2 8-bit computer update
Entry point to Ben Eater's breadboard computer series, linked when someone asks how a CPU, registers or clock cycles work at the hardware level.
3 Making logic gates from transistors
Ben Eater builds basic logic gates from transistors, resistors and LEDs on a breadboard; beginners often follow it, then ask how the XOR circuit works.
4 Using an EEPROM to replace combinational logic
Ben Eater programs a parallel EEPROM by hand and uses it as a lookup table to drive a seven-segment display in place of discrete logic.
5 Astable 555 timer - 8-bit computer clock - part 1
Ben Eater explains the inner workings of the 555 timer and builds an adjustable astable clock for his 8-bit computer; popular with beginners following along on breadboards.
6 Designing a 7-segment hex decoder
Ben Eater builds the logic that turns a 4-bit value into seven-segment digits using plain gates, praised as a clear introduction to combinational design.
7 The world's worst video card?
First part of Ben Eater's series building a VGA video card from logic chips on a breadboard; recommended for understanding VGA timing and the effort involved.
8 How does a USB keyboard work?
Ben Eater captures a USB keyboard's signals on an oscilloscope and works through the protocol manually, recommended to anyone trying to understand USB at wire level.
9 “Hello, world” from scratch on a 6502 - Part 1
Ben Eater starts building a 6502 computer on breadboards, single-stepping the clock to watch the bus; a frequent starting point for people building their own.
10 JK flip-flop racing
Ben Eater builds a JK flip-flop and shows why it works only intermittently because of a race condition, cited to settle questions about his earlier latch schematic.
11 How a transistor works
Ben Eater's explanation of how a bipolar transistor works, repeatedly offered as a very helpful way to grasp the basics.
12 8-bit CPU control logic: Part 1
First of three parts on control logic for Ben Eater's 8-bit computer, showing how control lines and microcode steps execute an instruction over several clock cycles.
13 Reliable data transmission
Ben Eater video on sending data reliably from one Arduino to another, which a couple of viewers praise as an excellent and detailed explanation.
14 Programming my 8-bit breadboard computer
Warmly recommended for learning how a processor works from the ground up by building a simple computer from scratch and seeing code run on real hardware.
Hidden gem15 Why build an entire computer on breadboards?
Ben Eater's breadboard work, linked mainly for the section comparing good and cheap solderless breadboards and for tidy wiring technique.
16 Testing our computer's registers - 8-bit register - Part 5
Part of Ben Eater's breadboard 8-bit computer, testing the register module with LEDs on the bus; often cited when builders hit marginal logic levels.
17 Analyzing actual Ethernet encoding | Networking tutorial (4 of 13)
Ben Eater probes a 10BASE-T link with an oscilloscope and decodes the Manchester-encoded bits by hand; part of his networking series and a common starting point for line-coding questions.
18 Monostable 555 timer - 8-bit computer clock - part 2
An episode from an 8-bit computer build series, explaining how a 555 timer provides the clock and handles debouncing, praised for laying out the theory clearly.
19 Build an 8-bit decimal display for our 8-bit computer
Used as a worked example of multiplexing several seven segment displays from one EEPROM, with a 555 timer and JK flip-flops providing the count.
20 Build an Arduino EEPROM programmer
Ben Eater builds an Arduino Nano programmer for AT28C parallel EEPROMs, using shift registers for the address lines; people build it for their own projects.
21 Bistable 555 - 8-bit computer clock - part 3
One of a set of clock module videos using 555 timers for a home built CPU, covering the bistable switch that selects between the oscillator and a pushbutton.
22 Designing and building a 1-bit register - 8 bit register - Part 3
Part of Ben Eater's 8 bit computer series, this one builds a register from D flip flops and is cited in questions about registers and RAM.
23 SR latch
Ben Eater builds an SR latch from NOR gates on a breadboard and shows how feedback holds a state; people copy it when learning sequential logic.
24 JK flip-flop
Ben Eater builds a JK flip-flop and uses an RC edge detector to shorten the clock pulse; cited in questions about that capacitor and master-slave designs.
