The ATtiny Series Is A Great Companion In Isolation

As a consequence of the social distancing and self isolation, many a maker has been searching for ways to cure boredom. So what happens when you put a maker in a closed space with electronics parts. The answer is a bunch of random microcontroller projects that help beat boredom. [Danac1886] posts a video with a bunch of experiments with the ATtiny series of microcontrollers which can be a source of time-killing inspiration for these tough days of solitude.

The video is based upon a variety of controllers ranging from the ATtiny85 to the ATtiny84 and even includes the ATtiny2313. There is also a project with the ATtiny10, an SMD SOT23-6 package that is quite amazing to behold. All the devices can be programmed using the Ardino as an ISP so all you need is another Arduino lying around in case you do not have an AVR ICSP.

As for the projects themselves, there is an assortment of things that start with the basic blinking LED, adding an I2C LCD and then moving on to a 7 segment display counting up with variable speed controlled with a pot. We really loved how much these tiny projects inspire and can help someone get started with basic electronics and programming.

If you are looking to get started, have a look at the Jumbo LED with the Attiny10 and we assure you, it will brighten your day.

Productivity, Unfinished Projects, And Letting Go

Most of us have been there, some projects just don’t get finished. Everyone shelves an in-progress build from time to time, and some hackers drop almost every project for fully finishing it. Why does it happen? What can we do about it? Or does it even matter? My own most memorable one is the wine glass rack I was making for my sister’s birthday, still sitting incomplete on a shelf eleven years later.

The answer may lie in what you consider to be a “done” project. Is it a fully completed build with every possible feature implemented and polished? With that rubric you could be counting all of your completed projects on one hand. What are you really getting out of your personal projects? It’s an interesting topic to consider as pivoting your mindset can end up boosting your productivity. So let’s dig in!

A Homemade Bubble Robot For The Kids

bubbles-machine

Kids generally can be amused pretty easily, but when jangling keys stop holding their interest you might want to take a look at [drenehtsral]’s new project. He’s created an automatic bubble robot (YouTube link) that keeps the kids endlessly entertained!

The project started as an idea at a festival where one of [drenehtsral]’s kids took great interest at a bubble machine. [drenehtsral] had never heard of a bubble machine before, but it turns out that it’s pretty simple in practice. All that’s required is a tank of soapy water, a motor to turn the bubble wands, and a fan to form the bubbles and make them waft gently through the air.

[drenehtsral] also used a 12V battery for power, some other hardware to hold it all together, and a 5V regulator and some other control electronics for the fan and the motor. He notes that he could have bought a bubble machine but in true hacker style found it fun to build himself. The next step in this project could be something to vary the size of the bubbles, or perhaps a set of wheels for the robot so it can entertain the kids on the move!

Portal Gun Hack Approaches 1.5 Million Views. More Fun Hacks To Come!

 

The quick and simple portal gun hack was published a little ver a week ago and has cleared almost 1.5 million views. This is just a taste of things to come as we plunge into creating more fun original content for hackaday. If you haven’t yet, you should go subscribe to our youtube channel.

We have many more exciting projects planned for the near future. Projects involving high voltage, lasers, and thermite! We could always use more ideas though. What projects would you like to see done? Think big, we want to remind people just how awesome hacking can be!

We now have access to some high speed cameras, a wonderful and professional gentleman named [Jay] who is an astounding video editor, and quite possibly the brightest readership in the universe. Let us know your ideas for awesome projects!

Cornell Final Project List

Looking for an interesting project to do using an Atmel Mega644? Students at Cornell University have got you covered. They were required to choose, design, and build a project using the microcontroller; and this year is quite promising with video object tracking, the always popular theremins, helicopters, Potentiostats, even Pavlovian conditioned mosquitoes, and more.

Of course all the previous years are included as well, making over 350 projects total.

Bus Pirate Firmware Update (v.0c), JTAG And More

stat

Download: buspirate.v0c.zip

A few weeks ago we wrote about our Bus Pirate universal serial interface tool. We used the recent holiday to add some new features, like a JTAG programmer, macros, frequency measurement, and more. A major code reorganization makes everything easier to read and update.

Check out the a demonstration of the new features below. We’re compiling a roadmap and wish list, so share your ideas in the comments. You can also see how we used the Bus Pirate to read a smart card and test-drive an I2C crystal oscillator.
