Micronucleus bootloader for ATTiny85

- Each week I will grab a random electronic component from the vault and build a circuit - this week I look at a so-called programming board for ATTiny85 - not as it seems!

I never plug mine attiny13 in that board buy I was tempted at first. I new it was for the 85 version.
I have 3 types of Attiny85 but No 8pin chips yet. I was thinking about buying 2 for the 2 boards I have.
Glad you told me that the 13 blow up. Lol I want to program them with the Arduino I order more chip recently. I think I like to collect Microcontrollers at this point.
Yes it is funny how many microcontrollers one person needs! 🤷🏻
Any chance at helping me out? I've unpacked the zip, navigated through and used the make command as you did. but when i try micronucleus --run i get an ssh error command not found. Must have missed a step no?
What OS are you using, what version of t85 are you trying to connect to and can you see it on your devices list?
I'm not sure if this information is useful or not, as I did'nt understand a word of it. LOL.
I've found there is too much terminology that you are expected to know about, But people new to these chips don't understand it. I've looked at forums and YT clips, but they make the same assumptions.
The ATTiny85 you showed on the breadboard are the ones I (try to) use.
Yeah agreed. I’d give the whole micronucleus path a miss. Too complicated for too little “reward”!
I have a blue color digistump clone with firmware version 1.6 . ( the type you show at 8:46 )
I followed exactly same steps like you did (micronucleus 2.5) and I got same output in terminal when I "../commandline/micronucleus --run upgrades/upgrade-t85_default.hex" .
Then I tried within arduino to upload a sketch , plugged in board , and it does not connect by "ATTinyCore/tools/micronucleus/2.5-azd1b/micronucleus --no-ansi --run --timeout 60 /tmp/arduino_build_169828/ATtiny85-note-play.ino.hex" .
I don't have any more idea what to do . I can't replicate steps because the attiny85 is not connecting anymore . I don't have a hi voltage programmer also .
I can't find the firmware 1.6 so I can't flash back with avrdude . I found only micronucleus 1.11 .
I tried avrdude flash with upgrade-t85_default.hex ( fuses correct for enable reset P5 pin) , but even that didn't worked out .
From memory if you’ve enabled the reset pin then the ATTiny85 can no longer be programmed. You’ll need a high voltage programmer to unbrick it. I use a commercial one (as shown on the video), but you can easily make your own with a few simple components. See for example: arduinodiy.wordpress.com/2015/05/16/high-voltage-programmingunbricking-for-attiny/
Good luck and please let me know how you get on. 👍😀
I have a programming shied for my Arduino but it just haves a ziff socket instead of different size headers
Commercial or home grown? Does it take 8 pin, 14 pin, etc without reconfiguration? 🤔
@@onecircuit-as yes it's commercial and needs no configuration, also it has a socket that takes up to 28 pins
It looks like this one

Oh yes I have used those (ruclips.net/video/SSGx4kkKa20/видео.html). Just never tried them with the 8pin ATTiny chips on the assumption that the VCC and GND pins would misalign.
