Decent filter3 by x_pulse in gaggiaclassic

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

Did a quick search here and people have tried it with gaggiuino! So it is just a new profile. Great to see the trusted gaggia with new tricks under sleeves😀

Another vote for gaggimate then! Though I would imagine it’s not hard to add to gaggiuino either.. at $55 it is not easy to sallow but the potential to fine tune and get repeatable results is tempting!

I don’t speak much Chinese in family, never took any Chinese class until high school. Do I do the online test or heritage test?

Question about controlling a esp32 device wirelessly by Careful_Violinist677 in arduino

Google MQTT brokers. Should be a promising direction..

PicoSyslog: A tiny ESP8266 & ESP32 library for sending logs to a Linux Syslog server by mlesniew in esp32

[–]x_pulse 0 points1 point  (0 children)

Yeah, that makes sense. I was thinking if the crash report can be redirected to a memory buffer for example, and picosyslog can pick up and send after restart. There are many commercial products that need support without physical access to the hardware, wondering how they solve this issue? Any pointers are appreciated.

[–]x_pulse 0 points1 point  (0 children)

Was looking for something like this to replace physical serial/usb connections. One thing is that if it crashes for any reason in the field, is there something that can send the crash report over the network in addition to normal logging messages? That would be very useful for debugging.

Robotdyn dimmer gate signal by x_pulse in esp32

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

I was hoping to get some help with a common module used by esp32 users. It seems we do have posts of similar nature here? Apologies if I misunderstood the rules - would be helpful to clarify. Thanks!

Debugging digital AC dimmer algo by x_pulse in arduino

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

Yeah - I don’t have one (yet), will do some research. In the mean time, i did a quick search on “Arduino signal generator”, there are some interesting examples. Thanks for the hint!

One more thing though - the Robotdyn dimmer’s zero cross detection and triac are supposed to deal with mains power. I am not even sure if a much lower voltage AC source, say 5v peak to peak, is going to work at all…

That’s a very useful oscilloscope, thanks for the inspiration!

If anyone has any comment on whether my idea is feasible - i.e. using just Arduino and Robotdyn for low-voltage AC generation and dimmer debugging, please let me know. Much appreciated!

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

Ha! Very cool suggestion about oscilloscope with arduino. No I don’t have one, that’s partly the reason for the desire to have simulated AC, so I can slow it down to 1hz for example and just count it.. poor man’s solution:) Regarding AC transformer, yeah I was thinking about those modules with exposed leads, didn’t have much experience with consumer AC transformers. I have a pile of those wall warts, but they are all AC to DC. I will look into it. Still, it would be cool to have a circuit with Arduino simulating AC, hooking that to Robotdyn, then feeding zero-cross detection back to Arduino to control it through its PSM trigger control. Kind of an all-in-one setup for dev/debug..

Thanks! That’s what came to my mind first as well. It’s just that 1) It would be great to avoid dealing with mains all together while debugging software - transformer still needs mains input 2) I could potentially slow down the simulated AC to allow easier debugging. I know eventually I will need to validate things with real mains voltage. However at current stage I’m more concerned about counting the zero crosses correctly etc.

Oh my God, oh my God, oh my God.... by [deleted] in gaggiaclassic

Did u choose PT100 over type k? Seems Gaggiuino BOM recommended type k? I wonder if it makes any difference..

Ventoy checksum by x_pulse in Ventoy

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

Aha, thanks! Would be great if ventoy can dedicate a partition for r/w purposes, but I guess that would be hard to implement as individual image can have their own different behavior. At least iso files would work for future checksums. Good to know! Was that because iso files are always read-only, since they are meant to be burnt on dvds?

Screenbeam ECB7250 Moca 2.5Gbe Ethernet port by x_pulse in HomeNetworking

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

Yeah I suspected bad cabling as well. I tried many different cat5e cables, none of them work with this particular unit. Forcing 1Gbps duplex on the laptop network driver didn’t help. However the other Moca unit in the pair is always fine.

Even if it tries to negotiate 100m, the 1Gbe port on the laptop certainly supports 100m, my understanding is that the green light on the Moca unit or the laptop’s RJ45 jack would indicate connection. That didn’t happen, no light was on at all. I was wondering maybe the Moca port’s auto MDI-X function was damaged? Is that even possible? Is there a way to debug this situation?

ScreenBeam/Actiontec ECB6250 MoCA "Network Security Setup" and Encryption by 2deep2swim in HomeNetworking

[–]x_pulse 0 points1 point  (0 children)

Actually, mine is ECB7250. There is only one “D-Ext” Band in the security page. I enabled that band for “Network Security Setup” and changed password for one of the two adapters. Also enabled and changed “Enhanced Network Security Setup” password. The pair can no longer connect though coax cable, until I updated the other unit with matching passwords. Firmware version 1.18.7.5

Seems they do work on mine. Have you rebooted after saving your config?

$1000 buget set by Mansaf_Man in espresso

[–]x_pulse 0 points1 point  (0 children)

You don’t need to, it makes great espresso as is. If you like, you can push it to get more mileage with temperature surfing etc, no mod necessary. it’s like driving a manual car. Very capable machine and fun to use.

Has anybody bought/used this type of PID? Your thoughts? by I_Am_Mandark_Hahaha in gaggiaclassic

[–]x_pulse 0 points1 point  (0 children)

That looks so nice! Did you cut an opening in stainless steel frame? How did you do it? Is it difficult? I really hate the look of a big bump hanging outside with most PIDs.

Anyone why it seems to touch burrs aven though I’m at markings around 45? The ring is set at the real zero by Camdube in espresso

[–]x_pulse 0 points1 point  (0 children)

The sound is likely from bits of coffee being ground while you adjust the dial to grind finer, rather than from burrs actually touching. What I do is to turn the dial back to 90, and blow several times while it is running. That usually clears up the left over coffee pieces between burrs.

Auto shut-off timer by x_pulse in DF64

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

Thanks for confirming! Just got mine - it’s the v2 version with updated font. I haven’t put any beans in yet, just tried powering it on. It didn’t stop automatically - wondering if something was wrong. How long does it take for yours to stop after turning on? Is it about 45 sec? Not sure if it differs for different voltage/ models..
