Hi there, this is awesome! I'm trying to make a clock for my wife that also uses the BKA 30D-R5 but stuck by the lack of footprint/symbols and my inexperience to create them from scratch. Could you share those with me? I saw the zip and it has everything else, but that. Thanks for reading me and for sharing project with the community.

Impressive write-up and explanation. Your content is well made.

جميل جدا لكن اريد معرفة الجزء العاطل في مقياس الخاص بي (vector vc9808) بسبب قياس مكثف10u مشحون 300v ..😢..الان يعطي قيم خاطئة L..c..هل يمكن إصلاحه ليعطي قيم صحيحة ؟

Great Explanation

After so many years, my question is whether I can order the board .LZ1INK.73

Thanks to Neil Hecht for sharing his project ,Very useful, nicely done video I've been looking for a good lc meter schematic for a long time, looks like I finally found it

Delphi - YES!!!!!!!!!!!!!!! Not a M$ drone, ....love it!!!!!!!!!!!!!!!!!!

I love this man ! Keep em comin' 👍

Thanks for yet another great project. It looks trully amazing. Would I be able to build one based on the files you posted ?

Yes, I get that the name of the channel is Designing HARDWARE, but it looks like a number of us are interested in your software development process as well. Do tell!

Some of the different things I like to get involved in are, computers, 3D printing, and woodworking. I think I am going to give this a try, about the only thing I do not have, is the aluminum L extrusions that you used here, but I "might" be able to work around not having that. I'm thinking I could build the entire enclosure using some 1/4 inch (apx. 6mm)thick acrylic. Great design!!!!!!!!!!!

OLD Skoo Geeza here... I too gould not beleive the price of 3.5" Caddies in this day and age (2022-2024) Wrong....! Just Wrong!!! Love this man!! Nothing like a hard copy to archive for yourself other than a clould service! The majority of this newer generation will laugh regarding this 'Back-Up' meathod. More fool them! Thank you for a great tutorial! Thank you for sharing to the people! X

Are the switch spacers and tops that you used available commercially? Or did you print them 3D?

Why did you use light pipes for the LEDs rather than leaving the LED leads long enough for the LED to reach the top of the case?

Your exclamations are very thorough and appreciated.🙏

I built 2 of these but have not gotten them to work yet. I am wondering if me not setting or picking any AVR fuse settings when I programmed the mcu would be the cause. Coreweaver what should those fuse settings be? Thank you.

Hey man I;m doing a similar project, would you mind sharing your firmware ? So that I can figure out what I'm doing wrong, thanks

power supply need 12v 2a?

Awesome!!!

Are you still working on new projects?

Hi! I don't have LM311. I was making a generator using the LM4580 operational amplifier, but the generator did not work. I made a transistor generator, everything works great! ruclips.net/video/JKyrUbSgpiQ/видео.htmlsi=sk0eRllXp6vxKnOM

That's awesome bro!! Very cool...I'm just gonna buy the adapter.

Did you think about using a 0 offset function? Would it help? I.E calibrate with leads both open and shorted

Does this reduce the noise ?

I have finished the hardware and have done a simple "Hello World". I am having a difficult time loading the Hex File firmware into the Processor. What did you used to load the firmware. Thanks

This is perfect for a project I have in mind. Thank you for sharing this!!!

Wonderful LC meter. A Very nice tool.

Yipiee!!!! Finally I find a digital alarm clock that can play "music" and with software that is written in Bascom-Avr!! Plenty of clocks I can find but all made with Arduino. I have problems understanding C++ and that is why I choose more then 25 years ago for Basic ..... and with the introduction of microcontrollers, I bought Bascom-Avr; a more simple language .... for me anyway. Thank you for posting this project to RUclips!!

Its only using nokia 3310 modul lcd

An absolute gem of an article, it also solved a similar issue I had with the need to retain a Bluray combo unit in upgrading to a modern desktop case that had no 5.25" bays. FUBAR! My need for multiple removable HDD's - I work with video and previously used an Icy Dock Caddy system - was economically solved with external 3.5" and 2.5" drive cases . . but an external case for an optical drive? GB£56 up to GB£93?!?!? Your DIY case is really rather pro finish but it's your mention of the UNITEK that has solved my problem because I didn't know this type of adapter was available and it will allow me to gut the circuit board out of the rear of an old alloy case for an EIDE drive and use that case! Perfect, the UNITEK has cost me GB£20, and I've "up-cycled" an old PC component too! Huge thanks!

is it necessary to build an enclosure for the player, for safety or anything?

