could the projectile be replaced with magnetic fluid in a circular tube?

when I open ardino IDE, it says that no port was found. Although, I installed the driver libusbK for the programmer. By the way, my programmer has one more jumper, one is for swapping between 3,3 and 5 V (JP21), and the other one - I have no idea what it does (jp1). Also, I have two more holes for another jumper, jp3. PLUS: I once burned a bootloader on the smd chip using an arduino nano. The bootloader remains on the chip? When I try to upload the blink code, an error occurs (Failed chip erase: uploading error: exit status 1) + "Double check connections and try again, or use -F to override this check."

Finally i've made a functional PCB for isp programming my core stock, thank you !

Great project , can you share your email address?

Hey, nice job coming from an Aussie maker in the midst of a similar project! Of course I stumble across this video after I finish designing my circuit 🙃. I have two questions: how did you find was the easiest way to wind the coils and connect them to the circuit, and did you ever measure their inductance? Yours are very neat and compact compared to the jumbled mess I'm currently working with...

You have very few videos but what you have are very good. One such video that i am sire you could add woul be the wiring of a Oled screen and a ATMEGA328P-AU in SPI mode. I have been trying to get this done. But my main issue is that the pins to use are different from the likes of a Arduino Nano. I would really like you to cover this topic.

Great 👍

Is it possible to work on ATmega uno?

Why burn the bootloader? You're wasting 1.5 seconds of boot time that the bootloader takes to boot the chip. Instead burn the HEX file directly to the chip, your chip will start the firmware immediately super fast.

thank you, sir. it's working perfectly.

Very useful video, thank you. Do u have another one, how to make a board with the Atmega328 chip - i mean what it needs to standalone?

if you connect the programmer on chip direct on pcb with the same way like yours is there problem ? or you must desolder the ic and follow the process that you show us

atmega328pb please

Could you use arduino nano to burn a bootloader to a chip?

Hi, nice project, well done!. Hm seems YT deleted my previous comment..... I woudl iket to add two leds, green, when price increasing green turns on, when decreasing red turns on. Is there any workaround to do this? Also, a wifi management would be nice, so if you want to chnage the wifi data, you wont have to rebuild the whole stuff..

Can you use this adapter if my microcontroller has no leads?

Atmega 8a program has restart problem in any type sparking in wire they have distrub a program

Great video. What's the white PCB you have connected to the breadboard with Vin and USB?

If i were to recreate your schematic with 6 stages, each using 1 capacitor of the same statistics as the ones you used, what would the results look like?

I have made a a PCB using this chip and for reset i have already put a switch between ground and 10K resistor with 5V supply so do i need to press it while uploading

thank u for the video it really helped

Very cool video. Too bad you stopped long time ago making them.

Thank you for an impressive, well-made video Sir!🌞

Is overbuilding, dude

Is it possible to program any ".hex" file using this? I don't know about Arduino, is it possible to load a hex file and then upload it?

Excelente.

Thank you sir! You heldped me a lot!

I've never been so excited to see a flashing LED before, thank you.

Hi where did you buy steel ball ? Maybe do you have a link? I can not find a pure steel ball.

Nice video. Thanks. I have a spl scenario. On my usb asp the main chip is damaged and i gavevspare atmega8a . I can solder it . But i wascunable to load the ubadp firmware into it wuthbusb access . Ppeadecsuggestva practicabe way. Thanks Regards Sarma vu3zmv

This is the best video I could have found

is there a smaller micro that can be used for the UPDI Programmer?

Thank you, this worked very well and the newest version of the usbASP driver works great too. This was the only video I watched and yet it was the only one I needed. Thank you again, this shit was epic.

Thank you.

@KakushinAU , in the same way I tried using Arduino Uno for ATtiuny402 but I got following errors, kindly help. Sketch uses 382 bytes (9%) of program storage space. Maximum is 4096 bytes.

Beautiful explanation. Thank you sir for the great tutorial. It worked the first time. It's fantastic. I didn't know what to do until I found your video. I have an Atmega 4809, but it's actually the same. Keep going.

Beyond loading sketches, can this UPDI Programmer be used to set fuses and Lock bits? I have a need to lock an Arduino Nano Every but don't have access via AVRDUDESS.

Çok iyi , mükemmel.

Great, clear concise, well explained and easy to follow. Thanks for taking the time and effort to produce the video :)

is the 19uf capcitor's value critical? If it's much larger say 100uF (which I have) will that work? Thanks for a great vid

Thanks for a clear explanation of this. I used the microupdi board you mention towards the end of your vid, and whilst it worked initially, my pro micro board is no longer recognised by the Arduino IDE, so can't upload the firmware. More research req'd :) :)

Thank you for this very informative video!!!!!!

kakushin, buenas noches, quiero agradecerle por la informacion suministrada, me sirvio muchisimo, excelente video. Saludos.

thank you for this video ☺

Hi. This is a very good video, however i`m not sure which chips i can use. I`ve got a lot on my Mini and Migthy Core boards but none with the PU or AU at the end. Just ATMega328 etc. Will any of these work in my project?

Are you powering the atmega and the programmer from the power supply? Or are you setting the programmer to output current?

Can you use serial to upload code to it after bootloader is burned?

Thank you for this informative Video. Well explained. Merci!

Great video! It helps a lot and ist well done. Thank you very much!
