Consumer HMD comparison


We’ve wanted headed mounted display technology to take hold for a long time. Gizmodo recently compared two consumer models: the Zeiss Cinemizer ($400) and the Myvu Crystal ($300). Unfortunately the resolution of HMDs has gone nowhere in the last 10 years. These two devices only support 640×480 and are aimed specifically at iPod users. With computers getting smaller and higher resolution, we’re surprised that HMDs have not followed suit. Why isn’t someone going to market with a 1280×720 headset? If you really must choose one of these two, we’d recommend the Myvu. It has composite input so you can hook almost anything up to it.

DNS spoofing with Ettercap


[IronGeek] has published his latest video how-to: DNS Spoofing with Ettercap. Ettercap is designed specifically to perform man in the middle attacks on your local network. It can do ARP poisoning, collect passwords, fingerprint OSes, and content filtering. For DNS spoofing, you just need to edit a config file that defines which domains resolve to which IP addresses. You can use wildcards for the domains. In the video, he uses Linux because the network interfaces are easier to remember. Once you’re done playing with DNS spoofing, remember to flush your local cache otherwise your browser will continue to go to the wrong IP.

More hardware music


today and tomorrow found a few more projects using computer hardware to create music like our earlier Radiohead post. Above is a rendition of The Imperial March using a 3.5 inch floppy drive. Two more projects are embedded below.

IR controlled relays


If you’re thinking of building some DIY home automation, this looks like an interesting idea. At the heart is a PIC16F84 that decodes IR signals and controls six outputs – in this case, relays to activate various appliances. The PIC is dirt cheap – if you get a deal on some relays you should be able to build a small local IR HA system for $30… This might be just the thing for my office. It’s cheap enough that it probably wouldn’t walk off.
