The GDuP is a microprocessor controlled buck/boost converter for a single LED driver application. The primary use of this converter board is for the Aleph Light engines in any single cell flashlight (primary and rechargeable).
Here are some pictures of the converter board.

Questions and links.
Does the GDuP have reverse battery protection? No
When will the converter boards be available? After the blackout period. Initially only light engines and completed lights will be available to recoup the majority of the NRE costs. After that the blackout period will be lifted and the converter boards will be put on the shoppe.
What will be the price of the GDuP converter board? TBD
What light engines will be available? There will be the GDuP Cree light engine and the GDuP Seoul light engine.
When will we see completed light engines? Status and updates will be posted as new posts on this thread and this portion will be udated as needed. Currently it's a rough guess that Seoul LEs will be available sometime this month (April 2008) and Cree LEs to follow.
