Autonomous Bassline Generator
Builder's Guide 1.0.2
Step 1: Get comfortable
Look at the graphical parts list, compare the parts you have to the pictures and make sure you can
identify every component. Look at the color bands on the resistors. Read the numbers on the other
components.
It's also a good idea to spend a moment getting familiar with the PCB, too.
Pull out your tools: soldering iron, solder, flush cutters, maybe needle-nose pliers.
Take a deep breath.... here we go!

- Page 2 Step 2: Resistors Insert and solder the 10 resistors: 100ohm x 1 • 330ohm x 3 • 10k x 1 • 47k x 2 • 220k x 2 • Optional: • ◦ 47k x 1 for "-R-" ◦ Note: the spot marked "-R-" is a tweakable resistor. Changing its value will change the analogue filter.
- Page 3 Step 4: Capacitors, Transistors, Photocell Insert and solder the capacitors, transistor, and photocell:: 1uF x 1 • 10uF x 1 • 100uF x 1 • 0.1uF x 1 • 0.01uF x 2 (for "-C-", or use the socket. See note) •...
- Page 4 Step 6: Bottom-side stuff On the bottom side, solder: 1/4" audio jack • IR receiver (the black LED- • looking thing) IR LED x 2 (box "sidelooker") • Note 1: Snip the leads of the volume trim-pot before soldering the jack. You only have to solder the 3 square pads on the jack, and it's easier to solder some of the pads from the underside...
- Page 5 Step 8: Standoffs Nylon Legs: Insert the four nylon legs into each corner hole, and tighten them down with a nut. Step 9: Final touches Insert the two ICs: The ATtiny84 has a notch on the end that matches the silkscreen "notch" on the PCB (points •...
