We’re Making it Rain Achievements This Year

We just dished out the first round of achievements to a bunch of hardware projects and there’s a lot more to come.

You may have missed it in all the fanfare last week, so today we take a closer look. Achievements are the newest edition to the Hackaday Prize and we’re really excited about them! With so much creativity in the projects we see entered, these achievements recognize a range of different aspects from serious to lighthearted, and even the downright absurd. There can be only 20 finalists in each challenge of the Prize, but there can be dozens of projects that unlock each achievement.

Today we’re taking a look at three of the achievements: Voltron, Pickle Rick, and the League of Extraordinary Cyborgs. You can also pursue the current list of achievements for an idea of what they’re all about.

Voltron Achievement

The five projects that have unlocked the Voltron Achievement aren’t about defending the universe (but if that’s what you’re doing, cool!). What we’re looking for is many things coming together to be greater than the whole. Two great examples are the Hexabitz project which is an edge-soldered modular PCB system, and a project that envisions swarm robotics for construction, inspection, and maintenance.

Pickle Rick Achievement

Does this need explaining? If your brain skips a cycle and your lips utter a halting “What?!” then you’ve unlocked the Pickle Rick Achievement. These are the out-of-the-ordinary hacks borne of the because-I-can mentality and we love them. The first two projects in this group are a neon 7-segment display (complete with bulky toggle switches and mechanical relays) and a robot snake that transforms into a robot car. What?!

League of Extraordinary Cyborgs Achievement

It’s dangerous to go alone. OK, maybe it’s not, but you can get a lot more done as a close-knit team! We’re looking for team entries, which is how you unlock the League of Extraordinary Cyborgs Achievement.

Unlocks and the Achievements We Forgot

These achievements are easy to unlock. Your project needs to be a Hackaday Prize entry, and meet the achievement criteria. They don’t come with a cash prize (and don’t affect your chances of winning one). Achievements are a tip of the hat to the hackers who are passionate about the hardware they’re building.

We’ll be digging through entries, awarding these as we go, but of course we would love your help. When you see projects perfect for an achievement, leave a comment on that page with your support. You can also send a Hackaday.io message to Stephen Tranovich, Technical Community Leader at Hackaday.io and the person most on the lookout for awarding achievements, requesting an achievement unlock.

The currently displayed list doesn’t include all of the achievements. Some of them are secret (we’ll tell you when we start awarding those). We will be adding more along the way. If an idea for an interesting achievement pops into your mind, let us know in the comments below and we might add it!

Water Level Sensors, Alexa in a Fish, and Modular Synths During World Create Day

On Saturday we saw a flood of interesting hacks come to life as more than 100 community organized meetups were held for World Create Day. Thank you to all of the organizers who made these events possible, and for everyone who decided to get together and hack.

Students Learning Hardware Design in Islamabad, Pakistan

The students at LearnOBots took on a slew of great projects during World Create Day like a smart medicine dispenser, electronics that control mains appliances, parking sensors, and a waste bin that encourages you to feed it. The group did a wonderful job of showing off their event by publishing several updates with pictures, stories, and video presentations from all the students. Nice work!

Non-standard Circuits: Jazz For Electrons

How creative are you when you make your circuit boards? Do you hunt around for different materials to use for the board? As long as it’s an insulator and can handle the heat of a soldering iron, then anything’s fair game. Or do you use a board at all? Let’s explore some options, both old favorites and some you may not have seen before, and see if we can get our creative juices flowing.

Transparent Circuit Boards

Let’s start with the desire to show more circuit and less board. For that we can start with [CNLohr]’s circuits on glass, usually microscope slides. What’s especially nice about his is that he provides detailed videos of the whole process, including all the failed things he tried along the way. Since he didn’t start with copper clad board, he instead glued his copper sheet to the glass using Loctite 3301. That was followed by the usual etching process, though with plenty of gotchas along the way.

In the end, he made a number of circuits, including an LED clock with the LEDs on the glass itself, and even attempted leading the community in making a glass keytar. The latter didn’t work out, but the resulting glass circuits are a work of art anyway.

What about making a transparent circuit board out of acrylic? [Frank Zhao] attempted just that by laser cutting troughs into the acrylic for the traces, and then drawing in nickel ink. But something in the ink ate into the acrylic, and as if that wasn’t bad enough, the voltage drop across the nickel was too high for his circuit. Suggestions were made in the comments for how to solve these problems, but unless we missed it, we haven’t seen another attempt yet.

But we’ve only just begun. What if you wanted even more transparency?

The Best Of VCF East

Last weekend was the Vintage Computer Festival East in Wall, New Jersey. While this yearly gathering of nerds nerding out on old computers might be a bit too obscure for some, there are always amazing exhibits of actual historical importance. A few Enigma machines showed up, and the rarest Commodore goodies made an appearance. We saw the pre-history of Hackaday and ‘maker’ culture with Southwest Technical Products Corporation, and found out it was probably, possible to build a RepRap in the 80s. You can’t know where you’re going unless you know where you came from, and even though the old timers were a bit more grizzled than us the Vintage Computer Festival shows how little things have actually changed.

