Just like everything else on this vintage Hofner Colorama II, the electronics have been treated badly and need some attention. By “badly” I mean that they have been left in a damp or wet environment and the pots are scratchy or cut out completely. The output jack also needs to make better contact. This can hopefully all be fixed with the help of some electrical contact cleaner, but first I’m going to remove all the parts from the pickguard. This isn’t strictly necessary, but since I’m restoring the whole guitar, and the pickguard also needs attention, this is the route I’m going to take. Firstly, here’s the whole pickguard/electronics assembly. As mentioned in another post, the beauty of the Colorama is how the entire electronics circuit is attached to the pickguard and can be lifted out in one go: Here's how it looks from behind: The knobs are removed, revealing some rather disturbing evidence of damp. Check out that rust! Rather that turn the whole pot by accident when I’m unscre...

  This 12V or 24V high-current DC Motor Speed Controller is rated at up to 40A (continuous) and is suitable for heavy-duty motor applications. All control tasks are monitored by a microcontroller and as a result, the list of features is extensive. This high-current motor speed controller is based on a PiC16F88 microcontroller. This micro provides all the fancy features, such as battery monitoring, soft-start and speed regulation. it also monitors the speed setting potentiometer and drives a 4-digit display board, which includes two pushbuttons. The 4-digit display board is optional, but we strongly recommend that you build it, even if you only use it for the initial set-up. it unlocks the full features of the speed controller and allows all settings to be adjusted. The microcontroller will detect whether the display board is connected, and if not, the speed controller will support only the basic functions. in this simple mode, it will function as a simple speed-regulated con...
