FeelTech,

It's great that you're taking this opportunity to get the community involved in trying out your upcoming signal generator. However, if you really want to get your equipment in the hands of customers who can tell you what works and what doesn't, you'll find them at https://www.eevblog.com/forum/testgear/feeltech-fy6600-60mhz-2-ch-vco-function-arbitrary-waveform-signal-generator/ and should probably hire some of them. The work they're doing in that thread is pretty amazing.
I TEA.

Can FY-6800 firmware be updated by customer or whole unit has to be shipped back to you?

Well looks like the other shoe has dropped. I'm interested in seeing the guts.

I definitely have a use for such a thing, and an application that would put it to the test, but I don't think I have the requirements for this.

Compared with users like fremen67 that definitely deserves a free unit, not to mention many others, I did almost nothing except starting the the avalanche a bit.
I still think I deserve my 3.1 firmware unit replaced, along with all the other 3.0/3.1 firmware units.
You have only one threat practically to look into it, but  I have a feeling that will be probably the only Feeltech post, or one of the very few, same like this "Amy" person that started the other thread.
And yes, would have been nice to actually answer my emails, sent long ago.

 Good luck to the winners, personally I will not give my private information for 100EUR, but some others maybe will do it.

Buttons sure look nicer.

I sort of hope that it is similar enough to FY6600 that the custom firmware fremen67 is developing can be made to work with little effort.
The only difference in specs I see is "Save function: It can save 20 sets user-set parameters and can be loaded at anytime." and that is purely software.

So if the only real changes are the PSU and buttons, that should be the case.
Even if they improved XO and OpAmp

But the big question is: Is the factory firmware upgrade-able?

7. Related achievements in the electronics field (included in eevblog posts, related electronic products created by you, you own blogs, tweets...) All can prove that you possess electronic related ability.

Translation: 'Prove that you are a electronics professional, so we may send you this hobby instrument.....'

LOL. You guys do not understand your target audience do you? At least not the western part (not sure about china internal market I admit)
Just send one to fremen67 already. He already bought two of your devices and is the undisputed leader of the eevblog effort.


Anyway: Not signing up myself. I do not do stuff like twitter and facebook.

Yes, just send one to fremen67, don't waste time, a good review from him may convince me to buy a new one and get rid of the old.

Yes, good idea to help potential owners of a FY6800 by praising Feeltech‘s support:
My FY6600-60 with FW3.0 suffered from known firmware-related „becoming a useless brick“ error, shortly after Paypal refund period.  The seller („echoii_mall“) promised to send a replacement when i pay additional shipping fee (which i did), of course i never got a replacement unit.
Contacted Feeltech, they promised to help - i never ever heard back from them. Chapter closed.

On the plus side on new FY6800...
They have fixed the ground problem with new AC power connector.
Front panel buttons and layout look good.. but was happy with old layout and buttons.
SYNC button is gone but there is now VCO button.
Added a new button labeled OK.  What is it for?

On the other side....
All the technical specifications of FY6800 seem to be the same as FY6600.
Frequency stability and accuracy specs seem to be the same.  FY6600 had frequency jitter and stability problems.
Are the output amplifiers the same? Distortion the same? Questions are not addressed.

It seems that this may be a repackaged FY6600 with a corrected AC power connector and new front panel buttons.

Not going to apply for free sample unit and give away all that private info.

It's only a "Free trial" ?  I think this competition should be in the "Jobs" section.  :)

That's probably exactly what the FY6800 is, and now that we've demonstrated that different op amps and XO make a big improvement, they'll be included in the FY6900 model, to be released in August/September.

Any free samples should be given to those who bought the "lemon" versions, to show some goodwill towards previous customers.

I still can't define "Free Trial", although with the conditions, I can see why you'd feel like you're On Trial!

I'm sorry to point the obvious, but, this thread doesn't belong in the 'contest' category. More like "lease in exchange of coming up with marketing material". So it belongs to "jobs", at best, but more accurately in "requesting free stuff", if there is such a topic.

Better to just send some units to the guys that have experience with previous Feeltech products (a few even mentioned above). Just shortcut the entire charade, it doesn't seem to be working that well anyway (2 followers on twitter as of now).

