A portable pocket Tetris project using ATTiny85 and SSD1306 based OLED screen by dombeef.
Pocket Tetris project
This project originally was meant as a fathers day gift for my tetris-loving father, and I felt like it should be available for others if they want to make a pretty small tetris clone. This was the smallest I could make it with a big enough battery and a thick durable 3d printed housing.
I modified tetris code created by Andy Jackson to be used with 3 buttons, since his original code was made for the AttinyArcade platform that has 2 buttons.
In her new Instructables, BECKY STERN illustrates how to add a voice control feature to an vintage lamp using ESP8266 and Amazon Echo/Alexa.
Voice-controlled smart lamp
To control the AC portion of the circuit, I’m using a Power Relay FeatherWing– just interrupt the hot lamp wire and plug the stripped ends into the Normally Open and Common screw terminals. Remember, if you don’t know AC, find someone who does to supervise. My lamp had a switch along the cord, so I just removed it and used the wire that the switch had been controlling.
Here is a bluetooth enabled Arduino garbage monitoring device that indicates the level of the trash in the bin alerting everyone, with the use of a simple mobile app. This small home improvement has lead to a more efficient system.

RyanM415 built an Teensy 3.6 powered car display using an on-board diagnostics (OBD-II) adapter from Freematics and a 7″ TFT LCD from Adafruit. The display has two pages: one shows off when the car is in drive and the other for when it is in reverse gear. During driving mode, it displays the RPM, MPH, engine load percentage, battery voltage, cabin temperature, and engine coolant temperature. And in reverse mode, the Arduino IDE compatible Teensy 3.6 reads an animated bitmap image of the car and displays it along with the readings from the backup sensors.

This DIY Ultrasound Imaging development kit is kelu124‘s entry to Hackaday 2017 prize and is equipped for imaging, based on two ad-hoc ultrasound boards, a Raspberry, a custom ADC, and a motherboard.
DIY ultrasound imaging system development kit
This HSDK has for objective to:
– consolidate existing hardware research;
– simplify and lower the cost of the kit;
– permits benchmarking of ultrasound systems;
– introduce a simple API to control hardware;
– have a server which provides both raw ultrasound and data standard DICOM files;
– have a kit that can be used for pedagogical and academic purposes – not to mention people who want to understand ultrasound!
