With just a week to go, and two big boxes full of parts from Mouser on my bench, this week is assembly time.

On the last update, I showed off my new laser-made PCB boards, and now I have the parts to populate it. It's my first SMD design and I have to hand-solder everything as I don't have a reflow oven. So, just is case I mess up with such little time left, I have also ordered through-hole parts to make a perfboard functional prototype. The perfboard version will also be much easier to iterate on, as I use an Arduino Uno in place of a ATTINY841, which means I have enough programming space to include debugging and logging code over serial. I'm left with so little space on the 841 that I can't afford that luxury.

In parallel, I have Bst Polymerase for the wetlab experiments, to generate fluorescent sample to test my spectrofluorometer for the activated Calcien dye.

Wish me luck!
