I can smell the propane long before and after this thing can detect it, if it ever detects it. I did many tests, releasing a bit of propane, waiting a while, then getting closer to the meter and trying again. It only worked when I pointed propane directly at it, ~15cm away, and waited a few seconds. Only tested with propane (LPG), which it's intended to detect. I kept it at its recommended height. Shouldn't this be tuned to detect even the slightest leak? This doesn't seem very safe since it will only detect it in a closed room with a ton of propane. Maybe a different review can clarify how sensitive I should expect a detector to be. Supposedly it's set to the Chinese gas detector standard. There's a variable resister on the board (bottom-right of pic); the instructions say nothing about it, maybe it can be adjusted for sensitivity. 12v is convenient if you can supply it. Comes with instructions which say it can operate at "DC 9-16V or AC85-260V", not sure if I trust the AC part. Has 2 spare spots to solder wires which can apparently shut off your gas valve using a "network signal". I'm assuming that's some standardized digital signal. The test button can also apparently open or close the valve. Top green LED ("Working LED") is always solid on. 2nd red/green LED ("Power LED") flashes green once a second when alarm is warming up (for about 180s), when it finishes I think it beeps, then it flashes green once every ~7s

Good Quality. Double-check that you actually want this 2mm pitch (distance between holes), because it's not meant to fit the usual arduino modules (which are 2.54mm).

Nice amount and price. Keep the ends from fraying by using a lighter, then put heat-shrink at the ends of the sleeving to keep it in place around your wires.

Best product of this kind I've seen. Heavy-duty is a good description; if it still moves you could attach rubber pads to the bottom or screw it into your desk. It comes in a box with description and instructions, lead-free, paint doesn't scratch easily.

Comes in a static-proof bag, can confirm it fits 2.54mm pins. I look forward to using it to control a power supply.

Tiny and cheap, glad they have adhesive. Search online whether you actually need them for your Pi or not. If I recall some people think these are useful for a Pi under extreme load and others say your Pi will never need them. I'll use them for unrelated power supplies. Measured the large one as 14.4 x 14.4 x 6.0 mm, the small ones are both 8.8 x 8.8 x 5.1 mm, tolerance of 0.1 mm.

By far the smallest and cheapest car I could find. Easy to take apart and see how it works (though be careful of the super thin steering wires). I bought it to modify so I'm satisfied. It also came with 4 road cones and good instructions. It can drive at an nice speed on hard floors and a lower but decent speed on carpet. I got a range of 3.5 m with antenna extended, it can be flaky around 2m. The 1.5V Battery in the car charges fast and lasts for a long time, and it'll last even longer if you cut off the LEDs which I did. Turns sharper in one direction than another (not sure if that was a consequence of the crashes and falls it endured). Photo shows the innards. The LEDs are normally secured.

Glad these are so flexible, the strands are tiny so they're hard to count but I roughly counted ~40 strands on my 20 gauge wire, meaning this type is good for either 2.5A or 3A

I love products with variety, so these heat shrink tubes will come in very handy for odd-jobs. There's not a ton of the small useful sizes but those are easy to find.

A nice diameter, amount, and one of the few here I could find that was labelled lead-free. The issue is it tends to ball up and not melt to the surface you want. I have two other different rolls of lead-free solder that adhere better, so I'll avoid this type in the future.

Glad they come in strips of 10, other sites force you to buy 20. The printed values on the strips are a great feature so you don't need a chart. Measured ~15 and they're basically within the 1% (one was 1.5% low, but that's nothing).

Got the windmill, it's really thin wood glued to either side of MDF, each of the 4 sheets is 1/8" (3.2mm) thick. Was shipped in thin foam, surprised there were no chipped corners. The brown paint isn't aligned well, but that won't matter if you paint it.

This was cheaper and cleaner looking than buying a bunch of connectors and wires and making it myself. Great value if you don't own all the parts already

Glad these adapters exist, they fit my needs. The connections are really tough to pull apart but I'm guessing that's normal.

So far it seems way better than the one that came with my Oneplus 2. It's less flexible than other cords and the connections are strong.
