Hacker’s Phone Charger

This project starts a few months ago when one of our members was putting together a class for a girl scout troop. He was teaching them using adafruit trinkets and needed a fairly powerful 5v supply to power them. His Solution was to use some old rear pci slot mounted USB jacks, similar to the image bellow, connected to the 5v supply line of a PC power supply.

USB PCI Header

One day at the space someone needed to charge their phone so they plugged it in to the jack connected to the power supply. I liked the idea and decided to take it a bit over the top. I used openscad to create a box to hold all the USB jacks along with binding posts that connect to the +12v, +5v, and +3.3v coming out of the power supply. I printed the top and bottom of the box on the 3d printer. and now have an over-the-top hacker phone charger, raspberry pi and everything else power station. Two of the PCI USB slots had status LEDs on them. I added an attiny85 to blink them around in a cycle as just a fun extra feature.

Without further ado here is the finished product.

Standing Desk Mod

Standing desks have become pretty huge lately. They are said to be a great way to avoid the long hours of sitting that accompanies many jobs. After using one for a few weeks when I was working in Germany I understood the hype and when I got home I had to have one for myself.

The first thing I thought was that I didn't want to just make a tall desk. That would have made it so I was always stuck with a standing desk. Sometimes you need to just sit down. When I looked for pre-made convertible standing desks I found out that they were ridiculously expensive. I knew I needed to make my own desk or modify the one I had.

I racked my brain for a while thinking what to do. I thought of some ideas that would put a new top on my desk that could be lifted but that seemed like a big task. Then I came across an eBay listing for 18 inch stroke linear actuators that run at 24 volts and could lift 600lbs. They were being sold by surpluscenter.com. Each actuator was about $45.

Using 4 linear actuators, a 24V linear power supply, an arduino, a relay board with 8 relays, and a few other components I created a convertible standing desk.

Check out the video below for a tour of the desk.

Should a Maker go to a Hackathon?

We invited Tim Lytle of LV Hack (among other things) to share his argument for why a hardware hacker should join an event that is traditionally for software hackers. They're really interested in having more hardware guys around to bring new ideas and make new things possible. There is some fun to be had! -- Josiah


What's a Hackathon?
First things first: A hackathon is an event - generally a few days on a weekend - that brings people together to build interesting things, all the while learning about new technology and sharing experiences. People may 'hack' on something: take a technology, exsisting product, or open source software, and repurpose it into something else, add features, or explore new uses. Other's may 'hack' something together: take various building blocks, APIs, hardware platforms, and create something completely new and unique.

What's a Hacker, and a Hack?
It's probably safe to say that most makers wouldn't raise an eyebrow at those terms - but in case the definition is a bit fuzzy, a hacker is simply someone really good at solving problems and overcoming limits in ways that may not seem obvious to most. Paul Graham has said that a hacker is "someone who can make a computer do what he wants—whether the computer wants to or not." And a hack is the imaginative, clever, and perhaps crafty output of that hacker. "Whether the result is a quick-and-dirty patchwork job or a carefully crafted work of art, you have to admire the cleverness that went into it" is how the Jargon file distils the meaning.

If you think that sounds a little like the software version of a maker - well, you'd be right.

But hacking is not really limited to software, and making is not really limited to just the things we can physically touch - so I'd venture to say that a hacker and a maker are pretty much the same thing.

But Why a Hackathon?
That's a fair question. Whether you're tinkering on a robot (or laser), working on some software project, or building something with a microcontroller - there's weeknights after work, open hack nights at the makerspace, and every other weekend. What makes a weekend hackathon so different?

It's for all those ideas that you're not working on yet. The ones that would take more than just a few nights to test the potential, or that need another set of eyes, a second pair of hands, or a few more heads to really figure out. And even when it's not your idea, it's a great opportunity to see what's bouncing around in someone else's head, and end up making something that inspires your next idea. 

The people you meet at a hackathon can become lifelong friends, partners on projects, and even at times the team that takes a hack of an idea, and turns it into something much bigger.

And while traditionally people think of hackathons as a place for software developers, that distinction is becoming less and less true. From software to embedded devices to mechanical engineering - we've seen a variety of hacks at our hackathons over the past few years. And we expect even more variety this time around, as our venue is the Wilbur Powerhouse with a assortment of printers and prototyping tools.

So yes, a maker should definitely go to a hackathon - and fortunately for you, there's one going on in just a few weeks. See you there?

Class: Paper Craft for Beginners

Join us this Thursday (July 19th) for our Paper Craft for Beginners class held at the Hive4A makerspace (905 Harrison St., Allentown) from 7-8:30pm.

Cost is $5.00 per participant.

Children must be accompanied by an adult as we will be using X-acto knives.

Please register for Paper Craft for Beginners on our WePay page.

This isn't your grandma's origami!  ...actually its just cutting and gluing from elementary school taken to a whole new level.  The basic technique is the same for any paper craft model.  Templates for models to practice on will be available as well as some more advanced models that will probably take more time then we have for the class.

Ellis and Mark will demonstrate their Paper Craft techniques with tips and tricks and then help you figure out what your personal technique is.  There will be an array of glues and miscellaneous tools available for you to try and see what works best for you.

With just paper, there are so many things you can bring to life in 3D.  Among the more common creations are:

  • Scale Models
  • Props
  • Halloween Masks & even entire Costumes
  • Oversize Game Pieces
  • Decorations
  • Cards
  • Prototyping for materials that are more expensive or harder to work with
  • The first process for custom Halo Armor is Paper Craft

New Profile Posted to SchoolFactory

If you are just getting involved, been thinking about visiting or simply are curious, this write-up over at The Space Federation website might be worth reading over to get an idea of what the association is between Hive 4A and Make Lehigh Valley along with some other details about us as a group, what some of our next steps are and some of what we envision for the future.

We are Make Lehigh Valley, a community of hackers, makers and artists who meet and use the Hive 4A Hackerspace facility. The space is provided by Hive 4A which also provide a co-working space across the hall in an old Mac Truck factory in a facility they call Bridgeworks. Both are owned and operated by the Allentown Economic Development Corporation. They are interested in promoting creativity especially around manufacturing in Allentown and generally in the Lehigh Valley of Pennsylvania. The same facility has been operating as a manufacturing business incubator for many years. Their are great opportunities for a maker to start ...

Saturday 19th: 7hr Open Hack

We'll be opening up the hackerspace for an unprecedented 7hrs this Saturday!

We'll be opening for the Saturday (19th) open hack from 11a to 6pm. That's this Saturday as in a few days away.

Flying Platforms
I found out my neighbor has a business called Club Heli selling RC helicopters and parts. He's hoping to make it out. I told him we've been chatting about helicopters and such so made a special point of inviting him. He told me he's not looking for advertising so you know these aren't paid links, just notes about an interesting resource to be aware of.

Bring a Friend
As always, feel free to bring a friend, cousin, brother-in-law, uncle, neighbor, wife, kids or whomever.

Bring a Project
Also, bring out a project to work on. We have a good bit more space. If you stop by the Radio Shack on the way, mention Make Lehigh Valley. 😉

Feel free to bring something to show off and something to work on. If we have enough stuff to show off, I'll get a table setup for that stuff so people stopping by can browse over things. We can have our own super mini maker faire.
