I took apart a cheap calculator I had and I didn't expect to see this. I thought i'd be looking at a solderable circuit board with electronic components such as resistors, logic gates and a microcontroller all soldered/screwed in.

I'm a beginner with electronic/computer engineering and i'd love to have somebody shed some light. What type of circuit am I looking at and how far in terms of years for electronic/computer engineering must I pass to have the capability of creating such a circuit?

Thanks,

What does the other side of the board look like?

The pcb is cheaply made - don't expect to be able to do anything with it. The big black glob you see on the back is where the microprocessor is (it's under it). The small yellow-y block things with c1/c2 are some capacitors that are soldered on. Same with the R.

I would suggest investing in an arduino, or just a kit of discrete components if you want to build circuits.
