Questions... Does the 4069 inverter do just that? Invert my + signal to - signal? Then I use the transistors to switch on/off in the correct spot of the circuit?

Yes

hi,
If you have a sketch of your final circuit idea to post, it would be helpful.
How many buttons etc..

E
This is another option.
Are the 7seg LEDs common Anode or Cathode?

The photo you shared is my new approach exactly, the push buttons will be replaced with pulses from a picaxe microxhip. I have both ca and cc displays to use. My project is to control a sawmill up and down by inches and eights of an inch increments. User selects inches and 8ths with two different push buttons. Then either move up or a move down that will automatically move the mill up or down the preselected amount . All this is controlled through the picaxe program. What I am displaying is how many inches and eights the user selects to move. So push buttons are sent through the picaxe code and pullsed out through the picaxe chip to the 74192 counter. Hope this makes sense.

 

hi,
OK, so you do need a Decade Up/Down counter IC as shown in that 2 decade counter circuit, with Common Anode 7 seg LED's

Yes, I'm only counting up to 6 on the 8th inch display , and so far only 9 on the inch display, but I might go more on the inches I haven't decided yet. I've run a display like this for a counter 11 years ago 3 digits, counted up to over 200 and back to zero. It's been a while. I actually took all this off the breadboard to try this 4026 idea. Just to put it all back on.
The information peviously with the transistors won't go to waste, as I have to trigger a reversing relay powering a 12 volt motor drawing 30 amps after I get these displays working. I'm sure I will have to work a transistor in there somewhere. That's going to be for another rainy day tho.
I just got do do more of these little projects.

 

Hello,

When you can get hold of some UDN2892's, you can drive 8 channels with 100 mA max.

I will keep it in mind. Looks like they are hard to find

 

Got my test displays working on the breadboard. Looks good. Thanks for the help. Now on to the next step.
