The guy in THIS VIDEO uses a Markii Programer "in circuit serial programmer" to get his compiled code to either an ATMega 328 and for the AtMega Tiny.
In addition to using the Markii to get his entire program on the 328 or Tiny...
He also uses it to get bootloader code onto eigher of them so he can transfer future code using the bootloader and two pins on the chip.
Most of the Marii Programmers are from China via eBay and have long delivery times...
What are other ways to get your code... either an entire program... or just a bootloader... onto one of the AVR chips like the 328 or the Tiny.
Thanks for any help.
