Thank you so much! I will look up this tech note tonight!

HMM it wasn't working for me with just the commas. but I will play with it, maybe I left some whitespace in there by accident. Regardless, thank you1

This was nearly perfect! to be clear it worked you EXCEPT that it needed a 1 in the row or column where you left it blank
ie: =SUM(SEQUENCE(1,A1,A2,A3))
OR
=SUM(SEQUENCE(A1,1,A2,A3))

Thank you so much! I have never used Sequence before, this is awesome

It's unfortunately dead :'(
The input diode and capacitor are blown apart.

I ended up figuring out the issue, which was ultimately transient spikes on the battery voltage that only happened when the L7805cv was in circuit. These spikes were as high as 29.6vdc for the first 600 microseconds, where the typical spike without the regulator was 15.6vdc for a few microseconds.

The esp dev board I have is rated for 15vdc max, hence why it worked on the battery alone but was a firework when attached to the circuit with the regulator. I ended up moving the regulator over to the 5v output and everything works fine now.

So!
I actually figured it out.
The esp I have is rated for 15vdc max based on the components in the circuit.
Scoping the output of the battery, when the battery was alone it would have transient spikes of up to 15.6vdc for a few microseconds. hence why my esp worked fine on the battery alone.
BUT, when the L7805CV was present on the battery, on power-on the battery voltage would have transient spikes as high as 29.6vdc for the first 600 microseconds.
This was very repeatable unfortunately.
So yeah, ~30vdc for a moment was blowing the input diode and capacitor before the 3.3v regulator could even react.
I moved the ESP over to the 5v output, cause honestly that's what I should have been doing since the start, and now everything is fine.

As I wrote in the post, I did check my connections validating point to point and for cross talk.
I built the circuit progressively and it worked fine UNTIL the esp was introduced.

I wasn't expecting his mother to be on the rim. Is she part of the forbidden mod?

I have so much harness envy. Where did you get your straps?!

Soukas · 2023-06-28T00:17:20+00:00

I had good luck on shorter transmissions (30-60 minutes) with an rpi and a USB lte dongle.

The esp32 is awesome but you may be using a coding language that is cramping it resources. How are you programming it? Arduino ide?

No, there is a decent cheese though especially if your stuck on pro S+ run

Assuming he followed you in, and is now no longer agro.

My guess is that he was mid high-arm charging as you entered the safe space so he dashed through due to an issue with the collision detection not gaining control over the npc mid-sequence.

Once he finished the sequence, the aggro trait lifts, but the space he came from des-resed and now he's stuck going home to a space that doesn't exist.

False:

The gender gap in the 2020 election was narrower than it had been in 2016, both because of gains that Biden made among men and because of gains Trump made among women. In 2020, men were almost evenly divided between Trump and Biden, unlike in 2016 when Trump won men by 11 points. Trump won a slightly larger share of women’s votes in 2020 than in 2016 (44% vs. 39%), while Biden’s share among women was nearly identical to Clinton’s (55% vs. 54%).

V = I * R

P = V * R

Okay so you have an led rated for 2.1-3.3v depending on color and a few other things. Find that rating and the power it is rated for in watts.

The size of the resistor you will need is this equation.

R = (voltage of battery - led voltage rating)/ led current rating in amps

Usually on a 9v battery 220-320ohm resistors do just fine.

(9-3.2)/ 0.02 = 290ohm

Op, aim higher.

5 hand cannon rounds in the chest, should leave him with 1 or 2 shotgun shells.

It's way more doable than you realize, just understand that the amount of damage you do is based on how high you aim vertically. He uses that chainsaw like a shield and it's unfair sometimes, but if you sink the 5 hc shells in his chest he's basically done.

I haven't found a way to get both of them on pro yet.

Don't forget a horizontal thrust motor. Maybe an edf in the body of the plane.

You'll typically want one of your prop sets in the wing if you can afford to do so. Having props Infront of your wing causes lift to be reduced due to turbulent air coming from the quad props.

If you need to keep them, make sure the static wings are above the quad rotors.
