XT IDE controller

[Geordy] wanted to use some IDE devices but he didn’t have an interface card for his XT system, which can’t handle 16-bit  IDE. He looked around for 8-bit ISA controllers but they were hard to find and quite expensive. Lucky for him there’s an open source project that makes a solution to this problem. The XTIDE project brought together a … Read the rest

DIY picture frame better than store bought

[Daniel's] homemade digital picture frame looks great, it’s well-built, and it has a nice set of features. It’s not made from a broken laptop and he didn’t build it around a microcontroller. Instead, he saved a 19″ LCD monitor with a burnt out back light caused by the extremely common blown capacitor problem. Twenty dollars on eBay landed … Read the rest
