Kaizer Huvitz HFR 8000 Frame Tracer Glasses 2016 test teardown

My unit is from 2016 written in the display as boot up version, found in the local E-Waste, so it is most likely defective or otherwise useless and worthless to the previous owner, Amazing mecanical construction, 3 stepper motors, 2 DC motors with high resolution encoders, many ball bearings, and cool solutions for moving parts. ARM cpu and FPGA , Flash and all the modern stuff.

I use auto generated subs, i am sorry there are a few spelling errors,
maybe one day they can do it better..

(Thanks to all my Sponsors / Traders / Swappers / Sellers / Buyers, without your support and constant flow of cool items in/out, none of this would be possible)

The Nidek ones can trace both sides at once. It is important to do both sides as asymmetry can occur in even very precisely made frames. The linear tracing accuracy can be better than a micron in some of these machines. This technology allows for the edging of lenses without the need for a template, and allows for an even more precise fit.

Damn those things have been on my teardown wishlist for years, I was never able to find one at a cheap price.

this one was on the top of the local e-waste container, i visit the place now and then to see what i can score to play with too,..

Small board is because the old design used a DIP EEProm, but it is no longer available in DIP form, so the board is there to make the SMD part fit the DIP layout. Got a remote receiver with the exact same thing, the old DIP microcontroller was no longer available in DIP, so they finished out the board stock with a DIP adaptor to use the new SMD version. 2 nearly identical boards, just a year or so different, but both originally designed for the DIP version, and they likely had a few thousand of the boards ready to use, just needing the microprocessor (likely a OTP PIC one, though it has only a house code on it, but with the one board likely dating from 2008 with DIP part, and the SMD adaptor from 2009) to be programmed and inserted.

[@TeardownOZ2CPU]

you are right

It may need an external terminal / keybord to use it.
For a test object one could use something like the outer ring of a ball bearing, on a cut can with grooves.
The error message could indicate a defect with one of the decoders.
The idea is likely using weak DC motors toward the meanical stop at the frame and measure the position with the decoders.

I love your videos; they make me feel as if I’m watching myself enjoying my favorite hobby again. Thank you-it’s incredibly relaxing for me. Please don’t stop uploading!❤️‍🩹

[@TeardownOZ2CPU]

thanks a lot, you are also welcome to browse thru the quite large collection of old videos, i think it is funny new released videos gain so much attention the first few days, but old videos almost dont get any visits, the units i show and talk about are all very old, so it makes no sense why a new video is so much more interesting :-)

@@TeardownOZ2CPU It's all to do with the RUclips algorithm. If RUclips deems your content not interesting, it's not popping up for anyone.

Given the limited market, this thing must have cost a fortune to manufacture.

When the machine locked up at the beginning, it may need to be reset using the serial console, if you manage to rebuild it it may be worth connecting a laptop to the serial port to see if it gives anything interesting.

[@TeardownOZ2CPU]

exactly, most of those boards runs an OS with a serial console enabled, even in release fw
