ESP32 based IoT 4WD robot platform

Wifi/BLE enabled 4WD robot platform

Stefan designed an IoT enabled, compact and modular, 4-wheel drive robot platform powered by ESP32. It is controllable over WiFi and BLE. As controller board an ESP32 Thing board is used this can be programmed by the Arduino IDE and allows even OTA updates. It isn’t the cheapest but offers a compact size and includes a LiPo charging capability (Which I managed to blow off by attaching the LiPo in reverse polarity L). As sensors the robot contain a BN0 055 absolute orientation sensor, a rotation encoder for both sides, four proximity sensors in the bottom (line follower, gap detection) and

Arduino cellphone signal booster

Arduino cellphone signal booster

Tecwyn Twmffat built an Arduino-based Cell Phone 4G Signal Booster. Living on an island in the middle of nowhere, mobile/cell phone reception can be rather intermittent and it seems that there is currently no reliable open source gadget that could help me solve this problem on my kind of budget. I do have the option of using ‘cable phone’ but being of a general ‘Pirate’ disposition I thought it would be a better idea to do all my phone calls, emails and data transactions by cell phone and save a whole bunch of dollars by not having to pay for land

ESP8266 Twitter Client

Twitter client

Andrei Mehiläinen shared his ESP8266-based Twitter Client project that is built using a 256×64 OLED (SSD1322 based) display. It connects directly to Twitter, so no third-party proxy services are used. The device connects to user stream and displays all the incoming tweets for that user. This basically means the same tweets the user would see on her Twitter main page. Additionally, a track paramter can be set to include tweets containing specified keywords. The tweet currently shown on the display can be retweeted, liked and shared by sending link to it in direct message. This way user can easily access shared

ESP8266 Space Invaders

Tobozo Tagada incorporated the uArcade Space Invaders game (Arduino playform) to ESP8266 with a nice buckle box enclosure. It uses a WeMOS D1 Mini Pro board for ESP8266 and a SH1103 based 1.3inch OLED screen for display. The original uArcade code can be found here.
