Fresh hacks every day
In modern computer systems, the biggest bottleneck of information tends to be in communicating with the hard disks. High seek times and relatively slow transmission rates when compared to RAM speeds can add up quickly. This was a necessary evil back when RAM space and costs were at a premium, but now it is not uncommon to see 4GB of … Read the rest
Those who are familiar with Atmel’s line of 8-bit AVR microcontrollers should already know that some of them have support for external RAM. But have you ever actually used this feature? We haven’t. Now you can learn how it’s done by reading through this guide. It touches on all of the hardware, but doesn’t dwell on it. Instead, you’ll … Read the rest
iFixit traveled all the way to Japan to bring you this iPhone 4 teardown, only to be shipped the device unexpectedly two days early!
We were surprised that the A4 processor (its naked body displayed for the world this past April) contained within the iPhone 4 had 512MB of ram, compared to the 256MB of the iPad. Other … Read the rest
[Stephanie] beefed up the hardware on her Dingoo A320. She enjoyed the features that the A320 handheld gaming system offered, but wanted the 64mb of RAM available in its bigger brother, the A330. A comparison of the two led her to believe a swap might be possible and after sourcing a pair of replacement chips for $12.50 she took … Read the rest
Want 21 megabytes more ram in your Nexus One? [Coolbho3000] worked out a way to tweak the kernel and remap memory usage to free up some resources. That means this comes as a custom kernel image requiring no hardware alteration. Try it out and share your experiences in the comments. But if you don’t need more ram you can … Read the rest
Sometimes your project needs a lot of non-volatile ROM, right on cue [Matthew] let us know how to not only connect, interface, read, and write to SD cards with a PIC over serial, but also how to do the above mentioned with an old PATA HDD. For those without a PIC/serial connection don’t fret, [nada] let us know about … Read the rest
[Pelaca] upgraded the RAM on his D-Link DIR-320 router from 32MB to 64MB. This hack is simple enough: swap out the existing RAM chip for another one and change the bios to make use of the upgrade. The actual execution is not that simple because of the pitch of the TSOP II package; you’ll need to bring your mad soldering … Read the rest
