Two-by-Four Block Table with Hairpin Legs

by Aaron

Finally finished the butcher block style table made from 2x4's and glue. I jointed and planned a pile of 2x4's together at hack.rva, then glued them using every clamp I could find in the workshop.

Tried making my own hairpin legs with rebar, but didn't have much luck. So Matt ended up making me some. The extra table on top was a result of making the original too long, so I loped off the end and made a second smaller table.

The cat feels that he helped, so now lives on top of this. Not sure I'll ever actually get to use it.

Bandsaw thy Box

by Aaron


We have a box problem - we can't seem to stop making them. Michael has taught many others to make these sweet boxes using the bandsaw (thus the name "Bandsaw Box" (google it - they're everywhere). Here's a link to the full project. Let's not even get started on "flocking the box".

Printer Stand from Scratch

by Aaron


This was a pile of wood. Now it's a custom-built printer stand and printer accessories wonder furniture. Being able to build things exactly the size and way you want them is a common reason for being a maker. Epitome of thus. Go here for complete build explanation.

Scanning with 3D Systems

by Aaron


Neal and I were visited by teacher and STEAM advocate Jeff to show us a some 3D scanning technology from 3D systems. We scanned the frame Neal's electric motorcycle project and the head of the good looking chap above as well as various items and people within reach.

With the motorcycle frame, the digital model is being used to create mounting plates with proper offsets for the motor. There's just not enough clearance with the shaft length to get the sprocket inline, so an intermediate gear will be used to transition between the motor and the wheel. Getting all the correct measurements within the irregular shape of the frame can be a challenge using traditional measuring, thus the scan.

Jeff also talked about how they use the 3D Systems "Sense" scanner to teach in classrooms. Metrology, or the science of measurement, is a common method.  Students take models and measure them - then extrapolate that information to fractions and other fundamental math concept goodies. He also touched on the 3D Systems modeling tools they use such as Geomagic Freeform and Cubify Invent. As a side note, he also showed us Microsoft's Kodu (which I seem to be the last person in the world to know about), a very clickable game making software for youth that was a lot of fun.

Tap Handles

by Aaron



Built some fun tap handles on a lazy satruday evening. Used the CNC Router for the 'F' and the laser cutter for the detail markings. Started with chair leg type parts for the round parts. See more build pics here.

Game of Groans - Shuffle Board Table Build

by Aaron

A shuffle table was made! Dustin and Co built this in a single day at hackrva. It now lives in his brothers house for many nights of metal puck sliding fun(?).
I was skeptical of the whole concept of shuffle board until I saw this video of majestic sport feat. Also, that guy's nickname is "roadhouse". I'm just not living.

We Don't Live in Monolithic Worlds: Agency, Collaboration, and Company in Fails

Once upon a time there was a woman named Red Burns.  She’s sometimes called the Godmother of Silicon Alley.  For someone so influential in the arts and tech, it’s hard to find good information about her.  She didn’t have a Twitter account.  There was no personal Facebook account.  She didn’t tend a digital space for the burping out of meaningless platitudes on start-ups or the saving graces of technology.  She didn’t write a memoir.  The most prevalent  sources of information on Red seem to be obituaries and memorials.   

How can there be so little easily attainable information on someone so influential?   

Stories of Red’s impact come from graduates of NYU’s ITP program, which Burns co-founded.  Memories of Red’s influence come from artists and technologists.  Usually there is a common thread in the stories and memories: it’s not about the technology.  Do everything for people.  

The Red Burns legend goes something like this: It’s the late 60s.  Red Burns, a filmmaker, is handed a Sony Portapak camera.  With this mobile video camera in hand, she realizes the impact the technology will have on an individual’s ability to tell stories through documentary.  In Big Bird & Beyond: The New Media and the Markle Foundation Red says, “It was one of those epiphanous moments… I said to myself, this is going to have some impact.  It was just incredible that nonprofessionals could make their own documentaries… Now, I wondered, how can they do it?”

Just a few years later, Red co-founded the Alternative Media Center at New York University.  The Alternative Media Center provided training and access to equipment.  McCandlish Phillips writes in “TV of the People Operating on Cable,” his 1971 New York Times article, the media center was “... devoted exclusively to cultivating cable television as an outlet and resource for local, nonprofessional communicators.”  In McCandish’s article Red explained that the media center did not offer college classes or accept students into a program.  Instead, the staff and faculty of the Alternative Media Center offered weekly training sessions and eventually equipment “for groups interested in ‘going on the cable.’”  The Alternative Media Center provided a space, staff, and resources to carry out Red’s vision: media created by the community.  

