[edit] Soldering Tips

We are bringing back the days when men were men and soldered their own stereo equipment, except we include women.

• LEDs will NOT work if installed backwards due to polarity, the longer side of the LED goes in the + hole.
• Use caution when handling the hall effect sensors as they are sensitive to static electricity. Note that each hall sensor has a beveled side (usually printed on as well). This side should be soldered to face away from the magnet as it passes by.
• IPC offers a training and certification course in "Hand Soldering for Through Hole Components (Tin-Lead Solder)" and a DVD-42C. Here is a link to a free video review of the course.
• Width of the tip should be equal to the diameter of the "land" that is being soldered.
• Solders should take an average of 3 seconds, otherwise you risking heat damage.

[edit] Parts & Tools

The right tools and beer make things go easier.

[edit] Assembly

You need to assemble one USB Interface (Main) Board and four Sensor Boards.

[edit] USB Interface (Main) Board

The Main Board, aka the USB interface board. Not to be confused with a Network Hub.

See Main Board Assembly Instructions.

[edit] Sensor Boards

You need to make one of these roller sensor boards for each bike. OpenSprints Kits come with four by default.

See Roller Sensor Boards Assembly Instructions.

[edit] What's Next?

Now that your hardware is fully assembled you need to install two things:

1. Update Arduino with OpenSprints Firmware if you haven't done so already.
2. Install Software on a netbook or USB Thumb drive.
