Yeh,

Many of us have thought "geez that million dollar piece of equipment is a little over priced.. I bet i could build one out of cheap off the shelf components".. Well I know I have.. RF Spectrum analysers made from dead tv's and vcrs, RF Sweep generators from the same equipment.. these with stability and accuracy enough for a hobbiest. How about Radio direction Finding (RDF) equipment? done.. even built a RADAR out of HAm 430Mhz radios..

Now read what this vietnamese Doctor did out of a desperate need..

In a poor country, what he did is special enough, he is working outside his vocation more credit worthy..

What has this to do with hardware?
