The new boards for the Illuminated Overdrive have arrived! I am very pleased with the new design. I was able to shrink the size of the board and fit it into a much smaller space. This has allowed me to have all controls and clipping switch mounted directly to the board. And that’s a big deal, because it means that not only is there much less wiring needed, the board is also now held securely in place. It is also now much easier to remove the board after construction, in case it ever needs servicing. This is turning out to be a highly versatile board size, so I plan to make it the standard outline I use for all designs that use this box size.
You may notice that you only see two opamp chips instead of the usual 3. Don’t worry, the third chip is still there! It is now living on the underside of the board. To save on space, I opted to use an SMD version of the ’1044 charge pump chip that is used for the voltage inverter/doubler circuit. This is no problem, because the only difference between the SMD and full-size versions of the chip are the amount of power they are able to source without burning up. The Illuminated Overdrive only requires a tiny amount of current from it, so the smaller sized chip is well within its safe limits. In fact, you would be able to power several of them from one chip and not hurt it! No reason to eat up all that space with a big chip when you don’t need to.
So, yes, I now have the parts in stock again to build the Illuminated Overdrive. If you have enquired about one recently, I will have one built for you very soon, and if you’ve been thinking about ordering one, now would be an excellent time.
And have you noticed, they are black? It was totally worth the extra money; they look beautiful – as any Illuminated Overdrive should be.