What was the coolest and weirdest stuff at VCF? What does the Silverball pinball museum look like? Check that out below.

Fail of the Week: NASA Edition

There’s a reason we often use the phrase “It ain’t Rocket Science”. Because real rocket science IS difficult. It is dangerous and complicated, and a lot of things can and do go wrong, often with disastrous consequences. It is imperative that the lessons learned from past failures must be documented and disseminated to prevent future mishaps. This is much easier said than done. There’s a large number of agencies and laboratories working on multiple projects over long periods of time. Which is why NASA has set up NASA Lessons Learned — a central, online database of issues documented by contributors from within NASA as well as other organizations.

The system is managed by a steering committee consisting of members from all NASA centers. Public access is limited to a summary of the original driving event, lessons learned and recommendations. But even this information can be quite useful for common folks. For example, this lesson on Guidance for NASA Selection & Application of DC-DC Converters contains several bits of useful wisdom. Or this one about IC’s being damaged due to capacitor residual discharge during assembly. If you ever need to add a conformal coating to your hardware, check how Glass Cased Components Fractured as a Result of Shrinkage in Coating/Bonding Materials Applied in Excessive Amounts. Finally, something we have all experienced when working with polarized components — Reverse Polarity Concerns With Tantalum Capacitors. Here is a more specific Technical Note on polarized capacitors (pdf): Preventing Incorrect Installation of Polarized Capacitors.

Unfortunately, all of this body of past knowledge is sometimes still not enough to prevent problems. Case in point is a recently discovered issue on the ISS — a completely avoidable power supply mistake. Science payloads attach to the ISS via holders called the ExPRESS logistics carriers. These provide mechanical anchoring, electrical power and data links. Inside the carriers, the power supply meant to supply 28V to the payloads was found to have a few capacitors mounted the other way around. This has forced the payloads to use the 120V supply instead, requiring them to have an additional 120V to 28V converter retrofit. This means modifying the existing hardware and factoring in additional weight, volume, heat, cost and other issues when adding the extra converter. If you’d like to dig into the details, check out this article about NASA’s power supply fail.

Thanks to [Jarek] for tipping us about this.

Three of our Favorite Hackers

It’s one thing to pull off a hack, it’s another entirely to explain it so that everyone can understand. [Micah Elizabeth Scott] took a really complicated concept (power glitching attacks) and boiled a successful reverse engineering process into one incredible video. scanlime-power-smoothing-alterationsWe know, watching 30 minutes of video these days is a huge ask, just watch it and thank us later.

She explains the process of dumping firmware from a Wacom tablet by hacking what the USB descriptors share. This involves altering the power rail smoothing circuit, building her own clock control board to work with the target hardware and a ChipWhisperer, then iterating the glitch until she hones in on the perfect attack.

This, of course isn’t her first rodeo. Also known as [scanlime], she’s been on the scene in a big way for a while now. Check out more of her work, and perhaps congratulate her on recently being scooped up for a Principal Researcher role that we’d like to attribute in part to the hacks she’s been demoing online. You should also thank her for being a Hackaday Prize Judge in 2015 and 2016.

led-handbag-debra-ansel-geekmomprojects-closeupThis year we spotted [Debra Ansell] at Maker Faire, not as an exhibitor but an attendee taking her newest creation out in the wild. [Debra’s] LED matrix handbag is a marvel of fabrication — both design and execution are so great it is hard to believe this is not a commercially available product. But no, the one-of-a-kind bag uses woven leather strips spaced perfectly to leave room for WS2812 RGB LED modules to nestle perfectly. Look slike she even posted a tutorial since we last checked! If you don’t recognize her name, you might recognize her company: GeekMomProjects. She’s the person behind EtchABot, a robotic addendum to the diminutive pocket Etch a Sketch which [Debra] sells on Tindie.

The custom PCBs of Veronica (in troubleshoot mode)

Our fascination with [Quinn Dunki]’s work goes way way back. She has a software background but her hardware chops are to be admired. Recently we’ve delighted in her efforts to beef up the fabrication abilities of her shop. Want to know how to vet your new drill press — [Quinn] has you covered. We also enjoyed seeing her bring an inexpensive bandsaw up to snuff. There are too many other great hacks from [Quinn Dunki] to start naming them all. We’ll leave you with her amazing work on Veronica, the scratch-built 6502 computer that she brought with her for her Hackaday 10th Anniversary talk. Her avatar at the top is from one of her PCB etching tutorials.

Celebrating Ada Lovelace Day

Today is the second Tuesday in October — it’s Ada Lovelace day, a worldwide celebration of women in science and technology. The hackers above are some of our all-around favorites and we have featured all of their work frequently. Their impact on technology is undeniable, we give them much respect for their skills and accomplishments. We’d love to hear your own favorite examples of women who have incredible game when it comes to hardware hacking. Please let us know in the comments below.

Four Of Our Favorite Hardware Talks

The Hackaday SuperConference is the greatest gathering of hardware hackers on the planet. Last year at the SuperCon, we saw talks on building systems from scratch, creating new and interesting uses for technology, and bringing those electronic bits to market. What are we talking about? Here are four of the best talks from last year’s Hackaday SuperConference:
