Remote Control and Thermometer for Cappuccino Machine

My cappuccino machine takes about five minutes to warm up, and I wanted to turn it on remotely over wifi when I wake up so that when I enter the kitchen in the morning I wouldn't have to wait for it to warm up. I also wanted to be able to tell whether or not it was warmed up, so I added a thermometer and a LED ring to display the temperature.

Parts List:

1 X ESP8266 ... ds=esp8266

Dallas temperature sensor ... V2RPBDKQ77

Adafruit Neopixel LED ring ... pixel+ring

PWM servo, a Hitec perhaps ... itec+servo

ESP8266 Code

The code is on my github:

Atticbot is a remote control vehicle thing that I designed to remotely crawl around my attic and inspect the bats that had moved in. It's basically just a couple of continuous-rotation servos attached to a yardstick frame, a battery, an RC receiver, a video transmitter, and a camera.

Parts List:

2 x continuous rotation servos

2 x yardsticks for frame

1 x RC receiver - FrSky somethingorother
1 x RC transmitter - Turnigy 9XR-Pro perhaps
1 x 5.8ghz Video transmitter+camera
1 x 5.8ghz Video receiver/display

I've really skimped on details on this parts list. Email me if you have questions.

Object Avoiding Robot


This 4wd robot navigates about using two SR04 ultrasonic distance sensors. One sensor points down to detect stairs/cliffs, and the other points forward and rotates left/center/right using a micro servo.


4 x continuous rotation servos (for drive wheels)

4 x wheels - must misc wheels I rounded up from toys, screwed onto the servo horns.

1 x micro servo to rotate forward-facing SR04

2 x SR04 ultrasonic sensors\

1 x Arduino

misc wood, hot glue gun, machine screws


The Arduino code for this robot can be found here:

RC Robot with Headtracking and FPV Video


This is a 2 wheel drive robot that uses car wiper motors for its drive motors, sends video to FPV goggles, and receives headtracking data to move the camera accordingly on a two-servo gimbal.


2 x DC wiper motors (modified to remove common ground)
1 x RC Receiver - frsky
1 x Arduino Uno for robot
1 x Arduino Leonardo for head tracker
1 x gyro/accelerometer
1 x Motor controller (dual H bridge was used)


Headtracker Arduino code (requires 32U4 Arduino):

RC Robot code (works on just about any Arduino):
