If you have a simple Arduino project that uses only a few pins, you might be able to shrink it down to a single 8-pin ATtiny chip. How-To: Shrinkify Your Arduino Projects video and How-To: Shrinkify Your Arduino Projects article shows you how. The best part is you can use the same Arduino code and development environment that you’re already used to.
The ideas presented on video and article are based on a tutorial from MIT Media Lab’s High-Low Tech Group that shows how you how to program an ATtiny45 or ATtiny85 microcontroller using the Arduino software and hardware. The ATtiny45 and ATtiny85 are small (8-leg), cheap ($2-3) microcontrollers that are convenient for running simple programs.

Thank you for your tip. For some reason your link to Indiegogo did not work
Here is one link to that ISP shield project

Gimmick on Barebones Arduino 16MHz
https://www.hackster.io/rayburne/gimmick-on-barebones-arduino-16mhz-861099
Barebones ATmega328P-PU with tunable crystal load capacitors and it is all a gimmick!
The 8MHz version conserves power, is Arduino IDE friendly, and is as cheap as the raw Atmel chip.
But what if you need a 16MHz Crystal Stabilized barebones?
Silly me … there must be a thousand projects out on the Internet about building your own Arduino from bare parts.
Two capacitors formed by the tape and common ground plane will provides our two load capacitors for the 16 MHz crystal.

Let’s Shrink Arduino Projects, Robotics and Automation You all did with Arduino UNO. Now There is Shrinkified Version Here!
Let’s Shrink Arduino Projects, Robotics and Automation You all did with Arduino UNO. Now There is Shrinkified Version, Fully Reliable, Tested and Open Source which allows full 8K Memory. Afterall Every Byte is Necessary. Presented Here is the Working of BABYDUINO Board. The Board needs Arduino or USB to TTL Programmer or Bootloader to Program It. However it is extremely Easy. It is Compatible with Arduino IDE.
