RGB LED ‘Analog’ Clock by Nicholas Vinen.
This colourful and unique clock tells the time with a circle of LEDs that lights up in
different colours to represent the hour, minute and second ‘hands’. An optional light
chaser effect has the LEDs racing around each second.

USB Power Adaptor by Nicholas Vinen.
This simple and cheap PCB provides an easy way to add a USB socket to a device
powered by 5V DC. It accepts a Type-C or mini/micro Type-B socket and provides
optional reverse power flow/reverse polarity protection and LED power indication.

SSB Shortwave Receiver, part two by Charles Kosina.
Introduced last month, this new Receiver covers the shortwave band from 3MHz to 30MHz. It is digitally tuned and has a host of useful features like squelch, USB/LSB support, good sensitivity (a -107dBm signal gives 13dB SNR) and fast or slow AGC.

433MHz Digital Receiver Module by Tim Blythman.
Last month, we presented our 433.9MHz LPD433 transmitter module, which performs better than many prebuilt versions. This matching receiver module has several advantages over commercial equivalents too!
