ACK1 Makes Getting to Know the ATtiny1616 Easy

-

Many readers will be familiar with Microchip’s ATtiny85, which has been a popular choice for DIY projects in the past for its low price and (for the time) small size. But those looking for a more modern and capable 8-bit chip may find the ATtiny1616-MNR of interest. It offers expanded flash storage, more GPIO, and ditches SPI programming in favor of UPDI — a protocol that can be done using nothing more than an USB-UART converter and a resistor.

What’s in the kit if you buy it.

But here’s the catch: the new chip is only available in SMD and there are far fewer tutorials for it! That’s why [Bradán Lane] has created ACK1, a cute little AVR Coding Kit for those of us who want to play with the ATtiny1616 and a companion for his free and open-source course.

The board contains an array of 6 by 7 LEDs in a charlieplexed configuration, a large piezo buzzer, two push buttons, an on/off switch, and a CR2032 battery holder to keep it on without the need for a cable. The kit looks gorgeous in its white-on-black theme with gold plated contacts and can be had for $20 on Tindie at the time of writing.

The ATtiny1616 itself runs at up to 20 MHz and has 17 GPIO pins, 16 KiB of flash storage, 2 KiB of RAM, and 256 bytes of EEPROM for configuration — making it roughly on par with the original Arduino Uno.

The course that goes hand-in-hand with the ACK1 is all about the features of the ATtiny1616, from the basics of using the programmer to reading the buttons, using timers, driving the charlieplexed LEDs, storing data in the EEPROM and much more. Though it does not cover the basics of C, the course is free, and even lisenced MIT, so that anyone can share it and improve upon it.

If you enjoy seeing beautiful microcontrollers, you’ll definitely want to see the stylish Uno Plus+.

Modern Radio Receiver Architecture: From Regenerative to Direct Conversion

-

Modern radio receivers have a distinct advantage over the common early designs which I covered in my previous article . Most of the receivers you will have worked with over the past couple decades are designs by Edwin Armstrong ; regenerative, superregenerative, or most commonly superheterodyne. These are distinguished by a few fascinating key traits that bring both benefits and drawbacks. Today let’s dive into Mr. Armstrong’s receivers. I’ll also talk about DC receivers which, despite the name, are not made to listen to batteries. These are receivers you are much more likely to encounter in modern equipment. Regenerative and Superregenerative The regenerative receiver is all about doing more with less. You still see some of these in simple applications like RF remote controls. The idea derives from how an oscillator works. In a simple way of thinking, an oscillator is an amplifier with enough positive feedback that any tiny signal at the right frequency will amplify and then, throu...

Hackaday Links: May 31, 2020

We begin with sad news indeed as we mark the passing of Marcel van Kervinck on Monday. The name might not ring a bell, but his project, the Gigatron TTL computer , certainly will. We did a deep dive on the microprocessor-less computer a while back, and Marcel was a regular at conferences and on the Gigatron forums, supporting users and extending what the computer can do. He was pretty candid about his health issues, and I’ll add that when I approached him a few weeks ago out of the blue about perhaps doing a Hack Chat about Gigatron, he was brutally honest about how little time he had left and that he wouldn’t make it that long. I was blown away by the grace and courage he displayed. His co-conspirator Walter Belger will carry on the Gigatron mission, including joining us for a Hack Chat on June 24. In the meantime, this might be a great time to pick up a Gigatron kit before they’re all sold out and get busy soldering all those delicious through-hole TTL chips. May of 2020 is the mo...

Homebrew 68K Micro-ATX Computer Runs Its Own OS

-

We’re no stranger to home built Motorola 68000 computers here at Hackaday, but more often than not, they tend to be an experiment in retro minimalism. The venerable processor is usually joined by only a handful of components, and there’s an excellent chance they’ll have taken up residence on a piece of perfboard. Then [NotArtyom] sent in his Blitz , and launched the bar into the stratosphere. Make no mistake, the Blitz isn’t just some simple demo of classic chips. The open hardware motherboard has onboard floppy, IDE, and PS/2 interfaces, with a trio of 8-bit ISA expansion slots for good measure. The  Motorola 68030 CPU is humming along at 50 MHz, with 4 MB of RAM and 512 KB of ROM along for the ride. Designed to fit the Micro-ATX motherboard standard, you can even mount the Blitz in a contemporary PC case and run it on a standard ATX power supply. An earlier prototype of the Blitz motherboard. As if the hardware wasn’t impressive enough, [NotArtyom] went ahead and created hi...
