The Altronics Z6387 is a WiFi and Bluetooth-enabled 2MP (two-megapixel) digital camera utilising the ESP32-S3 microcontroller. It can be interfaced with another microcontroller or used as a standalone device. by Tim Blythman
This handy little tool uses an inexpensive Raspberry Pi Pico microcontroller board and not much else to generate and analyse audio signals. It has oscilloscope and spectrum modes and can run a sweep to plot a frequency response or perform harmonic analysis to check signal quality. It fits in the palm of your hand, is portable and battery powered. by Tim Blythman
This simple and low-cost circuit can produce a voltage around twice its DC input, or instead, a negative voltage of similar magnitude to the input. That can be handy in many situations, such as running op amps from a battery or DC supply, driving Mosfet gates, or providing a wider output range for adjustable regulators. by John Clarke
This small, low-cost adaptor lets you program most newer PIC microcontrollers out-of-circuit. It works in conjunction with a PICkit or SNAP in-circuit programmer and provides five different modes to suit a range of chips from eight to 40 pins. It can even be used with SMD chips in SOIC, SSOP or TSSOP packages. by Nicholas Vinen
What was the genesis of Silicon Chip magazine? Leo Simpson, the founder of Silicon Chip, tells how the seeds were sown several years before, in 1984, when he was editor of “Electronics Australia” magazine. by Leo Simpson
