Does this baby look alright to you?? Subject description: stripboarded baby 10 for verification... |

Hi lovely people .
I have been wanting to build a basic sequencer for experimenting with my WSG and as a general purpose simple sequencer for some time. I noticed the baby 10 is a simple, robust design and easy on the components, so have made this stripboarded 8 step version. I was hoping someone could cast an eye to check for any obvious mistakes... As far as i'm aware it's o.k
The ledresistors aren't valued as i will work that out as I go, the pots aren't connected but the positions for them are on the board, and the rotary switch is fairly obvious. I was also wondering if I could use 1n4148s in place of the 1n914s as I have 1000's of 4148s but only a few of the latter.
Once again, I'd be grateful of any support. ( I love this site, it just gets bigger better and cooler every day ( aaah, gee.))
I've recently breadboarded the Thomas Henry linear VCO using the 8038 and had some nice tones and frequencies from it, substituting the 5000pf capacitor for a 47nF ceramic gave me a bigger frequency range. She throws some nice shapes on the oscilloscope so I want to eventually BB that one too. The JPeg of the sequencer is below for anyone interested, cheers for now,
Steve. :¬)

There's a wire link coming off pin 2 of the 555 which seems to go nowhere. _________________ What makes a space ours, is what we put there, and what we do there. |

Thanks Uncle Krunkus, don't know what I was thinking!?! I started the soldering, I also noticed that there's a link that seems to join one part of track to it's adjacent space! ( ear 5 near middle of board.) Demented.
1 thing, Can I get away with 1n4158's instead of 1n914's? I'm guessing I can but hmmm, (ask the Masters...) |
