World’s smallest geiger counter watch

All the time I come across some really cool technology that I want to write about even tho it’s not related to Xronos Clocks. So I’m introducing “Misc Tech” category.

Today I wanted  to write about world’s smallest Geiger counter: PM1208 wrist watch made by Polimaster.  I have some high resolution pictures of the insides of the watch at the end of this post if you are curious.

I’ve always been fascinated by seeing “unseen” and radiation is just a thing. It all around us, it can kill us if levels are too high, but we have no way to sense it (at least not until it’s too late). So about 10 years ago I bought  wrist watch that could detect gamma rays.  Very expensive ($400) but also very cool!

Pinout connections schematic of Xronos board 2.x added

I’ve documented all pins of the main board used inside Xronos clock and organized in easy to read chart.It can be very useful if you plan to hack your Xronos clock or just use standalone board for your projects!

You can download schematic here, or view on the Technical Data page.

Kudos for inspiration and pin labeling goes to Felix from LowPowerLabs and “PigHixxx”

Say hello to Xronos Mega

There’s something that I’ve been working on besides Xronos Alarm Clock for the past 6 months.

A little story behind it goes like this.

I don’t have any wall clocks, so I had a store bought alarm clock (Emerson?) with very large digits (biggest I could find) to serve as a time piece by the TV. Just about when I was getting Xronos V1.0 to see the light that “TV” clock died. And so I started to outline a wall clock that will be really big, with tons of features, remote control, and huge LED matrix display.  Thus Xronos Mega Clock was born 🙂

In the end I settled on four 24×16 single color LED matrix displays made by Sure Electronics. Originally I wanted to use same display as in Xronos Alarm Clock (32×16 bicolor): 2 on top would give me 64×16 space for clock digits and then on the bottom I wanted to have a single 8 height row for the scrolling messages that would display date, temperature, etc.  Then I realized it’s going to be huge pain in the butt to drive different arrays from ATMega chip, so I settled on four 24×16 displays.