Well done, great job, keep going

This is really awesome work, I'm working on a project like this and I was wondering if you could help me understand the firmware of for this project. I noticed that you are using the IO pins of the MCU for USB communication. Is there a specific way you're sending those commands or is there anything else?

Thats awesome was just searching cant believe the price. May just get that adapter and call it a day.

Cool build Earned a subscriber

To measure such small values of capacitors, the calibration MUST be done with the probes connected, and the leads dressed as they will be when taking the measurements! (also keep your hands clear of the probes while calibrating! This way the capacitance of the probe wires will be included when the calibration is done, and therefore the lead capacitance will be zeroed out. After the probe leads are attached to the capacitor being measured you must REMOVE your hands so that you won't be adding hand capacitance to the readings. Finally, what is the smallest values of inductance that can be measured? What about the largest values of L and C? Also there should be a way to calibrate the meter (actually ZERO the meter) for inductance. To do this, the probes would be shorted and a reading taken of the "zero" frequency for inductance. This way small inductors could be measured, and not include the inductance of the leads. Also relay 1 can be eliminated by using a DPDT switch to change between L and C. The ground pole of the switch will either ground the inductor or a port pin on the micro controller to let it know what mode it's in. To enter calibration mode would use a push button switch. Now separate calibration / zero routines can be done for L and C. This will allow for the L zero function mentioned above. The above ideas came from a meter by VK3BHR that used a PIC16F628 (which also has an LM311 equal inside it). I built his meter and it works well, but is limited to measuring C down to about 1pf, and L down to about .1 uh (it reads down to .01 pf and uh, but with +/- 0.01 resolution display it can't be considered accurate that low). The original AEE meter was able to read a lot lower and higher in C and L.

Why not just display the mode (L, C, or CAL) on the LCD instead of using the two LED's? Also, the atMega328 will run fine at 8 MHZ from a 3.3 volt supply, so there isn't any need to run it at 5 volts which would simplify the power supply. The relays might not work at 3.3 v, however I think that relays with a lower coil voltage are available, or they could be powered from before the 3.3 volt regulator.

Is there any way to contact you ? :)

Thanks to Neil Hecht for sharing his project ,Very useful, nicely done video I've been looking for a good lc meter schematic for a long time, looks like I finally found it

My mom is looking for a new clock and I was thinking of making one. Your has all the functionality that I need with the TEA5767 being something I have been wanting to play with and the icing on the cake is that display, it's beautiful. Thank you for making it open source.

Do you have any idea for m«building a dumbphone(mostly classic, flip, slider and qwerty)

Cool stuff. How did you implement the whole USB communication on this device? Did you use something like V-USB?

can this circuit measure 10nH inductor?!

I guess those nice measuring probes and cables you use are making a huge difference especially when you measure small caps and you wanna minimize the errors. I'll try buy the same ones for my LC Meter. Thanks for doing this follow up vid 👍👍

Great project. I could not find the part I am after which is how to measure the DC parameters of an inductor, something like: inductance, the DCR etc. However, I would be greatful if you could give me a hint how to project a meter for inductor DC parameters. Thank you.

Promo-SM 😇

I am using the google translator, so I apologize for any error, First of all, congratulate you for such a good project, I have the first version, check it out and it is similar, only that they use a PIC, but I like this version of yours better, I see it as more refined and Very good finish with enough precision, Of course it can be improved in Your hands, I am already subscribed to your channel from this moment waiting for a much better one, It will be a real pleasure to do it I, I would like, Since you work so excellent, to confuse it to do a Capacities and ESR Meter in a Single Equipment and that in turn gave the losses in the capacitor to be Measured. From already thank you very much for your time. I remain cordially yours. Luis .

This has to be one of the most underrated channels on youtube! Keep up the fabulous work!! :)

Hey, nice work 👍 I wonder which key you used for media volume increase and decrease. I was able to manage other keys, but not the multimedia keys.

Very cool
