Microsoft Empire



Found this diagram somewhere on the Internet.  As it is said on the top, it is permitted to repost here.  Very true and interesting!

My new Workbench is ready


Finally, the SMT Soldering station "X-TRONIC 9020" I ordered from Amazon has arrived.  I did quick test on both hot air iron and the regular soldering iron.  Both now work fine.

New workbench for SMT works


My workbench (modification is still ongoing...waiting for the SMT solder tool to come.  My new multi-meter is not yet shown there).

Oscilloscope: 100 MHz Tektronix 2232 (spec) (bought it from eBay)
Digital Analyzer (bottom left): Tektronix 1241 (bought it from eBay)
Multi-meter: UT61C (with RS232C connection), and two others (older ones, not seen)
SMT Soldering station: X-Tronic 9020 XTS (not-seen).  Bought it from Amazon
Solder: Weller-SPG40 (on the bench) and SPG-100 (not seen as it is behind the lamp)
Power-supply: CircuitSpecialists CS11802X 0-18 V, 0-2A variable power supply
Vise: PANAVise
Small breadboard: TI msp430 LauchPad connected with my seven-segment circuit on breadboard
Board in the middle: PIC887A development board, measuring temperature and displaying it on the 16x2 LCD as well as sending the temperature to RS232.
Big breadboard: the old prototype of the same function as the PIC protoboard above.

Wishlist:
Digital Storage Oscilloscope with 100 MHz bandwidth
Higher frequency measurement for multi-tester (the UT61C freq. range is only 0-10 MHz, while UT61E has 0-220 MHz range)
Microscope 25-95x (this one looks cool for my bench, except I may not have space left)
