25 sets + 375 extra diodes yet $8 less
So since each set has 25 diodes, 25 sets have 625 diodes, costing $21.24.
Thus total for 25 sets including $5.23 shipping is: $183.48
Hence each set is ~$7.5.
We have 25 sets, 1 for everyone (Total 8 ) except me (4) and jdcarpe (11), that means we have 2 sets extra, raccoon you can keep them as I know you will be working on more customs, or if someone wants to buy, they can do that, since you are ordering raccoon, that is up to you, and if someone wants more, we can increase the order and maybe hit new tiers.
Also, update on the switched. I will be packaging them as 25 switches, just in case any comes out faulty or is damaged in transit. This pack would be for $9.
Costs thus far:$6 - PCB
$13 - case
$7.5 - parts
$5 - shipping
$9 - switches
Resistors and LEDs extra.
