Computer based Music Library
Have posted about this project elsewhere on this website, but now that I have a few photos it seems that this forum is a more appropriate place to post updates on.
Basically, I am converting an old PC into a music jukebox of sorts and modifying it to suit the purpose. The woodwork side of this project has been the construction of a Solid English Elm case to cover the computer incorporating a small LCD screen for a monitor on the front panel, as well as a variety of control inputs including a scroll wheel selector knob (a project in itself involving parts sourced from a model helicopter, an old vcr, tap washer, to name a few!).
Currently, the case is sanded and waiting to be lacquered.
Will put up more photos as final assembly progresses.;

I really like the look of this!
A few questions:
a) the cutting of the angles - how did you do this and get it so right?
b) have you made up jigs for cutting the CD slot, holes, etc? I noticed nicely routered out rebates inside...
c) the electronics photo - is this a rotary encoder?
Anyway - keep us posted and inspried!

a) There is a bit more info about the method I used to work out the angles with Google Sketchup and how I cut them in my original thread here: http://www.woodworkforums.com/f11/go...elcome-114206/
b) The routing was mostly done using a copy router at work (similar to this one: http://img.diytrade.com/cdimg/105437...chnologies.jpg) that is really designed for use with aluminium, but does well with wood as long as you only go about 5mm deep on each pass. Basically it clamps the work piece to the base and you can set the limits for the router bit with stops, which you then pull down to meet the workpiece with a handle and move it within the preset stops to cut out the desired shape.
c) The electronics picture is indeed a rotary encoder, used to browse and select songs to play. It is based on an old computer mouse to which I have added a circuit that emulates a double click (to start playing a song) from a single press of the dial. It also has a function to pull on the knob and twist left or right to quickly skim through the list of albums on the screen by activating page up or page down keys.
I have just had some icons/symbols cut from silver sign writing vinyl that I will stick on the front panel and remote beside the buttons between coats of lacquer that should hopefully be sprayed on by a neighbouring business at work sometime early this coming week.

Well, you've got me hooked so you had better keep the photos coming of your progress!
You've got me planning my own hifi now...

Just got the lacquering finished today and have brought all the pieces back home to install the electronics into. Tonight I managed to get the remote control together and tested OK. Here's a few photos:

Nice work - I've been wondering how to make wooden buttons for remotes and other electronic appliances that have micro-switches. From memory, most remotes have a rubber mat above a contact switch PCB... how do you secure the buttons so
a) they don't fall out, and
b) work reliably
Nice job - keep it coming!

Thanks. The switches I used were these ones:
SP Momentary Push "On" Push Button Switch - Single Black
As you can probably just make out in the picture there are little clips each side that hold the black plastic buttons on. I simply unclipped them, laid them on their side and used a sharp chisel to slice off the top cube of the button and replaced it using epoxy glue with a small cube of wood, then clipped them back on to the switch body. Pretty fiddly but do-able.

Got the left hand knob completed last night. Rather a lot of effort (and considerable tweaking to get smooth operation) to get the simple functionality of twist left (previous track), twist right (next track), and push (play/pause). But quite an enjoyable little project within the larger project all the same.
A few pics of my workspace in action, and ever handy collection of miniature screws I have accumulated over my lifetime. Something about the colorfulness of the tools and materials in this sort of hobby appeals to me visually.

Are the electronics your own design or are you working from a kit? You'll be very pleased when it all comes to life!
You've got me going on my own HiFi project now - it'll be a tube amp though, a kind of woodpunk thing. Parts are ordered and in transit...

I just came across this thread - you've done a fantastic job there Johnnz
That is one incredibly funky cabinet !!
I've just built a HTPC myself using left over bits of old computers, but didn't even think of putting it into a timber case like yours. Looking forward to seeing the completed project in all its glory.

The only electronics I had to make was the double click emulator which I was helped with on an electronics forum website. The rest is mainly just the connection of switches hardwired into the control circuitboard inside the computer keyboard.

Sorry, wasn't paying attention....
I run the 32-bit Windows 7 MC on my box, with a Logitech remote programmed to do just about anything. Fairly easy navigation for watching live TV, recording TV, playing music, viewing photos, watching DVDs and so on.
The only hassle is the EPG, but I'm exploring a few options for improving on that.
If you choose the right components, you can make up a media centre PC that runs very cool indeed and will fit into a tiny case.

In case you haven't found it, this online forum is a great resource for HTPC builders:

Not quite such a frantic place as this forum, but there are many knowledgeable folks there that can help with any HTPC issues you may have.
