Indiegogo – Tinusaur/ATtiny85 Quick Start Boards

Indiegogo Tinusaur ATtiny85 Quick Start Boards

Yes, you read it correct.

We’re planning an Indiegogo crowdfunding campaign for the end of this week.

Why?

We need some help to produce few hundred or more Tinusaur Boards and Tinusaur Bundles that we will keep in stock at our online store.

When?

It is planned for this Friday, February 26th, 2016.

Like the idea?

Support us this Friday!

Stay tuned.

Website design upgrade

under constructionOver the next few days we will be updating the design of our website. That will be primarily the theme but also few other things.

We couldn’t find a way to put the website in “maintenance mode” so some weird things may be visible from time to time until we finish the update.

Wish us luck! ūüėČ

It’s official: the Tinusaur will be presented at Maker Faire in New York

Maker Faire New York - The Greatest Show and Tell on EarthIt’s official: The Tinusaur Project will be presented at the Maker Faire that is taking place in New York this month – on Sunday, September 21st at¬†3:15pm on¬†the “Make: Electronics Stage”

 

Come see us there!

Tinusaur Starter and Tinusaur Board are Available for Preorder

As you already know we ran out of all the kits at our online store and because¬†we also received a lot of questions when the Tinusaur Starter and Tinusaur¬†Board will be¬†available we decided to allow you to preorder¬†them. This way we’ll know how many of you are actually interested in buying so we’ll order the necessary quantities from our suppliers.

If you decided to preorder please should allow us between 2 and 3 weeks to get all the parts from our suppliers.

If you find The Tinusaur Project useful we would really appreciate you considering a small donation. Please look at the right side bar for more information.

Thank again for you interest and support.

 

Out-of-Stock Items at Our Online Store

Dear friends, due to increased popularity of our Tinusaur Project in the last couple of days and unexpected high demand for the kits in our online store . . . we just ran out of almost all of them.

We contacted our suppliers and ordered more parts but it could take up to 3 weeks until they arrive so please be patient.

If you need just the PCB you can order it directly from OSH Park at this address: https://oshpark.com/shared_projects/9IZsFiXL.

Please follow us on Twitter at @tinusaur where we post more updates.

 

 

The Tinusaur Online Store Opens

Tinusaur Starter

Finally, our online store is up and running.

We received some emails asking if we could offer the boards and the parts for purchasing … so we did it. We have to admit that it took us some time to arrange everything but some of the circumstances were beyond our control.

At the moment we have only one product listed – that’s the Tinusaur Starter.

Go to this tinusaur.storenvy.com/products/6076006-tinusaur-starter¬†link if you’d like to buy it.

Tinusaur Starter Buy at Storenvy

We have put up for sale very small batch of those starter kits as we don’t know what the interest will be. Please note that at the moment we don’t do this as a business and we do not make any profit – the sale only covers our expenses.

More information about the Tinusaur Starter kit is available at the Tinusaur Starter page.

IMPORTANT: This is offered as a kit which means that you have to assemble it yourself.

We chose¬†Storenvy¬†for our shopping site and we think that it was a good choice – it’s easy to setup and use but also provides all the functionality that we need at this stage. You can pay for your orders with PayPal.

 

February: Quick update

Tinusaur Project Milestones

This is quick update for what is happening in the lab.

Tinusaur Proto

And by the way, our project was featured on OSHPark Blog, here’s the link …¬†http://blog.oshpark.com/2014/02/staff-picks-for-the-week-of-2-february-2014/. Very glad to see that people are interested in this project.

As follow up to our first Tutorial 001¬†we are planing to put another one –¬†Tutorial 002,¬†probably about how to connect a push-button to the board and receive input from it.

Tinusaur Starter: We are making a beginners kit

Tinusaur Starter Kit

To start making things with the Tinusaur you need the board, the parts, a programmer with a cable and couple of LEDs to make your first blinking lights program for ATtiny85 microcontroller.

Tinusaur Starter Kit for Beginners PartsWe’re ordering the PCBs and the parts from the manufacturers and it seems that the total cost for the full package will be 8 to 9 USD.¬†Once we have everything here we’ll run a small test sale to see what’s the interest in the kit. The estimated cost for delivery of the kit to any country in the world is about 2 USD. So the total cost to get it would be 10 to 11 USD – very affordable for everyone.

Here is a list of everything that will be included in the Tinusaur Starter:

The Tinusaur Board Designing Principals

In this post are discussed some of principals used while designing this board.

Size and form factor

The goal of making this board is not to have a smaller or the smallest PCB that runs on ATtiny. The goal is to have a board that could be used for prototyping simple projects as well as fitting reasonable small (or large, depending on the view) circuits on an additional shield board.

Headers

There are 2 header – one 2×4 – H1 and another one 2×5 – H2.

The idea is that all the outer pins are GND while all the inner pins are connected directly to the MCU. The longer header H2 has its top-left pin connected to the Vcc like the 2nd-row one on the left. That gives us one more power source wire.

MCU

This board could work with the smaller Atmel AVR ATtiny controllers such as ATtiny 25/45/85, ATtiny13 as well as most of their variations – as long as they are in DIP-8 case.

Programming

The programming is done through the standard 10-pin ISP connector using any compatible AVR ISP programmer. On the diagram below it is marked as PC.

The connector is placed on the board in such a way so it could be chopped off if not needed and make the board little smaller. The programming probe, marked as PP on the diagram below, has holes that could help in the cutting.¬†In case you need to connect the board to a programmer again at later time you can solder some wires to what’s left of the probe.

Board

Technical parameters:¬†2 layer board of 0.90×1.40 inches (22.96×35.66 mm).

There are 4 mounting holes marked as MH on the diagram below.

Power

During the development the board could be powered through the ISP programmer.

External power source could be connected to the board through a jumper marked as PS on the diagram below.

There is an optional button-cell battery mount on the back of the board, marked as BM on the diagram below. The battery could be switched on and off using the jumper that is marked as BS on the diagram.

Areas

There are 4 areas that a Tinusaur board could be divided to: A1, A2, A3, A4. That is applicable for the actual Tinusaur main board as well as any shield boards one could produce.

A1, the bottom part of the board:

  • this is the area where the RESET button is placed on the main board.
  • for a shield board that area could be used to put some components and produce a simple circuit.

A2, the mid of the board – heads:

  • there are 2 header – one 2×4 and another one 2×5, they are different for a reason.
  • on the main board, between the headers, is placed the MCU.
  • on a shield board, between the headers, could placed a 8-pin chip or other components.

A3, the top part of the board:

  • there are the minimum required components for the MSU to work – 2 capacitors for the power source and one pull-up resistor for the RESET.
  • jumper for external power.
  • jumper to switch on/off battery.

A4, tip of the board:

  • standard ISP programming connector.

Additionally …

A5, the other side of the board:

  • there is optional cell-button battery mount.
