Re: Activity L.e.d.s for disk A and disk B?

ok last picture... :) I promise :) I just need a small box to glue this to the front of, and a clever way (perhaps unused pins on the serial connector, for +5, Gnd, Disk1, and Disk 2 chip select pins.) that may be the ticket :) to get the signals to the small perf board with the 74LS04 instead of de...

Re: Just Purchased an Altair 8800micro :) #294

No issues with the kit other than a couple of missing parts. Installing the switches and LEDs was a bit tricky, Do the switches first, and I think if you use the method I described for that it may be easier... Just be careful with chip orientation. Make sure your chips are in correctly. Lots of fun ...

Re: Activity L.e.d.s for disk A and disk B?

Here is my "Dual Disk Drive activity L.E.D.s" Autodesk 123D Design file.
all the parts are seperate, although presented as one piece, the parts can be exported as stl
and 3d printed... the wholes will fit 5mm l.e.d.s :)

hope you like. :)

Activity L.e.d.s for disk A and disk B?

Thinking of building a little enclosure that looks like a small disk d...

Plus I was having issues with atmel studio 6.2. (He he)...I don't wanna get into it. Atmel AVRISP mkII usb programmer (...
