Mike Harrison’s Reverse Engineering Workshop

Hardware teardowns are awesome when guided by experts. One of our favorites over the years has been [Mike Harrison], who has conquered teardowns of some incredibly rare and exquisitely engineered gear, sharing the adventure on his YouTube channel: mikeselectricstuff. Now he’s putting on a workshop to walk through some of the techniques he uses when looking at equipment for the first time.

[Mike] will be in Pasadena a few days early for the Hackaday Superconference and floated the idea of hosting a workshop. We ordered up some interesting gear which he hasn’t had a chance to look at yet. A dozen lucky workshop attendees will walk through the process [Mike] uses to explore the manufacturing and design choices — skills that will translate to examining any piece of unknown gear. He may even delve into the functionality of the equipment if time allows. Get your ticket right now!

To keep things interesting we’re not going to reveal the equipment until after the fact. But follow the event page where we’ll publish the details of his reverse engineering work after the workshop.

[Mike] is the badge designer for this year’s Hackaday Superconference badge. Unfortunately Supercon is completely sold out (we tried to warn you) but you can check out the badge details he already published. And we will be live streaming the Supercon this year — more details on that next week!

Catching 30 kilowatts with Thor’s Hammer

Can you really catch lightning with Mjolnir, the mythical hammer of Thor? If you’re [James Hobson] you can get pretty darn close. He’s a long time writer at Hackaday who’s been building an epic following on his YouTube channel by making the digital effects of blockbuster movies into practical effects. Today he released a video showing how he channeled a jolt of lightning with hammer held high.

The lightning source for this hack is a huge Tesla coil held overhead by a telescoping lift. Humans and high voltage mix poorly, which is why you can’t actually tell this is [James]. He’s wearing a full body suit of grounded chainmail which serves as a Faraday cage, safely directing the current around him to avoid a literally heart-stopping moment. Check out the antics in the video after the break.

Longtime readers will remember [Caleb Kraft’s] take on Mjolnir, a build that placed the Tesla coil in the hammer itself. [James]’ version is undeniably more impressive, with the tradeoff that it’s wholly unportable. While we’re on the topic of mythical hammers, our other most favorite build is the delightful prank build which makes the hammer unliftable except by the recognized owner.

As Entries Close, Finalists Polish Their Projects

There have been five challenge rounds of the Hackaday Prize and we’ve seen more than 1000 entries. From each round, 20 finalists were chosen who were awarded $1000 each but we’re just getting started. The top five prizes totaling $75,000 still remain.

A panel of fantastic Hackaday Prize Judges will begin reviewing the final round projects on October 21st. Finalists are continuing to refine their projects since being selected, adding project logs, a bill of material, design files, and a project video. This all leads to the awarding of the Grand Prize on Saturday, November 11th at the Hackaday Superconference.

Hackaday’s Open Hardware Summit Experience

Last week was the Open Hardware Summit in Denver Colorado. This yearly gathering brings together the people and businesses that hold Open Hardware as an ideal to encourage, grow, and live by. There was a night-before party, the summit itself which is a day full of talks, and this year a tour of a couple very familiar open hardware companies in the area.

I thought this year’s conference was quite delightful and am happy to share with you some of the highlights.

Review: New 3G and Cat-M1 Cellular Hardware from Hologram

In July we reported on the launch of the Hologram developer program that offered a free SIM card and a small amount of monthly cellular data for those who wanted to build connectivity into their prototypes. Today, Hologram has launched some new hardware to go along with that program.

Nova is a cellular modem in a USB thumb drive form factor. It ships in a little box with a PCB that hosts the u-blox cellular module, two different antennas, a plastic enclosure, and a SIM card. The product is aimed at those building connected devices around single-board computers, making it easy to plug Nova in and get connected quickly.

This device that Hologram sent me is a 3G modem. They have something like 1,000 of them available to ship starting today, but what I find really exciting is that there is another flavor of Nova that looks the same but hosts a Cat-M1 version of the u-blox module. This is a Low Power Wide Area Network technology built on the LTE network. We’ve seen 2G and 3G modems available for some time now, but if go that route you’re building a product around a network which has an end-of-life concern.

Cat-M1 will be around for much longer and it is designed to be low power and utilizes a narrower bandwidth for less radio-on time. I asked Hologram for some power comparison estimates between the two technologies:

AVERAGE current consumption comparisons:

Cat-M1: as low as 100 mA while transmitting and never more than 190 mA
Equivalent 3G: as high as 680 mA while transmitting

PEAK current consumption comparisons (these are typically filtered through capacitors so the power supply doesn’t ever witness these values, and they are only momentary):

Cat-M1: Less than 490 mA
Equivalent 3G: As high as 1550 mA

This is an exciting development because we haven’t yet seen LTE radios available for devices — of course there are hotspots but those are certainly not optimized for low power or inclusion in a product. But if you know your ESP8266 WiFi specs you know that those figures above put Cat-M1 on a similar power budget and in the realm of battery-operated devices.

The Cat-M1 Nova can be ordered beginning today, should ship in limited quantities within weeks, with wider availability by the end of the year. If you can’t get one in the first wave, the 3G Nova is a direct stand-in from the software side of things.

