A Beautifully Illustrated Guide To Making

November 10, 2024 by Navarre Bartz 13 Comments

If you’ve ever been wondering what you should make next, it can be a daunting task to decide with the firehose of inspiration coming straight from the series of tubes that makeup the World Wide Web. Perhaps a more curated digital catalog of projects would help?

Featuring “1000 Useful Things to Make,” [NODE]’s Make it Yourself is a beautifully-illustrated catalog of open source and DIY projects spanning a number of domains including camping gear, furniture, music, and maker tools. Each image is a link to the original project and there’s a handy icon by each denoting what skills are needed, such as sewing or 3D printing.

If you haven’t seen [NODE]’s work before, he uses line art to illustrate his projects and has given all of these projects the same treatment on the (virtual) page with credits to the original creators in the footnotes. We hope a future edition will include tractors and houses to truly rival the Sears catalog of yore, but it’s hard to complain when we already have so many projects we could choose to build.

Many of the projects may seem familiar, if slightly fancier when illustrated in line art, like the Ploopy headphones, this retro audio player, or the Keybon adaptive macro pad.

Sometimes It’s Not The Solution

June 1, 2024 by Elliot Williams 54 Comments

Watching a video about a scratch-built ultra-precise switch for metrology last week reminded me that it’s not always the projects that are the most elegant solutions that I enjoy reading about the most. Sometimes I like reading about hackers’ projects more for the description of the problem they’re facing.

A good problem invites you to brainstorm along. In the case of [Marco Reps]’s switches, for instance, they need to be extraordinarily temperature stable, which means being made out of a single type of metal to avoid unintentional thermocouple joints. And ideally, they should be as cheap as possible. Once you see one good solution, you can’t help but think of others – just reading the comments on that article shows you how inspiring a good problem can be. I’m not worried about these issues in any of my work, but it would be cool to have to.

Similarly, this week, I really liked [Michael Prasthofer]’s deep dive into converting a normal camera into a spectrometer. His solutions were all very elegant, but what was most interesting were the various problems he faced along the way. Things that you just wouldn’t expect end up mattering, like diffraction gratings being differently sensitive across the spectrum when light comes in from different angles. You can learn a lot from other people’s problems.

So, hackers everywhere, please share your problems with us! You think that your application is “too niche” to be of general interest? Maybe it’s another example of a problem that’s unique enough to be interesting just on its own. Let’s see what your up against. A cool problem is at least as interesting as a clever solution.

Goals And Goalposts

August 14, 2021 by Elliot Williams 14 Comments

In the winter, I hatched a vague plan to learn some of the modern unmanned aerial vehicle tech. Everybody needs an autonomous vehicle, and we’ve got some good flying fields within walking distance, so it seemed like it could work. Being me, that meant buying the cheapest gear that could possibly work, building up the plane by myself, and generally figuring out as much as possible along the way. I learn more by making my own mistakes anyway. Sounds like a good summer project.

Fast-forward to August, and the plane is built, controller installed, and I’ve spent most of the last month trying to make them work well together. (The firmware expects a plane with ailerons, and mine doesn’t have them, but apparently I’d rather tweak PID values than simply add a couple wing servos.) But it’s working well enough that it’s launching, flying autonomous waypoint missions, and coming home without any intervention. So, mission accomplished, right?

Nope. When I’m enjoying a project, I have a way of moving the goalposts on myself. I mean, I don’t really want to be done anyway. When a friend asked me a couple weeks ago what I was planning to do with the plane, I said “take nice aerial videos of that farm over there.” Now I see flight opportunities everywhere, and need to work on my skills. The plane needed an OLED display. It probably still needs Bluetooth for local configuration as well. Maybe a better long-range data link…

This is creeping featurism and moving-the-goalposts in the best of ways. And if this were a project with a deadline, or one that I weren’t simply enjoying, it would be a problem. Instead, having relatively low-key goals, meeting them, and letting them inspire me to set the next ones has been a blast. It makes me think of Donald Papp’s great article on creating hacking “win” projects. There he suggests creating simple goals to keep yourself inspired. I don’t think I could have planned out an “optimal” set of goals to begin with — I’ve learned too much along the way that the next goal isn’t obvious until I know what new capabilities I have. Creeping is the only way.

What about you? Do you plan your hobby projects completely in advance? Not at all? Or do you have some kind of hybrid, moving-the-goalposts sort of strategy?

The ATtiny Series Is A Great Companion In Isolation

April 2, 2020 by Inderpreet Singh 11 Comments

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

September 25, 2018 by Steven Dufresne 64 Comments

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

August 13, 2014 by Bryan Cockfield 10 Comments

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!
