Needing a solar (photovoltaic) cell quickly for a project, I bought a cheap (£1) calculator with the solar cell clearly visible on the front.
When I took it apart, however, something was wrong: there were no wires leading fom the cell. Prising a black backing plate off revealed that the 'cell' was in fact a shiny transparent piece of plastic about an inch long with maroon/brown blocks printed on the back, with gaps left between them specifically to simulate the appearance of a real solar cell.
I wasn't quite sure whether to laugh or be annoyed. Why would a company bother to design and manufacture the fake solar cell? With calculators selling for £1 each it's surely unlikely that deceiving the customer in this way would make much difference to sales... so really, why did they bother?
Was it a conscious decision - "we can charge more for this if people think it's solar-powered"? Or was it just that other calculators have them so it was thought that this one ought to, even though it was fake?
This - www.alibaba.com/catalog/11270592/Desktop_Calculators_Stoc... - looks to be the same or a very similar model, with the text expressly describing the "dummy solar" as if it is a feature.
(And yeah, when I actually looked more closely at the box the calculator came in - after taking it apart - I did see the "Solar cell are dummy & only for decoration" text.)

My dad still has his first calculator. It's from the 70s and it's pretty huge considering how calculators look now. Dad says this cost him about $400!

I imitated a the compostition of a Hongkong postage stamp. The image on the stamp was originally a combination of a modern calculator and an acient Chinese abacus, which I found quite interesting
The AU version is limited to only 4.5MB of its 16MB capacity, in order to comply with SA school exams.
I've installed Ptune3 and sped up its processing by 50%!
I'm definitely turning into a calculator nerd - only a matter of time to finding a HP Prime G2 on my photostream...

Hewlett Packard HP-32Sii - two versions: Indonesia and Singapore with different colour combinations. The quality of the Singapore version is better.
Power Supply and clock PCB. The 4 ICs are TTL devices to generate the system clock signals. The pot core on the left is the power converter transformer to generate the voltages needed by the PMOS ICs and the display. The 4 power transistors in the top centre are part of the power converter, the single one on the right is in the battery charger circuit. The plug on the left (white wires) carries the display voltages to the scan PCB, the one on the right (grey wires) connects to the battery holder
The Biolater was not Y2K compliant and displayed valid dates for the 1990s only as it is a two-digit year entry system.
The Casio Biolater dates to around 1976 based on newspaper advertising. It was advertised as the body computer that charts your good and bad days, It is also a four-function calculator (add, subtract, multiply and divide). The Biolater had an advertised price of $29.95 in 1976.
Vector calculator is vastly used concept in math as well as in science. Vector Calculator is a very useful online tools for students. Put the values and get the answers, not delay. Vector involves some operations like addition, subtraction etc.
A major improvement on the abacus and much larger versions of calculators, these can perform simple math functions all the way to calculus equations. © JoeHaupt / Wikimedia Commons / CC-BY-SA-3.0

Radio Shack/ Tandy had a line of 'pocket computers' in the 80's - these were re-badged Sharp and Casio PC's. I've owned the PC-8 (bottom right) new since 1988 - it was the first pocket computer in my collection.
Hewlett Packard 12C's have been in continuous production since 1981 - spot the differences between 1982 (top) and 2011 (bottom).
Lloyd's Accumatic 200 calculator from the mid-1970's. Unusual keyboard layout, with the "=" above the x. Similar to the 999 (same case and general layout), but without the scientific functions.
Open view, see other image for the decorated top.
I've decorated this pocket sized calculator with polymer clay, glass catseye cabochons, silver jewelry findings and faux turquoise cabs. After curing the polymer clay it was painted with metallic paint and secured to the calculator with a permanent adhesive.
It measures 3.75" 2.25"
