1960's competitors. Without lightmeter and with. Both sold now as I realised I could get the same results with TLRs 1/3rd the price.

Alternative to other CSC offerings, this capable camera made by the most evolving electronics company is a interesting offering now, when the NX300 is here. Large APS-C sensor with usable ISO 3200, easy handling, very solid build, many functions for both amateur and advanced photographers, full controls, WiFi connectivity, 8 fps, and very good lenses. The 18-55 is really nice, and firmware modifications made the auto focus faster and raw files smaller. Now when the production life of the NX210 comes to an end, some local resellers run crazy and the price is falling like a stone - I found this one for $250 with some benefits. For that money it´s a quite powerful and handy camera.

I want to try use "normal" prime lens on cropped camera, and I was lucky to got this little gem on ebay.

Selective colour of a 47,000 (4.7K) ohm 1/2 watt resistor.

The adapter is a little tighter than the P6 camera mount, so my Kalimar adapter won't quite go in. But frankly, compared to these Zeiss lenses, not being able to fit the Kalimars is not a huge sacrifice.

"Manufactured by Carl Zeiss Jena DDR, Flektogon MC 35mm f/2.4 was available in M42 universal screw, Exacta and B (as Practicar lens) mounts in both auto and electric versions. Manufactured up until reunification of Carl Zeiss Jena with Carl Zeiss of West Germany, the lens is more or less readily available on used markets, with good quality copies fetching about US$150 (as of August 2007).

 

The lens, which carries MC designation (standing for Multi-Coated), replaced its older and slightly slower single coated variant - Flektogon 35mm f/2.8. The optical design of the lens consists of 6 elements in 6 groups. The build quality of the lens is superb - barrel, focus and aperture rings are made of lightweight durable metal. The lens is pretty light and compact, weighing 250g (8.8oz) and measuring 51x61mm (2x2.4in), although the inner cam extends during focusing towards closup."

Raided the PC spares box again today, as it was raining heavily for most of the day.

 

This is my previous main motherboard, now redundant and, apparently, gathering dust despite being both bagged and boxed to protect it!

Netronics ASCii Keyboard with "FastVid" board in its original heavy gauge metal "Big Blue" case. Supplied as a self-assembly kit for use with the Netronics ELFII (RCA COSMAC 1802) and Netronics Explorer kits c1978. Modded by addition of power & shiftlock LED indicators. I really must replace those clumsy brass bolts with something more discrete.

An early (Minolta) digital compact camera. The electronics are advanced but the big difference today is the physical size of equivalent compact cameras. However, you rarely get such good inbuilt compact camera lenses.

Since I haven't uploaded anything to Flickr in quite a while, I decided to go through my camera and upload a few interesting pictures.

 

This picture is one of four I'm uploading about my AP Physics B final project: To correctly wire a circuit that, when hooked up to a pre-built power supply, acts like a clock, lighting up LEDs per second to indicate time.

 

This picture shows the topside of the board. Visible are the ten LEDs, the 1 microfarad capactior, the 10 kiloohm resistor, and the seven 14-pin inline integrated circuit sockets. Note that the integrated circuit chips (which were TTL logic chips) are not present in the sockets, since there were less chips than students available and I was finished testing my board. All components are held in place on the board by wire wrapping, with the exception of the seven sockets themselves and the three (not visible) vector pins, which were soldered in place.
