00:00So you're building your own intercom, maybe a door phone, a two-station rig for the workshop,
00:04whatever it is, and you need a mic capsule that won't let you down.
00:08Well, I went down the rabbit hole for you, and I found the best deals out there.
00:13Here are my top 5 electric mic capsules for DIY intercoms.
00:17First up is this 20-pack of 6,050 capsules, and the standout feature is the waterproof
00:22insulation, so if your intercom's living on a front door or anywhere with moisture,
00:26these can take it. They're the standard 6x5mm size, and they come with the 2-pin 1.25mm leads
00:34already attached, which honestly saves you from soldering those tiny little pads.
00:39853 gets you 20 of them, and with over 4700 sold at 4.6 stars, plenty of builders clearly trust
00:45these.
00:47Next, and this might be the deal of the whole video, 59 cents for 10 capsules.
00:52That's about 6 cents each, which is almost silly.
00:55It's a mixed grab bag 2, 4.5x2.2, 6x2.2, 6x5, 9x7, the 4013s, 6022s, 6050s, 9070s,
01:07all sitting around 52 dB sensitivity. Perfect if you want to experiment with
01:12different sizes before committing to a design. Nearly 4500 sold with a 4.8 rating says it all.
01:19Number 3 is where things get a bit more serious, these 6050 capsules run at 56-58 sensitivity instead
01:26of the usual 52, so they're noticeably hotter. Quieter voices actually come through clear on the
01:32other end, which is exactly what you want in an intercom. You get the classic 6x5mm size with the
01:39center pin and tape mount. 331 for 10, over 4400 sold, and a perfect 5-star rating.
01:47Number 4-20 Electrid Mic Inserts with Actual PCB Pins
01:52If you're designing or etching your own board, this is the one to grab, because the legs drop
01:56straight through the holes and solder in seconds. No wrestling with surface pads under a magnifying lamp.
02:04276 for 20 works out to about 14 cents a capsule, with 4200 sold and another flawless 5 stars.
02:11And finally, the big boys, 9x7mm capsules, 10 of them for 227. That extra real estate gives you a
02:19fuller, warmer voice on the receiving end, and in an intercom, that's the difference between
02:23someone's at the door and actually recognizing who it is. They also come in the smaller 6x5 size if
02:30your enclosure is tight. 2800 sold, 5 stars across the board. All 5 of these are linked down in the
02:37description, those prices do move around, so don't sit on them too long. If this helped your build,
