Hi guys, look what I found on ebay:
**broken link removed** for only 5 USD!
It can be easily converted into regulated converter.
But what confuses me is this:
**broken link removed** for 18,50 USD ???
Why is chip alone almost 4x expensive than completed circuit ready to use (that includes that same chip)??? Should I avoid the first one???
I need your opinion; finally, can I use this circuit in the car (perhaps with some additional filters, etc.)?
I apologize in advance if i don't reply to your posts immediately. I was awake all night (it is 7am here) and I have to catch some sleep!
