Kit ASSEMBLY INSTRUCTIONS BILL OF MATERIALS (V1.2) Th i s DI Y kit assembly guide assumes that the builder is familiar with basic thru-hole soldering techniques and has the abilit y to identify and mount the electronic components included. A resistor color-code and capacitor code cheatsh eet has been inc luded for ease of reference. A complete bi ll of materials are included on the opposite column D i ode s D1, D9 D2 D10 D3*, D4*, D5*, D6* D7, D8 If you’r e new to DIY elec tronics kits or find anything co nf using a bout these directions, please visit ww w.l zxindustries.n et/p roducts/bitvision for links to h el pful r esources and v ideos about soldering and compon ent identif ic ation.

Solder and clip leads. 2 ) Mount all resistors, solder and clip leads. We recommend d oi ng a few at a time. 3 ) Next mount IC1, IC2, IC3 and IC4. Ensure that the notch o n the top of eac h c hip matches the orientation of the notch sh own on t he PCB s ilkscreen. Solder and clip leads. Take ca re t o not ov erheat IC pins while soldering, and to not d i stur b t he pre-soldered surface-mount diodes near IC2’s p i n s. 4 ) Mount Q1. Solder and clip leads. 5 ) Mount IC5, bending pins so that the protruding metal p or t ion of the TO220 package is flat against the circuit b oar d. Solder and clip leads. 6 ) Mount D7 & D8 LEDs , taking care that the shorter of the two leads ( the c athode) is oriented towards the left side of the PCB ( while oriented as shown on the previous column.) Solder and clip leads. 7 ) Mount all ceramic capac itors, solder and clip leads. We recommend doing a few at a time. 8 ) Mount both electrolytic capacitors, ensuring that the long lead ( positiv e s ide) is placed thru the square solder pad with the + sign nex t to it. Solder and clip leads. 9 ) One at a time, mount jac ks, headers, potentiometers and sw itches and solder in plac e. We recommend to solder only o ne pin f ir st, then c heck to make sure the part is resting fl u sh against the PCB. If not, the joint can be reflowed and the par t r epositioned before soldering in the remaining pins a nd mounting tabs . 1 0) Inst all a resistor lead c lipping as a wire bridge across the pins shown under the resistor diagram to the right.
