This Hands-On Electronics eBook from 3D-LABS is written for engineers and students who want a clear, practical reference they can apply immediately.
Hands-On Electronics — From LED to PCB covers practical electronics from LED circuits through signal conditioning, digital logic, microcontroller interfacing, and PCB design using KiCad 7, with production-ready PCB guidelines.
What electronics topics are covered?
(1) LED resistor R=(V_supply-V_f)/I_LED, (2) op-amp non-inverting gain Vout=Vin*(1+R2/R1), (3) 555 timer astable f=1.44/((R1+2R2)*C), (4) Arduino sensor interfacing, (5) KiCad 7 schematic and PCB layout, (6) PCB design rules per IPC-2221B (trace width, clearance, via size).
What PCB design standards are used?
IPC-2221B: minimum trace width W = I/(k*delta-T^0.44*t^0.725), k=0.048 external traces. Clearance: 0.13 mm for up to 15 V, 0.25 mm for up to 30 V. Silkscreen height minimum 1.0 mm per IPC-7351B.
What sensor signal conditioning is covered?
INA128 instrumentation amp for sensor signals: G=1+50k/R_G. Wheatstone bridge: delta-V=Vs*delta-R/(4R0). 4-20 mA: 250-Ohm sense -> 1-5 V. RC low-pass filter: fc=1/(2*pi*R*C).
