what about control of humidity levels? Is this an off-the-self window AC unit? I've read those can keep at most 55-60% of humidity levels in those rooms. Flowers need more like 90% humidity, veggies/meat 85-90%.
Hello there. I built my own board and I couldn't upload my code just the way you did. Arduino IDE tells me "error: Invalid head of packet (0x00): Possible serial noise or corruption." Can you help me?
It’s strange sometimes like you said you had a soldering mistake, i would have thought that the board would not even spit anything out, but sometimes you can see it…. That and decoupling capacitors are so important
Hi Sogn, because this is recent, could you link your Github project you mentioned will do in the description of "Arduino Data Logger | Qt and C++ Code Review" ? A few people have been asking for it, me included. Thank you in advance.
@@newsogn5148 This is why I am beginning to dislike Gmail. Replies are hidden so deep in emails. I just saw your reply. Thanks for the info. I am going to try a griddle the wife was throwing out which I believe will get hot enough without using the thermostat which i believe still works. I just need to get a thermal tester to see. BTW. What type of solder are you using? I have paste but yours looks more liquidly than what I have. Thanks again.
Hi, I would like to know how did you wire all esp PIN. 6 months ago I made my own board esp-based. I use your same model ESP WROOM 32D but no procedure to boot the chip has worked. Can you help me please?
I actually made a better(I think) video about this take a peak I go over the circuit….. do you have a capacitor from io0 to ground that can cause issues
@@newsogn5148 thanks for your answer. If you want I can share with you my schematic. I have contacted various maker and everyone show me different circuits and different methods to program esp, but no ones work
well he seemed to let it die a death,no mention of it on the eev website either,looks like he was left with egg on his face,why make a long series of vids with no real conclusion?
@@paul.alarner6410 I think he wanted to sell them like the ucurrent but I think he couldn’t make money on it… this was before the dps modules and cheap gear really took off
There are so many mill designs where the gantry is sat at an angle including yours, why? what's the difference between that and if it sat vertically? thanks!
Honestly very little, it’ll work both ways I’m sure…. The idea is that we are using a cheap linear rail if the center of mass is to one side of those rails then one of the bearings will bear the majority of the weight and the other could have a negative force on it…. It’s a small detail, but it’s in an attempt to maximize cheap linear rails
it's an really incredible work, I want to create this project. sir is it possible to shear your python and arduino code? if possible please send on my email: (najmul.eee1996@gmail.com) Thank you so much sir
Thanks for this video! It's helping me lay out my own board. I'm sure you've seen the ESP32 DevKitC schematic, where in the bottom left hand corner they show their fancy USB to UART converter that also has the IO for controlling the EN and IO0 pins with the DTR and RTS signals. When I saw that, I got scared that these signals are also needed for communication during the upload process. I know that, for example, the ATMega328P on most Arduinos requires weird voltages on the reset/enable to put it into download mode, and might even be modulated. Just to be clear, the EN and IO0 pins on the ESP32 don't require any advanced modulation during the upload, right? It looks like the only action those two pins see are right at the beginning when you manually put the chip into download mode. Your USB to serial adapter isn't doing anything besides TX and RX? Thanks.
Hi, I am also designing a desktop CNC milling machine with working area around 200 X 200 X 40 mm. Here i am facing a problem here. However i have compketed the most of the design. When it comes to force analysis i have no clue how force will act on machine parts during milling process. I belive the forces depends on the material and spindle properties. But i dont know any formulae. Could please suggest me any book or material so that i can figure it out
I believe the esp32 datasheet says the boot strapping pin is latched to whatever value it took on reset, so you don't actually need to hold it down for the entire duration of the upload. I'm about to try this project, so I will find out for sure pretty soon :)
Hello newSogn, basically I'm trying to create a data logger for climbing related research, if you could share code, it would be awesome, thanks for a great video!
Thanks for the explanation ! I would like to reproduce the same thing for a similar project. I would like to plot data from ADC value stored in SQL database. Is it possible to have the source code of your project please ? thanks
I couldn't read your schematic very well on my screen. Can you link to a closeup image of the 3.3V power circuit section (like in the upper corner at time 2:55)? I've been meaning to try JLCPCB out. Good to hear you have had good success with them.
I am actually going to try something a little different right now I just have the HLK 5M03 going to the esp32 with some input capacitance, but I think I will try to get a 5v supply on there and then use a linear voltage regulator to knock it down to 3.3v that way i don't get the power supply voltage drop when I turn on a relay......
How well did the flowers hold up? I'm debating this same idea for flower arrangements for my daughters wedding. Making them isn't the problem, properly storing them is.
for a one time use, my wife would just turn the temp down in the apartment for one day and make sure they stay as cool as possible, also she would just order them to come in as late as possible then make them the night before. so there are ways around it for one use, but it is nerveracking.
no it was just loose valves, I finally manned up and adjusted them at 210,000 miles and its been a much smoother sounding car, I recomend doing that sooner than I did, because then you can see how your maintenance schedule is working.....
@@IgorD33on mine the RPM was lower, like maybe 2000, it is still not perfect, but yes they were loose. Did you inspect the rocker arms and bearings ect, how did they look? you might have a different issue, I also held a screwdriver to different parts of the engine and then you put your ear next to the screwdriver and use it like a stethoscope, figure out exactly where the noise comes from.
