components ordered

hmm..hmm and more hmmm.

Heaps of stuff to write about.

1. Designed and implemented a usb prototype board. I got the board made from uni workshop. Just a usb type A header, ft245rl and a parellel header to 
be connected 
to a ucontroller devel board or an fpga board. Works absolutely 
perfect!
2. Implemented software needed for project using java. Just a shell version for now; may be a skin using swing laterz. Multi-threading and what not.
3. Finalized components and placed an order through digikey.
4. AT4521 replaced by hrf-at4610; parellel 31.5db attenuator from honeywell. The parellel interface has a Vih of 4.2V - so had to configure the z8 outputs as open-drains; and tie to 5V using 10k's. A bit slow - but it'll do.
5. All tantalum caps to D casing.
6. Finalizing PCB - place an order Insha Allah by Friday. I checked with the PCB manufacturer - the story 
regarding COD's are true. So no payment 
until I get the prototype pcbs in hand.
7. Redesigned 10th order filter for 0.01R input to 50R output. Implemented using E-24 range of inductors. Unfortunately three of the values are not to be found with digikey.
8. AD8022 step up redesigned and recalibrated.

and heaps more.
