Got an idea for a cool project to hack on? List them here! (No idea is too simple because it's always version 0.x :D )

 

Ideas:

 

Mp3 Audio Boombox

 

~: mkdir -p Projects/mp3_boombox && cd ~/Projects/mp3_boombox
~/Projects/mp3_boombox: cat title
~/Projects/mp3_boombox: Mp3 Audio Boombox using foam cups
~/Projects/mp3_boombox: cat sypnosis
~/Projects/mp3_boombox: Make DIY mp3 speaker using foam cups. Paint it black and put a HackerspaceSG sticker over it! 
~/Projects/mp3_boombox: cat items_needed
~/Projects/mp3_boombox: * Household stuff for the speaker
~/Projects/mp3_boombox: * Embedded system for the player? (USB-based so anyone can plug and play)
~/Projects/mp3_boombox: cat contributed_by
~/Projects/mp3_boombox: @Kenny Shen

Ultimate Todo Recorder in a Keychain

 

Summary:

A simple todo list recorder where entries can be keyed in via different media.

     eg. Record voice entries straight to keychain.

          Text entries in client browser on PC, laptops, smartphones thru a server app that resides in keychain.

 

Build list:

1 x USB keychain that can blast WIFI and act as local server

1 x Server app that resides in the USB keychain

1 x Mic + voice recorder in USB keychain for voice entries

 

Binary Clock

6 columns of LEDs on the clockface, telling time in binary format.

 

Twitter Ticker

Hang a small LCD display that flash our latest twitter/FB status message. We can also send messages to it thr our IM.

 

HackerspaceSG's own access system

 

Real-time Crowd Sensor (RTCS?)

Motion, IR... Idk yet, but something that can plot the number of people present in the space and send it online to a visualisation so members can see how 'crowded' the space is.

(Thought:  If we implement the bluetooth access system mentioned in the project above, it also would provide a rough idea of number of people (those who have BT enabled.  It also could indicate number of people present who are not members (again if they have BT enabled but not paired).)

 

cat << RTCS-PROTO

IR == Too simple; we don't just want numbers; not fun enough =p

RTCS-PROTO

 

Pub conference system

A system to get around the problem of loud pubs and let the people be able to talk to each other. Headsets w mic and everyone can be assigned to some key so u can turn off and on his/her mic...

 

Books for needy libraries

One of the problems facing libraries, especially those in rural areas is that they do not have access to the latest available books. Cory Doctorow recently released his latest work (Makers) as a FREE eBook download and hardcover edition simultaneously. Doctorow also set up an informal, manual system whereby 1) Needy libraries could request a copy of the book and 2) Those who read the eBook edition for free was requested to purchase a copy for one of the listed libraries.

This project wants to extend this idea to allow fractional donations/purchases toward a book, so that e.g. 5 people pitch in as their finances allow to collectively purchase one book for a needy library.  - by Stephan M. February

 

Resurrect HuddleChat

A while back a couple of Google engineers engaged in a side project to demonstrate Google AppEngine. The project was called HuddleChat, and was essentially a Campfire (http://campfirenow.com/) clone. 37Signals cried foul, and for some unknown reason the project was taken down. Campfire does not have an API, and 37Signals has no plans to provide one. I'm being forced to use Campfire at work, and it's getting unbearable. This project will resurrect HuddleChat ( I've registered huddlechat.net) and slap a RESTful API on it.  - by Stephan M. February

 

Singapore Robotics Games 2010 - Pole Balancing Robot

RP is hosting robotics games again in 2010.  I was looking through the competitions and thinking that the pole-balancing robot might be something we could do quickly and have a reasonable chance of success.  The competition is on 26-28 January, so there is not a lot of time.  Here's the description/rules--or at least the rules from some time ago.  They look similar to those I have that are more current, but there does not seem to be much of a website for this competition:  http://guppy.mpe.nus.edu.sg/srg/srg98/pbr.html

 

 

The Fun Theory

 

Water Rocket

Something fun. Build our own water rocket!

 

Ha(ck)m Radio

Our own amateur radio operation.

This is too simple.

How about getting IDA to work with us to do research on GSM900/1800/EDGE networks by getting a spectrum from starhub or singtel for example? We can use an opensource Basestation Transceiver running linux and an omnidirectional antenna tied to a tree with ISDN PRI connection for data access for the phones.

There are others which we can work on - VoIP,P2P multimedia streaming to even the most hardcore - high performance computing.

