This is the Edison clock, designed by [David Krawczyk]. It shows time in the same way as the multimeter clock, regulating power to two analog needle meters. The feature that makes this one a bit different is the alarm. You can see the series of holes on the front of the base. These have a small light bulb socked in each, and correspond to hours and 5-minute increments. Insert two bulbs to set the alarm time, and make sure that the alarm knob points to ‘on’. As you can see above, the alarm has been set to 8:15. Hidden on the last image of the article above is a PDF with just a bit more explanation. Still, much has been left out so if you replicate this clock we want to hear about it.
Nice work. Now if only the bulbs were completely sealed, that would be bada$$.
I’d remove the alarm on/off switch and just use the bulbs as the trigger. Not sure if there is an alarm sound to go with it but could use the fact that the circuit is closed and there is current going through it to drive a buzz relay connected to a speaker. Also, Edison was DC only!
screw edition he was a jurk XD Nikola Tesla contributed SOOO much more to science at the same time!
I wish I could get up at 8:15 :/ that’s like, sleeping in for HOURS in my house.
Id rather see a Tesla Clock…
Time displayed by a set of jacobs ladders and the alarm is a tesla coil lighting off loud sparks.
That is sweet!! I would love one of them. But i am stuck with the worlds first alarms that was made in the beginning of time. A wife.
I wish there was some diagrams or ways to build this
i’d love to tackle it
Tesla clock would be cool.
BTW Edison hired Tesla wayback when, he left because of a stupid decision by Edison not to pay out the money for redesigning a motor that he agreed to.
IMHO that was the worst decision in history on Edison’s part, the money would have been pocket change.
