Tell us a little about yourself ?

---

I've been working with electronics for well over thirty years now and have designed a huge variety of different products, from Aircraft Auto Throttles, Air Data computers to distributed Audio Systems for home entertainment.

While I still do some consultancy work, I'm mostly focussed nowadays on my design company – Motochello Inc. - and the production of motorcycle audio systems and headsets.

How do you use Proteus in your working day ?

---

I use the Proteus tools for all my design and layout work, including some pretty complex and detailed stuff. For example, the MC-200 Audio system which has a touchpad display and an amplifier and distribution system. Some challenging problems was to layout thee amplifier system on a 2 sided PCB and keeping noise levels low.

Here is an example of a typical layout of my Audio PCB.

3) What do you like most about the Proteus Design Suite ?

---

The things that I most enjoy about the Proteus Design Suite.

• Very easy learning curve.
• The ease of generating new components.
• The ease of generation custom footprints.
• For simpler projects the auto routing is a dream.
• I like the operation of the rats nest on more complex PCB’s.
• Simple design rule interface.
• Price vs performance is incredible.
• I have laid out well over 100 PCB’s and would recommend this package to any engineer that needs a comprehensive PCB program for a reasonable price.
