[0:00] it’s time for a mailbag
[0:02] we’ve got a parcel from PCB way
[0:10] let’s see what we’ve got
[0:15] it’s my ever so tiny
[0:18] esp32 breakout boards
[0:28] I’ll do some close-ups of these later
[0:30] let’s try plugging one in and see what
[0:32] happens now there’s currently no esp32
[0:35] on these so I’m not sure what will
[0:37] happen but we do see a little LED
[0:40] so what will happen on the top of these
[0:43] we’ll have a esp32 plugged in
[0:46] so I’ve had some of these delivered so I
[0:49] have a bunch of esp32s
[0:52] so what I’m going to try and do is
[0:54] remake one of these tiny TVs
[0:57] so this is a tiny TV
[1:01] and it’s pretty cool so I thought it’d
[1:03] be quite fun to try and make our own
[1:05] version of this so I’ve made up this
[1:07] very simple
[1:08] esp32 board we’ll solder an esp32 onto
[1:12] the top here so one of these modules
[1:15] well let’s stick on the top there
[1:18] and um I’ve also got
[1:20] some little speakers so I’ve got these
[1:24] tiny speakers that we can um slow it on
[1:27] there’s two pads here for a speaker
[1:30] and I got these very nice little
[1:31] displays
[1:33] so these have come as well
[1:36] so our TV will be slightly bigger than
[1:39] theirs but it should still be pretty
[1:40] nice so I’ll do some close-up shots over
[1:43] there of this board later
[1:45] um for the end of the video and we can
[1:47] have a look everything seems seems okay
[1:50] nothing is getting warm so that’s quite
[1:52] promising so also from PCB weight
[1:59] we should have some nice adapter boards
[2:02] for these
[2:03] so
[2:05] I’ll be able to solder one of my
[2:08] breakout boards onto this and plug it
[2:11] into some breadboard so this should
[2:15] slot on like that
[2:18] and then we’ll have a nice um breakout
[2:20] board for testing these in a slightly
[2:22] easier way so that should be good fun as
[2:25] well so I’ve also ordered an Arduino
[2:28] Nano esp32 so this is an S3 based um
[2:33] device
[2:34] so this should be quite interesting to
[2:36] play with it’s interesting is actually
[2:38] using a different kind of module from
[2:40] the ones we’re used to obviously it’s
[2:42] quite a tiny module so this should be
[2:45] quite interesting I’ll be interested to
[2:46] see how this Stacks up against things
[2:48] like the tiny Pico from unexpected maker
[2:51] which we use a lot in our projects so
[2:54] stay tuned for a detailed video on the
[2:57] Arduino Nano esp32
[3:00] I’ve also received one of these mini
[3:02] wear electronic loads so I’ve been using
[3:08] this electronic load for quite a while
[3:11] but I thought it’d be nice to invest in
[3:13] something slightly more sophisticated
[3:15] so
[3:17] this will be very useful for future
[3:19] projects let’s open it up and have a
[3:22] quick look I do like the uh
[3:25] mini wear products they always look
[3:27] pretty amazing
[3:30] all right let’s get this out of the box
[3:37] so that’s kind of neat so
[3:41] very nice compact little um electronic
[3:45] load now someone recently gave me an ATX
[3:48] power supply so I ordered a
[3:51] ATX power adapter I guess you could
[3:53] never have too many USB ports that’s
[3:56] going to be quite handy
[3:58] um I’ve got this older one but uh this
[4:00] one looks slightly better I’ve also been
[4:02] playing with building my own power bank
[4:03] so I’ve got this nice board here but um
[4:07] we’ll try out so we’ll use the
[4:09] electronic load to test these out in a
[4:12] future project
[4:13] so I’ve also ordered a couple of the
[4:15] cheap yellow displays that Brian Locke’s
[4:18] been talking about a lot
[4:20] um these are pretty cool so I can power
[4:23] one of these up
[4:25] they come with a small demo
[4:29] um
[4:30] so everything
[4:31] try this out it works it works
[4:34] surprisingly well and they are
[4:36] very very cheap hence the name cheap
[4:39] yellow display
[4:40] and now I’ve
[4:43] flashed one this one with um an emulator
[4:48] Gallagher so let’s try that
[4:52] should boot up so we’ve got Pac-Man
[4:55] Gallagher Donkey Kong
[4:57] and I think if I push some of these
[5:00] buttons
[5:02] the game should start up so there we go
[5:04] Gallagher running
[5:07] so to go with this
[5:09] we’ve got some
[5:11] some wee nunchucks and I also ordered a
[5:14] little breakout board to make these
[5:16] slightly easier to um to play with so
[5:18] that should be a fun project for the
[5:20] future we’ll do a do a video on the
[5:22] cheap yellow display soon and that would
[5:25] be pretty cool
[5:26] now the other thing I’ve ordered is this
[5:28] RGB bead curtain
[5:31] so this is pretty interesting I saw this
[5:34] on Becky Stones Channel she was doing a
[5:37] DIY version and then realized that there
[5:40] was actually a version on AliExpress
[5:42] that you could buy so this is a bead
[5:45] curtain with RGB addressable LEDs so
[5:49] that’s quite cool
[5:51] um let me find a plug and we can try
[5:54] this out
[5:59] oh we’ve got some flashing lights
[6:02] and we’ve got a remote control so we’ll
[6:05] do a tear down of this and we’ll see
[6:06] just how hackable it actually is and
[6:09] what we can do with it so that should be
[6:11] a fun project
[6:12] we do like an LED project on this
[6:14] channel
[6:15] now another thing I’ve been playing with
[6:17] recently is a Raspberry Pi zero with a
[6:20] display
[6:21] and I’ve been turning this into a into a
[6:24] doom playing machine so let’s power this
[6:26] up so I’ll currently boot into x windows
[6:29] I thought it’d be good to add some sound
[6:31] so I’ve got a couple of uh little
[6:33] speakers here and we need some control
[6:35] as well so I put a little um games
[6:38] controller
[6:40] and we’ll do some wiring up to plug this
[6:42] into the Raspberry Pi which should be
[6:45] booting there we go
[6:48] and it should run chocolate Doom to
[6:52] games
[6:53] chocolate Doom so obviously we need
[6:57] sound so we’ve got some speakers and
[6:59] we’ll use some way of controlling it so
[7:01] we’ve got a little um controller here
[7:04] try plugging it all together and seeing
[7:06] if it works and then the last things I
[7:08] want to play with for another project is
[7:11] building a little air quality meter
[7:16] this little box here
[7:18] there’s a air particle measuring thing
[7:20] so this will detect um particles in the
[7:23] air
[7:24] this is a CO2
[7:27] level meter
[7:29] and this is an air quality metering it’s
[7:32] humidity temperature and other stuff so
[7:36] that will be another fun project to try
[7:38] out
[7:39] it looks like I’ve got a lot of fun
[7:40] projects to try in the future so watch
[7:42] out for the videos coming soon
