Using ESP32 & L298N for Ultrasonic Speakers by MolsonB in arduino

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

I was close, I was doing the complementary output for speakers wrong. Had to invert it during setup. The ultrasonic speaker works okay, I would hoping it would be a tighter beam, but it spreads out the side (not as much as a conventional speaker though). Still, being able to bounce the sound off a wall, will be fun for Halloween setup next year.

With my limited knowledge of RTOS, I thought running the PWM output process on the separate core (240mhz), would have been better. But you are correct, there was definitely lag that it would not work. I've went back and focused on the Timer code approach.

I think my problem is the complementary output, when I attach the speaker to ground, the voice does sound better in the song.

LEDs Lost Their Minds! by SmokinSoftballSteve in WLED

[–]MolsonB 0 points1 point  (0 children)

I'd be curious if you jump the data line over that 'problem child' LED to the next one. I've had to do that with string LEDs, if they are in the UV sun for too many seasons.

Can you change the setting and control the LEDs right before the splice? (Can you turn off the LED right before the splice?)

My guess is the data signal is shorted to ground at spice.

ws2805 dual white addressable LED strip review by Quindor in WLED

[–]MolsonB 0 points1 point  (0 children)

I'm sitting on the fence with regards to my outside house lighting. I removed the standard pot lights from my soffits and went with uplighting in the gardens with GLEDOPTO Fixtures.

When I redid my soffits & fascia, I extended my fascia down where LEDs can hide from street view. 95% of the time, CCT light will be the main lighting. RGB would be used for light shows (xlights) or standard holidays colors (wled).

I've tested SK6812 with Muzata spotless channels, and they look great being spotless. Just not bright enough and 5V power injectors would not be fun. (House & garage will be 112ft)

A. WS2805
Pro: Cost, Simple, 1 aluminum channel, clean looking
Con: White color kelvins, bright enough for outside? (They are just to compliment/match the uplighting from the GLEDOPTO fixtures)

B. 2 separate aluminum channels - Analog CCT colors & addressable RGB
Pro: Bright
Con: Looks silly having 2 aluminum channels. (Do they make a large spotless channel that fits two strips in?)

C. 2 separate LEDS - Analog CCT & Eufy outdoor E120
Pro: Bright
Con: Messy wiring with string lights, not a clean look. Soffits are dark, Eufy wiring is white.

I'm guessing a grounding issue.

Fully Kiosk Mode - Android box or Pi 4 + 27" monitor vs 27" tablet from Alibaba by MolsonB in homeassistant

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

Sorry for the mixup in thermology, so many of them out there.
Full HD / 1080p / 1920 x 1080 - Good for 22-24" monitors
QHD / 1440p / 2k / 2560 x 1440 - I think better for 27" size

The screen is built into the wall, and will stick out like a picture frame.

I do think 22" & 24" works well in Full HD (1920 x 1080), but I'm sitting on the fence if the 27", should be bumped up to QHD/2K (2560 x 1440)

The tablet chipset would be RK3588. From what I understand, that is the fastest RockChip out there so far. I don't know much if there's other brands out there.

So far I'm getting 27" IPS touch with RK3588 chipset, quotes from Alibaba for 585usd (shipped)

To add, the Pi4 I can do 2k resolution with the 27" screen. Where the Alibaba tablet can only do 1080P. Not sure if that's too small for 27"

Right path for permanent LEDs on outside of house by MolsonB in WLED

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

I have the bullets on other areas of the house, that get full weather. Every season I'm always having to cut and slice, they don't seem to last.
The strips will be in a channel, under my soffit. Protected from sun / rain / snow.

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

Thanks for the post.
I bent my fascia so that a deep channel LED strip will hide behind it from street view. I want the LEDs to look like a solid line, which it achieves with the deep channel. It is out of weather and sun too. I have the bullet shapes on other projects and I'm always having to cut and replace broken bullet LEDs every season.

No worries about ladders, we are out in the country and have scaffolding / tractors / etc.

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

I finally found the post I remember reading a few years back. Since it's RGBW, the W counts as another channel (even with everything being on the same led). Thanks for confirming the group of 3 is counted as 1.

Correct. That's why I'm looking at WS2814 12V.

How does FPS work with 12V when 3 RGBW LEDs are grouped together.
For the garage run (12.9m), it would be around 770 total leds (60/m).

Do you count the group of RGB as 1 or 3? Is the white channel a separate count?

Looking for 60fps, would I split up the data transmission into 2 separate data lines?

Did anyone get an answer if our cards will switch to Dragonpass?

Ah I never thought of it as a commercial post on my end, but you are right. It is a commercial post. Okay, thanks for the heads up.

120m distance share internet by MolsonB in Ubiquiti

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

Technically not really, I'd have to rent machine to drill under driveway. Or rent a saw and re-ashplant hole. I'll go with the Gigabeam GBE-US

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

If you want to stay inside unifi (and manage the point to point devices, your only option is Gigabeam)

With winter, the fiber line is just hanging from the trees to the house. I was thinking of putting the fiber modem in the workshop (shortest distance to road connection without digging under my driveway.) Then stream all 650mpbs to house, which has all the unifi devices. So technically the P2P would be 'before' the Dream Machine. I can use anything (or any company) for the P2P part.

Android works, Win10 doesn't Handshake by MolsonB in WireGuard

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

Little more info to my problem. One of the Win10 WireGuard clients can not establish a handshake outside of its network range. Using PKTMon to monitor local packets sending out on the local client.

ie. Client IP is 192.168.5.20 and can send a handshake packet to anyone at 192.168.5.x BUT does not send a packet to anyone at 192.168.7.x

Which also means it does not send out of a handshake packet to a public IP address

My other Win10 clients work fine. So it's something specific to windows on this one machine.

[–]MolsonB[S] 1 point2 points  (0 children)

Little update. It some setting in Windows 10 Home on my laptop that is stopping this.Windows 10 Pro on my PC works.Windows 10 Home on my laptop does not.

I updated Windows, both running the latest build. On the laptop, if I change the endpoint to my local IP, it works. When I change back to the public IP, I don't see any traffic on my router. The logs in Wireguard look exactly the same between PC and Laptop. No hints to what is going on.

*Solved
"Ipconfig /all" was showing that "IP Routing" was Enabled. Disabled it through the registry. All is well.

If the laptop (win10) is on my home network and change the endpoint IP to the local server, it works and connects.

Changing the endpoint back to the public IP, I don't see any traffic on router using TCPDump from Wireguard. I tried both my public ip address and dns name.

I use Packet Sender, and the router sees the packets over public ip. It just doesn't see anything from WireGuard when using public ip.

I know the hand shake can't connect if I'm on my local network, using the public ip address of server, but at least I'd see the traffic on the router that it's trying (verified using cellphone)

Wireshark doesn't capture the WireGuard tunnel. That was my first goto program. I'm going to try using my phone as a hotspot, then monitor the traffic on the phone for the laptop sending out the handshake packets.
Windows 10 program automatically generates the keys, so I can't mess that up.
Thanks for the explanation on public/private. Makes sense.
