You may be right.Besides a Flashaholic I am a Trackaholic!!
I have been working on lowering my expectations and NOT putting too much faith in people[primarily reliability]….very few people are as reliable,considerate and responsible as myself!
,another wolfdog quote:
Expectations beyond logic result in disappointment.
The Guy from DHL[Phone conversation] said that my Tracking number is a USA Tracking number,not China, Italy, Germany ect.
Maybe,this package originates from China, Neal has an associate and/or warehouse in El Monte,CA. OR Compton, CA.[Address on First package] it lands at this warehouse and they slap the label on it and then shipped to me.
My guess is it is originated from CA. in that Chinese owned warehouse and then shipped. It is FREE shipping so they are not rushing. Even when my FIRST order got close to me[MARYLAND] ….it took 4 days to go the last 100 miles!Finally arriving via USPS.

ELECTRONIC NOTIFICATION RECEIVED: YOUR ORDER HAS BEEN PROCESSED AND TRACKING WILL BE UPDATED SOON
If sitting for weeks in Neal’s mystery warehouse in Compton sounds OK to you then sure.
Seems more likely DHL has a huge international sorting center in Compton and you have a “US” tracking number which only means you don’t get any updates while it’s overseas. Rest assured, if it’s in some private warehouse past customs things would not take this long.
Any idea what keeps the LED around 5 amps in turbo? I think it’s more than just the forward voltage cause you see the LED spike up in current when changing modes.
No, it’s using a .015ohm resistor as the only current limiter, it’s a standard FET driver, no regulation.
To be regulated the resistor would be on the gate side of the FET and the MCU would sense current output (voltage drop over the resistor) and alter the FET’s pwm signal to maintain that voltage at a set point.
There’s what appears to be a smaller SOT-23-3 FET on the board up at the top (in my pic) but I’m not sure what it’s there to do…I do know both of the large FET’s are simply in parallel (all 3 legs are parallel between the pair which IMO makes zero sense, why waste money)
