The inner machinations of the mind of cryptocurrency markets are an enigma. Even traditional stock markets often seem to behave at random, to the point that several economists seriously suggest that various non-human animals might outperform one market or another just by random chance alone. The classic example is a monkey picking stocks at random, but in the modern world the hamster [Mr Goxx] actively trades crypto from inside his hamster cage.
[Mr Goxx]’s home comprises a normal apartment and a separate office where he can make his trades. The office contains an “intention wheel” where he can run in order to select a currency to trade, and two tunnels that [Mr Goxx] can use to declare his intention to buy or sell the currency he selected with the wheel. The wheel is connected to an Arduino Nano with an optical encoder, and the Nano also detects the hamster’s presence in the “buy” or “sell” tunnel and lights up status LEDs when he wants to execute a trade. The Nano also communicates with an intricate Java program which overlays information on the live video feed and also executes the trades in real life with real money.
Live updates are sent directly both on Twitter and Reddit, besides the live Twitch stream of [Mr Goxx] we linked above. The stream only shows his office and not his apartment, and he’s mostly active at night (Berlin time). But we can’t wait for his random walks to yield long-term results which can be analyzed for years to come. In the meantime we’ll see if others have been able to make any profits in crypto with any less-random methods.
Join us Wednesday at noon Pacific time for the From Software to Tindie Hack Chat!
Brian Lough has followed a roundabout but probably not unusual route to the hardware hacking scene. Educated in Electronic and Computer Engineering, Brian is a software developer by trade who became enamored of Arduino development when the ESP8266 hit the market. He realized the microcontrollers such as these offered incredible capabilities on the cheap, and the bug bit him.
Since then, Brian has fully embraced the hardware hacking way, going so far as to live stream complete builds in a sort of collaborative “hack-along” with his viewers. He’s also turned a few of his builds into legitimate products, selling them on his Tindie store and even going so far as to automate testing before shipping to catch errors and improve quality.
Please join us for this Hack Chat, where we’ll discuss:
- How software hacking leads to hardware hacking;
- The creative process and how live streaming helps or hinders it;
- The implications of going from project to product; and
- What sorts of new projects might we see soon?

Over the weekend, the last available tickets to the Hackaday Superconference vanished. This will be the fullest, most exciting, hack-packed Supercon ever.
We’ve always had a stunning slate of speakers. It’s hard to objectively say we will top previous years, but yes this collection of talks is an insane concentration of hardware speakers that tops anything we’ve seen before. You can’t look at the schedule without feeling an electric jolt of excitement. The good news is you can still get in on those talks. Bookmark this Hackaday Superconference Live-Stream which begins at 10 am PDT on Saturday, November 3rd.
Of course, talks are only one component of Supercon. The secret sauce has always been the people at the con. If you’re not joining us, we still need you to take part. There is a conference chat on Hackaday.io and all are welcome. Pop in and visit with people at the con, and others around the globe who wish they could have made it in person.
Make sure you’re on the live stream Saturday evening to watch as the Grand Prize is presented on stage during the Hackaday Prize Ceremony. Follow along throughout the weekend on social media with the #Supercon tag. Pop into the chat and ask for updates on badge hacking, the SMD Soldering Challenge, and all of the other shenanigans that make Supercon super. We look forward to seeing hundreds of you in Pasadena starting this Friday, and thousands of you online through out the weekend!
Have you ever been seduced by a claw machine in an arcade, only to have your hopes of a cuddly toy dashed as it fails to hang onto your choice? Then you’re in luck, because now you can play to your heart’s content online. [Ryan Walmsley] wants you to control his Raspberry Pi-driven claw machine.
Hardware-wise he’s replaced the original 8052 microcontroller and relay control with the Pi and a custom H-bridge PCB. We particularly light the warning: “Highish voltage”, and we feel it should appear more often. There is some code in his GitHub repository, but we suspect it doesn’t have everything.
We had a lot of fun digging into the documentation on this one. From his initial thoughts through some prototyping and a board failure, to the launch of the online version and finally a run-down of how it all works, he’s got it covered.
Sadly the machine itself isn’t online all the time, it seems to be only online when [Ryan] is at home, so if you live on the other side of the world from his British base you may be out of luck. Fortunately though his previous live streams are online, so you can see it in action on a past outing below the break.
Of course what kind of swag do you load up in a claw machine like this one? On his Twitter feed we’ve seen tests of the aliens from Toy Story (who start their existence in a claw machine so quite fitting). The majority of items show in is recorded games — now numbering over 2000 — have been our beloved companion cube.

