    Hand Crank Generator Here is the circuit of a compact hand powered generator that can awake little electronics by hand crank. This is a great vacation device that you can rely on to operate your small electronics. The prototype generates up to near 150mA of current at 5 volts, enough for a wide range of minuscule devices! It is easy to use a small...
    Hot Glue Gun Hack: Temperature Ready and Power Indicator Hot glue gun is an indispensable tool for electronics hobbyists and professionals. Reasonably priced glue guns (and glue sticks) are now widely available, but most of the low-end type have a serious drawback – the lack of a power status indicator! If you have enough skill level and patience, you can easily add a simple...
    PCB Laminator I used to design my PCB using one of the free pcb design software available on the website and then using the toner transfer method with an electric iron tried to transfer the toner from the paper to the printed circuit board. I must say that the end results were pretty good but not too good so I decided to find another way of...
    DIY SOT-23 Adapter I mentioned in a previous article that TO-92 devices are starting to go away. Do not get me wrong — they will be around yet for a long time, but newly engineered devices are mostly packaged in the tiny SOT-23 or the even smaller SC-70 outline. Since SOT-23 devices do not lend themselves at all to the bread boarding of...
    Power Indicator for the Water Softener This power indicator circuit is intended to be used as an extension for the water softener. It might be easier to just place a LED but it is better to make a rectifier that detects the presence of the 15 kHz signal generated by the 555 IC. Water Softener Power Indicator Schematic The rectifier is connected at the water...
    DIY Water Softener System Hard water has a high concentration of minerals, and of these calcium salts are the most troublesome. But there is a solution coming in form of a cheap diy water softener system built with the well-known 555 IC. Actually the price of this diy system is so low that even if this doesn’t work you won’t be upset. The...
    DIY Solar Tracker System The solar panels are operating at optimal parameters when they are at the perfect right angle to the sun. Unfortunately this is accomplished only if solar panels are rotated by the sun. This is the purpose of this diy solar tracker system or if you have an Arduino board then you can build this one that uses a servo. The solar...
    Rain Sound Generator – Sleep Aid in Case of Insomnia Insomnia treatment consist mostly of sleeping pills consumption but this circuit is an alternative for that and consists of a simple circuitry that generates a rain sound effect. The japanese researches were the first to discover that sound of rain has a relaxing effect. With the help of this simple circuit we can generate the...
    Voice Activated Home Automation Project Today’s project of the day is from J-J Shortcuts’s blog and is about the voice activated home automation project, a domotica controlled room. First let’s see it in action: This is the beginning of my domotica controlled room. It consists of a VRbot voice recognition module, an AVR ATtiny2313 and a 433MHz RF...
    David Moran’s Capacitor Meter Project Hi guys, I just received an email from David Moran and he sent me his capacitor meter project with pictures and a little presentation. Here are the details and schematic. Here is the schematic of my capacitor meter I built and have used quite a bit. It will measure from zero to 0.1uf with 300pf at mid range. It is an...
