Yup - it is a lot of hard work but now and again you get a bit of time to do some of the more enjoyable stuff.
I've got a bit of kit to make tomorrow morning in < 2 hours for something I've never seen before to interface with a customers machine which they aren't sure what kind of input it will take and an input signal which could be between 0.1 and 90v and a frequency of 1 to 6000Hz ...... oh and I can only use components which are in our component drawers as the whole lot has to be up and running before lunchtime.
My afternoon will probably be spent drenched in petrol changing thousands of £ worth of kit on a conditioning system.
Any spare time will be spent continuing to design a high speed multichannel data acquisition system or maybe some kind of emulation card for the rigs we work on.
Never a dull moment
