The STEM-X1 is a pocket size 4-bit adder / subtractor for educators, computing enthusiasts and curious makers. It provides a hands-on way to learn the basics of binary arithmetic through digital electronics.
STEM-X1: Explore binary arithmetic the hands-on way
The STEM-X1 is your very own DIY pocket 4-bit adder / subtractor, which enables you to really see and understand how binary arith-matic works through an array of ultra-bright LEDs and 74 series ICs. It is a fun and rewarding soldering activity for educators, computing enthusiasts and makers. The X1 also supports STEM learning by blending core computer science concepts with a real electronics application, so you can connect theory and practice in an intuitive and hands-on way!
The DIY kit comes as a complete collection of through-hole components, a beautifully engineered X1 PCB, and an easy to follow assembly guide to help you build and operate a fully working 4-bit adder and subtractor.
For educators:
The X1 is the perfect tool for teaching computing concepts in a fun, memorable and hands-on way. It enables you to bring abstract theory to life using real hardware - reinforcing classroom learning.
For computing enthusiasts:
Rediscover the basics of binary arithmetic in a memorable and enjoyable way. The X1 is the perfect kit to bring back to life the joy of 7400 series ICs and those fundamental basics of binary arithmetic - such as two's complement!
For makers:
Looking for a rewarding weekend electronics project or STEM activity without spending a fortune? ARITH-MATIC kits are a perfect learning activity for curious individuals, family or friends and an ideal project for practicing soldering skills.
This is the best and most intuitive way to learn about binary addition and subtraction.
