@Samuel235 It would be possible, I am planning to implement a GPS, and wireless information would be really nice, 'Hi! I'm stuck at XXXX' :)
There is a small problem though, not enough IO's, so we probobly need to hack and add one more CPU (atmega? ;) that uses the 8 io to the keypad and send data serially between the cpu's (decoding keypad in atmega, send seriell, and tada 7 free io's! :) Plenty enough for wireless chips!
regarding GPS I think I can use the built in USB in the battery compartment, no major mod required for it. :)
For more IO you could use an I2C based I/O extender chip.
There is also MCP23017 (also available in DIL format) which is a 16-Bit I/O Expander with Serial Interface (exists in SPI and I2C versions). This gives an atmega328 an extra 16 digital pins with just SDA and SCL !PCA9685 is also an I2C driven expander which has 16 channels which can be used for PWM (driving servo's) or as normal digital Input or Output pins. Each channel can be set in it's own way, independent from the other channels. There is no DIL version of this chip, but a breakout exists on Aliexpres (quite cheap).
So there are some options if an extra cpu is not desirable.

@Damme, there is also the 74HC238 IC too. I was doing some educational reading this morning and stumbled across this little fella for some reason while looking at 555 timers. I just remembered what it was when Gert mentioned the use of his suggested ICs. However it is only a 3-8 IO decoder.

Hello everyone!
It's fun seeing this thread alive again!
Sorry I havn't been here for a long while, in the picture you'll see what have been keeping me occupied.. (the orange lawn mower, I'm reverse-engineering it!) and I also moved over from Arduino, atmega328p to esp8266 devices and more advanced cpu's (arm, cortex etc) and 'real' build enviroments..
If there is any interest in my project, https://hackaday.io/project/6717-landlord
The picture pretty much explains how my brain works.. I really need to clean up, might add another picture after that. Behind the mower two rigol devices are hiding, a scope and a p-psu.

And in full swing of prototyping, as promissed:
-
@Matt, i generally keep my chainsaw downstairs away from my electronics. I can't have the oil everywhere!
@Samuel235 yeah the Dolmar leaks, I think its a design feature. Problem is I live with three drunken monkeys who are entropy impersonated, as such I cant keep anything inside if I want to find it again.

I am especially proud of my 20 years old analog soldering station. :D

my 20 years old analog soldering station
I have the exact same one! :+1:
However, it's not in use anymore :flushed:

I just bought a new soldering iron for it last year. Had to google for days to find spare parts. :D

@gohan That looks very much like the one that @AWI posted previously in the thread only with a nice case and a color display. The one he posted is quite a bit cheaper. I may get one myself and just 3D print a case for it. I can use your link for the 3D case design.

Just looked on ebay, and here is one a bit cheaper that comes with a basic case.

if you want the case it costs 10$. The one I posted it seems to have pretty much the same specs, but it can detect also IR and probably some more components. It also comes with a lithium battery instead of the classic 9V, color screen and the case looks much better :)

@gohan You are right. I just ordered the thing. With the case and the builtin battery it looks like a real tool. The price seems to be a promotion. Normal price is >30$.
You shoult by the way fix the link. Makes it easier for others to order it.I am looking for a soldering vise. Has anyone tested this one: https://www.amazon.de/dp/B00196RV9C/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&colid=2COJS1QZ6SUVJ&coliid=IQEGMI1GM2R46 ?
