Thank you for your help and for the offer, which I accept, to 3D print a lid for the metal box I am going to buy.

If the box you use is right for you, it will also be good for me. So, in order for me to buy the box, please tell me the address on Ebay where you bought yours.
So, if my "LED and key buttyons" is the same as yours, the dimension issue will be overcome.

I bought the LED and key buttons that I have here:
At this address you will find an image with some measurements of it.

Did you use any cover for the buttons, as Clough and Jason did, or did you leave them in plain view coming out of the holes?

Thanks for your help.
I didn't know about the existence of that material for making labels. It will surely be of use to me.
Thanks for the information.
Could you please tell me if you made the green cover for the buttons or if you got them in another way?
And if you bought them, can you tell me where?

Thanks in advance

Thanks for the help and information on where I can buy the display case.
Since I don't have a 3D printer and my milling machine is not a CNC, I won't be able to do a decent job of drilling the holes and engraving the words on the box lid so that it looks good and essentially functional.
I can see in your work that the holes and writing on the lid of the box was very well done. Could you please tell me if it was your job or if there is any way to buy it?
If I can't buy the box ready made, I'll have to look for some other solution that will never be as perfect and functional as yours.

Best Regards

Hello Doreen,

Perhaps you can try to download **FROM HERE** and search the information you are looking for.
I'm not sure it is there, but you can try.

Hello everyone.

Upon arrival of the "LED and key display", by my mistake, I "burned" the board F280049C. No longer lit LED1 and LED3 and no smoke was produced.
Before the error, it seemed to be working fine showing information on the display.
The error could have been one of two:
a - having powered the USB port from a bad power source or,
b - trying to use stepp motor driver TB6560 i may have made the wrong connections.

Then I ordered another board that has arrived and it works.

Now I have some questions:
1 - In the "LED and key display" the button S1 is not used? I searched the Claugh42 movies and found no answer.
2 - I have used the stepp motor driver TB6560 for other purposes.
Can I use it temporarily in assembly? Has anyone tried it?
3 - I do not have a 3D printer to make the box for the display. Does anyone know where I can buy one that suits the purpose?

Best regards,

Dias Costa

Hi Phil,

Thanks for your help.

Phil: As far as I know this wouldn't work with this display without changes to the code, the structure of the display is completely different to the key n LED display, not sure about the interface without reading the spec's.
DC: I will wait for the arrival of the Led and key display.

Hi Zan,

Thanks for your help.

Zan: My led and key board came in two days so why risk it?
DC: I hope the one I ordered takes only two days to arrive ... Usually it takes longer.

Zan: Have you got the stepper turning?
DC: I haven't reached that stage yet.

Hi Phil,

I already flashed the TI board but because I don't have the display (which I already ordered), I couldn't see the output. There were no error messages, but I would be more confident if I could see any output ...
Can I use an "LCD Display and Keypad Shield" for Arduino?
If so, which pins to use in the shield?

The Arduino shield, identical to mine, can be viewed here:

Thanks in advance

Hi Phil,

Thanks for your help.
I've tested the board and as far as I can understand it works well. The voltages are correct and once mounted on the TI board, the power already reaches LED1 and LED3.

It happened to me the same as to Zan ("the display connector pins projection under the board fouls and shorts into one of the small jumpers on the board if it's pushed fully home", but tomorrow I will cut the pin concerned so that the assembly stay robust.

If it wasn't for Zan's message I would still not be aware of the problem, because I don't have the display yet so I can understand what's going on...

For those who have not yet assembled the board and since the terminal block once assembled covers some of the information printed on the board, it may be a good idea to take note of that information before mounting for ease of use.

Hi Phil,

just finished assembling the components on the board and I don't think I made any mistakes.
However, if possible, I would like to test the assembly before moving on. Can you, please, tell me if there are any tests I can do to make sure I haven't screwed up?

Thanks in advance

Hello Phill,

I'm sorry Phil, my message dated 03-11-2019 should have been written as follows:
Yes, please, I'm interested in the component set.

Best regards

Hi Phill,
I am portuguese and I live in Portugal.
If you still have an available PCB I would like to have it.
If there is such a possibility I do not know how I can pay you for the board and all expenses. Will it be possible through PayPal?

Best Regards

Hello Dave,

I'm interested in building an ELS for my EMCO Compact 8 lathe, so I started looking for an incremental rotary encoder that can be used in the project.
As I just know - from what you wrote in your post - that the rpm must be at least 4000 - I searched and found a rotary encoder **HERE**
Could you please tell me if, in your opinion, his specifications are compatible with my objective?
