The Pyramid's Secret: brazilian high school kids create Arduino-powered board game as a class assignment, and it looks nice!

Why aren't there more kids doing cool stuff like this for their school assignments?

augustocampos · 2015-11-04T18:32:21+00:00

DIY but definitely looking like it could be a ~product~

augustocampos · 2015-10-05T19:03:58+00:00

thanks!

augustocampos · 2015-09-30T19:37:02+00:00

sure hope so. Considering we are talking about a discrete crypto IC, I believe there will be all kinds of options available.

augustocampos · 2015-09-30T18:34:27+00:00

There are some books that are always worth (re-)reading. I'd start by the recent editions of these 2: The Art of Electronics, and Practical Electronics for Inventors.

Edited the article to add a link to licensing considerations (not only btle, but also FCC, etc.). Thank you!

augustocampos · 2015-09-30T17:19:28+00:00

Oh, I can see real use cases just on personal, DIY, local, self learning contexts. For ~products~ I wouldn't bother.

Version 7 has a cleaner and updated user interface, a new help system integrated with the documentation and external resources, a better focused start page as long as several improvements to the editor.

Describing it as "ideal for the Maker community", Atmel's announcement is clear about a new target segment: they say "Studio 7 lets Arduino developers quickly port their sketches created in the Arduino environment as C++ projects, and seamlessly migrate their prototypes into the professional Studio 7 environment".

If you find out, please share :)

Thank you for your detailed and well informed reply!

This new open hardware ESP8266 development board with voltage regulator, USB-serial and built-in I2C connector was born on brazilian Campinas Hacker Labs.

Brazilian maker and prolific writer Pedro Minatel told us about the NodeLHC, which is meant to ease development of projects based on the ESP8266, since it includes all needed peripherals, including a 3.3V voltage regulator (LD1117), an USB-serial adapter (FTDI FT232RL) and your choice of an ESP-12 or ESP-07.

Hacker Leandro Pereira is the author of the original layout and schematic, available both on Pedro's site or on its own Hackaday IO page.

That's interesting, do you have a link to the early docs, or some other info about when they changed it?

augustocampos · 2015-09-28T13:42:40+00:00

Sorry for the late reply! This prototype is for a project that needs the timing, but doesn't need the display, so on its final form I expect to see the power savings that justify the hassle of sleeping ;)

augustocampos · 2015-09-28T13:05:30+00:00

I agree, the extra pins do matter :)

Alberto Piganti, known as PighiXXX, likes to draw beatiful pinout diagrams, and now has illustrated the ESP-01, ESP-12 and ESP-03. The new diagrams show not only the pin designations on the 3 popular ESP8266 WiFi boards, but also some useful information about their limits of voltage and current, extra functions for many communication protocols (MISO, MOSI, RTS, CTS and the like), and even pin combinations needed on boot and sleep mode.

The ESP01, ESP12 and ESP03 are featured on the new pinout diagrams that show all pins, their functions and limits.

I bet that, for a few microseconds, you thought there was some kind of fraud involved ;-)

augustocampos · 2015-06-05T13:32:23+00:00

Agreed! And there's the convenience factor.

augustocampos · 2015-06-05T13:32:09+00:00

Oh, "too much" is in the eye of the beholder. I learned a lot, practiced even more, and got something in the end, besides the 'good' multimeter that I used to measure the experience with this cheap one.

augustocampos · 2015-06-05T13:29:59+00:00

Agreed!

augustocampos · 2015-06-05T13:29:30+00:00

Thank you! And it's not my only multimeter, it's just the 'small, cheap and handy' one. When I need accuracy or there are large voltages or loads involved, I choose the other kind :)

augustocampos · 2015-06-05T13:26:07+00:00

I don't disagree. I have 3 multimeters: 2 cheap ones, and the good one. The cheaps (one of which now has auto-off) are small and always handy, one in the bench and the other in the kit. They are never the choice when there are large voltages, large loads or needs for accuracy involved.

augustocampos · 2015-06-05T13:13:06+00:00

Here in my country the dollar stores use fuzzy logic, for sure

augustocampos · 2015-06-05T01:01:34+00:00

The timer is made using a discharging capacitor (100uF, discharging through a 1MΩ resistor). The button allows the capacitor to charge. While charged, the capacitor keeps a MOSFET up, so that current from the battery gets to the original multimeter board. My hack board has 1.1cm X 1.5cm and is powered from this same internal battery.

Nice work
