An even cheaper Wi-Fi board


For a few cents more than the ESP12F you get it with a programmer daughter board, a RGB led, a button and a photoresistor.
This is ideal for small robot with networking abilities.
Can be programmed with Arduino IDE as a NodeMCU v1.0 .

An accelerometer/gyro goes onto an Arduino board and transmits the angular motion of the board via bluetooth to a (extremely amateur VR game) I made in Unity for Android phones.
This is a really fun and easy project that can be done in about an hour. On the bottom of the skateboard is an accelerometer/gyro with an Arduino board that … Read more

Curt the Creeper Update: Adding Voice Interactivity and Sound; 4 bar linkage design

Update:
--------------

I spent the past few weeks researching voice interactivity and sound effect playback (mainly through Google search), and designing a 4 bar linkage to figure out what powertrain I need to drive the feet movement.  I thought others might benefit from info about my work so I'm posting it here.  This project will likely move at a fairly slow pace mainly due to current budget constraints.

Stuck with Phoenix hexapod

I'm building a phoenix hexapod with MG996R servos, Arduino and Lynxmotion SSC-32U controller. (At one point I tried using another 32-channel controller, but decided to go with one that's officially suppored by Phoenix code.)

Walks around, lifts lid, blinks; currently random behavior.
