DESIGN CONSIDERATIONS FOR TRANSFERRING A BREADBOARD PROTOTYPE TO CUSTOM PCB

In Sayanee’s Basu’s video, we can look at the design considerations in the process of taking a breadboard prototype to a custom PCB, from the microcontroller to the various subsystems, to the power, the bootloader, and even how to deal with faulty components. A breadboard can be useful for educational purposes, art projects, and even small …

FREE ELEKTOR CIRCUIT – ACOUSTIC IR REMOTE CONTROL TESTER

In this circuit we use the output signal from a standard IR receiver (IC1 in the schematic of Figure 1) to drive a miniature loudspeaker. The IR receiver from Vishay used here is available for various frequencies ranging from 30 to 56 kHz. A large number of IR remote controls operate according to the so-called RC5 protocol that …

THINKING ABOUT CREATING A RASPBERRY PI REPLACEMENT?

If you’ve ever wanted to try your hand at creating a Raspberry Pi-like board for yourself, you should check out [Jay Carlson’s] review of 10 different Linux-capable SoCs. Back in the 1960s, a computer was multiple refrigerator-sized boxes with thousands of interconnections and building one from scratch was only a dream for most people. Then ICs …
