Don't take them like a user manual or the Bible of DIY… I'm interested in hobby electronics, audio and solar green energy, everything can be dismantled and fix…made by humans of course I'd like to share my experiences with solar projects, studio recording, video editing, LoRa and many others...

Hello. I just received one of these. There appears to be a small potentiometer on the output side. I am just wondering if this is for gain. I can't find the data sheet online, but it keep being pointed in your direction. Any help would be much appreciated.
Hi in 1.07 you mesure 4.3amp but you do not show where you made a test and then at 4.19 you test the battery resistans how much resistans they should have to be good? thank you in advance for any feedback
You see those 4 contacts inside the case, or better 4 contacts on the vacuum itself, those are for the switch and for supplying the extra motor for rotary brushes. So you can touch with the ammeter those for switch and the motor should start.I'll do short about soon. As for the internal resistance for 18650 I found until 40milliohms are ok, they say like 20 to 80 will be ok...I rather found more than 60 to be ''tired'' not so good for power applications but still good for lighter or arduino…stuffs like that. Here we need current , so I suggest my configuration it's need.
Right! The output, it's alternating current. Most of the wall power supplies comes with direct current, this one has no rectifier and filters on board, bare AC.
Thank you for sharing this! Could you share for how long have you had these panels? Normally they are covered with 2 years warranty! Have you tried replacing them? Did you raise a complain to the manufacturer? I am asking, because I will probably buy the same, due to lack of other models in my area! Thanks
I bought this from a local provider. They replaced the ruined instantly without asking me to send the bad ones. Eventually I realized they replaced those from their own stock and the factory didn't make any effort to solve the situation. It was a clear malfunction on the factory ensemble line, as long as three of the panels had exactly the same problem.
I purchased the device - the 5V output. At first it looked well with my Arduino project: the battery is well charged, and the arduino project is working well under load, both when connected to external power (through the LX-LCBST) and when the external power is removed, so the battery is providing the power. However, there is a strange thing: When power is connected, I can turn on and off the arduino project, with no issue. When I turn the device off, without external power connected, the Arduino will not power up. Any idea?
Interesting...probably the Arduino input/load it's a high resistance value that the module doesn't see like a load, and it's not turning on the boost converter from stand by...try to add a 1-10 K in parallel with the power input
@@viocaia It is strange. The charging goes well, it works well if starting with IN power connected, and keeps working well if the IN power is disconnected while in action. Yet it will not start working with just a battery connected. 1K ohm resistor did not help either.
Try to reverse the connection...if the left become lower than right, it should be the cable…even the connector…but if you have steady lower output, it's the speaker
hello, thaank you first for your video. It is very usefull for beginners. Could you explain in a paper A4 this connection please? I have the cx3400, in stereo mode i want to connect one passive subwoofer. I will use the sum sub output? The gain sub in which level is good to be?( i have it in 0db and my amp protect is on occationaly. IF i dont use the sum sub output mode, one sub in which channel is good to connected? than youuuuu
In fact, for subs doesn't matter if it's stereo or sum, I use it in mono anyway. If you don't sum, any channel will do the job. For the gain, there is no standard level let's say, it's up to you and your ears. Usually the power amplifiers have a clip LED, so take care not to see that too often...so use common sense.
@@viocaia because i have only one 15" passive sub. So, if i connect the sub in "R" signal channel.. the "L" music not playing. On the other hand, in sum "R+L" .. the sub will play both , all music. There is difference between this options or i make mistake. For the gain, i understand, ok. (Thanks very much for your time , and the information. 🙏🙏)
@@stefanoskas4799 At very low frequencies, it doesn't really matter which channel is playing. Mp3s are usually mono at those lows. So any of the low outputs will be ok. Don't think about loosing any music signal.
Hello everyone! I got 2000W version and each day i´m performing a decreasing in power production. At beggining the max production was 1850Wp, and day by day it is decreasing the production by ~20W less everyday, now is producing max 950Wp. Anyone has same problem?
What I found kind of strange, my install it's like 1600W panels...I had peaks from SUN2000 like 1450W, so I know it's almost correct, but under really hot summer days, full sunshine though , the power went down around 950W...that's because the panels are overheating in the super hot summer sun. Nothing to do.
@@viocaia Very weird situation because in same conditions (on same temperatures) with 3KWp solar panels last year everything was ok with high performance with 1850Wp. Will try to check and if i repair i will coment below to share a resolution if.
In fact i did not understand what you are trying to measure, you should use different approach, two interconnected splitters with equal cables with known length and loss, one acting as splitter and another as combiner could tell you more. While taking measurements in both directions if you disconnect one of the cables, the left open ports should be terminated. Ofcourse results should be devided by two, or better use some complex realtime maths, if your VNA support it.
