More High Voltage Experimentation With A Flyback Inverter

March 24, 2011 by 16 Comments

[Electorials] actually makes working with a flyback inverter sound rather easy. This comes hot on the heals of the huge high voltage collection we saw the other day, but slows way down in the presentation of information. This makes the project very approachable for the newbie, especially considering that the majority of the testing is done with low voltages.

He’s using a flyback transform for this project, which can be pulled from an old CRT monitor. Once you have one in hand, all that’s required to figure out how to use it is a voltometer, a 9V battery, a MOSFET (also salvaged in this case), and miscellaneous components. Once he establishes what each external connection does electronically, [Electorials] builds his circuit on a breadboard, then uses it to create plasma in the bulb above as well as to light up a CCFL.

Redbull Sends Marketing Doodad To Hackerspace Using An Open Source Product

Looks like Redbull is harnessing the power of open source hardware to market their product to hackers everywhere. We’d say that it worked because here we are, posting up some free advertising for them. It seems that a rep for the company dropped off a package at a hackerspace in LA called Null Space Labs. It came in what is obviously a laser cut wooden box, a material that tends to make hackers salivate. Inside they found the board you see above. It took a bit of time to look over the hardware was eventually identified as an Uzebox. Sure enough, then plugged in an original NES controller to the controller port on the back of the board and were playing a version of  Pac-man in no time.

Marketing and advertising have their place in our lives which can be annoying and intrusive at times. But we have no problem with it when done creatively and targeted to our interests. Good job Redbull, and might we add, that’s a heck of a routing path for your PCB outline!

Video Experimenter Shield

March 24, 2011 by 15 Comments

People always want to do more with less and the Video Experimenter Shield is no exception. Consisting of an LM1881 video sync separator, a handful of passive components, and a stylish PCB in the standard Arduino shield footprint.

The board features simple but useful controls and features, a removable jumper allows you to select a sync source, either from incoming video or the Arduino, a potentiometer to adjust the analog threshold, and there is a convenient signal breakout header.

Software is an enhanced version of the popular TV out library and allows you to start off with video graphics overlay, closed caption decoding, a simple gun game, and basic, but still effective frame capture, and computer vision. Of course, there are all sorts of other fun and amusing experiments that start to pop in mind once you check out a quick demo video after the break.

Virtual Serial Bridge

March 24, 2011 by 10 Comments

When you are running emulators or virtual machines it may be sometimes handy to be able to connect a serial port from the guest machine to the host machine. [Aurimas] had that issue, and also had a fun fix for that using 2 USB <> Serial adapters, but as you can imagine that is not a ideal solution, enter the Virtual Serial Bridge.

Digging around Vmware it was found that the support for what he needed was there, but not really used. A little addition of a few lines to the guest OS vmx file and configuring the socat multipurpose relay package. Though the instructions revolve around the Mac platform as the host and Windows as the guest socat and Vmware you can probably mix it up with any software that uses the serial port and a *x or windows host.

Portable NES Console Gets It Oh So Right

March 24, 2011 by 16 Comments

nes_portable

[Doug] over at the moddedbybacteria forums has been working hard on a fantastic looking portable NES console and wrote in to let us know it was complete.

The console started as a simple idea to use a Nintendo on a chip (NOAC) board in order to create a portable console that played original NES cartridges. Once a plastic case and some batteries were sourced, along with the NOAC board, the project was well on its way.

[Doug] eventually decided that he would rather use a real Nintendo motherboard in the project, so the NOAC was scrapped…temporarily. He accidentally fried the Nintendo board, so it was back to the NOAC, but with upgraded wiring to take care of some interference problems he was having earlier in the build. An original NES controller was disassembled for use in the console, which gives the portable an authentic feel. Getting the case to look just right was a long process, but we think he did a great job with it.

If you want to take a look at his entire build log, be aware that it is 23 pages long. If you’re impatient and want to jump straight to the unveiling, that happens on page 22.

Keep reading to see a pair of videos [Doug] put together both during the production and after his build was completed.

If you are interested in seeing some other portable NES consoles we have featured in the past, look no further than here, here, and here.

Mini Arcade Cabinet Looks As Good As The Real Thing

[Ed] had a netbook he no longer needed and decided to make it into a mini MAME cabinet for some of his family members. MAME cabinets are pretty plentiful, but this one was so nicely done, we wanted to share it.

He removed the monitor from an EeePC 901 in order to get some precise measurements, then went about crafting a mini cabinet from MDF. The whole thing was wrapped in sticky label paper adorned with old-school Galaga graphics, then covered in plexiglass for a nice sleek look that also protects the artwork.

He used an iPac 2 controller board to wire up all of the buttons and joystick to the netbook, opting to solder the controller’s wires directly to the USB header on the eeePC’s motherboard. A power switch was added up on top for easy operation, and the cabinet was sealed shut, though the back does open easily in the event that maintenance is required. The system is managed using the Maximus Arcade front end for MAME, which [Ed] claims is incredibly easy.

If you are interested in making your own MAME cabinet, check out some of the other MAME-based projects we have featured in the past, and don’t miss the video below of [Ed’s] cabinet in action.
