Router recommendations please (Also: Different wattages?!)

.....there is a new one out and you can buy the PCB, the reprogrammed IC and the March 2018 issue of Silicon Chip magazine and build one for less than half the JayCar price.

Good news. I have the first generation silicon chip unit from the 90s which uses an IGBT. It’s failed twice. This unit seems more robust. Hopefully I will be able to just drop the new PCB into the existing die cast case. Looks like $10 for the PCB, $15 for the micro controller and $8.20 for the online magazine. Plus a few additional components.

How did the earlier one perform? If the new one performs as well as the speed controller/soft start in my Bosch MOF 1200 it would be excellent IMHO.

I got the copy of Silicon Chip and it looks a pretty straight forward build.

How did the earlier one perform?

OK while it was working. Both times it failed was when I was using a 400W Metabo drill with a paint stirring paddle. I don’t think it was a very good design.

Any chance you could PM me some photos of the article so I can price up the parts before I commit to buying the PCB and chip?

Cheers.