I'm not sure if it is quite that obvious...

I, too, am a bit confused about the "Free Trial" bit in the title.

For this to be in the "Contests" section, I would be expecting the five units on offer to be given to the five winners, for them to keep - but nowhere is this explicitly stated.  Quite the contrary, the use of the word "Trial" indicates that after the review is submitted, they will want the units back.

Choosing the winners as has been described is not unreasonable, nor is the requirement that they provide a review - IMO - but the units would need to be kept by the winners, otherwise this is nothing but a poorly presented 'con' to get reviews.

A bit too negative with the comments guys. I am sure the confusion between "free" and "trail" is due to Chinglish, we would not fair much better with lingo reversed. I am not participating myself (no twitter for me, I only follow local police alerts), but let some kids win a free sample and be happy with it. But yes, some acknowledgement for the active other thread (name has already been named) would probably help set a more positive tone to Freetech's own advantage.

Free units or not, Feeltech is getting a lot of free publicity from this little sales campaign.

Those of us with older FY6600 units have an obligation to point out the problems for new buyers. Many older units failed prematurely. The original design had flaws, like failing to provide AC mains grounding. And there are others.

But, perhaps, worst of all is the lack of customer support. Many of us have contacted customer support without getting response. Or, they claim you do not know how to operate the unit. IMHO they actually understand the problem or question but fail to address it.

New buyers should be aware of these things. As for me, my unit is finally working good, thanks to the help from this group. But everyone cannot solder these tiny ICs and could end up stuck with a poor unit. In my case, I am not signing up for this promotion. I do not like the way it is presented. And, I shudder to think about how it would be to deal with  these guys.

Free Trial, just like 6600 model was recalled, aka they stopped responding to customers with bad units.

My FY6600-60 with FW3.0 suffered from known firmware-related „becoming a useless brick“ error, shortly after Paypal refund period.  The seller („echoii_mall“) promised to send a replacement when i pay additional shipping fee (which i did), of course i never got a replacement unit.

dont squander the opportunity to repeat this great user experience by buying 6800 model now!!1

If FeelTech is indeed reading this thread, listen up.

You have a PR disaster on your hands.  Two entire software revisions of your devices were defective; one of which resulted in bricked units which either you or your distributors refused to repair or replace.

Your customers are hobbyists and talented engineers.  You took their money, and left them with a broken device.  You have given them no options except one: take your broken equipment that you stuck them with and make it work again.  The result of this is that they have reverse engineered your entire device lineup for this model series.  They have no reason to buy another one, because they have already made yours better, and have published the inner workings, schematics, and detailed information on how to modify these devices online.

If you want to mitigate this disaster, you need to act immediately: send everyone whom you sold defective 3.0 and 3.1 units a working device (revision 3.2 seems to work ok so far, I suggest you start here).  Your new device that you are pushing on us isn't better than the ones that have already been modified.  Your new device is DOA if you don't fix this.  It may already be too late.

It can be even simpler: just release the 3.2 firmware as a up-loadable file. 90% or better of the user community here on eevblog will next fix their own devices without additional cost to Feeltech *and* the device has potential to become popular if mistakes can be fixed and it can be played with


Also, my note above toward negativity was on complaining over the wording whether this was a contest and how they mix up words for free and trail.  Not worth it.
The bad firmware remarks are very much to the point. Note that I asked about upgrade able firmware earlier in this thread. Those are the valid complaints

I disagree.

If it was an item to keep, then it has appeal and I would consider entering.  If I'm just being loaned a unit for the purpose of giving a review, then they can go jump.

Whether the unit is any good or not seems to have been buried under a cloud of prior experience.  That is a separate issue - but it seems to be the overriding one.

If they release the file then other manufacturers will replicate the unit veeery fast. If it was an obsolete model then loss would be small but their new model its the same with rubber buttons and new psu (according to specs)...
Of course they could implement an encryption and decryption on bootloader but that's should be done on a newer model with pre-programmed bootloader, idk if they have done in 6800 but I am sure they are not gonna release anything for 6600.

The positive is that we will have a better enclosure for the opensource software ;D
