Rose

A rose engagement ring. Coming up with a design for this piece was quite tricky. I wanted to make something with strong rose influence without being too cheesy. The ring needed to be light and elegant on a fairly small finger, but durable enough to last a lifetime. I came up with some initial sketches, discussed them with the client


 

and we landed on this one, but without the leaves. 

After an long, winding journey through metal casting, I ended up with this piece. I'm very pleased with it.

Fountain Pen Repair

Faye has a nice Shaeffer White Dot fountain pen, and brought it to me with a problem. The gold nib is screwed onto the plastic section assembly ("section" is the name for the part of a fountain pen between the nib and the barrel; the bit one holds when writing) with a few fine threads which had stripped.

Being and speaking at 25C3

You know that weird period between Christmas and New Years, when nothing really gets done? This year, I spent mine at 25C3; the 25th annual Chaos Communication Congress. Four thousand-odd geeks from around the world gather to share their ideas, hack, talk, game, build, start collaborations, and more. I'd never been to a hacker conference before, so I decided to jump in at the deep end and give a talk on Formica! It was a truly incredible experience...

Sapphire Cocktail Ring

I made this sapphire ring as a Christmas present for Faye. It's minimalism is unusual for a cocktail ring, but I think its impracticality puts it squarely in that category!

Plasma TV Brackets

Justyn bought an amazing plasma TV on ebay for a bargain £50. It was sold as broken, but it seems the seller was incapable of pressing buttons - it actualy works fine. It lacked a stand or any means of attaching it to a wall. For a few weeks it was simply gaffer taped to the radiator, but eventually we could live in fear no longer, and decided to fabricate some brackets.

The back of the TV has some captive nuts to screw a bracket to. Justyn bought two 500mm lengths of 20x20x3 steel box from Metal Supermarkets, and I supplied the metalworking equipment.

3rd Year Project

Thought I'd make my 3rd year project writeup available. It is a switch-mode power supply with digital PID control implemented in a low power microcontroller. The aim is to achieve a higher performance, more flexible design than a traditional analogue supply without the high power consumption of a high-speed DSP.

It scored highly, so might be worth reading if you're a 3rd year Electronic at Southampton.

Emerald Pendant

It was about time I made a piece of jewellery for my good friend Lou. She likes green, and I like precision handiwork, so I thought this pendant would make a nice birthday present. It features a 6x4mm oval emerald tension set in the central cutout, and two 1.5mm diamonds bead set at the top and bottom.

PSP Wifi Reflow

I reattach the wifi module to a PCB from a Playstation Portable using my hot air reflow station.

Internal Bluetooth

I wanted to add internal bluetooth to my tablet PC, so I took a USB bluetooth dongle and shoehorned it into my tablet; adding a little control PCB to allow it to be turned on and off.

Blue Paua Cufflinks

My second stone setting project (well, shell I suppose) was a pair of silver cufflinks bezel set with Blue Paua shell from New Zealand. It's also known as Blue Abalone.
