Hi,
I'm building the cave II and am new to making boards. I am following the directions close (so I think) and am having a great learning experience! I have run into a problem... The IC1 is on the parts list but not the IC2... My over sight cause there is two huge IC's on the layout. I totally should have seen that but I did not. No biggie. Also, I am ordering parts from Tayda Electronics which sell the LM78L05 but another over sight and I received one that has 6 prongs instead of 3. They sell one labeled LM7805. Is that the same thing? Any advice is welcome.
Thank you for your time.
you need the lm78l05 in the to-92 package (3 prongs) http://www.taydaelectronics.com/l78l05acz-l78l05-78l05-5-volts-100ma-voltage-regulator-ic.html
for the dub edition, both IC's are pt2399, so there are 2 of them per pcb
have fun!
