    if your going from AVR to Pi or STM32, remember your i/o is 3.3v
    good for displays - you dont need resistors,zeners or buffers anymore - but may need a bit of attention with some sensors

      I've had two Arduino Due's ... and managed to foul them up pretty nicely because i wasn't being mindful of the 3v limit. However, these Teensy 4.0's I've managed to not damage and they are 3v so ... this old dog can learn some new tricks.

        Are Microchip/General Instruments PIC8s dead yet?
        If so, good riddance.
        If not, ()#$*#(@#*(@ their memory management.

          Could you have meant the PIC18 Microcontroller?

            No, I generalized all PIC 8-bit microcontrollers into the same bin... the trash bin...

              That's where my Commodore 64 went several decades ago and I still don't regret it ... even if these weirdos are obsessed with the C=64 making a come back... I don't live for the past ... I'm happy to be done with it.

                Never used a C64 but as a 6502 I don't think that's horribly bad. I do have my qualms with 6502 however, not a great processor either but much better than PIC 8-bit...

                6502s are fast however. Beats the Z80 which I've preferred, but 6502s murder the Z80 MHz for MHz.

                  This new laptop I got has 32 gigs of RAM in it...

                  My first computer, the C=64 had 64k of ram...

                  So TODAY, my computer has 500,000 times more ram than my first one.

                  That's pretty phenomenal to me.

                    Logitech G29 Help request to find smd transistor reference.
                    by nunofcc
                    Good night,
                    I am going to ask your help to find out what is the reference of this smd transistor. Or what is an equivalent transistor?

                    Thank you for your help....

                    Where to find a very small fpc connector 0.3mm between 2 pins ?
                    by corrize
                    Hello, I search this connector (oxydated).
                    It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
                    I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
                    I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?


                    Do you know how to find this connector please ? What is the exact name for find it ?

                    Where can I find a DD3 128000 type memory but 32 MGB in one module because this laptop has only one slot
                    by sam_sam_sam
                    This Dell computer is a pain in the a** because of it only has one memory slot this computer only had 4 megabytes of memory and slower than shit I found a 8 megabyte memory module and it is better but still slow as shit the maximum is 32 megabytes of RAM but I was not able to find one I found some that are 16 megabytes but they are 1600/128000 type and I am not sure if this computer will work with this type of memory or not

                    Dose anyone knows where I can find a 32 megabytes memory module for this computer because the battery still works fairly well still I would like to use it on my...

                    Behringer Eurolive B205D repair - help identifying transistor
                    by magneh
                    Hello
                    Got this speaker from a friend , defective. Power led comes on and off , in a loop.
                    Disassembled, got the board out, and after a bit of measuring I found a low resistance on a 5v6 line. With a bit of current I found a transistor heating up on that line (labeled T1 and 113 as on pic).
                    After removing this guy, I got a value of 0.7 in diode mode on that 5v6 line, which before had 0.02 or something like that.

                    I tested powering it up without the IC, and the speaker turns on and stays on, and works fine

                    Still, I need to replace this transistor....
