NE555 timer sparks low-cost voltage-to-frequency converter
by Gyula Dioszegi @ edn.com: In 1971, Signetics—later Philips—introduced the NE555 timer, and manufacturers are still producing more than 1 billion of them a year. By adding a few components to the NE555, you can build a simple voltage-to-frequency converter for less than 50...

JFET Moving Coil (MC) Pre-Preamp Kit
by Mark Houston @ diyaudioprojects.com: I received the Boozhound Labs JFET Moving Coil (MC) Pre-Preamp Kit a while back and I promptly assembled the small circuit board. I'm a sucker for a simple kit and a hot iron. That is where it all stopped. The circuit board remained complete...

WiFi-based Weather Forecast and Clock
by soniktech.com: This project is a stopgap on my way to building a ground-up "Internet of Things" base design around the ESP8266 SoC WiFi solution. I started by taking a few nixie tubes I've had lying around from a past project, and connecting them to a Nixie Power supply I found on...

Attiny45 EMF Sensor
by Khaleel123 @ instructables.com: This sensor is very sensitive and can pick up electrical signals from anything that uses power. It displays the amount of interference it picks up by sequentially lighting 4 led's one after the other. I have tested it all around the house and its...
