"A home for dreamers"
An educational benchtop trainer for secondary and college students to construct AND, OR, NOT, NAND, and XOR truth tables with tactile switches and LEDs.
High school ICT students struggle to visualize boolean logic and truth tables when presented solely through dry textbook diagrams.
Build a durable, clear acrylic-paneled trainer housing standard 74HC series ICs with clear schematic silkscreens, input toggle switches, and bright status LEDs.
Incorporates 74HC08 (AND), 74HC32 (OR), 74HC04 (NOT), 74HC00 (NAND), and 74HC86 (XOR) with 2mm banana sockets for flexible jumper wire patch connections.
Tested across 45 students in an introductory logic workshop in Rangpur.
100% of participants were able to independently verify de Morgan’s laws and construct a half-adder within a single 45-minute lab session.
Fabricating a version with seven-segment displays and 4-bit binary counter modules.
