So I bought a few HW-070 PWM controllers to control some LED strips. They have a B100K five leg potentiometer with switch (they have a detent you have to click past before it turns on). I desoldered the pots from the board so i could put an extension cable between them. However after doing so the power output from the board seems to remain on but at reduced power even when the pot is in the off position (the LED strip glows weakly when the pot is in the off position). The pots function normally otherwise. Unfortunately I didn't notice until I'd already done 3 of the 4 boards and i don't have a spare pot to test with.

I've been looking at getting a second hand drone for some basic hobby-level mapping. I understand the P4 pro is generally considered to be a good entry level drone for mapping, however there's a P4 advanced being sold near me for a pretty sharp price compared to the pros. My flights are usually going to be out in the country in wide open areas, minimal EM interference, preplanned and always in visual range. So I feel like I won't miss having the 5.8ghz link and the extra terrain avoidance features, or is it still worth paying extra for the pro?

Location/temp range/specific trip description: O trek and general Patagonia trekking March-May 2019 below snowline as well as some regular travelling. 0-22 degrees C (32-72 F). I usually hike in NZ.

Goal Baseweight (BPW): No specific goal.

Budget: Approx USD700-1000ish for items I don't have yet/replacements where necessary.

Non-negotiable Items: Would prefer not to replace any owned items but still open to it where there's a good cost-to-weight-reduction option to be had or I've made an incorrect choice. Open to all suggestions for items yet to be purchased.

Solo or with another person?: Solo

Additional Information: Red is for items I own but am unsure about,

Hi all, building a wake rail and just wondering if anyone has/knows of some culvert pipe going for free/cheap around the Auckland area. HDPE or PVC, 250mm or larger and around 6m would be ideal. Cheers
