"I got the book "Make: Electronics" recently and rather than buy the prepackaged, overpriced kit they recommend from a specified distributor, I assembled the pieces I needed separately."

Additionally I discovered that they can also be daisy chained together without using any additional outputs on the arduino board (see link below). Tutorial on how to use the Shift Register: https://learn.sparkfun.com/tutorials/sik-experiment-guide-for-arduino---v32/experiment-14-using-a-shift-register. Tutorial on how to daisy chain them: http://lucidtronix.com/tutorials/40. Link to sellers website: https://www.addicore.com/Addicore-8-bit-shift-register-74HC595-p/115.htm. As you can see in the picture, you quickly get overrun by wires when using these."
"You will pay a little bit more for these pieces but the price is well worth the peace of mind as they will be shipped properly packaged and with a data card should you not be familiar with the pin layout of the shift registers."
"I like that Addicore goes the extra step and packed the ICs on ESD foam, and also included a pinout card."
"All worked as expected."
"Perfect way to get an additional 8+ channels on an Arduino."
"I'm using 4 of these in an Arduino project used to drive an 8x8 RGB LED Matrix."
"Worked great for my LED cube project."
"All 5 came nicely packaged in anti static foam with no bent pins or anything else wrong!"

"A nice programmer and surprisingly clean software."
"I had 11 ATMEGA328s (5x 328, 6x 328P) to burn bootloaders on: Took me about 10 minutes to do everything once I had the software installed (half that time was spent troubleshooting why it wouldn't burn on the first chip, where I discovered that I'd purchased the 328 instead of the 328P) - the hardest part was finding the .hex files in the Arduino IDE folder."
"This is a really versatile programmer."
"Works great, reads/writes/erases FLASH chips, reads/writes EPROMs."
"The software is glitchy and slow, errors abound when you try to program anything on this, but in the end this programmer covers a huge number of chips, it's very easy to use, the software has a huge variety of settings and customizability, and it always works as long as you're patient and willing to deal with it."
"I needed this to burn EPROMs for fbForth 2.0, a computer language I wrote as a file-based cartridge version of TI Forth for the TI-99/4A computer (vintage: early 1980s)."
"Ordered 2 units, but cheaper TL866CS model arrived (without ICSP that is advertised in product description) instead of TL866A."
