Mailbag

Today I got a new delivery from AliExpress. A few weeks ago I ordered some 74HC595 shift registers and a bunch of blue LED.

That order was inspired by some articles about LED-matrix and LED-cubes. I also would like to try it and build up one of these cubes. So let’s see …

The shift registers I ordered 2 month before as SOP-16 package, but that shift-registers in DIP-package were delivered. After starting a dispute, the seller refunded me and with the second order I finally received the right ones.

50pcs 74HC595 SOP16
1000pcs 3mm Round Blue Super Bright LED
