Hello 3D Printed Dolly

Hello 3D Printed Dolly

[Ivan] likes to take time lapse videos. Using his 3D printer and a stepper motor he fashioned a rig that allows him to control the camera moving any direction on a smooth floor. The dolly has a tripod-compatible mounting plate and scooter wheels. An Arduino runs the thing and a […]

Raspberry Pi, Send Me a Letter

Raspberry Pi, Send Me a Letter

The abundance of small networked boards running Linux — like the Raspberry Pi — is a boon for developers. It is easy enough to put a small cheap computer on the network. The fact that Linux has a lot of software is a double-edged sword. On the one hand, it […]

How to Get Started with the ESP32

How to Get Started with the ESP32

ESP32 is the hottest new wireless chip out there, offering both WiFi and Bluetooth Low Energy radios rolled up with a dual-core 32-bit processor and packed with peripherals of every kind. We got some review sample dev boards, Adafruit and Seeed Studio had them in stock for a while, and […]

Oculus Pi

Oculus Pi

  [WayneKeenan] wrote a proof-of-concept virtual reality system that used a Raspberry Pi and an Oculus Rift. It was about a thousand lines of Python and with a battery pack it was even portable. The problem was that the Pi was struggling to create the 3D views. [Wayne] recently revisited […]

Arduino Vs. Arduino: Arduino Won

Arduino Vs. Arduino: Arduino Won

  For the last two years, Arduino LLC (the arduino.cc, Massimo one) and Arduino SRL (the arduino.org, Musto one) have been locked in battle over the ownership of the Arduino trademark. That fight is finally over. Announced at the New York Maker Faire today, “Arduino” will now go to Arduino […]

Cellular Automata Explorer

Cellular Automata Explorer

  Well all know cellular automata from Conway’s Game of Life which simulates cellular evolution using rules based on the state of all eight adjacent cells. [Gavin] has been having fun playing with elementary cellular automata in his spare time. Unlike Conway’s Game, elementary automata uses just the left and […]
