The YiHi SX350 35W Chip at Varitube

[Kevinn]

Hey all! I had a problem with one of my chips, from the initial release (from Yihi) where my chip would not buck properly. Most of the time it would display "SHORT!" Luckily it did not occur with any of mods that I sold. This 50W upgrade fixed it!

I had that same "Short!" message with my SX350 chip (not purchased from Varitube), even with the 35w upgrade which supposedly 'fixes' it. I noticed with the 40w and 50w upgrades, I haven't seen it since, and I have even been using my mod now more than ever.

Welcome to the thread.

Just tested with a .2 ohm coil @50W. Turnigy 6000mAh 65C Li-Po. This is my problem child that wouldn't buck but the update fixed her right up!

Is your battery meter showing ANY voltage drop at 50w with a fully charged lipo?

None! Sorry the pic was of such poor quality. It was taken with my phone. I was actually firing it in the photo. This was my test build and the only one I have built with a Li-Po so far.

I've also noticed that the battery charge status is more accurate now. It used to display 4.31v when fully charged. Now it displays 4.20v...FYI

What project box did you use? Any pics of the inside? I'm waiting for parts to do a large lipo build myself

I used a Daier 125B. It was the only box that I could find that would accommodate the battery without removing the hard case.

I'm in my break room at work and would have to walk to a different hanger to get a screwdriver to open it up. Too lazy to do that right now...I'll post the pics in an hour or so.

I totally agree! What say you onedesign1?

They got back to me last night on the USB wire position. There's a chip in close proximity on the other side of the board to make soldering the wire from the other side not possible.

But I suggested then that when the workers are applying the glue to stress relieve that they lay the wires flat to minimize the interference we have to deal with. They said ok good idea ..... so we shall see in the future. But they did seriously consider moving the wires though which I think is again a good sign that they are listening to the feedback.

While I understand the points of concern with the wire placement, it's not very difficult to remedy this for an experienced DIY'er.

Simply mounting the charger board inverted would be a simple fix. While some may insist on the board being mounted in a conventional manner, it is not necessary(so to speak). I use a few different chips and configurations for my builds and have yet to find the SX350 USB board to be a problem.

We are not saying its a problem, we are saying it would make mounting it easier.

That is just AWESOME that they are even considering it! Seems like a High Quality company we got there in YiHi!!!

So I go to varitube.com to get the 50W upgrade file, click on the link, and I keep getting a white page saying "The address is not valid". Is anyone else having this problem?

burgmanncues I just checked it and it takes me to a new page for download....says No preview available above the download button. Sending a PM now.

Same here earlier - found you have 2 too many "//" after the https: . Removed them and it took me right to the page.

This is what you have: https:////drive.google.com/file/d/0B61oDGxskBGhcVJJd01hbzU2ekk/edit?usp=sharing

Thanks...

Ok I had this thought that the switch that comes on the sx-350 board one lead must be a ground and be pulling a high down to a low across the switch.
I see your drawing has a reference to a DNA board.


This leads me to the question has any one actually wired up a lighted switch to the sx-350 board?
And is this how they did it?
I am sure someone has done it.
Maybe I missed it somewhere.

Did you ever get a solid answer? Looking for a more detailed diagram of hot to do lighted switch when firing on sx350 for a newbie.

Its the same regardless of DNA or SX just hookup the switch the way I posted and it will work, I have one done and works fine.

The way that I wire my LED buttons is simple. I run a resistor from my button's positive lead to the positive pin on the 510 connector.

I then run the ground to the 510's ground.

The resistor used will depend on the LED's voltage. I use 2.8v LED switches with a 47 ohm resistor.

Hope this helps.

here this is how you do it for the switch to light up when pressed. View attachment 351623

What wattage do you use for the resistor also what type should I use carbon or metal film?

Resistance isn't measured in watts it's measured in ohms. The ohms of your resistor will depend on the required volts for your LED and the power source that you will be using. If you are using a 3.7v battery and a 2.8v LED, you will need a 47 ohm resistor.

Did that resistor mess with your atty resistance at all?

 

[Macaiah]

No. There is an insignificant drop in voltage due to having something else pulling from the battery. Not noticeable at all though.

I wire straight to the 510 because it also indicates that I have power going to my atomizer.
