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...
daca scrie 20 pe el banuiesc ca e de 20w, deci in niciun caz nu incarca laptop, care are nevoie de 65w in sus
Nu am incercta sa incarc laptop pe USB-C..nu stiu ce sa zic..

Great video guys, this is exactly what I needed to see!
Hope it helps
Great testing! ❤
Hope it's useful
@viocaia I purchased it 😉
@@MrMarclauren Nice! It's decent tool for decent money.I'm using it.
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!
I'll look for...and let you know
@@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...kzread.info/dash/bejne/aWSGmsueY8LWdLw.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.
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...
Hi - It's the same for G1000? My friends G1000 stop turning on and I want to try to safe his instrument :D
There are few boards doing the same job, but they are compatible. You can find on eBay for 30USD max..,I preferred to DIY my own with classic transformer because I had the parts around.
have thesame problem...i really need a replacement power supply. where can i buy such?
You need the model with 2x18V AC ! Something like this www.ebay.com/itm/295920787554?_trkparms=amclksrc%3DITM%26aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D264183%26meid%3D748baf1454b44fa389fbb5cab5caa50a%26pid%3D101875%26rk%3D1%26rkt%3D4%26sd%3D293217179128%26itm%3D295920787554%26pmt%3D1%26noa%3D1%26pg%3D4429486%26algv%3DSimplAMLv11WebTrimmedV3MskuWithLambda85KnnRecallV1V2V4ItemNrtInQueryAndCassiniVisualRankerAndBertRecallWithVMEV3EmbeddedAuctionsCPCAutoWithCassiniEmbRecallManual%26brand%3DUnbranded&_trksid=p4429486.c101875.m1851&var=594114046936
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)🤣
Can the dso 154 output frequency and voltage to the aligatir clip, then conect aligator clip to piece of metal coil?
If you use the dedicated port...yes!
@@viocaia ty its like those rife machines so you can wind down later at night, sedative effect with lower frequency like earthing near single digits. I got a pwm thats conected to a 9v snap conector although its not build very well from ebay
@@projectdrivecitygrid Interesting...but I'm not familiar with that, I recall I fixed one from Calivita , a kind of very low frequency generator with a big coil...porbably you mean generating alfa or beta something...
@@viocaia ty that's pemf though if its like a coil. That can be energetic though. Only clips output max 9v from pwm to metal contact anywhere on person can work.
@@projectdrivecitygrid Interesting. thanks!
Thanks man 😊
Any time!
People want to see RMS wattage and although one can do the math to determine such, people dont watch to get the formula they watch to see you do the equation. It would help if you knew more about audio equipment too
Thanks for remarks!
This is cool, nice work do you fix personal mini disc players by any chance?
It's kind of difficult, I usually replace belts, or minor things like power plugs, batteries contacts and so... But if it's related to the laser or command boards, that's almost impossible to fix...What's the problem?
My grandma has this pc
Ha! Nice!!!
Lol i never expect someone make a test of this batteries on youtube, i bought them today in promotion and was cusious is it good or shit, to bad my date is like 2023. But still more eko then a normal ones
Well, It's nice to have info when we need it! That's why I didi it! Hope it's helpful.

Es un buen compressor DOd 866? me están vendiendo uno que tiene 14 años que se muy bien en U$ 73. Que opinas?
Can't say...better read the revues...DOD generally are good BTW.
its somehow late but tbh as soon as you see that the board is made from fr4 instead of rogers you know its trash
Kind of true
@@viocaia i found that the best way is to use 2 professional amps or leave tx as is (using mini-circuits zx60-112), 2 antennas and a circulator to divide between tx and rx.
@@vat8367 Circulator it's great
Came to see him do the funky chicken. Don't mess with a PS.

Hola que tiene mando a distancia
Originaly yes...Mine it's missing
Lubrificação. Calor e poeira resseca o rolamento. Eu uso óleo de lubrificar motor veicular. Fica macio e silencioso.
Yes, it was dry and even if oil was up, near the oring, couldn't pass to the axel. Now it's fine...for a while.
does the 9v boost run 24/7?
yes. I measured 0.3 mA quiescent current when it was set at 9 volts. This will drain the battery over time. I calculated about 200 days with a 1500 mAh 18650. so not great
Yes!
@@zeddpilsner4 How comes, I tested few modules, with different multimeters, not more than 170 micro amps on standby. I'll revise this in a video soon. But, the main advantage is that the Li-ion cell can be charged anytime we like! I don't really mind if I charge my multimeter once in 100 days! Come on...
Ce am inteles ,este faptul ca invertorul va functiona tot timpul ? (chiar daca multimetrul este pe off)
Exact! Consumul in standby e de 160 microamps, cam 0,0006Wh, consider o celula Li-ion 18650, cam de 8Wh,avem vreo 13000 ore de standby...sa nu uitam ca putem reincarca oricind elementul...sper sa nu gresesc cu numerele..
asta vreau sa o fac si eu dar 3d print. e prea scumpa din china! lol. mi-ar prinde bine niste poze ai clare
E cam mult metal...dar facem poze desigur
i just received one like this 😂 reported for refund
Good idea
This was very helpful for my project thank you very much for the experiment i asked for. Just one question what is the modules maximum output current when it boosts 3.7 v battery to 5v and how much input current does it need because i want to attach small components to my esp32 cam , thank you again
Glad to help
Great video!! 👍
Thank you! 👍
How do you repair the transport buttons on that encoder board. Some buttons on mine work and other you have to press REALLY hard to work...
New switch, but those tiny contacts can be open and cleaned. Check my video about fixing micro switchies. And thanks for apreciations😁
this juat happen to me and he pump was safe but a littel deformed and started crying cause i bought it with hy saving
Yep, they are using chapter plastic, try ti shield it with mica, or some to divert the heat. Mine it's working great since
Thank you so much for this video. Helped me so so much including which battery to order as I could not find this information via Google search. 🙏🏽🙏🏽🙏🏽