I suspect we’ll see a lot of interest in Cat-M1 technology moving forward simply because of the the technology promises lower power and longer support. (I’m trying to avoid using the term IoT… oops, there it is.) For today, let’s take a look at the 3G version of the new hardware and the service that supports it.

Get Hands-On at Supercon: Workshop Tickets Now Available

Build something cool and pick up new skills from the workshops at the Hackaday Superconference. Last week we announced all of the talks you’ll find at Supercon, and starting today you can reserve your spot at one of the workshops.

You must have a Superconference ticket in order to purchase a workshop ticket; buy one right now if you haven’t already. You can get mechanical with Haptics and Animatronics, take your product design from schematic to PCB and enclosure, brush up your embedded development on several choices of platform, make cell towers do your bidding, or dump way too many volts into a block of wood.

Space in these workshops is limited so make sure to sign up before all the seats are taken. The base price for workshops is $10 (basically a “skin in the game” price to encourage those who register to show up). Any tickets priced above that base is meant to cover the material expense of the workshop. Here’s what we have planned:

Embedded Programming with Black Magic and the Lights On

Piotr Esden-Tempski

Sunday Afternoon

Embedded systems programming has earned a bad reputation of being difficult to master. Especially in the open-source world, most people associate it with cut and pasted code that is difficult to debug. The usual tools we have to debug embedded systems are a blinking LED and, if we are lucky, printf statements through a serial port. In this self guided workshop we will show you how easy it can be to have full insight into your microcontroller using fully open source tools that are on par with expensive proprietary closed-source solutions.

Fun with High Voltage

Will Caruana

Sunday Morning

This workshop is about making Lichtenberg figures. A Lichtenberg figure is a piece of art though the multiplication of a few thousands of volts to burn wood. We will cover the science behind this art form as well as the safety and lastly we will be getting hands on experience in being able to using high voltage transformers to make these burnings into wood and make coasters you can take home.

Designing Electronic Textures

Noah Feehan

Sunday Afternoon

Participants will learn the physics behind electrovibration, and then get to play/design for it using a new open-source board called WEFT. After the workshop, you’ll know how to deploy electrovibration in your projects, and understand the feeling of different waveforms.

End to End Product Design with Eagle and Fusion 360

Matt Berggren

Saturday Morning

In this session, we’ll take you end to end, from building a new schematic, simulating a circuit using EAGLE’s built-in SPICE simulator, laying out a PCB, generating mfg files and include some tips & tricks for milling boards and making stencils. We’ll also take you thru the link between electronics and mechanics using Fusion360. Alongside EAGLE we’ll build an enclosure and generate the mfg outputs for your mechanical design (CAM, 3D prints, etc). We’ll look at library management across electronics and mechanics and bidirectional synchronization between both of these domains. This is more than an intro, as Matt’s always good for some essential, oft-missed background and tips with EAGLE you might never have known otherwise.

AVR® MCU Effortless Design Workshop: Prototyping with Sensors and BLE

Bob Martin, Senior Staff Engineer

Sunday Morning

This hands-on training session will walk you through how to develop an embedded sensor node prototype with Bluetooth® Low Energy (BLE) connectivity. You will speed through configuration of the AVR microcontroller, sensor interface and communications interface setup by using Atmel Start, a graphical programming interface. This tool will generate libraries with simple APIs so you can spend time working on your solution instead of messing with registers or communication protocols.

Rapid Prototyping and Linux Kernel Development with the PocketBeagle® Platform

Robert Nelson

Saturday Afternoon

The newly introduced PocketBeagle® is an ultra-tiny-yet-complete Linux-enabled, community-supported, open-source USB-key-fob computer. By leveraging the Octavo SIP, the PocketBeagle offers complete BeagleBoard functionality and includes 512MB DDR3 RAM, 1-GHz ARM Cortex-A8 CPU, 2x 200-MHz PRUs, ARM Cortex-M3, 3D accelerator, power/battery management and EEPROM. The board offers lots of GPIOs, on board peripherals and various expansion capabilities via multiple headers and the Mikroelektronika click board interface. During this course you will learn about pin configuration, how to create a Linux distribution, reconfiguring io on the fly and how to leverage expansion modules. Attendees will leave with their very own PocketBeagle and a couple other surprises as well.

Cellular Connectivity for Your Next Hardware Project

Ben Strahan and Chris Gammell

Saturday Afternoon

Your project shouldn’t be constrained by the range of a WiFi signal. This workshop will show you how to connect to cellular towers via a serial link, get connected into the cloud and reliably start transmitting data. This workshop is suitable for people just getting started in the firmware ecosystem up through advanced firmware engineers. Advanced members of the workshop will have the opportunity to hack their conference badge to connect to cell towers. Sign up for this workshop to add another connection method to your hardware development toolbox.

An Introduction to Animatronics with Laser Cut Tentacle Mechanisms

Joshua Vasquez

Saturday Morning

Animatronics are way cool, but the hacker community rarely ventures farther than a few hobby servos and “dem-blinkin’ LEDs.” In this workshop, I’ll get you cozy with tentacle mechanisms that you can build with just a laser cutter and a few hand tools. There are three big takeaways from this workshop. We’ll build up a two-stage controller reusable in other projects, muscle up our vocabulary of off-the-shelf parts for cable mechanisms, and discover a few laser-cut design techniques.

Superconference workshops tend to sell out extremely quickly. Don’t wait to get your ticket.
