you have to see frist what your caliper can measure and how far... some can measure up to 650mm or 25mm or 1000mm and then there's a zero...

Did you mean jlcpcb? Is it still possible to order them from there?

not all calipers have a data output..in 24 bit mode

@@diyjaki8628 This was- going by the clock bits.

I have recently bought a couple of the cheapest plastic calipers I could find on eBay and the data out on these are working ok but I was surprised to discover it reads in 100th mm despite the calipers only displaying 10ths.

Datinf Measure for the measure

should be possible 2000 mm but most calipers only count up to 650 mm so needs some specific arduino code

@@jimi1233 Hi, The 0,01 accurate calipers continue the count until 999,99 mm then to 0, so it's easy to code. One question: in your video, between 09:11 and 09:14 you don't show how you 'glue' them together, I think I need to solder and verify the exact distance between 2 pieces? ALmost done here, will share the video. Combined with a rotary encoder, I have accuracy up to 0,0001 mm (0,1 micron)

@@JohanDegraeveAanscharius Hi Johan, I'm working to make it 2000mm too, what did you change to the code? how did you do the distance between 2 pieces?

@@jimi1233 Hi, they still have problems with this. The layers don't correspond with their system. Tried 10 times, nogo.

@@jimi1233 There seems to be a problem with the Gerber files. They say that there's no trace in the file and therefore no copper layer.

@@TheThelama53 have you try from this new design ...www.pcbway.com/project/shareproject/Digital_Caliper_Hack_Mod_new_2021.html

@@TheThelama53 they need to zoom in on the gerber file really far. The traces are there.

@@romixlee6643 that's true for me it was audit failed too because they are too blind to zoom in to the gerber haha

yes the Engineer are confused anytime but i change the design now should be posible to order...

@@jimi1233 They are. Got order by ordering single layer and minus all else. Received - all works. Many thanks !

Hello the finish PCB and all dimensions is on www.pcbway.com/project/shareproject/Digital_Caliper_HACK_MOD_from_150mm_to_650mm.html you need only to export it as gerber file ..

the most important thing is the distances 0.1 inch =2,54mm Everything else is not so important here the dimensions ibb.co/wWk44FW

i had tried a year ago to decrypt the code after 3 attempts I got the right results +0.01 -0.01 if the board gaps do not fit the tolerance is 3mm or more Only a high quality pcb manufacturer can produce the printed circuit boards

@@jimi1233 The board itself, the one in the caliper, of course must be made very accurately. Accuracy depends on it. But the requirements for the accuracy of the ruler are much lower. I made a ruler tape on a simple CNC milling machine, I simply engraved with a milling cutter without even taking into account the width between the platforms. And everything works exactly. In the descriptions for this video there is a .cdr file, there is a drawn ruler that I milled. th-cam.com/video/ru7R1dLsWgY/w-d-xo.html Сама плата, та что в штангенциркуле, естественно должна быть выполненна очень точно. От нее и зависит точность. Но требования к точности линейки гораздо ниже. Я ленту линейки делал на простом фрезерном станке CNC, просто гравировал фрезой даже не учитывая ширину между площадками. И всё работает точно. В описаниях к этому видео есть файл .cdr, там отрисована линейка которую я фрезеровал. th-cam.com/video/ru7R1dLsWgY/w-d-xo.html

Hello try this "U8GLIB_SSD1306_128X64 u8g(10, 9); // HW SPI Com" i have test it with Nokia display before and the I2C mode is on Atmega328P pin A4=(SDA) And A5=(SCL) ...i hope it can help

@@jimi1233 Thanks for the response, I have sorted out the problem. The sda and scl pins needed pull up resistors to 5 volts. Doing that the display doesn't freeze anymore. Also with the pinchangeinterrupt version 1.3 the sketch compiles without error. And everything works as intended. Thanks again for the great project. Keep up the good work.

hello valdemar next time i will change the firmware and add tachometer but you can use the another firmware th-cam.com/video/F3HP7osizsc/w-d-xo.html

Hallo @@jimi1233 th-cam.com/video/F3HP7osizsc/w-d-xo.html »»»»For this firmware I need to do another board ,It’s not a problem for me to make a new board, but when I didn’t work with this file extension , (promini-caliper-bloodhod.brd ;promini-caliper-bloodhod.sch)and I don’t know in which program to open them, to see the circuit and the circuit board of the board, I only worked with such a program (Sprint-Layout), but this program does not understand your files. Please tell me, but on the new board with the display there is already an outlet for connecting the tacho, it can be implemented somehow, and it would be better if you showed it all on the video, how to do it, thanks for your work.I live in Hamburg if I could talk to you somehow, if you speak German😊

@@jimi1233 Thank you, I already guessed, there is one minus that when connecting bluetooth to the display, not all functions work, you can’t reset the axes, it would be better if the bluetooth and display worked together without a button, but everything turned out cool thanks for your efforts, and even It would not be bad to create one, so that it would be possible to do on and off the axes on the display and add a tachometer
