Hey audioguru,
Thanks for your time again.
I tried making the second circuit of Bill Bowden.
I couldn't make the first becuase when ordering the LM1458, I ordered one with a "m" prefix. Unfortunatley I couldn't "pummel" the Suface mount chip into the prototype board. I threw it out the window instead.
On the second circuit, I loaded all the components in. I am confused with:
1.) The connection between Pin 1 of LM324 and pin 5 of the other. There are 2 mid way connections to other midway wire connections. I don't know "how" to wire this up on the prototype board.
2.) Again, pin 3 on LM324, don't know "how" to connect this up to the wire/channel/link from pin 6 of the other LM324.
It's all the mid connections which are throwing me off track.
3.) The LED voltage drop has prompted me to check the spec's on the LED's:
From the LED technical data, I'm unsure what specifes the voltage drop:
Vf typ. 1.85 (is this it?)
MCD is 3500
RED
Vr Max. 5
kingbright part no. L53SRCE
4.) The capacitor arrangement. I have connected the first one:
+ to slots away from pin 2
- to a spare slot (unconnected to any other component)
The second capactor:
- connected next to the - of the first
+ next to/connected to pin 1
I'm unsure if the capacitors are doing there job
5.) I will buy a voltmeter
I like the deep end.
Take Care
Timbo
