A broken Arduino...

What should a dead arduino board be called?

Deaduino? Or are you now a Boreduino? lol yeah I'm majorly sleep deprived.

Mony Pythons dead parrot sketch could give some ideas :slight_smile:

An exArduino, or perhaps its not dead, just resting after a particularly long download .....

Hi, how did you deduce that it was broken?
Was it the fact that it was nailed to its shield?
Was it a copy arduino or the true Norwegian Blue Arduino?

Tom.... 8)

it was pushing up DC

Gone to Italy to meet its maker ?

I don't know any Italian, but in most latin based languages the word for "dead" or "death" is some variation of "mort", so maybe "Mortuino"?



It has shuffled off this mortal COIL!! Bwah ha ha hahahaha



While making yet another proto transmitter for a telemetry system ( the customer couldn't wait for me to have a pcb made ) I reckoned I would make it even thinner by doing away with the socket for the 328 chip, and make it thinner still than the first ones.

After all, the software works, so why should I want to remove the chip ?

I plugged in, and the PC said it didn't recognise the USB device, then I smelt that smell that comes before the magic smoke comes out ( I think the USB couldnt supply enough current for the full floorshow :slight_smile: )

I had marked pin 1 on the underside of the chip before I stuck it in deadbug style, but somehow got it mirror image :frowning:

So this chip is no more, its gone to meet its maker, its an ex 328, its shuffled off its mortal coil, and I am $3 out of pocket :frowning:

The chip's a 386?

As in an intel 386? (Tradionally square cpu?)

The long chip is the usual Atmega328 not a 386 of course ( sorry , been a day and a night on this )

The other module - the receiver is the nightmare of spaghetti wiring, But at least I put a socket on this one !

I have actually designed the pcbs for both ends but the customer cant wait, and there could be plenty of further orders ( they say .. yes well ... )

(FYI , this project I got a lot of help from the forum a year ago when it came to the parsing of the serial data from the PC, and sending it the receiver display unit .
The transmitter in the thin box has a usb/ttl converter connected to the rx & tx pins of the 328, and sends the parsed data via VirtualWire and a Hope RF link, to the receiver unit which displays the incoming data on six 7 segment displays via another 328 and MUX 7219 chip )

How are those RF modules working out for you? Some day I have a few projects I'd like to add wireless comms to, and I think the XBee stuff might be a little overkill. Think wireless NES / SNES controllers and stuff. Maybe 6-20ft typical. Those Hope thingies might be just the ticket.

The Hope modules are fine, I get 200m range with a 17cm wire antenna both ends, and they are very inexpensive ( less than $2 each )

Hope for a broken Arduino (just so this post isn't off topic !!)
i'm a newbie and got this cheap kit
and was wondering how it compares spec-wise to the Hope ones.
i bought them because they seem straight-forward to learn to use, 4 pins - one can't go wrong ??....

I think I have used those modules along the way, there are so many of them being made in China now.

I have tried quite a few ( mainly what was a available at the time ) and only had one bad batch - I don't knpw if it was this type though.

Remember these ones are simplex - one way data from transmitter to receiver, so there is no handshaking for checking if the message got through.

The VirtualWire library is simple, but excellent. I make scoreboards, and I send the first byte as an ID number so that I can have several remotes at the same school without interfering with each other.
The receiver ignores any data without the right ID number.
I also send the date 3 times, so as long as one gets through it works.

BTW some of the transmitters I played with transmit with no data going to them ( not very good if your neighbour is trying to open their garage door ) so I recommend taking the supply from the VirtualWire PTT pin, I do this anyway in my battery remotes and I also have an LED on this pin ( with a 4k7 resistor ) to flash when it transmits.

Good luck.

Brilliant -- thanks! 8)


Oh cool.... I was actually getting excited at the thought of a 386 awwwww!.

I'm almost finished wiring up a small project and more than 2 shift registers leads to spaghetti junction :fearful:
