Reinstall bootloader of Arduino

I use a AVRISP mkII for programming my arduino with eclipse. All fine but after first upload with avrdude, I also removed the arduino bootloader.

The bootloader can be restored. Typical (mint linux / debian) folder is:
/usr/share/arduino/hardware/arduino/bootloaders/optiboot

Just start avrdude with:
avrdude -c avrispmkII -p atmega328p -U flash:w:optiboot_atmega328.hex:a

Remove the USB cable and plug it in ... arduino should be programmable with the ardunino app.







Firefox - Resize of Tab text height by CSS? Really??

I found a way to change the height of the tab text of firefox. Check both screenshots to see the difference. If necessary, create a ~/.mozilla/firefox/BLABLABLA.default/"chrome" folder and create the userChrome.css with this code:

:root {
--tab-min-height: 15px !important;
}

Kickstarter: LED Lighting with NeoPixel 16 and ATmega32u4 / Pico

Tests with Pico. Works fine with the Arduino development tool. Just use the "Arduino Leonardo" Board for flashing.

TASCAM DR-05 Version 2.50

The TASCAM DR-05 recorder got a new software update. Ok, the german language is a little bit confusing for english-tech-speaking users but hey ... I used 2.1 before and this seems to be a good idea.

Just one note: Not sure why but step 7 did not work for me. I pressed MARK, BACKWARDS AND(!) POWER_ON. After this, the start screen changed and the update was avaiable in the list by pressing "play". Never mind.
