Will do! Just managed to buy two of these capacitors (only one should be needed, but costing less than 20 cents each, I thought it best to buy 2 and save one as a spare), will know whether it works momentarily.
EDIT: no such luck. The adapter’s behavior on my light definitely changed (no more turning off and then back on of its LED when connecting to the D3AA), but I tried to read its firmware a dozen times and except once, this was the result:
The exception was this time, when it almost worked:
The ^C after the error message was me interrupting the program about 1 minute after the “page load” error message with no updates.
Here’s how I rigged it:
Next thing I’m gonna try is to use both capacitors in parallel (I bought 2 after all) in the hopes that twice the capacitance is enough to bump things over into working.
Any further suggestions welcome.
