I think it's time for another mailbag
So let's see what we've got?
The first item is this extremely well-wrapped box so let's try and get into this
So it looks like we have a
power supply
I think I know what this is
So, this is an extremely high-quality
Laser Galvo scanner.
It looks pretty amazing
So we can use this as an upgrade to the laser-driven asteroids
it does use quite a funky connector to drive it
I did find a driver for this online that uses a Teensy and I think one of these parcels...
yep, so I've ordered a teensy because I found some software online that will drive this pretty nice laser galvo scanner
and the software runs on a teensy so I'll be trying that out later
so that's pretty exciting I'll put this somewhere safe because it's pretty fragile
let's put that
over there along with the power supply and cables
so what's next?
another box from China
so when I was doing the magic mirror project
I thought I had broken my driver board
so I ordered another one thinking I would need a replacement
and then found that the driver board was completely fine
so this is another driver board for an iPad LCD
and I think since I knew I had ordered an extra one, I found a very cheap iPad 1 display on eBay
I think this cost 12 pounds
so I think that's what this should be
it's very nicely wrapped let's have a look at what's in here
certainly no shortage of bubble wrap now
so I have another iPad 1 LCD
to go with my spare driver
so I'll have to think of another project to do with an LCD
so I'll add that to the list of things to use in a project
so that's quite good
let's wrap this backup
and I think to go with that
I've ordered
another RaspberryPi Zero
so maybe I'll just make another magic mirror that could be a fun project
so what else have we got?
I've already unwrapped these
but this is a pretty interesting microphone: the IA611
so this has built-in wake word detection
so if we have a look at um let's have a look
so there's the actual microphone and the microphone has a built-in DSP
and it can do wake word detection
I'll need to work out how to actually interface to this
and um bizarrely I've somehow ended up with two of these
so two microphones with wake-word detection which I'm not sure how to use yet
so that's probably a project in itself just understanding that so let's put that to one side
so what's next we have some um screw headers
now I think these are to go with some PCBs
yes we've got a box from PCBWay
so let's have a look at what we've got in here
slightly bigger box than usual
okay ah nice
so these are some little amplifier boards
I've been using the Adafruit amplifier boards the MAX98357 and
I thought it would be nice to uh have two of them so we can do stereo sound
and these little um these little screw terminals hopefully, if I've ordered the right ones, should fit
right about
err, which way round does this go
right about here
so yes, I think that will fit nicely
1 speaker
two speakers
and these should be pin-compatible with the Adafruit boards
so hopefully, I'll be able to plug this straight into my audio PCBs
and I think if I'm lucky
I should have all these
stereo amplifier boards
I think I ordered ten of these may be?
one two three four five six
and then I've also got some new audio boards that we're plugging these into
let's see if we can get into here
so these are version two of my my audio boards
they just make it slightly easier to wire everything together
so you can just plug the microphone and the amplifier
and a TinyPico
and I've broken out the header pins now to make this slightly easier to use
these little amplifiers will plug straight into this board
and we'll have a stereo output which should be pretty cool
so that's uh thanks PCBWay. PCBs and SMT assembled boards
That's brilliant I'll try these out in a later video
and we'll see if I've done the PCBs correct
so let's try that out in another video
and then the last thing I've got
I've no idea what this is
must-have ordered something and forgotten
so let's have a look
Let's open this up
now that's it's a LillyGo
It's a LillyGo something
let's see what uh what LillyGo we've got
ah cool!
so this is a paper display from LillyGo
so I wonder um yeah pretty cool
I have to find a good use for this
I think it's showing something at the moment
yeah brilliant
so any suggestions on what to do with this would be much appreciated
we've got some buttons, let's see, buttons don't do anything yet
I'm sure we'll uh we'll work something out
well that's pretty cool so a paper display
what size this is with my ruler
so it's pretty that's pretty big to be honest
seven by four
so brilliant so that's gonna be uh should be a fun project to do something with this
looks pretty full-featured
so we've got an sd card slot um yeah pretty cool
so yeah that's a few projects to get on with
I think
we'll probably do these PCBs fairly soon
so these are just some blank ones
so if I feel like trying to solder some of these I'll give that a go
but I think I'll stick to the PCB assembled ones
so let's have quick look at these again
the bags are tough!
so let's see if I can get that in focus
so that's pretty cool
so good job PCBWay
so I think that's probably it for the mailbag I think that's everything
we'll have a look at this um these uh microphones as well let's see if we can focus
so I need to work out how to connect these I'll work that out slowly over time um it should be fun
I've got another other display to do a project with so I'll have a look at doing something with another
iPad display maybe I'll try and
make a Pi-Zero laptop or something or um or maybe actually try and connect it up to my ESP32
I've seen a few people doing VGA projects with the ESP32 so that might be quite a fun project
but let me know what you think
I'll see you in the next video
