Prusa i3 the leader among the non professional 3D printers is in stock

CI2A6664

Few months ago I was interested to try how 3D printers work. I googled a bit and I found thousands of variations online.

Even there is site which compare them here: http://www.3ders.org/pricecompare/3dprinters/

As I just wanted to play a bit making frames for our LCDs and Box prototypes for OLinuXino and had no intention to do any production with this printer I wanted to get something as cheap as possible so even if I break it during the assembly to not regret much.

I check all these super duper $140-300 range printers trying to order online and found that all of them are either “out of stock” either “give me the money upfront” and wait XX months until I attempt to produce it either my printer is $300 but shipping to Bulgaria is $400 so none of these was acceptable.

I soon realized most of these sub $300 were just vapour-ware and if you really want to buy something in stock it goes close to $700-800.

Finally I found Jelwek in Poland, which was accepting Paypal, I selected the medium printer they have and cost EUR 475 + shipping to Bulgaria by courier (which I found is normal post later) EUR 25 and ordered one. After about a month the kit arrived by post.

There are lot of documents how to assembly Prusa i3 on the net. For Jelwek this is shown here: https://www.flickr.com/photos/105048182@N02/sets/72157642944311244/

When the kit arrived I was a bit disappointed, the quality of the used parts was a bit low, three of the steppers were second hand, disassembled from old machines which was seen from the scratches and the cable cuts just the one for the extruder was new one.

All rods and shafts were cut by hand with not clean cuts and with lot of whiskers on the edges. Anyway when assembled the printer ran without problems, I already blogged about it here.

Many friends asked me about this printer after I blogged – they wanted also something cheap to start with 3D printing, so I asked our Chinese agent to try to locate low cost Prusa i3 clone and he sent me sample.
The kit arrived and here how it looks:

It’s seen that these kits are done by professional manufacturer – all motors are new and the shafts are directly coupled, you even get tools necessary for the assembly of mechanics like cutters, heat-resistant Kapton tape etc. which I had to supply additionally for the Polish kit I got first. The PCB is also all-in-one with integrated Arduino and drivers on same PCB. There is fan to cool the material exiting the extruder.
So after we inspected everything we decided to stock it, here how it looks assembled:

Now these kits are in our stock.

Note these are not assembled and require knowledge both in mechanics and electronics to make them work. Sure the final result is worth the efforts, it’s a great pleasure to see something working which you built with your own hands :)

PlovDev conference is tomorrow

Do not forget tomorrow starts PlovDev conference!

Looking forward to see you there :)

A80s Octa Core Allwinner SOCs – they finally arrived!

а80

Allwinner surprised us nicely while we have been at Linux Con they sent us 10 samples of their super duper new A80 Octa core processor.

I hate when Marketing in some companies start mixing dreams with realities and announce chips while they even are not in the pipeline :)

Allwinner announced this chip in February, then promised samples to be shipped in May, June, August, September, well they finally sent 10 in October :)

The reason we still do not see mass production of devices with A80 can be guess after reading CNX-Software blog . The firmware performance is still far away from stable and exploiting all features this chip can offer.

From Allwinner were kind enough to send some samples to Linux-Sunxi community.

We are almost complete with our A80 design so soon we will have more update.

Linux Con Europe 2014

LINUX-CON1

I’m just back in office from Linux Con Europe. For these who do wonder why last week there was no Weekend Challenge and Friday Giveaway Quiz – we, 5 people had to fly to Germany.

This year Linux Conference Europe, Embedded Linux Conference Europe, Cloud Open were held together in Duesseldorf Germany.
We at OLIMEX decided that we learned so much from Linux community in the last two years around OLinuXino that we should give back what we can and become Bronze sponsor was our way to say “Thanks” to Linus and Co. about the great work they do!

It’s nice to see your name among other companies which support Linux:

SPONSORS

sure we are still small and barely seen hehe :)

OLIMEX

For these who never have been on Linux Con, its a smaller than FOSDEM for instance. I guess because the entry ticket for the conference is $600 while FOSDEM is free and attracts more students, Linux Con is more Corporate oriented.

What you can see here is Intel, Samsung, Freescale, Texas Instruments, Mediatek, Red Hat and many others of the big companies which support Linux development.

You can make *very* useful contacts there.

For instance these two guys are Rockchip and Mediatek Linux Kernel maintainers:

rockmedia

We finally met there a developer who is working on Texas Instruments Sitara SDK, which we desperately trying to approach with our AM3352 board Linux problems, so we may finally solve all remaining issues ( I will blog more for this later!).

Also we got contacts with Qualcomm/Artheros and Mediatek Home Entertainment unit … soooo maybe in near future we will have 64 bit OSHW ARM development board for mortals, crossing fingers this to be sooner :))

As being sponsors we got table to present our OSHW Linux computer boards:

Around our table most of the time there was crowd starting from 8.00

even during the lunch time:

table-2

here we got visitors from Google interested in OLinuXino for their University Program:

Sure Linux Con had tons of interesting talks, thanks to Linux-Sunxi community now Allwinner chips are well recognized, there were several lectures about what Linux-Sunxi did in the past year:

Overall Linux Con is great event worth visiting, where else you can see Linus Torvald passing by you few meters away and even taking picture next to him ;)

linus

(sure this is fake, I guess all of the thousands Linux Con attendees want picture with Linus, so the organizers solved this very elegant – there was photo corner where they take picture of you then mix with Linus on background :) so he even doesn’t know how many people took picture with him – do not tell anyone!)

At the end of the Linux Con there were contest with prizes:

Three A10-OLinuXino-LIME were given away as prizes :)

Active 3D printers made 3D printer with A20-OLinuXino-MICRO and 10″ Touchscreen interface.

All we can say is WOW – nice encolusre!

This is Open Source project and you can download all files on their web.
