The (*)555 Timer IC software has been use in countless of electronic project that requires the use of square wave (Astable). NE555 IC can act as a timer, delayed switch (Monostable), Schmitt trigger and simple memory switch. Here a a selection of Youtube videos that demonstrate the usefulness of 555 IC timer for electronic hobbyist.

The 555 Timer can help any electronic hobbyist and newcomer to build circuits with Astable or Monostable configuration. The application is very easy to use as the user only need to key in their desirable value of when the 555 timer should activates or deactivates; and the software does the calculation for the capacitors and resistors value.

The software is written by Andrew Clarkson, and you can download the software from http://clarkson-uk.com/555-timer/

Late this few weeks I’ve been hunting and finding Solar Panels which can be use to power up various items. Among the Solar Panel that I’ve found is listed below.

1. 14 volt panel – obtained from a hobby shop
2. 4.5 volt panel – scrapped from a damaged garden light
3. 2 volt panel – scrapped from some car accessories

Why would I need solar panel for?
Just to satisfy my hobby in electronics. The place where i’m staying (Alor Setar, Malaysia) always receives equal amount of sunshine, (near the equator), except for monsoon season of course. So I’m thinking that, it’s kinda shame if I let it waste.

Among of my plans would involve of hooking up one of these panels with a regular car battery and inverter to power up my backyard lamp and various electronic projects that depends on solar power. I’m looking for any good schematic to aiding me, not too complex, but good enough for a beginner.

I would appreciate any of your suggestions, btw.

Thanks!
