Fresh hacks every day
It’s totally excellent when a simple concept results in something inspiring and fun. [Rich Decibel]‘s Kequencer is a good example, starting off as many projects do: “I had an idea the other day and I couldn’t decide if it was good or not so I just built it to find out.” Be still our hackable hearts!
[Rich] built this … Read the rest
We’ve all known the MSP430s under the Launchpad are designed to be low power, but who wants to bet how long the chip can last on only 20F worth of capacitors? A couple of hours? A day at max? [Kenneth Finnegan] setup a MSP430 with supercaps to find out. To make sure the chip is actually running, [Kenneth] programmed it … Read the rest
[James] is interested in reverse engineering some integrated circuits. One of the biggest hurdles in this process has always been just getting to the guts of the chip. He used acetone to dissolve the plastic case but had trouble getting through the epoxy blob. Commonly, the epoxy is soaked in nitric acid for a few minutes but [James] didn’t … Read the rest
Quick: which pins are used for I2C on an ATmega168 microcontroller?
If you’re a true alpha geek you probably already know the answer. For the rest of us, ChipDB is the greatest thing since the resistor color code cheat sheet. It’s an online database of component pinouts: common Atmel microcontrollers, the peripheral ICs sold by SparkFun, and most … Read the rest
According to the an article in the INQUIRER, it is very possible that all chips with the G84 and G86 architecture are faulty. The problem is said to be excessive heat cycling and when NVIDIA was questioned, they blamed their suppliers for the issue. Although NVIDIA is claiming that only a few chips that went to HP were affected, … Read the rest
