Featured in a www.diyphotography.net/readers-projects-the-cd-spindle-ri…, it’s a great site for learning, I really recommend!
If you like this and make an improved version, please let me know so I can get some new ideas!
Thanks Kidneri for the idea on using a CD spindle case for the ring, and many other people on Flickr who did a similar project and posted the instructions.
With this piece of cardboard, plastic, tape and glue, I can take 1:1 photos from 30cm of the subject at 1/200s, f/22, ISO 100 in complete darkness, pretty good!
It makes a wrap around light with a soft shadow, much better than any diffuser I’ve tried for macro. Take a look at the photos I’ve taken with this ringflash.
Well, it’s not perfect… there’s a light loss, so the flash may fire at high power and I will need to wait it to recharge, but not much. It’s also too small for portraits, only indicated for macro.

Se você gostar dessa gambiarra e fizer algo melhor, por favor me avise assim posso pegar algumas novas idéias!
Obrigado Kidneri pela idéia de usar um tubo de mídias de CD para o anel, e muitas outras pessoas no Flickr que fizeram um projeto semelhante e colocaram instruções.
Com papelão, plástico, fita e cola, eu consigo tirar fotos 1:1 à 30cm do alvo em 1/200s, f/22, ISO 100 em completa escuridão, muito bom!
Ele cria uma luz em volta do objeto com uma sombra suave, muito melhor que qualquer difusor que tentei para macro. Veja as fotos que tirei com esse ringflash.
Bom, não é perfeito… há uma perda de luz, então o flash pode disparar em alta potência e demorar um pouco para recarregar, mas não muito. Também é pequeno demais para retratos, só indicado para macro mesmo.

£1.50 ($3) DIY Ring Flash! (Weight: 230 grams!!) by Alex [ www.bytefish.com ] on Flickr.Via Flickr:
OK, my ring flash is finished (apart from the cover) and it works! It cost £1.50 to make here in England, $3 to you guys in the states.
Made from:
1x Plastic frosted plate (20p)
1x Recycled Cardboard Hanging Basket liner (80p)
1x Black Graphite/Plastic Plant Pot(50p)
1x Sheet of Tin Foil
1x Bit of Cereal Box Card
1). I used a jigsaw to roughly cup the centre out of the plate, then used a circle cutter to drill the perfect circle out of my plant pot. 
2). I then cut the bottom out of the cardboard hanging basket liner with a stanley knive and some sandpaper to even to circle out.
3). I used silicone sealant to fix the plate around the lip of the plant pot, this fit nice and snug, you could use some superglue or similar adhesive, because once all the parts are together the plate is pressed up against the lip by pressure anyway, so this is just to make the design more rugged.
4). I then lined the basket and plant pot with tin foil, stuck down with PVA glue I found in the shed.
5). Once dry I pressed the plant pot/plate  into the card hanging basket and adjusted the size of the hanging basket hole into the hole thing fit together snug. I then glued the all in place with some extremely heavy duty glue called ‘Mitre Bond’ it is a glue and a fixing spray which hardens the glue in seconds. I used it to glue the black pot to the back of the card basket, and then once that was set (in about 3 seconds!) I sealed the frosted plate to the front of the card basket, all the way around.
6). after the glue had set I silicon sealed the front of the ringflash that I had just glued, in order to protect the inner edge and to tidy up on top of the glue.
7). While this dried I made an adapter the slot into the back of the ring flash and over the on board flash of my Nikon D200. I made this out of cereal box card, lined the inside with tin foil to reflect the light and wrapped it in black electrical tape. I cut a small letterbox shape into the back of the ring flash and secured the adapter in place with the crazy powerful ‘Mitre Bond’ glue. (Note: I added a flap of foil on the end of the adapter that went inside the flash so that it directed the flash light around the ring rather than straight out of the diffusing plate)
8). That’s it! The final weight of the ring flash i approximately 230 grams. In England thats the same weight as a £1.39 bar of Cadburys dairy milk!!
It’s extremely light and extremely well fitting, it hugs around you lenses Nikon mount, especially a Tamron 17-50mm as seen above. It wedges in so well that it doesn’t move at all and it’s so close to the camera’s centre that you can’t feel any weight from the ring flash at all. 
The final item is super solid and ridiculously light!
This works well at close range, fantastic for macro and close up work, and turns your on board flash into a usable light when coupled with your expensive SB’s rather than just being a wireless trigger as mine had previously become.
I hope you like it and maybe this design will help some of you create your own cheap ring flashes. All these parts were bought from ASDA in England, they sell these bits in ALL the ASDA’s across the country.
Hope you like it, please check out the final result here:
