TSYS01 Temperature sensor board available

ELL-i is happy to announce another product to be sold through Elecrow’s webshop: TSYS01 temperature sensor board. The sensor itself is one of the most accurate temperature sensors we know of, it can reach absolute accuracy of 0.1 C in range of -5 … 50 C and it has resolution of 0.01C. 14587888880

The full operating range of sensor is -40 … 125 C. The pins are brought out in breadboard compatible manner, and both I2C and SPI communication are supported.

More detailed description, schematic and Arduino code  can be found at our github repository.

RasPoE boards available from Elecrow’s webshop

After long wait, the first production batch of RasPoE boards is now available. Elecrow has a long expertise in bringing ideas to market, and they will produce the boards as well as arrange the shipping worldwide. For those of you who need to hear no more, Here is the link. There is a a limited number of boards available, enough to fulfill the orders in our kickstarter campaign as well as some extras. Get yours today!

You can find out more about RasPoE in our Product page. RasPoE is open source, if you’re interested in design files you can check them out (no pun intended) at out github repository.

We are happy to announce our co-operation with Elecrow. For a long time, they have provided us with prototype PCBs and various bits and parts for many projects. Now our customers can benefit from their large inventory of parts and experience in worldwide logistics.

ELL-i DailyGreens at Google Launchpad in EIT Digital

Huh, last week was intense. I was at EIT Digital in Otaniemi taking part in a week long workshop training mentoring session developing our DailyGreens product. We learned a huge amount on things like product development, user surveys, user experience analysis, technologies, marketing and pitching.

I’m sure this made me a better person in many ways but also taught me a lot. Thanks, all.

Social distributed groupwork workshop at Helsinki Hacklab

I’ve started to have weekly sessions at Helsinki Hacklab on mondays after normal office hours on subjects related to working effectively via Github or some similar version control system.

I have a vision of cultivating ourselves to become better programmers and better makers together, teaching ourselves and each other the kinds of skills necessary that we can succesfully act as independent agents in our and other open source joint efforts.

This not only means being sufficiently apt at using Git and Github, but being reasonably learned about the larger picture; software architecture, network architecture, system architecture, electronics, and the tools and thinking paradigms prevalent at each abstraction.

My vision is actually deeper and goes well beyond what I can even describe in here, but we have already begun to walk the journey. Join us at:

Hackerspace Summit Finland 15 ½ aftermath

There was an event known as Hackerspace Summit Finland hosted at Helsinki Hacklab last weekend. Makers and hackers from all over Finland came to see how Helsinki is doing and exchanged some ideas. There was a friendly robot race, sauna, short presentations about various subjects and so on.

ELL-i presented briefly the RasPoE, Power over Ethernet board for Raspberry Pi. Our campaign is still running, and we were happy to fuel the imagination of people attending. We also received a lot of nice ideas for products which we might design after our current campaign is finished. ELL-i was also happy to provide some food for the attendees, as one person put it: whenever there is an event with Eero cooking, you should attend it.

Raspberry Pi PoE shield now in IndieGoGo!

We have launched our RasPoE, the Power over Ethernet addon board for Raspberry Pi.
For those of you who need to hear no more, here is the link:

https://www.indiegogo.com/projects/raspoe-raspberry-pi-poe-shield

Please spread the word!

There are a few boards like ours on the market, but we are the first GPL3 licensed
one as far as we know. The current design is available at

https://github.com/ojousima/RaspberryPi-PoE

The design is done in KiCAD, which is Open Source electronics design program. We’ll
clear up the schematics and publish full parts list with distributors so you can
even assemble your own boards if you want to! All this is still quite a lot of work,
so please give us a few weeks to polish the design as we publish it.

We’ll work to merge the PCB footprints created for the board back to KiCAD upstream
during the campaign, your backing allows us to expand the common Open framework for
electronics design.

We would like to thank the community and awesome support we have had ever since the
beginning. Especially Vaasa’s Hackerspace’s contribution to us was extremely
important, as they found out about the transient vulnerability in Ethernet PHY of
Raspberry Pi. Open developing of the boards with the community let us find a
critical design flaw, which is now fixed before our release. Even if our campaign is
not successful, the knowledge we gained during this spring is now out in the open
where everyone can benefit from it.

There has been a lot of interest in building derivative works based on our board. As
we’re committed to values of Open Source, we’re always happy to see our designs grow
into something else. Please contact us with your ideas and suggestions, even if it’s
just to let us know that you’re making something cool. This way we can focus at
something else at ELL-i and avoid duplicating work.

And since it was such a long wall of a text, here’s the link again!

Let’s make the first Open Source Raspberry Pi PoE Board a product!

Hackathon aftermath

We setup the Helsinki Hacklab for our hackathon. It was a quick matter of connecting our PoE switch to rack and presenting the Raspberrys and PoE shields, PoELL-i Nucleos and various electronics modules, parts and shields. Soon we were having music over Ethernet.

We assembled a few of the new PoE-shields,

It was very interesting to see what happens when the area has a lot of creative people, and facilities to support them around. Helsinki Hacklab had Ethernet sockets already available all over the place, and with our PoE switch we could enable PoE in any socket in less than a minute.

Whenever there was a convenient spot for building a project, things happened at amazing pace. Want to try if that stepper motor driver can drive the curtains, but don’t want to risk your laptop to higher-than-USB-voltages? Plug in a Raspberry with PoE, power Arduino through Raspberry Pi’s USB and you’re ready to go!

There was something amazing created in our hackathon, and we feel it deserves it’s own in-depth writeup. Stay tuned to find out what it was! In meanwhile, join in our mailing list here and we’ll email you before our campaign starts so you can snatch those Early Bird rewards!