[Imetomi] found himself salvaging a camera from a broken drone when he decided to use it in a new project, a tracked robot with a live video feed from the mounted camera.
… I had a cheap Chinese drone that was broken, but its camera seemed to be operating and when I took apart my drone I found a small WiFi chip with a video transmitter. I (decided) that I will use this little circuit for a project and I started to buy and salvage the parts.
Being a tracked robot, it can negotiate most types of terrain and climb hills up to 40 degrees. It is powered by two 18650 lithium-ion batteries with a capacity of 2600 mAh and the remote control is based on the HC-12 serial communication module. You can control it with a joystick and watch the camera’s live-stream in a virtual reality glass. That’s pretty neat but it’s not all.
[Imetomi] also used a hacked Nacomimi Brainwave Toy to make a brain controlled version of his robot. The brainwaves are detected using sensors placed on the scalp. To actually control it the operator has to focus on the right hand to move right, focus on the left hand to move left, blink to move forward and blink again to stop. There is also an ultrasonic sensor to help navigation so the robot doesn’t bump into things. It’s not very precise but you can always build the joystick version or, even better, make a version with both controls.

[CNLohr] needs no introduction around these parts. He’s pulled off a few really epic hacks. Recently, he’s set his sights on writing a simple, easy to extend library to work with the HTC Vive VR controller equipment, and in particular the Watchman controller.
There’s been a lot of previous work on the device, so [Charles] wasn’t starting from scratch, and he live-streamed his work, allowing others to play along. In the process, two engineers who actually worked on the hardware in question, [Alan Yates] and [Ben Jackson], stopped by and gave some oblique hints and “warmer-cooler” guidance. A much-condensed version is up on YouTube (and embedded below). In the links, you’ll find code and the live streams in their original glory, if you want to see what went down blow by blow. Code and more docs are in this Gist.

We have an amazing line-up of talks for Hackaday | Belgrade, Saturday April 9, in Belgrade, Serbia. The talks have been sold out for weeks. You can still get a ticket to the night’s concerts if you’re in the area. Either way, the big news this morning is that we will stream all of the talks live!
Live-stream links will be posted on the conference page as soon as we get them. You should also join the chat over on the Hackaday | Belgrade project page. Just click the “request to join this project” button in the upper right. Do that right now.
There are a ton of great speakers, check the poster below. I’m excited to hear Mike Harrison (mikeselectricstuff) speak about his journey down the rabbit hole of video projection tech, Phoenix Perry’s talk on Forward Futures, Voja Anotic’s talk about the hardware badge, Peter Philip’s talk about reinventing VHDL, and pretty much all of the rest too! From the Hackaday crew you can watch Sophi Kravitz give a talk on her shutter glass project, Chris Gammell will be talking Top Down Electronics, and I will end the 8-versus-32 argument once and for all (yeah right!).
While you’re listening to the talks, why not try your hand at badge hacking. You don’t need any hardware, you can use the emulator to try out your hacked code right now your own computer. We’ll be sending out prizes for the best entries and there are only a handful so far.
You do not want to miss these talks! If you don’t believe me, check out the talks from SuperCon last November and you’ll be convinced — Hackaday conferences provide the best collection of hardware talks anywhere.
