I just came across this neat video on youtube, which shows some basic smt components sizes like resistors &capacitors 0201, 0402, 0603, 0805, 1206 and TSSOP56 IC. The quality is great and I really recommend it to beginners.
This project will make use of the MAX6675 Cold-Junction-Compensated K-Thermocouple-to-Digital Converter. It basically takes the millivolts produced by a standard K-type thermocouple, amplifies it, and outputs it’s temperature reading. This reading is received by a microcontroller, which then displays the reading on an LCD display. This unit will be capable of reading temperatures up 1800 degrees fahrenheit.
As you can see the author of this project also used adapters for smd parts. Myself i like to work directly with SMD parts, but sometimes it’s just not possible, especially when prototyping because you always have to tweak something.

The circuit uses a constant current drive and a four wire connection to the probes. This allows almost any length of probe connecting cable without re-calibration. Surface mount chips are wonderful, but for prototype work these can be difficult to use. If you only have SMD parts available to make it easier you can construct a SO to DIP adapter.

With the advent of high-output, relatively-inexpensive white LEDs, it is possible for a hobbyist to make a miniature solid-state ring light with surface-mount technology. The LED ring light featured in this article costs about $10 in parts (PCB, LEDs, resistors, wire, and solder). If you’ve never tried soldering surface-mount parts, this is an excellent project to start with.

This SMD op-amp project uses the TI RC-4560 dual op-amp chip and a salt water-etched PCB. The builder got the op-amp as a free sample from Texas Instruments and scavenged all of the SMD resistors from old hard drive electronics. The results are not pretty, but they’re functional. The circuit used (with some changes) is the Chu Moy design found here. The CMoy circuit is not SMD.
