mini-DIN 6 breakout

2 layer board of 0.90 x 0.60 inches (22.9 x 15.3 mm).
Shared on January 6th, 2017 01:39

Accepts a CUI MD-40S or MD-60S. For the 40S, use pins 3-6 (corresponds to pins 1-4).

GPS Disciplined FE-5680A v1.6.4

2 layer board of 4.00 x 2.05 inches (101.6 x 52.1 mm).
Shared on July 7th, 2016 02:53

See the Hackaday project page.

Almost the same as v1.6.3, but adds pi network to one output for a 13 dBm into 50 Ω sine port.

Divide-by-3

2 layer board of 1.00 x 1.25 inches (25.4 x 31.8 mm).
Shared on June 18th, 2016 22:25

I have a 15 MHz Oscillator. My TIA accepts 1, 5 or 10 MHz. This board is a divide-by-3.

  • IC1 & IC2 - dual D flip-flops
  • IC3 - quad 2 input NOR gates
  • C1-3 0.1µF

Inspiration came from here.

I can reflow! badge

2 layer board of 2.01 x 2.01 inches (51.0 x 51.0 mm).
Shared on June 17th, 2016 14:33

This board has the traditional 2 NPN transistor alternating oscillator circuit… but with SMD components to proudly proclaim your achievement!

  • Q1 & Q2 - MMBT3904
  • R1 & R2 - 0805 100Ω
  • R3 & R4 - 0805 100kΩ
  • C1 & C2 - 0805 10µF

And two 0805 LEDs and a CR1220 battery clip.