Why don't you do it then? We are not a group of people to do something with a common goal. If you have an idea, and you wish to do whatever you just described, feel free to use our space when it's ready to hack out your own research. Feel free to edit the page and put it in the ideas list.

Justin Lee said

PS.
And maybe other people might also be interested to do it. If you have an idea, you should just try it out! That's the purpose of hackerspace. Maybe someone else would also be interested to join in and help out.

Hey Nuzaihan you've got good ideas. Help us list them out on this page? Having more interesting project prospects would certainly attract more hackers, funders & visitors :)

There are many. on networking side, native IPv6 LAN (with IPv4 of course) if we have hackerspace hangout, tunneled over IPv4 on the router end to a broker in HK or MY, with global unicast addresses for IPv6 (you can host servers reachable for IPv6 from internet within the LAN - which is firewalled on gateway to allow some ports). Other things which is not really important but if you wish to know is Appletalk filesharing, IPX/SPX if any of you guys did the old school networking in the past.

AAA - Kerberos (which is modified and implemented on ActiveDirectory) with Single-Sign On to servers. 802.1X on wired and wireless networks.. radius.. etc....

Wireless...... WPA especially.

Hardware side would be extended RFID skimmers, retrocomputers, specialised DC-powered computers (for green energy), low-powered embedded computers (ARM32, IBM Cell (PS3)) and more, robotics (LEGO NXT or homebrew $50 robots that use motors instead of servos... )

Telephony as above.. GSM/WCDMA technologies... telephony using VoIP which is not new but still, unlike the proprietary P2P skype, many providers still use SIP ... things like eavesdropping via MITM.. etc..

Software side, GPGPU technology using OpenCL programming.. or our own private bittorrent tracker.. android or iphone app coding...the possibilities are endless since most of the technologies are opensource, are available.

These are what i can think of now. There are many i would like to include but seemed to be mediocre (like flash servers streaming and such but we can use this technology to stream live broadcasts) or even this: http://www.defconbathroomcam.com/ (just kidding) :)
But this depends on the your budget... especially on hardware.

Still i do not wish to intervene the admins who started this initiative, i'll let them decide on what's good and what's not. ;)

@Muhammad Nuzaihan, please feel free to add and update anything you wish. We are creating a hackerspace for people like yourself. We're working hard for you, and for us too in order to achieve this dream of ours. But it is people like yourself who make what hackerspace is. Do not worry about intervening. There's no such thing as admins or whatever here. Hardware-wise, it will depend on individuals who want to bring in these hardware to play. If we have any left over money, we'll gladly bring in some toys for people to play with. I don't think we'll have the money or resources to bring anything additional.

Anyway, you can help by contributing all this ideas into the wiki, and anything you wish to help out with. We're looking and thinking of all possible ways to try and make this hackerspace a reality, and keep it sustainable.

Yeah. Instead of placing ideas into this comment thread, which is not what it's meant to be, why not add it straight into the wiki? :)

A warning: Don't use keyboard shortcuts for formatting; messes up pre-formatted tags sometimes and you'd have to edit in source view to remove them.

Nices projects going on there. The problem with some hackers is that the things they do are not always legal, in the sense that if they write out what projects they are currently tweaking in, they would get sued, and probably end up in jail. So that sometimes contradict the thing about hackers and public sites. Well, the more legal things that I wanna do is a budget thermal scanner, like something less than $1k. These would have to be assembled from cheapo items you can readily buy from DIY shops. You know those commercial thermal scanners available currently in the market usually costs upwards of $10k. Me being me, I also wish to create special LCD screen lids for laptops that glow on the outside lid with customized shapes, something like Alienware laptop but I hate the stupid Alien head, and prefer to have my customizable glowing shapes instead. I mean it's easy to do for one laptop, but what is commercially feasible is a on-the-spot choose your preference and viola. Of course that definitely excludes the work about having to add in the wiring. For the shapes, might be possible to use 3D printers and then put the lightning behind and connect the wiring to the motherboard. Might be only available for selected models. So many projects, so little time.

Hi Eric! Turns out that making an infrared camera from just about any digital camera or webcam is as easy as pie! http://www.hoagieshouse.com/IR/ has a nice summary. Digital camera ccd's are actually better infrared cameras than they are visible light cameras so this is a really easy hack.

Hi John, thanks for the response, you made me happy for 5 seconds. The link you gave is about IR camera and not the thermal scanner that I am looking for. The thermal scanner is those you see at the airport when people walk past, you can see their body heat and can tell right away if someone is having a heavy fever?
