Outstanding steampunkish VFD wristwatch

Wristwatch projects are coll for many reasons. First of all how they are built – components need to be squeezed to make watch wearable. Another thing is display. What different types of displays can be used. LCDs and LEDs seems to be getting boring, unless they are used in some weird way. Other things also are important like overall look, power supply , features and controls. Johnengineer has been working on steampunk wristwatch for couple months and he came up with something awesome. The unique idea was to use IVL2-7/5 VFD display. They are relatively small to fit on a watch and pulls out relatively small amount of current. It also requires low grid voltage (~12V). Display is transparent, so background PCB is visible and this can be considered a… Continue reading

Stylish steampunk LED wristwatch

This LED wristwatch uses old fashioned LED displays that look really cool. They have some similarity to nixies if look closer. The heart of watch is PIC16F628A microcontroller with separate oscillator to keep track of time. The watch has also two buttons for setting time. It is powered with two button batteries. In fact this is pretty simple watch with no fancy features but it looks great when it sits on a hand. Continue reading
