00:00Hey everyone! If you love tinkering with electronics, building custom Arduino gadgets,
00:05or just stocking your workbench, you already know how fast you burn through dials and audio alerts.
00:11Today, I've tracked down the best deals on the top 5 potentiometer and buzzer prototyping sets
00:16to help you save cash while keeping your maker bin completely full. Let's jump right into the
00:21lineup. First up is this 10-pack of SFM27 Active Piezo buzzers, and let me tell you,
00:27these definitely do not whisper, they belt out a piercing 90dB continuous tone that grabs
00:32attention immediately. The wide 3-24V operating range makes them super versatile for everything
00:39from 12V vehicle monitors to DIY home security systems. Coming in at around $15.67 for the set
00:46with a solid 5-star track record, they're the perfect grab-ango solution when you need clear,
00:51fail-safe acoustic alarms. Next, you need something to finish off your rotary controls,
00:56and this 30-piece WH-148 knob cap set is a game-changer for clean builds.
01:02What makes these stand out from cheap plastic caps is the brass copper core,
01:06which bites down securely onto 6mm splines without slipping or wobbling.
01:10You get 6 distinct colors across the pack, perfect for color-coding mixer channels or power supply
01:16trims, and at only $3.72, it's an effortless aesthetic upgrade for your front panels.
01:22Now, to go along with those knobs, here's a 20-piece WH-148 linear potentiometer kit that every DIYer
01:29should have on hand. The standout feature here is the broad variety of resistance values,
01:35from 1K up to 1M, meaning you'll always have the right component for testing audio filters,
01:40sensor inputs, or voltage dividers. It includes all the matching mounting nuts and washers for easy
01:45panel installation, and at just $6.84, it saves you from waiting on separate parts shipments mid-build.
01:52If you just need loud, straightforward audio alerts on a shoestring budget,
01:57take a look at this 6-pack of SFM20B active buzzers. Even with their compact design,
02:02they manage an impressive 95 dB continuous beep that cuts straight through workshop noise.
02:08Because they're active units running on 3 to 24 volts, you don't even need PWM tone code,
02:13just send a high-logic pin from your microcontroller, and you're good to go.
02:18At an unbeatable price of just $1.35 for 6 units, tossing these into your cart is a total no
02:24-brainer.
02:26Rounding out the list is the heavy-duty 30-set WH-148 potentiometer assortment kit,
02:31tailored around the most popular values like 10K, 50K, and 100K. With 30 individual pots plus all
02:38the mounting hardware in one bundle, it provides plenty of runway for ambitious synthesizers,
02:43custom guitar pedals, and lab prototypes. The smooth rotation feels great to dial in,
