I like the pic, atmel is ideal for people who do not have little to do with programming programs without any microcontroller LPT port of the computer with lcd displays, HD44780 chip KS0108 or through the test. There are a couple of Test circuits, resistance, diode.
KS0108 128 × 64 glcd test may be sent in writing, picture (bmp) file as a C-language header information can also register.

800ma Power Supply Circuit LD1117
LM317 LD1117 series, 78xx regulator fixed output voltage of the regulator IC in a similar or models have adjustable LD1117 production of SGS Thomson LM1117 national production also produces in different companies, but I do not remember the exact names.
SOT-223 SMD type sheath used in practice LD1117 power 9v 800mA from 1.25V voltage adjustment can be made.
