Die XR7 ist eine XR-S ohne Solarzellen. Auch hier ist die bemerkenswerte Robustheit hervorzuheben, die alle in meinem Besitz befindlichen Ricoh-SLRs auszeichnet.
Kurz ein paar hervorhebenswerte technische Daten:
Der vertikal ablaufende, elektronisch gesteuerte Schlitzverschluss geht sowohl im manuellen als auch im automatischen Modus von 16 Sek. bis 1/1000 Sek.
Auf einer Belichtungszeiten -Skala im Sucher wird die gewählte Zeit mit einem digitalen Zeiger markiert. Eine Abblendtaste ist ebenso vorhanden wie ein Messwertspeicher. Mehrfachbelichtungsmöglichkeit, Belichtungskorrektur und Selbstauslöser sind weitere Ausstattungsmerkmale. Im großen und ganzen eben alles was man braucht.
100 ohm, 1/4 W resistor.
As seen on Alpha Clock Five!
From an article about power dissipation, on our blog here.
One of the circuit boards that appears in the "transistors" shots. Labeled with the Hewlett-Packard logo (not shown here).
Here is the main power plug, power switch and some other components in the power path.
The two little grey squares (FB20 and FB21) are Ferrite Beads - essentially some small chokes to try and filter out harmonics in the voltage (the input is AC not DC).
Between the plug and the two ferrite beads are two Capacitors C150 and C155. The internal pin of the power plug is tied to C150, which leads directly to C155.
I cannot see any way to see markings on C150 or C155 to determine the ratings of the two capacitors.
A had to take a broken DVD player to pieces in order to retrieve an X Files DVD which was trapped inside. So, I thought I'd take a few photos.

What light through yon window breaks? Hey, it's the sun! Had some great natural light in the office today. Took five minutes to sunbathe a few older beauties.

I can't believe that I am already on week 18. It seemed like just yesterday that I started.. And I could not have done it without all of your support!! These past few months have gone by so fast. :)

Please visit my collection of Motor Vehicles on Flickr where you will find over 10,000 car and truck photos organized in albums by model year, manufacturer, vehicle type, and more. This project, which began in 2008, continues to expand with new material added daily.

I just finished this yesterday. Based on an original design that I built in college, this is an LED lightshow that plugs into any audio source. (I have it on top of our home entertainment system, so it shows whatever we're listening to or watching.)
The display is divided vertically into left and right channels. It displays the top half of the waveform of each channel with their zero levels in the center. The two knobs control the amplitude and the sweep speed.
When set to the right speed, a strong bass note will show up as a floating red bubble. A note an octave up will be two bubbles. Notes inbetween will be a series of bubbles floating up or down the display. Of course, all the other frequencies are in there, too, so you get a much more complicated display, but the bass tends to be the most prominent. Dynamics from drums, etc. cause the width to pulse. It all ends up being quite hypnotic.
The box... well, it's just a black box I built with a plexiglass front. Suggestions for a sexier box are welcome!
Here's the link to see the box in action:

Update October 13:
Here's the circuit diagram! Please let me know if you build one!
Dacora Super Dignette E-B (1962)
Optische Werke Steinheil München - Cassar 1:2.8/45mm lens
Prontor-LK shutter 1/15-1/500 and B
Coupled rangefinder
The selenium exposure meter is displayed by a needle in the viewfinder, so one can get the right exposure without taking the eye of the viewfinder.
The needle is replicated on the top plate.

History of DIY audio
Audio DIY came to prominence in the 50s to 60s, as audio reproduction was relatively new and the technology "complex," audio reproduction equipment, and in particular high performance equipment, was not offered at the retail level. Kits and designs were available for consumers to build their own equipment. Famous vacuum tube kits from Dynaco, Heathkit, and McIntosh, as well as solid state (transistor) kits from Hafler allowed for consumers to build their own hi fidelity systems. Books and magazines were published which explained new concepts regarding the design and operation of vacuum tube and (later) transistor circuits.
While audio equipment has become easily accessible in the current day and age, there still exists an interest in building one's own equipment, including amplifiers, speakers, preamplifiers, and even CD players and turntables. Today, a network of companies, parts vendors, and on-line communities exist to foster this interest. DIY is especially active in loudspeaker and in tube amplification. Both are relatively simple to design and fabricate without access to sophisticated industrial equipment. Both enable the builder to pick and choose between various available parts, on matters of price as well as quality, allow for extensive experimentation, and offer the chance to use exotic or highly labor-intensive solutions, which would be expensive for a manufacturer to implement, but only require personal labor by the DIYer, which is a source of satisfaction to them.

Just finished my new stereo shelf, instead of the crappy computer speakers I run this setup now. Speakers slightly tilted downwards. Sounds great!
More spec just for the record:
Audio source: Yamaha CD-NT670 D
Amplifier: Yamaha A-U670
Speakers: Monitor Audio Bronze 1
Canon 450D, Canon 500 (Film), Canon 35-80, Canon 50 Macro 2.5, Tamron 17-50 2.8, Samyang 8mm, Yashica 50 1.9, Yashica 135 2.8, Sigma 70-200 2.8, TC 2x TelePlus.
To find out the true frequency I need another transmitter or reference VFO that can transmit in this range. The way the morse receiver works the frequency displayed is not the actual frequency it's listening to, though the difference isn't large.
My new, second-hand 50D upgrade from my first DSLR - the EOS 400D.
Now that I've a new DSLR, I've decided to try on the firmware hack to my 400D - 400plus It's quite a nice hack... with spot metering, ISO up to 3000, actuations info and so much more... And I just realised that my 400D has just under 10,000 actuations only! The second-hand 50D I've got has 34,000 already. Let's hope the shutter on the 50D lasts for a very long time...
Because next Thursday is my 29th birthday, I decided to buy myself a present. :-)
God... I hope I'm making the lot of you jealous now. :-P
