When my children got these interesting and very obnoxious toy dinosaurs last year, I could barely contain my excitement. I knew that one day, they would be on my work bench giving up their secrets. Cruncher is a fairly recent addition to the robotic animal trend that we’ve been seeing the past few years. Imbued with a personality that is a mixture of T-Rex, beagle, and loudmouth jerk, he’s every kids idea of a perfect pet.
Building a circuit on a bread board makes life much easier, but eventually you’re going to want a PCB for one of your circuits. Luckily, [Will] from Revolt Lab put up a trio of posts that will take you idea and turn it into a schematic and PCB.
First up is an awesome tutorial on the circuit design program Fritzing. While you won’t find Fritzing on the computer of anyone making a living doing circuit design work – those people usually go for Eagle or KiCad – Fritzing is very easy to use but still has a ton of features. Using Fritzing isn’t very hard, either. [Will]’s tutorial goes over copying your breadboarded circuit into Fritzing, creating a schematic from the bread board layout, and finally converting that to PCB artwork.
Once you have board artwork for your circuit, you’re probably going to want a real-life PCB. [Will]’s board etching tutorial goes over the toner transfer method of PCB creation. Basically, print your circuit onto glossy photo paper with a laser printer, put it face down on a copper board, then take a clothes iron to it. If you’re lucky, the laser printer toner will have transferred to the copper making a nice etch resist. To get rid of all that superfluous copper, [Will] used ferric chloride but a Hydrochloric Acid/Hydrogen Peroxide mix will work just as well.
Before you etch your boards, you might want to thing about building an etch tank that keeps all your slightly dangerous chemicals in one container. [Will]’s etch tank uses a large water container and a few pieces of LEGO to suspend the board in the etch solution. It etches boards a lot faster than laying them face down in a tray, allowing you to go from idea to finished piece a lot quicker.
It looks like 2012 is shaping up to be the year of the resin-based 3D printer. The latest comes from [Michael Joyce] and is called the B9Creator. Like other resin printers, [Michael] used a DLP projector to cure the print one layer at a time. The layer height is on the order of 100 microns – crazy for a kit-based printer.
There is a Kickstarter for the B9Creator where kits are available for $2400 USD. Everything is included in this kit, including the DLP projector and a kilogram of resin. $2400 is much more expensive than even the fanciest melted-plastic 3D printer such as a Makerbot or RepRap, but that’s the price you pay for high-quality prints.
Of course this project comes a month after an earlier, similar, and shadier project called the Veloso 3D printer. The B9Creator promises to be open source once all the Kickstarter machines are shipped out, and [Michael] is very open about his designs and his resin formula – an admirable quality in a maker.
You can check out a load of videos of the B9Creater we found after the break.
Florin ordered some PCBs from Iteadstudio, a pcb prototyping service. As part of their service, they claim that all PCBs are tested before they are delivered. However, many have been bringing this claim into question. [Florin] found a complete lack of any markings indicating actual probes had been used on his boards. Though they claim that 100% of the boards are e-tested, they replied to his inquiry somewhat cryptically.
All of the pcb’s have a stripe on the edge,it does not mean they have all been electrically tested ,it is the same as outline .
People on the Dangerous Prototypes Forum have been finding similar results. The company has commented, on this page, that that they will be responding to this soon (back in February)
We’ve seen Arduino-based game controllers before, but the UnoJoy project wants to make it easy for you to plug them into a gaming console.
The project is targeted at the Arduino UNO. Why only that hardware… isn’t Arduino universal? Well yes, but in this case the bootloader needs to be overwritten so that the Arduino will enumerate as an approved controller on your game system. Here the device is being put into DFU mode in preparation for flashing.
Once that part’s done it’s time to get to work on your own hardware interface. The UnoJoy library provides all of the hooks you need to push controller data to the game console, it’s up to you to use the Arduino IDE to decide when these events happen. This would be a great opportunity to make the Pinball Stop controllers work with the Xbox Live Arcade games. Or take a look after the break to see [Alan Chatham] using the library to control Gran Turismo as if it were an NES Power Pad game.
[Scott Lambshed] took some time to shoot a video tour of egMakerSpace’s new digs. This hackerspace is located in East Gippsland Australia, which is to the East from Melbourne. We know the banner image we chose isn’t all that descriptive, but just look at all of that space! They’ve got a bounty of rooms to use for everything from crafts, to machine/wood shop, to retro computing. There’s even a nice outdoor patio area which was a bit overgrown to start with but cleanup has already begun.
The group is just getting moved into what must have been an old hospital or school. Aside from some network infrastructure, a room full of couches, and a few tools, there’s not a lot in place yet. But one thing that is already looking quite good is their horde of electronics components. The latter half of the video shows boxes, bins, trays, and tackle boxes full of goodies just waiting to make it onto the next protoboard project.
[Scott] is hoping to get the word out in the area about egMakerSpace, and that’s exactly what these introductions are for. So grab you favorite video capture device and send us your own local hackerspace tour.
