Best and Cheap Portable LCD Digital microscope
does this work with the intel AX 200/ AX 3000 PCIe card aswell? im going to try it because i ran out of options
I don't think so, different format and slots...
Thanks for the information, I can use two lithium batteries in series with the module
I don't think so, this is for a max 4.2V cell...of course you may use as many cells in parallel.
Nice
Still running!
So glad I found your video. I am having the exact same problem with my blender, will try your fix strategy. Thanks!!!
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.
@@MultiPowerLoRd Check the panels, maybe there are some bad connectors.
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.
Just experimenting.
Thanks 🙏 Just bought a used one for the voice FX (not GTX, as I have my own pedal board for the guitar 🎸)
Nice! You won't be disappointed.
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 :(..
0.4 mOhm for four-wires short test is a bit high to me. I got a Hioki 3541 resistance meter. When shorted, the reading is around 200 nanoOhm.
I don't have it anymore so I can't redo the test.
What is this white potentiometer for?
TX power
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.
I need to replace a battery on mine, it has no numbers or any ref. #. Do you have anything on your battery?
I just used one I got from a ruined device, any cell will do the job as long as it fits inside.
@@viocaia ok, thanx.
Hi! What oil are you using, and which one would you also recommend for efiles?
Any oil for fine mechanism will do the job, like the one for sawing machines or watches...you can easily find some in any auto part shop

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.
SX9 doesn't have bluetooth. You have to connect the SX9 RX to any devices by cable.

@@IordanisFishingNets I'll test it with few mobiles I have around and let you know.
what can i do if water gets into it
Try to dry it, have some rice around...if it was any sweet drinks, clean it with water and dry. Maybe you are lucky...
Good info thanks
Glad to help!
Works perfect for automotive
Yep...
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!
Soon...and thanks for apreciation!
18.5 250ma would be ok for a 1202fx?
Kind of limit, but it should work...you need a double 18.5V AC !
Thank you ill try to fix my neace motocy.
Nice! Good luck!
I need this. Would it be better to keep the xlr cable balanced though? TRS instead of TS. Or would it not really matter?
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.
@@viocaia thanks, I had the cover off once to try to fix the button and after putting it back in place, the drive was much louder. Thanks!
@@johnlouiskluck I got it...so try some tape or hot glue to smooth it. Generally it's a very solid keyboard so don't worry working on it. Good luck!
many thanks!
Do this work with a guitar
Not at all, it is just a simple switch, the magic comes from the piano...
Czyli nie wszystko co jest drogie jest lepsze od tego taniego.
Probably the extra cost relay on durability...but for hobby YR it's a wonder!
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.
Of course you'll fix it! You have my positive wave!
Nice vid Viorel.
Hope it helps
Hello sir, I have a defective tc helicon power adapter. I tried a 12 volts 700 ma but it doesn't work. What do you think is the problem?
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.
Did you ever figure out why no midi out on the 5 pin connector?
In fact there is MIDI out, but needs to be switched on from a front button. It is working!
@viocaia can you tell me which switch? I have tried the "edit" "midi out". Toggled it to on and off, but still no midi out on the 5 pin.
@@bobnolan6452 That one! Check the cable.it should work. I tested my self on a arranger module.
@@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...
@viocaia thanks. I tested with known working setup and still doesn't work. Maybe internal hardware issue. I can work around this.
I need to do the same, but add a rocker switch to toggle the power on/off. Unsure if it'd add noise to the input though.
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.
@@viocaia Its not ideal but I was going to switch the ground input. Really wanted it on the switch on the unit itself.
@@sokoloft3 Interesting! Never though about ! Let me know if it works....
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.
@@viocaia maestro how do I see which version I'm using and how to update the TC Helicon Touch
@@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
Excuse me sir,is this device can do a wave like 7.83hz? Thanks 👍
Not so precise...I don't believe it can...

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.
You're right.
thanks for making this video. But i just want to confirm if it's ok to use lithium polymer ( 3.6v full charge) instead of lithium ion (4.2v full charge).
It's working with both li-po and li-ion
What is the output voltage of this device?
It's going to 27V
@@viocaia Did you test if the voltage is stable under changing load? I need it for 5V. Also - where did you buy it from?
@@YigalBZ Yes, stable and reliable. Of course, under decent loads. Check my other videos about it. You can buy from AliExpress, try a search there...

I think there is a filter on the 230V side of the power supply. Normally they use at least one set of two capacitors connected in series. The midpoint is normall connected to the ground (real ground in the wall "socket". The power supply you have got does not have a connection to ground - it's prbably double isolated. If the filter is inside the power supply, the described above, still needs to be connected, and I suppose it's connected to the negative power lead! So, if you measure between a "real grounded" system and the minus lead of the power, you will in fact measure the voltage in the voltage divider - the two capacitors are connected in series! Yes, I have also broken devices and components due to this issue! Karl
Right ! I found if I disconnect the capacitor going from real ground to the negative output the problem it's solved. Probably the capacitors are leaking a bit as the times goes by...
Dirty jobs :)
Yes it is! Belongs to a friend of mine, very skilled constructor, plumber, electrician...that kind of guy you really need to have around. He helps me, I help him! Ha! (and few beers too)🤣
