HECO victa 200 repair

victa-200rosewood_1

That having said, some time ago I came into the possession of two simple bookshelf speaker cabinets by HECO, the Victa 200. Unfortunately one mysterious destructive force in my house took the life of one of the tweeters. (this mysterious destructive force has of course nothing to do whatsoever with a button-crazy two year old which happens to live in the same house). Anyway..

I couldn’t find an address selling spares, the original speaker cabinets were quite cheap, but only sold in pairs. The only solution: find some tweeter that roughly matches size and specs of the previous one, and do a replacement.

Being somewhat limited in suppliers, I bought a monacor DT75/8 which has the same cone diameter as the original HECO (only power specs and magnet size are very different)

I used a lot of hot-melt glue, jigsaw and file to make the cabinet useable again. Although the process looks bad and ugly, the sound is much better (compared with no tweeter at all) and even optically you can hardly tell the difference…

MakerBot Thing-O-Matic

without comments

Ok, one could argue that it is cheeting, but before the PrinterPrinter is ready, I thought of taking a shortcut by building a makerbot first. The Thing-O-Matic works right out of the box (and about 200 m3×16 socket screws later):

Recycled plastic bag wallet

with one comment

Use an old iron, set at maximum temperature. Use bake sheets, fold a lot of old plastic bags in between, press hard with the iron.. The idea was also presented at fab6. Now the plastic sheet has been used on a normal sewing machine to make a small wallet. Next up: the big obligatory messenger bag with laptop pouch…

Babbookshelf

without comments

Having recently bought a Babboe cargo bike, my workshop was littered with big cardboard boxes. What to do.. what to do.. A quick look around on the net yielded this designer of cardboard bookshelves. One hour later the babookshelf (babboekenkast) was a fact…

The shelves have been made out of double cardboard, stuffed with rolled strips:

Spool-knitted cable sleeve

without comments

In the category ‘Utterly useless customizations’ the spool-knitted cable sleeve for mac adapter. Why? - the only answer that makes some sense is probably ‘why not’. Besides that, wiring used to have cotton or nylon sleeves with a similar woven pattern, you just don’t get that type of cable anymore these days.. so you could call it retrointerfacing.

Black Cat

without comments

Another nice weekend project: a stuffed cat. Using a pattern from this link I made a nice black cat. It has the same silly look in its eyes that young kittens sometimes have :) It is a very nice A4-design. Just print out, cut fabric, stitch everything together and stuff it…

Cradle

without comments

Another nice DIY weekend project. A baby-cradle that can be fixed to the side of a bed, so both mattresses are flush.
