Heya. starting a small hackerspace with some guys.
I’m the resident electronics dude, so i’ve taken it upon myself to get a semi-decent lab going.
I already got a fairly decent digital soldering station there.
However, at work we have these super sweet Hakko vacuum-desolderers and i’m absolutely addicted.
A sucker would be a blessing when salvaging parts and such.
Enter the old solderstation from way before i was ever employed at my company. donated to me.
This combi rig seemed decent for its age but the pump was terrible. if the legends around the office are true, it has always been terrible.
My brother, TinkarLjarl suggested i try this pump. a 350w mains driven vaccuum pump!.
Never thinking i’d actually use it, i went along and hooked up the hose and he plugged it in while i tried to desolder some components.
A bit loud, but it worked like a charm!
Seeing as these pumps have never been of use to the company, and my boss never explicitly saying no, I got to work after hours at the office.
The carrier plate for the pumps looked useful for making this beast more manuverable, so i got one pump off..
..and bolted the station snugly it its place.
A quick relay board for driving the thing, triggered by the old pumps 24v. fuse for good measure.
Cut open a slot for the vacuum and pump mains with a hacksaw. ugly but functional.
Works good. the relay sparks like crazy so i might go SSR when the contacts go bad.(they will!)
And there you have it! weighing in at 18Kg its not for lugging around.
A bit of a pain to get to the hackerspace.
going from 8w to 350w will put on some weight.
Intel has a Perceptual Computing Challenge going for their kinect-like webcam and the Space Invaders project a friend and I’ve been developing got through to the second stage. This is a project that we have tried making on several platforms and interfaces, but the original idea persists: remake the classic game in 3D, where you are the controller and the invaders and their space is as big and immersive as possible. Below a short video from the beta.
And here is a video from our alpha stage with the kinect a year or two ago.
Hey. First post here on the page.
This project is fairly simple but i find it useful.
I did this early December after i found an orphaned 20pin ZIF socket at work and figured i wanted to program 2313′s.
It is just a permanent Arduino ISP programmer with 3 4052 multiplexers to switch between the pinouts for the attiny85,84 and 2313.
The 4052 address pins are pulled down and set with a sp3t switch. I’ve seen shields using 3 sixway dipswitches. this seemed impractical to me.
My nano is mounted on headers and not modified in any way. I might need it for something else one day.
The leds are heartbeat/error/programming indicators
Not as pretty underneath, i used this stripboard that is cut every three holes. i find these practical when working with ic’s.
The predecessor was an old shield with ic sockets for 85 and 84.
Nest step adding a six ISP header so i can mess with ISP programming of atmega8s and other avrs by converting the arduino files to hex and programming through AVRdude
Got a request from the Brage Theater in Drammen / Norway. They wanted a weird contraption to visualize the dream of a 12 year old boy. A great invention that would change the world. They gave me a good budget and mostly free will so I ended up with this:
We should ask for some Norwegian cultural-petroleum monies and go to Burning Man this year…
Our story begins in Melanesia during World War II. Thousands of American GIs suddenly descended on this South Sea island chain, bearing with them unimaginable riches: magical foodstuffs that never spoiled, inconceivable power sources. Just as abruptly the troops departed, leaving only broken, rusted Jeeps, crumpled beer cans, and the memory of Spam. To the astonished eyes of the natives, this was a miraculous occurrence, and they yearned for the return of abundance. Accordingly, they built totemic sky-craft in an attempt to summon back these Visitors and their legendary leader, the man the Melanesians called John Frum. They had formed a Cargo Cult.
Helped out a friend doing an art class project. They are making an installation with paper tubes hanging from a roof. When you walk into the tubes a loop should start playing. Solved this with an old motion sensor from an alarm system, connected to an Arduino, connected to the PLAY button of a hacked MP3 player. The play button is connected trough an opto coupler just in case. There are some timing concerns to control the MP3-player, like giving the MP3 player time to play the loop all the way trough without new play pulses, therefore the Arduino.
The whole hack took me about three hours and was made mostly out of trash lying around my workshop.
