Fresh hacks every day
One of [Sprite_tm]'s colleagues recently challenged him to connect a small LCD touch screen to a Raspberry Pi. Sadly, [Sprite_tm] has yet to take delivery of a Raspberry Pi, but he did manage to connect an LCD to a Linux board without video capabilities. Because [Sprite_tm]'s display has a 16-bit parallel interface, and 16 GPIO pins are hard to come by on the Carambola Linux board, a few … [Read more...]
When the Regency TR-1 transistor radio came out onto the market in the 1950s, it was hailed as a modern marvel of microelectronics. With only four transistors and a handful of other components, the TR-1 was a wonder of modern engineering. [Sprite_tm] may have those old-timers beat, though. He built an FM transmitter with the lowest parts count of any transmitter ever. Like most of … [Read more...]
[Sprite_TM] is was sent an old LED Marquee by an anonymous fan of his hacking projects. The display isn't full color, but it's large -- 224 by 48 pixels -- and he figured he could render some okay images with the bi-color diodes. In the end, he replaced the controller and turned it into a video player. The original system work well enough, but the 100 MHz 486 industrial style PC that drove the … [Read more...]
It's been a while since we've seen [Sprite_tm] pull a project from thin air, and we haven't seen him do anything with a Raspberry Pi yet. All things must pass, and finally [Sprite] has unleashed his tiny, pocket-sized MAME machine to the world. The build uses a Raspi for all the Linux-ey and MAME goodness, but [Sprite_tm] didn't want to fiddle around with the HDMI or analog video output. … [Read more...]
NAND flash, the same memory chips found in everything from USB thumb drives to very expensive solid state disk drives, are increasingly common. As they (partially) serve as the storage for cellphones, Wiis, routers and just about every piece of consumer electronic devices, you're probably surrounded by dozens of NAND chips at any one time. [Sprite_tm], hacker extraordinaire, put up a build a … [Read more...]
We see LEDs used in all kinds of projects but rarely does someone build a home lighting system from scratch with them. [Paulo Oliveira] decided to give the idea a try, included a fading power supply for the LEDs which he built himself. Here you can see the installation at full brightness, but his controller also offers a single lower setting. We saw [Sprite_TM] use an RGB LED strip to light up … [Read more...]
[H. Smeitink] got his hands on a 320x240 color TFT LCD screen. He set out to drive it with a small PIC microcontroller but didn't find a lot of help out there to get up and running quickly. This is surprising since it's a really nice display for quite a low price (under $16 delivered on eBay at the time of writing). He decided to write his own library and support tools to help others. The … [Read more...]
