Nice! Do you have the link? Is it based on Austria Microsystems chips (AS5040 and similar)?

Yes I have. Do not read the product description. It's wrong.

Wait, what? So, if there's some external magnetic field, the angle data this thing gives will be wrong?
And how linear is it?

We can make digital compass chips, so why not use those with a magnet hovering directly above?
I don't know about the linearity, I should check this. Any idea how?

Edit @Kjelt:   thick-black, black.  What same color? 

I never learned that the unit of color was mm²

Bought myself a Hakko Dual Solder Reel Stand for my birthday (tomorrow).

I bought a 10 bit Absolute rotary encoder, from china. And it works!
But I had to take it apart to find the pinout of the connector, I can't read chinese colors.

To my surprise, I did not expect it to work with a magnet.

Punctuation is your friend.

Have a happy birthday.

Mine was 6 days ago but it should have been today when a heap of new stock arrived.
I joined the 20+ scopes club  well just for a few days.........

Happy Birthday guys

Hiya

Probably my last on-line shop from Maplin, I just couldn't resist:

It would be way cheaper to get 5" floppy drive and scrap it for stepper motor and a schmitt trigger and you have the best encoder (expept optical ones but they cost an arm). Main problem is finding 5" floppy drives....

Tautech, you should take a pic with those 20+ scopes to keep for posterity.

Thanks bitseeker but they're going out the door that fast it's doing my head in. 
Somewhere in this thread there's a pic I posted of a dozen or so destined for a classroom set.
Next order that'll be bigger still might be worth taking a snap of, but they're pretty boring all in boxes. 

All sounds like great fun but the gloss wears off when you need to unbox every one, ensure it boots, check and maybe update FW version, then Self Cal and check probes, compensate, assign to channel (fit color rings) and check 10x, 1x switch.
Yep all this latest lot need all that ^  each !!
More than four at a time is just tooooooo hard !

Gotta shoot off soon to deliver some and collect a demo unit.........

[Inverted18650]

Arrived today. So far everything seems perfectly fine. Fingers (tightly) crossed, more to come.

Kudos on the dedication to deliver a good out-of-the-box experience.

Yep, they look good, including the batteries. Nice catch.

One of my pending projects is to make a replacement quick-connect card since my 228 didn't come with one. I've located just about everything I need except the cable retainer clamp that they use.

Alternatively, I was thinking about potentially extended the PCB a bit and put either a Phoenix connector or banana jacks, instead of the screw terminals.

Ah the dark brown colorsettings of the frontpanels from end 70s begin 80s, just as with homes in our country.

Have you seen what a 5.25" FDD goes for these days? They start @ ~$50 + shipping.

[bitseeker]

Hmm, does that mean my closet will become a good retirement fund? Nice.

Sounds Like it 

The 360kb drives in-particular are getting very expensive as the 1.2MB HD drives dont work too well with DD media (basically renders DSDD disks useless when put back in DD drives).

[bitseeker]

Yeah, HD drives are fine for reading DD disks and writing to DD disks to be read by HD drives, but not for writing to DD disks that are to be read by DD drives. Something I haven't tried is bulk erasing the disks and then writing them with an HD drive.

One of my units is missing the PCB insert as well. I swapped it over when I did the power up test to see if the output was functional. I am going to lay one out in EasyEda tomorrow and get them ordered ASAP. Because of their size, I will get 10 of them made in a single lot, so your more than welcome to one/two. I will make the project "public" as well so you can check my work and/or directly order replacements...I will let you know as soon as I get it done, if your interested.

I don't know about the linearity, I should check this. Any idea how?

Linearity: Hmm. It's serial data out, so you can't just look at signal edge timing like: Put a flywheel on the shaft, drive from small motor via loose belt. Check signal timing.
Maybe: attach a long arm to the shaft, set it up with a large sheet of paper marked with the radial divisions. Or just a big protractor. Display the updating angle output, move the arm on the paper/protractor to see if the digital angle matches the actual angle, and where the resolution boundaries are.
You'd hope it wouldn't change with orientation of the unit relative to Earth's weak magnetic field.

The same setup to check for sensitivity to stronger external field. See whether the value boundaries (or even the direct value) change when you wave a magnet around near the unit.

Edit: Wow, you really have to be careful with the part number.

That's an    M6A2-38F10B-5C-2.5M  Which is actually an optical 2-wire quad-phase unit.
Yours is an M6A2-38F10B-5C-3M   magnetic sensor and serial data out.

Sounds great. Looking forward to it. I've been meaning to check out EasyEDA.

[MosherIV]

Just been to check out what is going at Maplins  they are going out of busines.

Just got these


An instrument case (bargin at £6)
Solar panel for keeping car battery charged (£10)
Plasma ball, always wanted one (£20)
