That package "U105" is really odd. I've never seen anything like that before, and have no idea what it is. U104 is the same type of thing. Given the size of the traces and caps near them, I assume they're power-related, and that's why they have such a huge package. Maybe some sort of regulator?
Not anything dangerous...Nor was it shot at 12:05 AM. It's just I've been monkeying with this particular (almost) antique alarm clock for the past few days, and found out its original alarm off button doesn't work. So, like any good hacker does, every time they want that alarm to shut off (besides snooze) they open it up and short the appropriate wires. Turns out, shorting just anything often works to reset it, and shorting the upper red wire to pin 4 on the chip shuts the alarm off for the day.
Former RCA Technical Institute at Cherry Hill Industrial Park in Cherry Hill NJ, opened in the early 1960s. There were also RCA Institutes in New York City and Los Angeles, and they had home training courses. In the mid 1970s this became Sylvania Technical School. It was later Lyons Institute, I took a course here in Electronics and Digital Technology in 1982-83. It is now JDR Shoe Warehouse store.
The clock is assembled in a semi-enclosure made from old cassette tape cases. (Thanks to Denis for this idea.) Yes, it's a bit messy.

For those that know me, know my GSR was my first car and I still have it. Then I went through two EF9s, which I sold, the CRX which I have on the side, and my current daily Integra. After going though those cars, nothing felt like my Integra and being how I built it for the track, its not practical to daily anymore. This layout of the Integra feels like home to me. Same year as my DC2 just no VTEC. I love it. I guess its the simple things that make me happy.
Have a nice day!

Here are the buttons. I'd actually prefer a softer cap on those switches, but it's good to see that these aren't just cheap tactile switches, but higher quality switches with more throw. These should last a long time and take a lot of abuse.

An interesting corner of the main PCB, with RF shielding removed.
Taken with a reversed 50mm prime lens, taped securely to a filter adapter attached to my Canon S70.
My phone died recently. I think the charging circuit quit working, because it would recognize being plugged into power, but the battery never charged. It has since been replaced.
I illuminated this motherboard by shooting a green-geled flash behind it.

I've now got it so that when the time changes, the clock display fades from the old time to the new time over the course of about 1/3 of a second. It's a tough effect to photograph - here you can see the seconds* ticking over from 59 to 00; in both cases the 59 is very dim and the incoming 00 much brighter. I shot it from two different angles to show the face-on view and obliquely so you could see how the numbers are stacked in the tube.
Trust me - in person, this effect looks really, really cool and now I know why some nixie-clock-building geeks make such a big deal out of it.
A big part of my design decision to make this nixie clock microcontroller-based was that it would let me do nifty display trickery like this easily. Nixie clocks don't need to use computer-type guts; a very popular circuitry design for them uses only discrete logic chips ("popcorn"). Popcorn is a lot like circuitry legos - you can get chips that do all sorts of little jobs like counting from 0 to 9, or for converting a binary number to a decimal one. There are 4 of the latter on this clock's driver board.
The popcorn version has the advantages that a) the builder doesn't need to know any programming or own any equipment for burning microcontrollers and b) it might last longer; microcontrollers' flash memory may "forget" their programming after a mere decade or so, while discrete logic is hardwired to do what it does. However, I'm not sure if the nixies themselves will outlive the microcontrollers' memory retention.
Microcontroller-based clocks, apart from fancy display stuff, can also be easily interfaced with very accurate, battery-backed real time clock chips (like I did) or even to GPS or radio circuitry that automatically synchronizes them to the official atom-clock time. Nifty!
*But wait! You say. Seconds are showing on a four-tube clock? Why yes. I borrowed a trick from the ancient LED-wristwatch days and have a button you can press to show the seconds on the rightmost (minute) tubes while the leftmost (hour) tubes are blank. I hadn't really planned on this, but it's just too much fun to watch the seconds tick by. Hypnotic, even.

2014 Buick LaCrosse, Adaptive Cruise Control alert displayed in the 8-inch instrument panel (IP). This image also features next-generation IntelliLink infotainment system as well as the Light Neutral Soleil Keisel leather seating and Cocoa accents interior with Kyoto Maple wood-style decor.
Nice thick steel panel for mounting the encoders. This makes it easier to remove the top panel without scratching things up, and also lets the whole thing take more abuse while not requiring the top panel be made of thicker material. Plus, it just looks nicer not to have the nuts showing through the top panel.

The first camera with a built-in electronic flash:
The batteries and electronics are housed in a bayonet fitting, on the bottom of the camera, pistol grip
A switch in it controls the charge of the capacitor: continuously charged or just at the pressure of it
There's a flash ready indicator in the viewfinder and also on the top plate
GN 9 @ 100 ISO, recycle time 8 - 15 seconds
For automatic operation of the flash, 25 - 400 ISO, the lightning symbol, in the aperture ring must be selected, the aperture will relate to the focus distance
24 x 36 mm exposures on 35 mm film
Filter size 32 mm push-on
This camera was a gift of my cousin António Abílio Dantas Gomes