La mine nu a mers. Probabil au facut ceva modificari ca sa mai cumperi cabluri de la ei si bluetooth adaptors tot de la ei... Am incercat pe doua telefoane, chiar si cu Rx la Tx si invers. Telefoanele nu detecteaza chargerul meu mppt 75/15. Chestia e ca chargerul decupleaza LOAD abia la 6V primiti de la baterie (in loc de 10) deci poate ca e defect, proaspat cumparat :(
'I don't have the charger anymore, so I can't test again. It's very possible in your case to have a clone. There are some looking identical. Original post in Romanian: ''It didn't work for me. They probably made some changes so that you can still buy cables from them and bluetooth adapters also from them... I tried on two phones, even with Rx to Tx and vice versa. The phones do not detect my mppt 75/15 charger. The thing is that the charger disconnects LOAD only at 6V received from the battery (instead of 10), so maybe it's defective, just bought :(..
If its anything similar to the GH2, no chance at a clean liveview over hdmi. Im trying to do the same thing you are but with a gh2… the gh2 outputs 1080i50 over hdmi outside of playback mode; which isnt supported by most usb capture cards. Even my blackmagic capture card doesn’t recognize the aignal half of the time
I couldn't make it so I just gave up. I'm using a Sony A6500 which gives a perfect clean HDMI output. But I'm still using my old GF2 for stills and videos.
hello . i have sx9 microphone and i would like to use with mobile poco x3 pro.what is happening and the microphone is not working.it needs to be connected via bluetooth with the mobile phone. Do you can help me ? thank you .best regards.
Awesome review Vio! And for this price looks like a versatile controller. I thoroughly enjoyed the midi track you recorded in Cakewalk, very old school. Would love another video with the controller used in modern DAWs like Bitwig, Ableton etc. Thanks!
From my stage experience, more than 40 years, I found balanced matters for long, but really long cables. For connections like few meters doesn't really matter. I prefer to use one of the hot wires to ground for better shielding. Of course, for having a three wires microphone cable. Let's say a classic cable, with metallic mesh and white and red hots...finally, balanced maters when there are long distances...tens of meters at least.
Good day kind sir! I have the same keyboard and the “save” button is warn out and the padding around the floppy drive has moved and it is loud. I wonder if it could be serviced easily?
It should an easy fix, replace or clean the switch..I don't know about floppy, I can't understand what padding…if it's the cover? fix it with hot glue.
Thank you for this video. Couldn’t find instructions for the same pedal but instead of korg it says PS-100 and on the back Foot-switch 93 made in italy by fatar. Yours solves my problem: the wire with the spring broke in my case so I have to put some new springy wire to make contact. Wish me luck.
Check the polarity. TC-Helicon should have plus on the outside ! So inside pin. Usually plus it's in the middle but TC-Helicon it's reverse polarity. Cut the wires and reverse them.
@@bobnolan6452 It should be USB MIDI off...I don't have the keyboard so I can't check it, but I recall it was working for sure with classic MIDI 5 pin...
If you apply a power switch after the transformer you need a double one, because there are two hot 18V AC and ground..you need to cut both hot ones! But a simple switch on the high voltage input will be fine.
good night maestro!! I have a TC Helicon Touch, and I use an arranger keyboard, I use the midi cable on it, but I noticed that there are some notes when I sing, they go out of tune, I use the hardtune effect, I don't know if it's the setting
I found sometime, absolutely aleatory kind of mistune...possible from the software? But it shouldn't be on MIDI which is precise about notes...maybe changing the effect will fix it.
@@Rafamill2012 I'm not familiar with Touch, but it seems like you have to connect it to your PC and use Voice Support to find any information, also for firmware upgrade and so. Check the manual here.. mediadl.musictribe.com/download/documents/tchelicon/voicelivetouchcompletemanualengv1-2.pdf
Great video, i am looking to make one of these but for 915MHz, do you have the original dimensions? Specifically the 100mm section at the feedpoint and the 80mm section? thank you!
@@viocaia is the center section connect in a T fashion like the first segment? It looks like an electrically isolated 3/4 wave section... where the radiating elements are the first and last... is this correct? forgive m y simple questions, i'm new to this ;)
@@joearcuri3377 I can't give you details, this antenna was a cheap chinese one, I didn't saved the schemtic and dimensions for 900MHz, I have thsoe for LOra 868 only. Please look at this , maybe it can help you further...ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-70R8ie3_pDY.html
This sort of doesn't make sense; what did you calibrate the NanoVNA with? If you calibrated it with that 50-ohm SMA terminator (as well as an open and short) at the calibration plane, then just measuring the same 50 ohm load should have given you an exact 50 ohm result on the Smith chart.
