Build a Microwave Transformer Homemade Stick/Arc Welder
stasterisk

I had no idea making a DIY welder would be so easy to do. And, it's pretty muchFREE!
Additionally, the stick welder you get is definitely better than anycheap commercial welder you can buy.
Why is this homemade thing better than something you can buy? Because when you factor in shipping and labor and the little bit of retail markup - the companies that make typical cheap buzz boxes will skimp on copper as much as possible. Whereas you can use enough copper in this to make something really juicy, and still spend less, to nothing, compared to a store-bought arc welder.
So here's what you need to build a welder:
- Two beat up old microwaves
- Some 10 gauge wire
- Wire nuts
People throw out microwaves all the time, if you keep your eyes on the curbs.
Or, you can get microwaves at the local thrift store for $10 each.
Try the warehouse that processes donations - they have to pay to get rid of tons of broken ones.

Agora, se quizerem maquinar Placas MESMO grandes, atenção, malta das Pranchas de Surf, para Moldes, têem esta maquineta que vai maquinando a placa, andando nela!

Boa ideia, que vos poupa uma fortuna, e ainda vos poupa espaço na Oficina.

Review: Printrbot Crawlbot Changes Everything About Large CNC Routing

Jason Loik

Printrbot just released the Crawlbot, a game changer in the world of CNC. It takes one basic fundamental of CNC machines and throws it out the window: The idea that if you want to cut a large piece of material, then your machine needs to have an even larger frame. Instead, the Crawlbot is the size of a golf bag but can cut material larger than a sheet of plywood.
This is the perfect machine for the at-home tinkerer, someone who doesn’t have a lot of work space but can back the car out of the garage on the weekends. If you want to cut full sheets of plywood, you no longer need to put an unmovable, VW-sized machine in your shop, taking up a substantial amount of room. Instead, you store the Crawlbot in a tight space, then when needed you simply strap it to a single piece of plywood on a few sawhorses and let it run. And it costs $4000 (currently set at an introductory $3500), where traditional machines with comparable capabilities start in the tens of thousands of dollars.

Formlabs’ Brand New 3D Printer, the Form 2
Formlabs has been listening, and their latest 3D printer brings home much-wanted features
Matt Shultz

With the release of the Form 2, Formlabs has taken all they have learned and released a machine that is set to keep them on top.
Today, Formlabs announced Form 2, a larger machine with a bigger build volume and new technical innovations. It’s not just an iteration, but a reimagining of the printer that brought stereolithography (SLA) printing to the desktop. It’s priced at $3499 and, unlike their initial release, will not be Kickstarted.
Make: magazine was invited to Formlabs’ headquarters earlier this month to test out a beta version of the Form 2; this is our full review of the brand new device from the upcoming Ultimate Guide to Desktop Manufacturing in our November issue of Make:.
