lol...I just ordered one here in philippines which looks like your's from the photos but was even cheaper...roughly $100.   It has yet to arrive.  I don't expect much...If it can engrave some text on plastic and wood I'll be happy.   If if can reproduce line art 1/2 decent that would be great.

You can return it now. The 1500mW rating is not honest. The laser diode in the laser module has a CC driver at 175mA, so for a blue laser at 4V, 40% efficiency, that translates to 0.28W of optical power.

I just did a test on the module, and I was very disappointed. Reported to Amazon, requested them to delist that item and its ilks OEMed by the same company (NeJe).

I didn't order from Amazon, they don't ship to Philippines.  I ordered from a site here in Philippines called Lazada.  Return might be possible if the unit is defective, but they aren't as nice about returns here as Amazon.

If you're interested in modding your engraver with a bit more powerful unit let me know ::)

Ha Ha! I have a 12 pack of the lithium AA's coming probably tomorrow! If it chews through them what I deem "too quick" then it's gone! As soon as my lithium are delivered i'll change them out, I suspect the ones in it just now will be normal AA's. They will only be put back in if it leaves/sells!  :)
I've heard it chews them like no tomorrow and also heard people who've had theirs 2 years or more and still on the 1st set of batteries too. I think a lot depends whether the supercap is ok or not as far as batteries goes. A pot luck thing! We'll see...

I have the Brymen 867s which I really like as a meter, the 289 was more because I "wanted/needed" it.....ya know "wanted/needed" or the world would end? LOL  :-DMM

If I end up not "really liking" the 289 i'll get rid. The 867s gives me all the features and accuracy etc i'll ever need.

I've had a quick go on the 289 and think i'll end up "really liking" it anyways......WHAHAHAHAHA!!!   >:D

Nice 1 buddy! They get a good write up and plenty people to ask for help or tips with the Rigol scope.

Hope you enjoy it!  :)

Just bought an OEM Keithley GPIB-to-USB cable, GPIB extension/ coupler cable, and Keithley Pico-Amp meter! I swear that's it for a month! I promise to spend time designing and conducting experiments instead of shopping for gear for the next 30 days. Pinky swear, cross my heart and hope to die...lol

I still need to hack mine, but truth be told, I havent used it much and the free trial period hasnt run out. Ive been using my analog Tek gear most the time..

Did you find any issues while installing the new firmware? Did you follow a YT tutorial or just know how to do it without the help?

  With the floppy drive replaced with one of those USB units the old girl should be with me for awhile longer.
Do you have a link for that USB unit? My TDS744 may need that.
I bought it quite awhile ago on Ebay...but here is a new listing of the same item   https://www.ebay.com/itm/Slim-Floppy-drive-Emulator-Tektronix-Oscilloscopes-1-44mb-26-FFC-1mm-Pitch/291291990998?epid=1254493285&hash=item43d25b0bd6:g:Zr8AAOSwopRYd0oS

Operation is not like the PC emulators, so be aware of that.  There is only one floppy image stored on the USB stick and you don't have to format it special.   The instructions are typical badly translated but once you get how it works it's reliable and fairly easy to use.  Cost is $95 plus shipping.   I know the slim pc emulators are much cheaper but they don't work.  I bought one first and gave up trying to make it work.   I suspect that you could buy a slimline PC emulator and mod it, but I don't have the patience to bother.

The Gotek emulators would likely work just fine if you ran the HxC firmware (STM32) on them instead of the garbage that comes pre-loaded on them.

The Gotek has a standard 34pin header connector, but the Tek scopes used the "laptop" solution: 26way FPC cable, so you'd have to make an adapter to connect it.

No, one of them, the other was here already. Hint: Impulse buy inspired by one of Dave's videos ...
