Tesla PowerWall 2's are very expensive (14kWh, $10k~$12k) My power bills average $600 to $700 per 60 days. That's f'n ridiculous and stupidly expensive. So back of the envelope, say if I drop my power bill to somewhere around $200 per bill I'd save ~$3,700 per annually. So I'd pay off the PowerWall...

Long story short; I'm about to get solar for my house. Any recommendations from you knowledgeable lot? I'm sure there's an expert in here somewhere. Effectively my only comments are that I want my install to be "battery ready" so I can plug a PowerWall 2 into it once they finally arrive do...

I stumbled across this yesterday and even though it's not updated very often (12-14 hours it seems) it could be of use to us.

At least I KNOW the reason for failure & can fix it. Nothing worse than NOT knowing, which happens so many times, when a flight goes wonkers. But at least I can laugh about it, and move forward. It's only a test mule for the much larger project and there will be 2 of us looking over each others...

Hi Rex, If you have a look a the tread below this one you'll notice a "magnetic apogee detector + timer" thread. In there's a link to a Magnetic apogee detector as well as timer that is $59usd. A little more pricey than what you might be after but it would be dead simple to use for apogee ...

No sir. Given we're in the southern hemisphere everything is upside down and back to front, right?!?

The name's been decided and the shirts are already available for order folks. You can find them here.

There already is one, it's called THUNDA!

So the question is, you coming?!?!?!

Sure, it might just be "back of the envelope" calculations but I found this read quite interesting...

CAN'T WAIT!

I wonder if it's too early to book these dates for annual leave at work...

I thought about trying to make a club style system with a single display and 4 or so transmitters . I was aiming to get a compass bearing to each transmitter and the coordinates of the last received signal. That system would have the display stationary so size wasn't originally a concern, how big (...

For low and slow it's perfectly fine but I'd steer well clear of it for more aggressive flight profiles. My Orange Revolution went to Mach 1.8 no problems, and 21500'. I guess low and slow are are subjective terms :wink: I was referring to West Systems for airfame construction and T2T. I got really...
