I was hacking in the lab quite late one night - soldering pins and debugging the bytes - When suddenly a bang exploded with sparks, and a figure emerged from the hazy dark!
(It wore a mask) It wore a monster mask!
(The monster mask) Its eyes were LCD glass
(It wore a mask) It had some chips on the back
(The monster mask) And a sweet solder mask
This Halloween, you will be the spookiest in town thanks to ADABOX 13! Cat eyes, or monster peepers...The MONSTER M4SK board included in this BOX can be customized with different eyeball and sound effects to bring your costume or cosplay to life. You can wear the M4SK as a set of goggles, or break it apart to have two independent eyes. Pair it with one of the blank masks included for you to decorate, or perhaps outfit a ghost, skeleton or pumpkin decoration!
Adafruit MONSTER M4SK
Peep dis! Have you always wanted to have another pair of eyes on the back of your head? Or outfit your costume with big beautiful orbs? The MONSTER M4SK is like the Hallowing but twice as good, with two gorgeous 240x240 pixel IPS TFT displays, driven by a 120MHZ Cortex M4 processor that can pump out those pixels super fast.
This unique design has the eyes at the same pupil-distance as a human (~63mm) but is designed so that the nose section can be broken apart with pliers/cutters and then wired together with a 9-pin JST SH cable up to 100mm long so the eyes can be re-positioned or freely attached.
We wanted to make audio-effects easier so in addition to a class D audio amp, there's also a stereo headphone jack that is connected to the two DACs on the chip. Use it when you want an externally sound amplifier box for big effects. For small portable effects, the built-in amp can drive 8 ohm speakers up to 1 Watt.
On each side are JST-PH plugs for connecting external devices. The 3-pin JSTs connect to analog/timer pins on the SAMD51, so you can use them for sensors or GPIO devices. The 4-pin JST connector connects to the I2C port and you can fit Grove connectors in it for additional hardware support. For the PDM mic port, you can use this cable to wire to a PDM mic.
There's also plenty of sensors built in - light sensor, 3 tactile buttons, and a capacitive touch pad on the nose.
This is by far the cutest, creepiest and most incredible development board we've made so far! Gaze upon these features:
- ATSAMD51G19 Cortex M4 microcontroller running at 120MHz with 512KB Flash, 192KB RAM
- 8 MB QSPI flash for storing graphics and sound effects
- Two 240x240 IPS TFT displays each on their own SPI bus
- Beautiful silkscreen with a boop-able nose that is a capacitive touch pad
- Lipoly battery charge circuit for portable use
- Stereo headphone jack out, for sound effects via an amplifier
- Mono speaker driver for smaller 8 ohm 1W speakers
- One 4 pin STEMMA JST connector for I2C connection (also Grove compatible)
- Two 3 pin STEMMA JST connectors with digital/analog/PWM for servos, sensors, etc
- One 4 pin JST SH port for connecting an optional PDM microphone
- Backlight controls
- Three tactile buttons
- Light sensor
- On/Off Switch and reset button
And as you can expect, we've got some great new eyeball code, which does 2 eyes with user-configurable graphics. Right now our code support is only for Arduino - CircuitPython isn't quite fast enough to do the 3D animation techniques we use to draw the eyeballs.
2 x Plastic Lenses
When placed over the displays, these will both protect the TFT and enhance the eye effect. These are plastic lenses, with brilliant clarity and a nice convexity (is that a word?)
Acrylic Cut Lens Holders + Hardware Kit
These cut pieces, when attached with the included nylon screws, hold the plastic lenses in place.
See the “Lens Holders” page in the “Introducing MONSTER M4SK” section for guidance on getting these to fit.
Elastic Band + Tri-glides
The elastic goes through the M4SK lens holder slots so you can more easily wear it on your head.
Lithium Polymer Battery
The M4SK can be powered with this battery for portable use, and will recharge it automatically when plugged into USB. Battery will last about 3 hours with both screens on full brightness
Plug this 8 ohm 1W speaker into the M4SK to create sound effects! We particularly like this speaker as it is small and comes with nice skinny wires with a connector on the end. It has a handy "Molex PicoBlade" 1.25mm pitch 2-pin cable, which makes plugging into the M4SK easy.
Microphone + 4 Wire Cable
This PDM microphone can plug into the M4SK for audio input. The STEMMA QT / Qwiic cable makes it easy to connect.
9 Wire Cable
If you like, you can break the nose-bridge from the M4SK and then use this extension cable to keep the eyes electrically connected. Perfect for that beak-faced bird costume!
Use these with the M4SK or on their own. They can even be decorated, if you like, with paints and glitter by using the included kit!
