I recently purchased a SLC Free (B) kit from 14point7 and have just finished assembling it, so I thought I would post some pictures etc since when I was looking there was not a lot of info about it (apart from this thread). I will start by saying I'm really a mechanical engineer but also do a fair bit of aftermarket EFI installation & tuning so only have basic electronics skills, having said that I found it was a really nice complete kit with everything well labelled so it went together easy. Pretty impressive kit for $45 - I've seen just the bosch lambda connector alone selling for $20 on ebay. I already have a good Motec PLM wideband, but this will just be my backup and something that I am more happy to lend out to customers or use on a road test etc...
So here's what you get in the kit:

Main PCB assembled:


To make it a little more professional, I machined up an alloy case (motec style), added some $3 chinese 'mil spec' connectors and just to keep the DIY haters guessing I machined a Pectel logo on to the front:


A pic of it powered up - note the display is perfectly clear in real life - its just my camera doesnt like the backlight in this photo:


Still waiting for my six core cable to arrive before I can attach a probe and comment on its performance but I'm sure it will be good. In the open source spirit I will pass on to 14point7 the model files for the enclosure that I designed as you could probably 3D print it fairly cost effectively.

Love the neat box, love the pectel humour, and love the open source spirit! Thanks for posting this up :-)

Im on board, Ill buy the deluxe with O2 sensor. wish someone could make me a cool housing...hint hint!

Jesus that is a nice looking case

Nice case, the project files you have could be used in a CNC machine?

CNC code own it's own is pretty worthless since it needs to be taylored to the specifics of the job and the machine doing the cutting - The code would need to be changed depending on how big your 'stock' is and many other things like the size of the cutter and the speeds/feeds that the machine can do etc.
So the attached 3D models are just generic .stl files so they can be used with many methods of manufacture. I have access to a CNC mill and wanted it to look nice so thats what I used but I suspect in the DIY community methods such as 3D printing or CNC router would be more popular since they are low cost.
I have left the holes for the connectors out of the model so that it gives the builder the option to use whatever type of connectors they choose - even the default SLC free molex connectors will fit in and and work reasonably well. You can use Google sketch up to open and modify the 3D model however you like.

I appreciate it very much.

When I make mine, I will post photos here.

WOW.

I've request a price quote for a high detailed 3d printing, and it will probably be cheaper if I chose the CNC option.



It's almost 250 usd.
