cup. The ESP8266 was programmed to send UDP packets to [CNLohr's] laptop. When
the laptop responded back, the ESP8266 turned on the LEDs, lighting up the
cup. The cup's response to signal strength was very quick – about a second.

[CNLohr] took the WiFi Cup around the house. He was surprised to detect the

[Ray] has created RFToy, a simple gadget to
aid in setting up wireless systems with a variety of common radio modules.
RFToy is an open source microcontroller board running on an ATmega328. While
RFToy is Arduino code compatible, [Ray] chose to ditch the familiar Arduino
shield layout for one that makes it easier to install RF modules, and is more
handheld friendly.

[RFToy] includes headers for the popular nRF24L01 2.4 GHz transceiver, as well
as 433/315 transmitters and receivers found in many low-cost wireless
electronic devices. The 128×64 pixel OLED screen and 3 button interface make
it easy to … Read the rest
