Description:
The Solder : Time™ watch kit.
The Solder : Time is an original design watch kit that you solder and assemble yourself. Delivered as a through-hole kit, you solder the
components to the PCB, and enclose it all in four layers of laser cut acrylic.
Introduced at Maker Faire Bay Area in Mid 2011, an instant hit. The supplied battery lasts a really long time, and the onboard Dallas RTC keeps
impeccable time. This is the first SpikenzieLabs Kit that is a 'wearable'.
Solder : Time is not only a wristwatch. Set it up as a desk clock, badge clip-it to your clothes, thread a chain, and you've got a pocket watch.
More advanced tinkerers will see the bottom side I2C lines broken out, for hacking, and integrating RTC into other projects. There are also pads
on the backside of the PCB for DC supply, as well as an 'always-on' function.
Resistors:
Start by bending the leads to all three resistors to look like these in the photo.
Solder them in place and trim the leads. They go in either direction.
Clock crystal:
The crystal for the real time clock is the very small silver part with two leads.
Solder this as in the photo.
IC and Capacitors:
Note:
1.
1.
The notches on the two IC chips (RTC and PIC) must match-up with the notches printed on the white silk screen.
2.
2.
These two ICs are soldered directly onto the PCB. For best results, only apply heat from your soldering iron for 1 to 3 seconds per leg.
Solder the two orange-yellow capacitors in place.
Trim all leads.
LED:
Place the 4 digit 7 segment LED onto the PCB. Push flat, making sure all the legs go through the holes.
NOTE: Make sure that the LED is installed up-side right. Check that the decimal points are on the bottom as in this photo.