TO THE 6.680 FOLLOWERS OF THIS DUUDE ... HE DOES NOT KNOW A HORSES ARSE FROM IT´S MOUTH VELOCITY FACTOR IN RG58 IS .66 NOT 75 AS NOTED BY BROKEN BULB ANTENNAS ARE TESTET ATLEAST AND THAT IS BARE MINIMUM 1/4 WAVE FROM A N Y T H I N G.. A TABELTOB IN WOOD IS A THING METAL ON THE TABEL IS A THING TOO.. .. VNA.. THEN ALL THINGS ARE GOOD THEN NO IT IS NOT.. FARE FROM IT .. WHAT A LOAD OF CROCK..
What's wrong with you? I followed schematics from a bunch of designs I found on the internet. Google for collinear antennas and you'll see the same mistakes there. Please understand that I'm showing what I'm doing! You...being such a skilled and cleaver specialist, shouldn't be here with the rest of the world. Please move your rocket science to a higher level. As I stated, this channel it's entertainment firstly. I don't intend to teach anyone! And be polite, I never called you crock, BTW I wish you all the money I've done with this project! HA!
ARE YOU SERIUS ... YOU CAN´T TEST ANTENNAS LIKE THAT THAT NOT HOW THAT WORK´S... EARTH AIN´T FLAT DUUDE ANTENNA TESTING IS FREE AIR TESTING .. OR ATLEAST IN A STRING AWAY FROM ANY METAL OR WOODWORKS ... THIS IS WATCHING A BROKEN LIGHT BULB IN A COLEMINE
Why don't you make a video about how to do it the right way! I'll be happy to learn from a ''master'' ! Until then, my antenna it's working that way.
USUALLY YOU USE SIMIRIDIG OR 1/2" CABEL
It's RG45...check the other videos...

Yes, a very simple and intuitive tool to wind the coils. But did you see all the wires concentrated in the middle leaving you no space for the secondary windings to run. Do we have some kind of bearing support to make for the wire wheels to run on, so that, the layers can be neatly adjusted as coils on the bobbin?
That's true, I found once starting the first round to get the wire bobbin as far as you can, the angle to the new coil it's getting larger and the wire just put one after another by it self, also a kind of break to have a tension in the wire it's necessary.
Hows the latency?
There is no latency! This is ''analog'' FM, so receiving it's instant.
Спасибо за видео! Интересно было посмотреть об этом модуле.
Thanks!
Great! What is it that determines the quality of the microphone?
Let's start with the capsule itself. For a dynamic microphone like Shure SM58 (most of the rockers are using it on stages) the membrane have to be light and flexible, so a better response to both ends of the audio spectrum, low and highs. For condenser and electret microphones (like bulky studio mics or the one in your mobile phone), they are already pretty linear and good range, so in SX9 I'm sure the electret capsule it's pretty ok. In my situation, the megaphonic and flanger sound of this set it's because analog to digital converter. For saving costs I'm sure it's the most basic and cheapest possible! I believe the sampling rate it's max 22KHz, but for CD quality needs at least 44KHz. Also there is signal to noise ratio which have to be as low as possible (-in db). Overall for the money it's useful though. So there are a lot of factors to determine a good quality microphone, but I should start with a good capsule of course, the first in the chain.
@viocaia I purchased it 🤣
Hi there and thanks for the video! My machine works on maximum rotations, you cannot change the speed (the diode lights up). Do you have a guess what's wrong? Thanks in advance!
That should be a final Mosfet in short...so all the voltage goes to the motor. Replace the transistor.
@@viocaiaThe transistor that sits on the radiator? bdw93c?
@@MagicATR I believe so...if you have a multimeter on resistance/diode mode, you should see a short in between legs
@@MagicATR Yep, that's Darlington transistor, not mosfet like I thought before.I never encounter such a problem.
I have a MicroSolar 600 watt inverter that idles at a measured 350 milliamps. This is 4.5 watts at 12.8 volts. The big Victrons idle at 11-15 watts. Low idle power is possible, consumers need to prioritize this feature to encourage manufacturers to optimize it instead of making the cheapest product. Powering small appliances directly from DC is generally more efficient than using AC overall. Using smaller inverters generally helps but not all small inverters are low in idle power. Fancy power saving modes generally don't work well for many appliances as the power is essentially going on and off and interfering with their monitoring and control electronics.
Yep, that's a lot. You gave me an idea about a kind of light sensor with relay, connecting and disconnecting the battery after dawn. I don't have a inverter working on batteries but a MrPow MPPT charger. I'll check idle current too.
look here about standby current of my MPPT... kzread.info/dash/bejne/X6SBt7dqj8jAqtI.html
