Hi there! i have built a climate box to grow mushrooms. It can regulate both temperature and humidity. The heating or cooling works with a peltier element. The air humidity is increased with an ultrasonic nebuliser. I have built everything modular, so that you can also reproduce individual parts. Have fun with the manual Step […]

When you need pulses of any sort, long, short and with variable frequency you can use one or two 555 timers. That works, is easy to set up and is cheap. But it also limited to a certain range in frequency and pulse length. If you want a precise pulse length you will need an
IntroductionAs you probably know, Iran has dry weather, and there is a lack of water in my country. Sometimes, especially in the summer, it can be seen that the government cuts the water. So most of the apartments have a water tank. There is a 1500 litre tank in our apartment which provides water. Also,

One of my class assignments this week is to use the BBC Micro:bit to interface with a Scratch program we’ve written. I thought that this was the perfect opportunity to use my ThreadBoard to create an embedded system! My inspiration for the scratch program comes from vintage handheld electronic games that my mother would get for me

This 3D printed switch will allow the user to turn a Makey Makey into a “finger slide” for a “click” in gaming or could be right/left arrows to scroll through presentations. The addition of right and left terminal mounts for the ground wire makes it flexible to meet the hand dominance needs of the user.

Project Background: In 2015, I started a kickstarter project of a miniature 3D zoetrope DIY kit. The next year, I started the version 2 of said project by further simplifying the kit and reducing its manufacturing cost. Sadly, both crowdfunding failed, but this is how the 3D zoetrope looks. *Zoetrope: a 19th-century optical toy consisting of

This project is a companion to my other Home Automation projects Smart Data- Logging Geyser Controller and Multi-purpose-Room-Lighting and Appliance Controller . It is a pool side mounted monitor that measures the pool water temperature, ambient air temperature and barometric pressure. It then displays the pool water temperature on a local LED bargraph and transmits via WiFi/MQTT to a

Clock generator I recently build a pulse generator and it does its job well. It produces pulses of variable length and at several frequencies. But the number of frequencies it can produce is limited and for many jobs the length of a pulse is less important than its frequency. E.g. when you are testing a
