Good notes

A colleague recently told me about the passing away of a couple of scientist.  Prior to this Jim Williams and Bob Pease were just authors of exemplary application notes. I must admit I always read a few of their application notes to inspire me before I embark on writting my own. I now realise there’s a lot more to learn from these guys. I also feel less inclined to tidy my desk having seen this article in the EETimes. More about Williams can be found on the Linear Technology website.

Digitally illiterate?

I’m very pleased that this issue is being recognised…

and now with the wheels on…

…motor connected via a chain and sprocket.  The motor was salvaged from an old Stannar stair lift.  Still need to design the control circuit to drive the motor, so for now it runs from a battery charger.  Also the steering mechanism isn’t finished yet.  But that’s not stopped Jessica from wanting to test drive it, albeit with no steering wheel.

The Extension. The dream becomes a CAD model

 

This is the first post regarding our planned extension.  Hopefully I will find the time to update this page as the work progresses. 

The image shows the CAD model of the proposed extension.  I’m pleased to say this is very representative of what was in my mind.  We can now look forward to many months of hard work to realise the dream.
