TT555 Soldering Kit now available on Tindie!

Probably the most-viewed post on this blog so far has been my project to construct a discrete-transistor replica of the 555 timer IC. I’m pleased to report that, due to popular demand, the TT555 is now available in kit form!

This is your chance to prove that you’re a real SMD soldering expert: to assemble it, you need to place 43 components onto a 10×10 mm2 PCB, pick and place 01005 size resistors (0.4×0.2 mm2), and solder DFN-1006-3 packages (1.0×0.6 mm2). A microscope, sharp tweezers and a fine-tipped soldering iron are essential tools to complete this project.

Included in the package are:

  • One bare TT555 PCB
  • One set of thin pin headers
  • All resistors and transistors needed to assemble the circuit, including a few spares of each component
  • Extensive documentation

All documentation is also available online:
