I have a new post on Hackaday: The Spade Hardware Description Language.
First post!
ATtiny85 in HW-260 board
I have my ATtiny85 microcontroller installed in a HW-260 development board (purchased from AliExpress). I program the ATtiny85 with the SparkFun Tiny AVR Programmer, the setup guide is here: Tiny AVR Programmer Hookup Guide.
On the SparkFun programmer the onboard LED is PB0. On the HW-260 the onboard LED is PB1. This is the code I used to flash the HW-260 LED:
#define LED_BUILTIN PB1
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
You can see the programmer settings I used in Arduino IDE in this screenshot:

Tekkikid Components
Today on Hackaday this was mentioned: Repair/Restoration: Matra & Hatchette Alice 32. In the video the presenter said that Tekkikid Components was a good place to buy capacitors (if you’re in the UK I guess…).
Are you the right person to design complex electronic boards?
This evening I watched Are you the right person to design complex electronic boards? which discusses what being a professional electronics designer entails. I particularly liked this slide which compares and contrasts the books a hobbyist might read versus what a professional might read.
The discovery of oxygen
This video about the discovery of oxygen is interesting: This IMPOSSIBLE Theory Led to the Discovery of Oxygen.

Introducing Learning the Art of Electronics | Learning Electronics In The Lab With Jay Jay
This post is part of my video blog and you can find more information about this video over here.
You can support this channel on Patreon: patreon.com/JohnElliotV
This project’s homepage is here: John’s wiki ยง Learning the Art of Electronics.
In this video we introduce a new feature of the show. In these segments we will be working through Learning the Art of Electronics.
We will be doing a total of 27 videos for this feature. 25 labs, this introduction, and a conclusion. Videos will come out on the first Tuesday of every month (hopefully!).
We did a new book teardown for this book last year: New Book Teardown #3: Learning The Art of Electronics: A Hands-On Lab Course (2016) | In The Lab. You can see in the comments a number of people encouraged me to make videos for this book, so that’s what we’re doing now.
Also a shout out to my mate over on Learning as a hobby for encouraging me to undertake this project.
Thanks very much for watching! And please remember to hit like and subscribe! :)
