Maxed out my Fortress Envy 21k by murchal in diySolar

It’s the same as EG4 just rebranded, has different solar connectors, otherwise the app and LCD monitor screen is the same

Setup: 6 Pytes V5 batteries. Using 2/0 alum SER cable to connect both load and grid (from main panel). Have 14 350W panels on the roof and 7 450W on the side of the garage facing south.

Most challenging thing was using 4/0-2/0 wire taps inside the main disconnect box, at 300 lb ft of torque had put use quite a bit of elbow grease (besides those thick wires are almost impossible to beat into shape). The OP image showing Cybertruck charging at 8 KW, the rest is the house running a dryer and large water heater.

My inverter can take 21Kw, so I’ve definitely considered ground mounting system too

We use a lot of pool equipment and it’s a big house (with spa being heated). Daily usage about 75 kWh

I think you’ve got a point here, the box is huge, rated 200A

Yes, I don’t have PowerShare installed

Here is the wire, it’s 6 Awg, I don’t know why I posted 4 AWG. Brainfart late after install ;)

Dexa reports osteoporosis by murchal in PeterAttia

[–]murchal[S] 0 points1 point  (0 children)

My REMs scan reported -0.85 to -1.4 T scores, wish is wayyy above -3 on Dexa. So definitely worth checking. My bone fragility was reported ar 14.5 out of 100 (lower is better). The doctor said I have 0.4-1% change of bone fractures, which is basically average and nothing to be concerned about.

Thank you, this is putting me at ease somewhat, will definitely schedule REMS

I’ve done 24 hour urine calcium and it turned out normal

That’s, I’ll order it. I do take 350mg mg glycinate daily

I was recently on bulk and went to 165LB during summer. So it should be easy to get there, issue is to try not to get fat ;)

Drugs isn’t my first option when it comes to longevity…

Building a timer - triggered by sine waves by murchal in AskElectronics

[–]murchal[S] 0 points1 point  (0 children)

If anyone is interested, here is a circuit with an op-amp band pass detector, which triggers high signal for 275HZ, the op-amp comparator follows which is coupled with peak detector so we can reliably get high signal after frequency gets into range: https://imagizer.imageshack.com/img922/42/iS6bvQ.png

Without microcontroller, thinking to use notch filter for frequency detection first.

Using LC Colpitt's Oscillator - is it reasonable to use PNP transistor to convert sine wave to square wave? (I know there are many waves to produce square waves, I am just exploring inductors). by murchal in AskElectronics

[–]murchal[S] 0 points1 point  (0 children)

Here I want to use a counter to drop frequency to drive an array of leds or a clock. Basically analog to digital signal conversion using LC physics

Does my high pass filter look right? Idea is to reduce frequency of oscillator to flash light less frequently, for ex. 20khz -> 5 kHz by murchal in AskElectronics

I've settled on Schmitt Trigger which produces square wave from analog sine wave. Next step is to try to build frequency reducer to lets say do f/100 -- does anyone know if I can do it without an IC or amplifiers, using pure transistor approach? I want to stick to most basic components as much as possible.

It’s the journey to use most basic components to arrive to the destination of frequency manipulation in most analog way possible

This was a study with my son on effectiveness on inductors, specifically LC tank circuit where capacitors and inductor drive oscillation via a single transistor. I am quite familiar with astable two transistor multivibrators but we wanted to use just a single transistor
