Alarm demonstration 
December 16th - via: kickstarter.com
Hi all, Today I'd like to show you the setup of Alarm function. The Max sound level is set to 4 (out of 10) and the snooze duration is set to 5min. These 2 settings are part of general menu, and video won't show them. The Alarm would raise the beeps... (Read More)
Alarm sound levels
December 15th - via: kickstarter.com
Hello, Here's a short video showing the Alarm sound test. The buzzer is externally driven, and it is quite loud (93dB from 10cm) when being run at resonant frequency of 2.83kHz. I've tested the alarm at 10 discrete sound levels. The ON/OFF square... (Read More)
Pushbuttons and more resolved...
December 14th - via: kickstarter.com
Hi all, 3 things in this update: 1) the side pushbuttons I will make a 1/8" rod and disc and a short tactile switch. It looked better to me (more appealing, being transparent like the rest of the clock enclosure, and being tad bit longer, too).... (Read More)

Hello, I've ordered today acrylic tube. My friend machinist convinced me it would be best to bolt the sides to the cylinder with 3 stainless steel screws with button cap heads 4-40x1/2" spaced 120 degrees apart - see the figure below: side view The... (Read More)

new board being debugged
November 30th - via: kickstarter.com
no colons yet Oh boy, I'm having fun! I had to lift the clock chip to enable ISP (in system programming) - the 2 cannot share the same pins (at least not at the same time). Anyhow, I will make all routines working, and then add the clock at the... (Read More)
Got the new boards!
November 28th - via: kickstarter.com
Hello, got the new PCBs yesterday - and worked tirelessly yesterday and today to populate the new design. As soon as got the SMD components soldered and reflowed I cleaned the board in ultrasonic bath, and soldered the rest of the components. Here... (Read More)
making colons
November 23rd - via: kickstarter.com
Hi, I've made a tool to cut the viols precisely to the same length and pre-made the bases with pins (total of 20 colons). I assembled and tested 10 colons, until I ran out of miniature neon lamps. I don't think I will make that many clocks anyway.... (Read More)
First colon made!
November 19th - via: kickstarter.com
Hi everyone, It took me like 3 hours to make the first colon. The 3D printer clogs the tiny holes somewhat, so I used my jewelry drill press to open up the holes, then I pressed the pins, trimmed neon lamp wires and soldered them - see pic below;... (Read More)

Alarm function will be added
November 11th - via: kickstarter.com
Hi, I've received few mails asking about the alarm on this clock. Since I couldn't free up any IO pins on the MCU (Atmega88 was tapped out to the point that I was using 1-out-of-10 BCD decoder/IO expander). I've decided to upgrade MCU to Atmega16A... (Read More)
