Hey, I'm making a laser security system from a school project, which is supposed to ring the buzzer when laser light is not incident onto the ldr but in my circuit the reverse is being done, ie. The buzzer rings when light is incident onto the ldr.

Here are the components used

Bc547 transistor

Pico buzzer

Breadboard

9v battery

10kohm resistor

Led

For the past one year I've been using focus by MDS. Its a really good extension but wasn't really designed for edge even though it works and i got bored of it.
Any good recommendations??

So im trying to 3d scan my living room which is around 3-4 metres long. I don't know if the scans are not coming up the way I intended because of the length of the room or my im doing it wrongly.

I'm using the java version of mc, and I recently installed a new version of sklauncher(v4). I was previously using v3.

I want to transfer all the world from v3 to v4.
