Many people have tried, but an easy and accurate way to measure laser output without the proper equipment is yet to be discovered

Nah, not really. Its like asking, "how can I make a car on my own?". Its not really impossible, but you'd be far better off going to the dealership and buying one.

No you can't anymore, months ago someone here found a way to make them using thermal heads that were being sold on ebay, but when the heads were all sold there was no way to make any more meters.

l You can coat a small peltier element painted with laquer mixed with activated charcoal and then use a multimeter set to the mV range to measure laser power. Only paint one side of the peltier and glue the other side to a big piece of aluminium with thermal adhesive.
Then calibrate it using a real powermeter.

Easy in theory but a bit more involved in practice...but not impossible!
