Your Raspberry Pi Projects

I would like to build an arcade machine.
any tips?
Plan is:
builder's warehouse to do the wood work, get 2 arcade controllers, use my LCD 24" and run Piplay or RetroPie
 
Was wondering if it was possible to load up a RPI with an OS of some nature, to interface with an OBD2 port, via USB - touch screen displaying some chosen variables
It is basically to re-create another device which has gone out of production, developed originally in SA, called the Jax Dash
Shows you 15 Engine Control Unit readings. Popular ones are:
-- Air Intake Temperature
-- Boost
-- Knock Correction
-- Fine Learn Knock Correction
-- Ignition Advance Multiplier
-- Water Temperature
-- Engine Load(calculated)
-- Mass Airflow
-- Air fuel ratio
-- Fuel consumption

I got a sample Python script to test and it works fine. Commands are sent and responses received. There's a USB-to-serial cable, to the port is /dev/ttyUSB0 - address it the same way as you would address a serial port, i.e. /dev/serial0

ooohh, share some code!

and ............. another question.

Do you guys do these projects on a plain, simple Raspberry Pi?

A friend says he'd like to do a bit of programming/exploring but he needs something more than just the Pi. What would he need apart from a monitor, keyboard and mouse?

...........or am I being played :D

A plain, simple Raspberry Pi includes Wifi, bluetooth, CPU, RAM etc. All you need is a power supply ( a phone charger), and a memory card to install the OS onto. And optionally a keyboard, mouse and monitor/tv.

Like this:

or this?

It's on my todo-list as well. But Torque, on Android works so well already ;) It cost only R53!

Thank you for this K3NS31

This looks like what you're asking for:

Any recommendations to do a hot clone of the SD card, running one of the linux variations, remotely?

To make it more complicated:
- without using dd
- doing it remotely from a windows platform (hence the dd limitation for restore purposes)
- possibly scheduling it to clone every x days


Currently using dd to backup up core configs and in the eventual case of having to do a restore, I'm formatting SD cards, reinstalling whichever linux flavour and restoring the configs, manually. Takes quite a bit of time if you play around with different setups.

Check Clonezilla? Won't run from Windoze tho. Acronis maybe?

I don't think either can meet the two requirements:
(1) Hot
(2) Remotely

If I were to do this on a Mac, it would be somewhat possible using Time Machine, which does one massive backup then does incrementals as time passes. I found these two solutions and without reading the detail (MrR can do that) they might provide the solution:

The latter certainly looks promising.

I"m sure you could make Clonezilla do it. What about an RSYNC based solution? Oh wait, just checked your second link. Great minds, LOL

LOL

From my (limited) exposure to Clonezilla, it has its own boot disk (image) and its own GUI, which eliminates (2) Remotely.

Nah, it can do networked imaging as well, and since your target OS is Linux, I would imagine it might work "hot".

Oh, OK, cool. Like I said - haven't been that exposed to it (recently) so I have learnt something new. Does it still us dd to image?

Haven't used it for a while myself, but I remember it had several imaging options and DD was just one of them.

My recollection as well - so I checked the site. I don't know what this means...

"For unsupported file system, sector-to-sector copy is done by dd in Clonezilla."

So maybe dd is only used in those circumstances or when requested.



I have another Pi question. So, we have a system where we keep an eye on a webpage that brings up system alerts. It is intended that a Pi will get these results from another server and refresh them all the time on a TV. The problem is, the damn Pi sleeps its display after about 30 minutes or so. Any idea how to stop that?
