Common choices are annoying beeping, energetic marimbas, or what used to be your favorite song (which you have now come to despise).
We suspect that most of us who use an alarm clock have our particular sound memorized. If Nixies aren’t your thing, you can also make an alarm clock with a VFD tube, or even roll your own luminous analog dial.Ĭontinue reading “Retro Alarm Clock With Nixies Is Thoroughly Modern Inside” → Posted in clock hacks Tagged alarm clock, current source, nixie, nixie clock ’s GitHub page has all the schematics as well as extensive documentation describing the circuit’s operation - an excellent resource if you’re planning to build a Nixie project yourself. The mainboard and the display are housed inside a 3D-printed case that mimics the style of 1980s digital alarm clocks, but with a nice 1970s twist courtesy of those Nixie tubes. The individual segments are switched by SN75468 Darlington arrays, with no need for those hard-to-find SN74141 drivers. Instead of using the standard current-limiting resistor for each Nixie tube, designed an array of transistor-based current sources: this enables linear control of the tubes’ brightness, and should keep the amount of light constant even as the tubes age. The 180 V needed for the Nixies is generated by an MC34063A-based boost converter, which also powers the neon tubes. Of course, the real party piece is the clock’s display: four IN-4 Nixie tubes show the time, with neon tubes indicating the day of the week.

A 2 x 3 W class D audio amplifier plus a pair of stereo speakers should be able to wake even the heaviest sleepers. It keeps track of time through its real-time clock with battery backup, and plays a song from an SD card when it’s time to wake up. The clock and alarm functionalities are implemented by a PIC24 microcontroller on a custom mainboard. In any case, we’re delighted to bring you ’s beautiful Nixie tube alarm clock that cleverly combines modern and classic technologies in a single package. Maybe that’s because no-one enjoys being woken up in the morning, or simply because everyone uses their smartphone for that purpose already. We feature a lot of clocks here at Hackaday, but alarm clocks seem to be less popular for some reason. Continue reading “IO Connected Radio Alarm Clock” → Posted in clock hacks Tagged alarm clock, AM/FM, atmega328, atmega328p, DS1307 RTC, i2c, TEA5767 Since the RTC has an auxiliary coin cell battery for power, the alarm clock can keep accurate time even when not plugged in. The audio output of the TEA5767 feeds directly into the TDA7052 audio amplifier to drive the speakers. Most of the electronics are powered using 5V except for the TEA5767, which is powered from the 3.3V rail and has its I2C communication levels shifted from 5V to 3.3V. The main power comes from a 9V power source with an LM317 and LM7805 linear regulators providing a 3.3V and 5V power rail, respectively.

Every closed file handle on the filesystem that had a write flag open initiates the event check.Creates an alarm clock that includes features one might expect in such a project, including an FM radio, snooze button inputs and a display, but goes beyond the basic functionality to include temperature sensing and a PC connection, opening the way for customizable functionality.Īn Atmega328 is used for the main microcontroller which communicates via I2C both to a DS1307 real time clock (RTC) and a TEA5767 FM module.
