[0:00] Hey everyone!
[0:01] We’ve had our first mailbag!
[0:03] There’s a lot of stuff to unpack.
[0:05] I’m not sure this will be a regular thing.
[0:07] I do feel slightly guilty as I’ve sat on this box for over a month now waiting for some spare time.
[0:13] So, what’s in the box?
[0:15] We’ve got a good selection of linear regulators.
[0:19] These are really handy for audio projects where you want to try and isolate the power

[0:22] supply for the sensitive microphones and amplifiers from the noisy ESP32.
[0:28] And we’ve got a few DC to DC converters.
[0:31] Some nice little boards and the classic LM2596.
[0:36] There’s also a little switch mode power supply for connecting to the mains.
[0:40] I normally try and steer clear of mains voltages,

[0:42] but this could be handy at some point for a standalone project.
[0:47] On the ESP32 side of things, there’s a couple of nice dev modules

[0:51] along with the bare bones ESP32A1S module.
[0:55] I’ve actually got one of these on a dev board as well that I ordered last year.
[0:59] I’ll be trying to think of some good projects to do with these.
[1:03] Also in the box, there are a lot of microphones.
[1:06] I think someone is trying to drop me a hint - stop messing around with lasers

[1:10] and get back to some audio projects!
[1:13] We’ve got a good selection of MEMS microphones and a really nice collection of electret microphones

[1:19] including these ones that have been taken out of some shotgun microphones.
[1:23] To go with the microphones we’ve got a collection of microphone preamps to play with.
[1:28] We’ve also got some nice A2D Converters.
[1:31] It will be interesting to compare these against the built-in A2D converters of the ESP32.
[1:37] I think we’ve definitely got some interesting audio projects coming up.
[1:42] I’ve also received another interesting non-audio device.
[1:46] This is a magnetic rotation sensor.
[1:48] This came with a nice set of magnets to try it out with.
[1:51] I’ll use this to try and replace the mechanical rotary controller in my asteroids game.
[1:57] Finally, we’ve got something I got for myself from Kickstarter.
[2:01] An OpenCV AI kit.
[2:04] I’ve got the spatial AI camera module.
[2:07] I’m gonna have to definitely think of something

[2:08] good to do with this as I need to justify actually getting it.
[2:12] I think there’s definitely a desire for more audio projects.
[2:15] Someone’s dropping heavy hints in that direction!
[2:18] And i think we’ve got a bit more AI and computer vision coming as well.
[2:22] Let me know what you’d like to see in the comments.
[2:24] I can’t guarantee anything but I do read every comment

[2:28] Thanks for watching and I’ll see you in the next video.
