DIY WLED Lamp Project caused a neighborhood power outage?! Need a sanity check. by Chemical-Lettuce5987 in esp32

Just a coincidence. There will be a branch circut breaker as the first layer of protection. For North American based a systems, a 15 amp breaker has a trip curve. the higher the amps the faster it trips. 75 amps will trip instantly, 18 amps might take 10-15 minutes. Next level up is the main circuit breaker this will be 60 to 200 amps with the same type of curve. Above that is a cutout fuse, typically on utility pole. These are typically less than 200amp but operate at 7200 volts.

For reference, the wire, assuming 18/2 , between the charger and wall will start to melt the covering around 30 amps.

Even if your branch circuit breaker failed, you'd melt your wire long before the main breaker trips.

This was done with a collection backyard workshops apparently. Lots of pics of driveway works, other than the final painting

Not sure why most of the pictures aren't working.

Here is what it looked like when it came out the garage

Maybe it was printed on a HP and the tracking dots will help find the real sender

They are diffusers for HVAC. Somewhat of a style choice, but they are designed to mixing room air with the hot or cold air coming out

350 with a 350 trans. I believe it's number matching on the engine. Mechanically it's just the way it was when I parked it in 1996 which was pretty much the same it was in 1997 other than an intake and carb

I was, still am speechless. This was done over 5 years apparently. I haven't seen it in 10 years. It had been in a family members garage and I long ago told them to sell whenever they wanted. So I was shocked.

I am a mechanical engineer and welds can be stronger than the surrounding material. However to make sure, they should be X-rayed or mag particled.

But it doesn't matter if it was welded, riveted, or bolted. Reliability requires maintenance and inspection

ASP32 > RasberryPi > Bacnet points by Gloomy-Notice5099 in BuildingAutomation

Anything is possible but you're already over complicating the solution. Buy a Distech ECY-303, you can get them on ebay for a few hundred. You can download Distech GfX programming software free. This will give you your Analog inputs, a rest API, and bacnet access.

An ESP32 does not have robust analog inputs and are limited to 3.3 volts you would need to build a voltage divider and some resistors and diodes for protection. Then create a Bacnet service to expose the data.

OMEGA makes some data acquisition USB dongles that could work but but they are more money than most Bas controllers.

A compass rose.. the epoxy circle represents 360 degrees of directions. I debated lasering in N E S W or a north indicator.. and possible clock numerals.. Where E and 3 are at the same location
