Let's Build a Simple Breadboard Computer
Things we can learn from the video
Press to jump
- 1:45Transistors and AND, OR and NOT gates are explained through animations and an LED demonstration board.
- 3:29A 555 timer supplies the clock signal, while a potentiometer controls its speed.
- 5:39An apartment-building analogy explains RAM, followed by Jump, Halt and Reset instructions.
- 10:27Working programs turn the breadboard computer into an alarm clock and an 8-bit-style music player.
- 11:51An added binary-adder chip demonstrates addition.
- 12:26Sage makes a custom circuit board and fits the computer into 3D-printed enclosures.
A speaker gives 3DSage's homemade computer something to say. In "Let's Build a Simple Breadboard Computer," the wired-up project becomes an alarm clock and an 8-bit-style music player, turning a lesson in logic into something you can actually hear.
There were no new uploads this week, but that older tutorial remains the channel's most active video, now past 110,000 views. When we last covered the project, the parts list was the starting point. The finished build offers a better reason to settle in: Sage moves from animated logic gates to switches, working programs and a neatly housed circuit board.
"So my goal is to remove the mystery of computers with tactile, hands-on learning," he says. A 3D-printed mechanical counter makes binary counting visible, while an apartment-building analogy helps explain memory. He even addresses the objection that the machine should perform math, adding a binary-adder chip to demonstrate addition.
Across the channel, daily views are running at nearly twice their usual level, although the subscriber total was unchanged over the week. The clear retro music sequencer and homemade game-console build are also drawing views, at a much gentler pace than the breadboard lesson.
Among nearby maker channels, The Lawn Dad had a substantially busier viewing week, while Keith Fenner was quieter. For 3DSage, the useful catch-up is unusually tangible: a computer whose clock, memory and instructions are laid out where you can follow the connections.
