Build Instructions, Printable Version
Step 0: Gather Tools
To build the Tactile Metronome, you will need a few common tools for soldering and electronics work. A
soldering iron and solder are the most important tools. You can use any soldering iron, although a higher-
quality, temperature-controlled adjustable iron will be easier to work with and give higher quality results. Any
standard solder for small electronics will do just fine.
To bend the leads of the push buttons, you will need a pliers or similar tool. We used the pliers on a wire
strippers. To trim the extra leads on the bottom of the pcb a diagonal pliers will work very well.
If you need some additional guidance and instruction on soldering, SparkFun, NASA, and

- Page 2 Step 2: Push Buttons The push-buttons are used to adjust the settings of the Tactile Metronome, including pattern tempo and beep pitch. Use a pliers to straighten the legs of the buttons. They don’t need to be perfectly straight. We want the plastic base of the button to press right up against the PCB.

Build Instructions, Printable Version | Wayne and... http://www.wayneandlayne.com/projects/metron... Use your soldering iron to heat up the leg of the button and the ring around the hole at the same time. Push a little bit of solder on the ring. The solder should melt and flow around the hole. If you’re having trouble, make sure the tip of your iron is tinned and shiny. - Page 4 Build Instructions, Printable Version | Wayne and... http://www.wayneandlayne.com/projects/metron... To solder things with long legs like this, you can turn the board over and bend the legs a little bit, so the component doesn’t fall out while the board is upside-down. Solder the both legs to the PCB.

Make sure the displays are firm against the board, and check for alignment.If the displays are crooked, you can reheat the junction and nudge the display. When you’re happy with the alignment, solder the remaining legs of the displays.

The footprint on the board is labeled J1. There is a notch in one end of the socket that should line up with the notch in the drawing on the PCB, next to the ceramic capacitor (C2) that was just installed.

Same goes for the power switch (SW1) . Both parts are not polarized, and can go either way into the board. There’s a line on the resonator footprint, but please ignore it. It will be removed in the next board revision.

Step 11: In-Circuit Serial Programming Header (Optional) If you want to solder the ICSP header for reprogramming the microcontroller, you can do it now. You can use either a straight or right-angle header. The header is not provided. If you don’t have any header pins handy, you can unsolder the battery holder and attach the header later.
- Page 9 Build Instructions, Printable Version | Wayne and... http://www.wayneandlayne.com/projects/metron... Remove the paper backing from the foam tape on the battery holder, and insert the legs of the battery holder through the back of the holes in the PCB and slowly press the battery holder against the PCB. Be firm, but be careful not to warp the battery holder by pressing unevenly.

Step 15: Give the completed board a final look over, checking for loose solder connections or shorted pads. Congratulations! You’re now the proud owner of a Tactile Metronome. Install some AAA batteries and give it a try!
