Page 3: Overview
(for beach-combers, werewolves). There's also a built in battery meter so you can check your battery life. Want to make your own watch? Easy! The © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 3 of 32 Industries...
Page 4 Arduino-compatible, all you need is an FTDI Friend and the Arduino IDE and you can design your own watch faces and upload them to the TIMESQUARE. (http://adafru.it/aT9) Engineered for greatness by PaintYourDragon, this watch squeezes over 1000 full time displays out of a coin battery, and a 1+ year 'resting' lifetime, so you can use this as a day-to-day time keeper.
Page 5 (http://adafru.it/aTa) Take about 1-2 hours to put together. Build it in the afternoon and you'll be done in time to hit the clubs in the evening. © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 5 of 32 Industries...

(see here (http://adafru.it/aOo)). Click here to buy our entry level adjustable 30W 110V soldering iron. (http://adafru.it/180) Click here to upgrade to a Genuine Hakko FX-888 adjustable temperature soldering iron.

Page 7 Flush Diago nal Cutters You will need flush diagonal cutters to trim the wires and leads off of components once you have soldered them in place. Click here to buy our favorite © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 7 of 32 Industries...
Page 8 Click here to buy a one. (http://adafru.it/148) Helping Third Hand With Magnifier Not absolutely necessary but will make things go much much faster, and it will make soldering much easier.

Parts List TIMESQUARE PCB - half thickness black PCB ATMEGA328P - preprogrammed microcontroller DS1337 - 8 pin real time clock chip 32.768KHz Crystal - thin silver cylinder Right angle buttons - two for either side 20mm coin battery holder 0.1uF ceramic capacitor - yellow blobby...

Page 11: Kit Assembly
R10 in the bottom right corner shown here Bend the wire leads out so the resistor sits flat against the PCB. Then you can flip it over and it wont fall out! © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 11 of 32 Industries...
Page 12 This keeps them from shorting to something else. Use diagonal or flush cutters to clip the wires right above where the solder joint ends. © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 12 of 32 Industries...
Page 13 R10 resistor, so its surrounded by the C1 outline Then bend the leads and flip over the board. Solder in the capacitor's two legs just like you did with the resistor © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 13 of 32 Industries...
Page 14 - Yello w Vio let Black Go ld Here we placed and soldered all 8 at once but you can go one at a time if you want to take it a little slower! © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 14 of 32 Industries...
Page 15 Solder in all the resistors, either one at a time or all 8 at once! Make sure you don't forget any solder points, though. © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 15 of 32 Industries...
Page 16 Look for the end of the chip with a notch and a dot. These must match up the silkscreened image on the PCB so make sure the notches line up. © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 16 of 32 Industries...
Page 17 Like the RTC, this chip must be put in the right way. The notch on the chip must go on the left side as in these photos. Check twice to make sure you have the chip in right! © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 17 of 32 Industries...
Page 18 The battery holder does have a special way it must go, make sure you can slide the battery in by having the open side facing out The crystal can go in either way, its symmetric, like the resistors © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 18 of 32 Industries...
Page 19 Flip it over and solder in the other battery pin, then go back and do the first one. Also, solder and clip the two crystal pins © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 19 of 32 Industries...
Page 20 PCB with a dot as you see here. Also the matrix goes on the OPPOSITE side of the other parts! Check that the 28-pin microcontroller pins aren't in the way of the matrix, it should sit nice and flat © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 20 of 32 Industries...
Page 21 (they're less long than the height of all the other parts! Get the remaining parts out of the kit - a 20mm coin battery, silicone band and optional clear plastic back © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 21 of 32 Industries...
Page 22 When you've got it all in, you may need to pull/press the band around the PCB to have the 'nubs' fit into the notches that are molded into the band © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 22 of 32 Industries...
Page 23: Adjusting Fit
Another easy way to adjust the fit is to remove the plastic back - its not essential and for smaller wrists it may make the watch a little bulkier than desired. © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 23 of 32 Industries...
Page 24: Other Tweaks
LEDs that they shine through with little difficulty, while most ambient light is blocked. Rubylith film (from a decent old-school art supply store) would probably work as well, if not better. © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 24 of 32 Industries...
Page 25: Setting The Time
If using the watch for the first time, or after swapping batteries, it may wake in time-setting mode automatically. Tap ® ® or ← ← tap Hold ® ® ← ← 2 sec © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 25 of 32 Industries...
Page 26 The range for each digit varies, and the watch will keep the values in check. There is no seconds adjustment. Seconds will be reset to zero when exiting time-setting © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 26 of 32 Industries...

Page 28: Hold ® 2 Sec Or ← Hold 2 Sec
Inspired by the famous Dow Jones news ticker, this scrolls the current time from right to left. Tap either side button while active to switch the display from time to date. Tap again to show the time. © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 28 of 32 Industries...

This happens when the battery vo ltage runs lo w. It’s no rmal behavio r, an attempt by the watch to preserve battery life. Allo w it to rest o r replace the battery so o n. © Adafruit http://learn.adafruit.com/timesquare-watch-kit Page 29 of 32 Industries...

PCB, to match this photo. Be sure to have a battery in the watch, as it does need to be powered while programming! Next, download the TIMESQUARE watch codebase from github. Visit the github page and click on (http://adafru.it/aT8)DOWNLOAD (http: //adafru.it/aT8) (http://adafru.it/aT8)
