2. Get the Other Parts - KnowScratcher/QuakeCord GitHub Wiki
In this session, we'll introduce how to get the other components for building the QuakeCord.
You can go to a local electronic component store or buy it online.
If you're in Taiwan, use Shopee.
Other choices are also available.
- AliExpress: shipping may take awhile.
- Amazon: A bit more expensive, but fast.
Because I live in Taiwan, so I'll add a TWD column.
| Item | Amount | Price(USD) | Total(USD) | Total(TWD) |
|---|---|---|---|---|
| ESP32 dev module | 1 | 5.34 | 5.34 | 160 |
| MPU6050 (soldered) | 1 | 4.33 | 4.33 | 130 |
| Case (3D print) | 1 | 0.91 | 0.91 | 27 |
| Jump wire (pin - socket) | 5 | 0.19 | 0.19 | 6 |
| Breadboard mini (45x35mm) | 1 | 0.17 | 0.17 | 5 |
| Total | 10.75 | 328 |
The exact model is ESP-WROOM-32 ESP-32S, you'll need the one at least with wifi (bluetooth doesn't matter for this project).
You really want that flat space on the socket side and no antenna sticking out on the other side.
And of course you'll need a USB micro-B cable to upload the program and provide power.
MPU6050 is a sensor containing both accelerometer and gyroscope.
Sometimes it's called GY-521 and it has a ITG/MPU printed on a side of the PCB.
You will 3D print it.
We need 5 jump wires, the length should not be too long, at most 10 cm (or the wire will take up all the space in the case and make it impossible to maintain).
Specifically, you want to find the "Male-Female dupont wire" that is less than 10cm.
We use breadboard mini for this project.
The dimensions are 35*47*8.5mm.
