Quick question about the baby 10

[stolenfat]

Im in the middle of building a baby 10 tonight, i posted in another forum but didnt get the reply i wanted... sooooo

Can the baby 10 be run off of a 9volt battery?

The schematic calls for 15 volts, could i chain 2 9volts together to get 18 volts then use some voltage regulators or a chain of resistors to bring it down to 15v?
I'd much rather just use a 9volt!

hi there,
i rum my baby 10 on 9 volt with no problems.. the only thing you should may change are the led resistors... just to suit them to the 9 volt instead of the 15....

there is another advantage of using just 9V. the counter ICs trigger theshold is half the supply voltage.
so without using a trigger conditioner the common baby10 powered from 15V would require trigger signals of more than 7.5V...

so dig this, i finish it up right, i test it- nothing. Just one long tone. Anyways i go back and forth to try and fix it, checking my solders and stuff.... and blam I broke my soldering gun!

Bug!

i dunno homies. I built up the baby 10 rip off from curious inventor and kinda got that to work but it stuck at step 6 (weird)

then unhooked everything and tried the regular baby 10 schematics and didnt really get anything from that either. I mean it kinda worked... it seems multiple knobs effect the cv out on different steps. I havent hooked up a clock yet, just tapping the clock in the +v of the 9volt to get it step a quasi-random amount ahead. also, i used 1k resistors on the leds and they're very dim, maybe i should trim those down too.

garrr.... I'm looking through all my forest mimms stuff and cant find a schematic for a 555 clock generator- any one got a good schematic to run my 4017?

This thread may help, and it includes a clock generator reference.
