    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...
