Building a Mira inspired robot: Electronics arrived [Part 4.1]

The first batch of electronics arrived. I picked them by best guessing the stuff seen in the video from ‘Tested’. I decided to go with the SG90 servos as they are dirt cheap compared to the digital metal gear servos. The only problem so far is that I don’t have any clue how to code the stuff the robot is supposed to do but time will tell. I sense it.

Part Amount Price (total)
Teensy 3.2 1 22,50 €
NeoPixel (Pack of 5) 5 5,35 €
Micro OLED breakout 2 32,40 €
Speaker – 8Ohm, 0.5 Watt 1 1,50€
Amplifier (lingered in the pit for some time) 5 ~3,00€
Total 64,75€

The Rpi 2b+ I have laying around, aswell as the servos. A li-ion battery is floating somewhere as far as I can remember. Oh and I still need a Raspberry Pi Spy Camera. The advantage over the the standard go-to camera is the much smaller pcb and a smaller ribbon cable. This will add another ~30€ to the bot. Also, if I decide to go for the PowerHD servos, they would add 45€ to the pot. This is escalating quickly. Again.
