Merry Christmas!

To all friends, family, readers and random passers-by: Thank you for coming to my site and I hope you have a Merry Christmas and a Happy New Year!


This tree was decorated with the help of a few scrapped boards from the late 80s and early 90s. The red components are relays and there are a few electrolytic capacitors scattered throughout. The LEDs were scavenged from a display board and set to pulse with a Source Meter that was sweeping current from 0 to 10 mA. High precision resistors could also be found on the tree, although it may be tough to tell they were actually high precision. The star at the top of the tree was made from 5 DIP package op amps and one can op amp. The “tinsel” and “garland” was actually solder wick and solder.
