While the highly-regarded Pong clock has long held the crown for most intriguing DIY clock, it looks like the leaderboard could be seeing a change. Frank Techniek's interesting oscilloscope conversion is yet another prime example of turning vintage (or otherwise idiosyncratic) kit into a modern day gadget, and the 20MHz TRIO that once read signal voltages for a living is now enjoying an unusually time consuming (ahem) retirement. Per usual, this expert-minded endeavor involved more circuitry, soldering, resistors, and time off than we have room to explain, but if you're interested in propping one of these up in your den, be sure to hit the read link for the nicely detailed bill of materials and assembly instructions.
