true!

@@ProDroneControl I will try to reproduce your experiments with LC tank to see if there is a potential for an L meter using microcontroller.

@@odissey2 that's quite possible. Ages ago, i did that with atmega328. All you need to do is make a frequency counter using uC. I used bare minimum code with OP codes to directly access timers and reduce code latency. Once frequency is measured, we use lc tank formula to get back inductor value. It was pretty accurate in nH to mH range.. in uHenry range, all parasitic components play nasty role nd measurements get weird.

Same as the other discrete components provided...to show user the tester works on various parts, to help neophyte users gain some experience on using the ZIF socket (Zero Insertion Force).

Glad I could help! 👍

Fixed it with GOWIN IDE

Are you sure that your usb device is working fine?!

Win 11 here sir.

were you getting this error ?Error: Failed to claim FPGA device: mismatch between target's idcode and bitstream idcode, do you know anything about it?

I ditched this for a cyclone dev board, i couldn't use that through USB no matter what guides I followed. I ordered USB blaster, it arrive, sat in a box. Never went back. FPGA is a steep learning curve and I have regular MCU projects onboard for now. I will try again in future with FPGA, but it will be the cyclone @@powerHungryMOSFET

@@LionelSanderson I did setup with GOWIN IDE and Programmer, with which I am able to work on Tang Nano. It was issue with the drivers which GOWIN IDE fixed it. Thanks for the response

That's the way you go if you wanna throw the air outta that blow outlet ! 👍

@@ProDroneControl: The air will only go out that hole with either direction that you spin the fan, as a centrifugal fan. It will just blow a lot harder when you spin this kind of centrifugal fan in the convex direction, because it puts enough less load on the motor for the amount of power you're giving it, and thus the motor can actually spin at enough of a faster speed that's more than just making up for the lesser amount of air being picked up at a time by each blade for being spun away from their concave direction instead of towards it. If the fan were a "squirrel cage" type of centrifugal fan instead, then by design you would spin it in the concave direction comma and it wouldn't give you as high a pressure as this one would if you spun it correctly, but it would give you more flow at a time. I don't really know how to explain the difference between pressure and flow rate when the size of the housing isn't adjusted to match one or the other.

​@@HelloKittyFanMan I wanted more air somehow with this little blower and found this way effective. Any more tips on how to improve this are most welcome!

@@ProDroneControl: You would have made this more effective with the blades spinning in the other direction, not only for the reason that I just stated, but also because they would be throwing the are directly towards the outlet rather than just into the circular area again. Also, these are normally in more of a spiral shape with the blower blades and intake on the inside of the spiral than they are like this ( basically your circle with that straight area coming out of it). I can't explain why the spiral is supposed to work better, but it does.

Thank you, I will!

Thanks for watching!

No price. If you have 3D printer, I have provided files to download and make your own !

yes through vscode.. zadig is just for helping out in drivers installation. After drivers are successfully installed, it isn't required aymore.

@@ProDroneControl Can you use VHDL this way?

I have worked with only 3.3v levels. Not sure if they are 5v tolerant !! Never tested!

Thast true.. Unlike other popular languages Verilog is not so common, probably because small portable fpga boards are not common for a common user! Nowadays, things changing and resources improving.. This board is very handy and can help make hardware for the projects that need high speed realtime processing. To learn verilog, I would say RU-vid but it again comes back to how much you practice and get involved with fpga based projects.

I'm a bit late to the party, but I found this one useful: www.isy.liu.se/edu/kurs/TSEA83/kursmaterial/vhdl/free_range_vhdl_2019.pdf when I started out, but there are a few resources out there. I use VHDL rather than Verilog, but the basic idea is the same, although the language is different. (Don't try to use both - at least not at first, or you'll go mad. Once you're proficient in one, then you can have a go at another. ) Either way, the important thing is not nearly so much what happens (of course, this matters!) but WHEN it happens. The idea of processes, and the fact that nothing has a value until the end of that process is vitally important. This means that if you are operating on two or more signals, most of your errors will be around signals that don't line up in time. You will need to learn to love (and trust!) your simulator, because that's the ONLY way you're going to make sense of things. Oh - and line endings.VHDL uses ; as a line terminator, but again, a lot of early errors will be due to that dreaded semicolon.. Particularly with VHDL (partly because it's so verbose) it's very helpful to find, and use, a very open style of code - put in lots of comments, and try to have only one operation or function per process. It's perfectly possible to write really tight, dense code. And it's unreadable. Don't do that.. Use sub blocks too. keep everything simple, clear and well laid out. This will help you find errors, and (if you ever start looking for a job coding HDL) looks much more impressive than dense ugly code. I know which I'd rather work with.. Use, but beware of, opencores.org - it's an excellent resource, but quite a lot of the code doesn't;t work as advertised. It's often instructive to view things, but it's very rarely a copy and paste job - you do need to think about what you're doing. Some stuff works, but if you're use to pasting Java snippets, you're headed for a nasty shock there.. Caveat emptor. There's a link here: www.linuxlinks.com/excellent-free-books-learn-vhdl/ to some other free VHDL books. If you want videos, check out NANDLAND, as he has some good stuff, and for the more advanced class and inspiration, check out Whitney Knitter at Knitronics. If you aspire to be any good, you'll need a copy of Peter Ashenden's book, to really get under the skin of things, but frankly it's about as inspiring as a telephone book. It's vital, you need it, but damm it's boring - it's reference, not tutorial. The climb to mastery is long, and very frustrating, but well worth it. Check out the forums too - but a word to the wise - ALWAYS explain what you have already done, and what you tried to fix things but that that didn't work. FPGA forums can be very helpful, but ONLY if you evidence you've already tried - otherwise everyone will assume you're a college student trying to get someone else to do your work. They will then ignore you. Oh - and you'll often get job offers. VHDL engineers are rare, and anyone with a pulse gets job offers. Good luck, and keep plugging away - the rewards are well worth it. FPGA programming. Like everyone else, but faster. A LOT faster..

Use some usb or Bluetooth keyboard. But those keyboards don't have wifi on, off buttion. So this tutorial deals with that problem.

Thanks sir!

Glad it helped! Thanks!
