Very real article. STUDY STUDY AND STUDY: is the life of an engineer.


I would not be so drastic to say that if we stop for a moment, we become obsolete.


I worked with guys that refused to use new scopes, just the 1960s models. On the other hand they new hardware and troubleshooting in their sleep.


With software guys I agree that application software changes all the time.

For electronic simulation i use LTspice, the free sim from Linear Tech.

It does 98% of what the expensive pkgs do.

It doesnt have huge libs of parts, but

thats easily gotten around.

Theres also a huge user group with a great forum up on Yahoo.


For PCB lay out, i used to use Eagle but

the free version has a serious size limitation of 80 x 10mm.

That can do lots of designs but

for one job i needed to do, it wouldnt fit.

I researched what freeware a lot of people are using and

came up with Kicad, no size limit and

it is multi platform, Win, Mac, and Linux.

I use Linux for everything here so that is important.


Now LTspice is Win only, but the linux folks have

the Wine compatibility layer to run a lot of Win apps.

LTspice runs perfectly with it.


For EM simulation theres NEC in its various flavors.

With Linux i use xnec2c, and for Win theres 4nec2.

Both are freebies.


No need for the little guy to break his bank

with expensive tools.

Lots of great freeware out there!
