    Hacklet 37 – Nixie Projects | Hackaday

    hackaday.com 06 Mar '15, 3pm

    Nothing quite beats the warm glow of a tube. What better way to enjoy that glow than to use it to read numbers? Nixie tubes were created by Haydu Brothers Laboratories, and popularized by Burroughs Corp in 1955. The name comes from NIX I – or “Numeric Indicator eXperimental No. 1″. By...

    hackaday.com 06 Mar '15, 3am

    FormLabs resins operate best between the comfortable temperature range of 18 – 28°C (64 – 82°F). For many of us experiencing the chillier weather these days, our garage workshops can easily drop below those temperatures and cause our prints to fail. Rather than hunker down for the fre...

  • Revive The Demoscene with a LayerOne Demoscene Board | Hackaday

    hackaday.com 05 Mar '15, 6pm

    As someone who was part of the demoscene back in the days – and still is to a certain degree today – I fail to see how this is going to appeal to more than perhaps a handful of happy campers? Sweden’s demoscene for everything Commodore (or anything hackable) back in the days were mass...

  • Using Cheap Displays With The Raspberry Pi | Hackaday

    hackaday.com 05 Mar '15, 12pm

    I’m looking into using a Pi to control a robot if I ever get around to building the robot :P I honestly thing a micro controller wouldn’t quite be able to handle what I plan on having it doing and a laptop would probably be a bit bulky. Course it is in theory large enough that the ext...

  • Deconstructing PCBs

    Deconstructing PCBs | Hackaday

    hackaday.com 05 Mar '15, 9am

    The surest way to reverse engineer a circuit is to look at all the components, all the traces between these components, and clone the entire thing. Take a look at a PCB some time, and you’ll quickly see a problem with this plan: there’s soldermask hiding all the traces, vias are under...

  • Caramelizing Sugar With a Laser

    Caramelizing Sugar With a Laser | Hackaday

    hackaday.com 05 Mar '15, 3am

    Checking Populated PCB Clearance with a 3D Printer | Hackaday

    hackaday.com 05 Mar '15, 12am

    Laying out one PCB, sending it out to a fab, stuffing it with components, and having the whole thing actually work when you’re done is a solved problem. Doing the same thing and having it plug in to another PCB… well, that’s a bit harder. Forget about building a PCB and having it fit ...

  • Midwest RepRap Festival, March 20-22nd | Hackaday

    hackaday.com 04 Mar '15, 9pm

    Nixie inspired 7 segment display | Hackaday

    hackaday.com 04 Mar '15, 6am

    The supply of Nixie tubes from east European stock piles is still enough to keep their prices down. But once those start dwindling, prices will move north. Besides, if you want to use them, you need to work with high voltage supplies and worry about not getting zapped while trying to ...

    Introducing the Solder Sucker 9000 | Hackaday

    hackaday.com 04 Mar '15, 12am

    Using a regular plunger style solder sucker is tedious at best, and usually not that effective. If you’re trying to salvage components off a PCB, sometimes it can take longer than it’s worth to do — short of reflowing the entire board that is! But what if you had something to desolder...

    hackaday.com 03 Mar '15, 12pm

    Origami cranes are cool, but do you know what’s cooler? Origami cranes dancing to the beat. That’s the challenge [Basami Sentaku] took on when he created Dancing Paper (YouTube link). You might remember [Basami] from his 8 bit harmonica hack. In Dancing Paper, paper cranes seem to dan...

  • BeagleSNES for Game Boy, Game Boy Advance, NES, and – yes – SNES | Hackaday

    hackaday.com 03 Mar '15, 9am

    By far the most common use for the Raspberry Pi is shoving a few dozen emulators on an SD card and calling it a day. Everybody’s got to start somewhere, right? There are other tiny, credit card-sized Linux boards out there, and [Andrew] is bringing the same functionality of the Raspi ...

    Fix a Broken DS by Removing a Screen | Hackaday

    hackaday.com 03 Mar '15, 6am

    There are apparently a lot of broken Nintendo DS Lites out and about on eBay, and [Fede] has gotten his hands on one. His idea was to essentially turn one of these DS Lites into a SS (single screen?) (.es, Google translate ) by modding the case, and he’s done it with pretty spectacula...

    Running vintage console emulators on a Raspberry Pi seems to be the thing all the cool kids are doing. The coolest RetroPie builds take a vintage console – usually of the Nintendo genus – stuff a Raspi in there somehow, and Bob’s your uncle. [Phil Herlihy] over at Adafruit is throwing...

  • Building a Transcutaneous Electrical Nerve Stimulation Device in a Weekend | Hackaday

    hackaday.com 02 Mar '15, 9pm

    Now *that’s* contributing something to HAD in a meaningful way! Drop insults, offend large groups of people without meaning to (I’m giving you the benefit of the doubt there), say nothing useful, and try to rickroll people in a method so poor that it doesn’t even work (oops!). I, for ...

    hackaday.com 02 Mar '15, 6pm

    The Red Pitaya is a credit-card sized board that runs Linux, has Ethernet, and a good bit of RAM. This sounds a lot like a Raspberry Pi and BeagleBone Black, but the similarities end there. The Red Pitaya also has two RF inputs, two RF outputs, and a load of digital IOs, all connected...
