Cool Tools: Adafruit Edition

SMT/SMD Resistor and Capacitor Books

Adafruit Resistor Book
This 0805 SMD resistor and capacitor book is just like the ones sold on eBay and just as useful. 0603’s are here.

Blank books and pages are here.

65 Piece Ratchet Screwdriver and Tool Bit Set

829-00

This 65 piece ratcheting screwdriver set is a bit nicer than comparable offerings from Dealextreme and includes bits for many of the obscure screws you are likely to encounter when disassembling all sorts of electronic equipment and devices.

Bus Pirate

Bus Pirate

I’ve used the Bus Pirate to troubleshoot tricky I2C bus problems and to develop automated testing of complex touchscreen control electronics. This is a small fraction of its capabilities. This is a handy item to have in your electronics toolbox. Has Python support!

Modular Snap Boxes

427-00

These snap boxes are available in several sizes and colors (including an ESD safe variant) and are great for storing loose components and fasteners.

Cool Tools: Elecfreaks SMD Prototyping Shield

elecfreaks_smd_protoThese SMD prototyping shields from Elecfreaks are pretty useful for building and testing discrete circuits made with mostly 2 and 3-terminal surface mount devices. I’ve used them quite a bit over the past year to prototype power supply and switching circuits (mostly SOT-23s). I like to cut them into small pieces with a large metal shear and stick them to larger PCBs (the ones I’m testing/modifying) with thick double-stick foam tape.

 

Cool Tools: Metcal MX-5211 Soldering Station

Metcal MX-6211
This is it! This Metcal soldering station will make you put away your Weller or Hakko and never look back! The dual simultaneous iron feature means you no longer need to buy two Metcal base units in order to solder SMT components with both hands! At over $800, these cost more than most hobbyists can afford. But for electronics professionals, this is probably the best soldering iron money can buy today. Just think, a year ago I had to buy two stations like this to fully equip a single lab bench for two-handed soldering!

Amazon.com seems to have the best price on these (free shipping for prime members!): Metcal MX-5211 Soldering and Rework System with 2 Hand-Pieces

Note: Tips are not included, but this iron uses the commonly available STTC tips that work with the older MX-500 series base units. Tips are not cheap, typically costing $15-$30 ea, but they will last for years of daily use if properly cared for.

I recommend the 700 series tips (STTC-1xx) for general leaded and lead-free soldering, although the tip life on the 600 series tips (STTC-0xx) is better and the lower temperature is fine for leaded solder and light duty use.

Here are some of my favorite STTC series tips:

  • STTC-125 – General purpose 1/32″ chisel, get this tip first!
  • STTC-117 – Beefy 5mm chisel tip. Like most of the fat chisels and conical tips, this will heat up heavy gauge wire scarily fast. Good for soldering heavy PSU or motor controller wires and ground planes. STTC-125P is also good for smaller stuff like SMD PSU caps and multi-pin connector grounds.
  • STTC-140 – Long reach angled fine point tip, great for general SMT work 0603 and below. I equipped my station with one of these and an STTC-125 and I rarely need to change tips.

Here’s a helpful selection guide that also shows just how many different tip styles are available.

If you just need one iron, the Metcal MX-5210 is cheaper and can be upgraded later.
