Hacking Hackaday.io from CircuitPython

Hack a Day - 5 hours 43 min ago

If you’ve ever engaged in social media, you’re familiar with the little thrill you receive when your post, tweet, or project gets a like. But, if logging in feels like too much overhead to obtain your dopamine reward, [pt’s] CircuitPython Hackaday portal may be just what you’re looking for. This project creates a stand-alone counter to display the number of “skulls” (aka likes) received by a project on hackaday.io, and of course, it’s currently counting its own.

The code is running on a SAMD51 (Cortex M4) microcontroller and serving up the skulls on 240×320 TFT display. For WiFi connectivity, the project uses an ESP-32 controlled through the usual AT command set. All the gory details of this interaction are abstracted away by a CircuitPython library, which is great because that code really isn’t something you want to write for every project. The program accesses the hackaday.io API to retrieve the number of skulls for the project, but could be easily modified to interface with any service that returned a JSON result.

We’ve been seeing a lot of CircuitPython code lately. Just in case you’re not familiar with it, CircuitPython is Adafruit’s version of Micropython, a python language targeted at embedded processors. While it sounds like something concocted purely to make old-school embedded-C programmers grumble, it’s actually powerful and convenient for embedded prototyping and development. Fueled by the speed of the latest inexpensive microcontrollers and a rapidly growing set of libraries that take the sting out of using integrated peripherals and common hacker-friendly parts, it offers a solid alternative to older embedded frameworks. There are lots of examples around if you want to get started, and we’re maintaining our own list of CircuitPython projects over on hackaday.io that you can check out.

You can see a video of the display after the break. It’s not a live stream, so you won’t see your like appear on the display, but rest assured, [pt] will!

We’ve seen [pt]’s work before. Including – you know – writing our first post ever.

Watch an AI robot program itself to, er, pick things up and push them around

Why can't robots just learn to do things without being told?

Vid Robots normally need to be programmed in order to get them to perform a particular task, but they can be coaxed into writing the instructions themselves with the help of machine learning, according to research published in Science.…

Looking to run tasks like a subscription

Is it at all possible for Tasker to receive have actions running in parallel?

I'd like to have different people text me and then receive a motivational text every day for a week. The idea is that each week long "subscription" would be handled by Tasker alternating the WAIT action (which I believe is handled by an alarm being set for Tasker to do an action, rather than an actual countdown) with a SEND SMS action.

It seems like the current set up works OK if only one person texts in, but a 2nd "subscriber" picks up the text stream at that point and the texts to the original "subscriber" stop.

I have set the collision handling to run both tasks at the same time.

It seems it is theoretically doable for Tasker to do this, but any help would be appreciated!

Destroy scene not working.

I have a scene with a number picker and a button. The button runs a different task and is supposed to destroy the scene after it is pressed and run the task but the screen just stays up. I have tried changing the "display as" settings but that doesn't seem to help.

Tasker standalone app runs task immediately instead of waiting for profile to trigger

I'm making a standalone app for my friend to help him download youtube videos.

I have a Profile with "Application > Youtube" and "Variable Set > %CLIP" as triggers which detects when you copy a link to clipboard while in the youtube app. When this happens it runs a task which brings up a menu asking if you want to proceed.

This works fine when the profile is running from Tasker but when I export a standalone app from the project and run the app, it just comes up with the menu straight away. I want it to run in the background and wait for the conditions to be met before bringing up the menu.

Can anyone help me?

Mining malware evades agent-based cloud security solutions

Cloud infrastructures are a growing target for threat actors looking to mine cryptocurrency, as their vast computational power allows them to multiply the mining malware’s effect. Keeping its presence from being noticed as long as possible is, naturally, a goal worth striving for and criminals are coming up with new ways to achieve it. One of the approaches, employed by a threat group dubbed Rocke, is to uninstall agent-based cloud security products before downloading the … More →