Communities and organizations in towns and cities like Reading, PA, Charleston, WV, Tullahoma, TN, and Cape May, NJ received training and support from the Alternative Media Center and produced documentaries on black lung and extensive on-air programming planned, produced, and filmed by senior citizens in Reading.  

The authors of Big Bird & Beyond explain that Red saw public access cable as a platform “which gave ordinary citizens the ability, for the first time, to take to the airwaves as writers, editors, producers, actors, and social and political commentators.”  

Citizens were makers of their own media.  And as you know, agency goes a long way.  

Red believed that public access cable provided “immediate and unrestricted space” for community programming and public service.  

By the end of the 70s, the Alternative Media Center morphed into NYU’s Interactive Telecommunications Program (ITP) in the Tisch School of the Arts.  Red co-chaired the department, which accepted students with backgrounds in dance, math, non-profit work, engineering, computer science, animation, fashion, industrial design, and more.  She once said in an address to ITP students, “... we don’t live in a monolithic world.  Our signature is collaboration--not competition.  

ITP’s alums work for Google, Apple, Disney, Microsoft, and a host of start-ups.  Graduates designed exhibits for the 9/11 Memorial Museum and the metro card vending machines for the New York subway.  

Many of Red’s philosophies and practices are echoed in the maker movement and maker/hackerspaces.  Everyone is welcomed regardless of background, degrees, or training.  Tools are offered, but most importantly so is training and access to expertise or at least there’s company when fumbling through Youtube tutorials and mistakes.

Hacker Lights - Aerial Emanations to Confound and Perplex

by Aaron


Have you ever wanted to make complete strangers or dear friends believe the alien invasion is at hand?

Hacker Lights, by HackRVA member Andy, is a control box especially designed for freaking people out. Or, specifically, programmable/addressable LEDs for cool patterns on your UAV's. A super FEATURE is that those patterns can be designed and programmed to the control box using the online app he created on his website.

Pimp our cups

Wine & Weld is coming up, and the only things that will make the day complete are some diamond encrusted wine glasses for the pre-welding post-welding celebration. However, if you're on a budget rhinestones, stickers, gems, and paint will have to do. 

Wetlands Research Using Remote Technology


Daniel made an awesome wetlands science project that was at least in part completed at HackRVA. Check out the featured main-page blog post for more details.

Things Now Attached to the Wall: Part 1 of 134

There are many new things attached to the wall, providing a stability completely unexpected from Aaron updating this blog. This ongoing series will examine many of the things stuck to the walls or close to the walls of The Space and examine their intrinsic beauty.

Exhibit one: Aaron likes to take pictures with his iPod. As other technology confuses and angers the great redheaded beast, he is allowed to grunt and scrape his paws against the screen to make the pictures happen, saving us a rage-fueled rampage where he tears off limbs in the same manner as an enraged orangutan. To that end, a simple, 3D-Printed solution with off-the-shelf hardware was developed to allow him to bang hammers against sensitive, printed boards on camera while not having to destroy (or lose once again) his iPod.


If you find his silly iPod left haphazardly in a place it doesn't belong, this is the place to put it. Also, it's a 3D range, magnetic anchored (or weight anchored if on a table) holder to direct your camera for pics or video.

The Greatest Invention

Fire, the wheel, and the Sisyphean drudge of maleficent need, as the philosopher Heidegger might label as the always-already of human is-ing, causes mankind to forge forward in the noble endeavor of creating that which fills the hole in our creative and most base (and basic) of needs. Such a man is among you in the living flesh, dropping the proverbial manna of creativity upon your brow in the manner of what may be the greatest invention of our generation, of our time: the post in a bucket.

Here, it is being used to hang wires for spray-painting metal:
Do you See?

It has been used to hold up a tarp to shield your virgin eyes from the deadly light of welding. As the tarp was up, you didn't, but do you See?

Its uses are multifaceted, its angles more intricate in the Euclidean simplicity than a careful study of the multifoliate rose.

I present to you the Post in a Bucket (tm) (patent pending).

Back Space Pedal

by Aaron
This is a gaming pedal (as in driving a car) that has been converted into a human interface device which moves cursors in reverse when stomped upon. In other words, a back space pedal.  It utilizes a salvaged PS/2 keyboard circuit for the interface.
