Adafruit TPL5111 Reset Enable Timer Breakout
Enable and disable your projects on a timer like a boss
by lady ada
The Adafruit TPL5111 Reset Enable Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of enabling & disabling your electronics using a built in timer that can vary from once-every 100ms up to once every two hours. Basically, the TPL will set an enable pin high periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely disable the project by setting the enable pin low

Pi Hole Ad Blocker with Pi Zero W
Zap away ads using an ad-blocking custom DNS mini server
by lady ada
This project will turn your Raspberry Pi Zero W into a ad-blocking local DNS server with Pi Hole. When it is asked for the IP address of ads.adserver.com (for example) it will return nothing! So you will never even connect to the ad server and get the ad. Your connection will be faster, less data, and no intrusive ads. It works great on computers, tablets, phones, etc. Even if you cannot run an ad-blocker plugin on your phone or tablet, this will work and ad-blocker-detectors can't tell you're running it.

Motion-Activated Solder Fume Extractor With Lamp
Removes those pesky fumes whenever you reach for the iron
by Jan Goolsbey
A different take on the beginning maker's second project (a clock being the first, of course). We added a motion detector to activate the fan when you're soldering and a USB reading light to eliminate the shadows. The unit employs a USB-rechargeable lithium-polymer battery and provides a separate USB port for the lamp. This solder fume extractor fits into an off-the-shelf enclosure; 3D printing isn't required. Drilling and cutting the enclosure requires some intermediate fabrication skills, but a layout and drilling template is provided to make it easier to prepare the plastic case.

Adafruit Metro Mini
Slim all-in-one Metro that's breadboard friendly
by lady ada
We sure love the ATmega328 here at Adafruit, and we use them a lot for our own projects. The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. METRO Mini is the culmination of years of playing with AVRs: we wanted to make a tiny, breadboard-friendly development board that is easy to use and is hacker friendly. Metro Mini can be programmed with the Arduino IDE (select 'UNO' in the boards dropdown)

Adafruit PiTFT - 2.8" Touchscreen Display for Raspberry Pi
Add a compact 320x240 resolution screen to the top of your Pi
by lady ada
Is this not the cutest little display for the Raspberry Pi? It features a 2.8" display with 320x240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc.

NES Cart RetroPie Game Console
All-in-one game emulator/controller built inside a NES cartridge using Joy Bonnet and Raspberry Pi Zero!
by John Park
The Pi Zero is a great machine, capable of running RetroPie to manage old school game emulation. The Joy Bonnet is a very simple, plug-and-play way to add just the right controls. But you need a case, so embed it in an old cartridge for style and the ergonomics of a better grip!

I2C addresses!
I2C addresses from 0x00 to 0x7F (inclusive)
by lady ada
I2C is incredibly popular because it uses only 2 wires, and like we said, multiple devices can share those wires, making it a great way to connect tons of sensors, drivers, expanders, without using all the microcontroller pins. The only bad news about I2C is that each I2C device must have a unique address - and the addresses only range from 0 to 127 (aka 0 to 0x7F hex). Since we deal with so many I2C devices we thought it would be handy to have a table with all the most common sensors and modules we encounter, and their I2C address!
