy, although there was a LOT to solder and it's all surface mounted.
I had a few problems at first; it wasn't lighting the matrix at all properly but I soon realised with my new design (transistors on the cathodes) I have to write the transistors HIGH to get a LOW on the cathode, so a quick line of code changed to get that working.
Then for some reason the top half of every letter was flipped. It turns out this was my fault: I messed up when making the package for the LED matrix in Eagle, swapping the matrix's 5th cathode for my system's 8th, 6th for 7th, 7th for 6th and 8th for 5th. This was fairly easy to fix in code, however.
Finally USB isn't working to program or communicate, but I can configure the FT232RL chip (after all, it's sending the clock pulse that's driving my ATmega168). I think I have an idea of what's causing this, but I'm not sure yet.
The Pax are 35mm viewfinder and rangefinder cameras made by Yamato Kōki Kōgyō in the 1950s and 1960s.
My latest lens arrived today, a Panasonic Leica DG Summilux 25mm f/1.4 Asph. Micro Four Thirds lens for my Olympus OM-D E-M10.
I had read up very carefully about all the fast standard lenses for the Micro Four Thirds system so I knew that, by M4/3 standards this is a big lens, but that didn't really prepare me for just how big this lens is. And the huge lens hood Panasonic supply with this lens (which I don't show in any of these pictures) only accentuates the size of the lens itself!
This lens really does dominate the E-M10. Having said that I still think it is a very handsome combination, which isn't always something you can say about putting one manufacturer's lens on another manufacturers body.
Here you can see this lens next to Fujifilm's 35mm f/1.4 X mount lens. They are about the same size and the Panasonic Leica lens is actually very slightly heavier (not what you would expect of a lens designed to cover a smaller image circle).
I'm off to Berlin next week, which will be an excellent opportunity to give this lens a proper work out!
Full marks to Panasonic for supply a lens as part of the standard package for this lens, but a big minus mark for designing one of the worst lens hood ever in the history of lens hood. Not only is it huge, but it doesn't fit backwards over the lens for storage while travelling and there is no lens cap that fits over the lens hood either.
Please, Panasonic, checkout the lens hoods Fujifilm supply with their lenses. They are compact, efficient, effective and they also supply an extra lens cap that fits over the lens hood when it is mounted on the lens making it very convenient to just leave the lens hood on 100% of the time.
