Bend leads, solder, and clip excess. ### Step 4 — Solder LDR and Thermistor Make sure that these stand about 8mm from the PCB as it needs to pass through the top of the case to sense light and temperature. ### Step 5 — Install Capacitor and Crystal Oscillator Insert small round brown caps (22 and 104). They are not polarised so can go either way. ### Step 6 — Install DIP-8 IC Socket and DIP-16 IC Socket Insert sockets for ICs (don't install ICs yet). Ensure notch in socket matches the notch on PCB silkscreen. Solder all pins cleanly. ### Step 7 — Install Buzzer The underside of the buzzer has the + and - labelled. Make sue it matches up with the PCB ### Step 8 — Insert the PCB into the Case Make sure the LDR and Thermistor come through the holes in the top. Screw 4 screw to keep everything in place. --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
