Fresh hacks every day
Okay, we think it’s questionable when people say they have no problem soldering QFN packages, but BGA? Granted this chip has far fewer balls on it than many, but it’s still quite impressive that [Xevel] was able to solder this BGA breakout by hand.
The chip you see above is a TMP006 infrared temperature sensor from TI. [Xevel] picked … Read the rest
This DC-DC Bipolar PSU was developed for use with a guitar effects pedal. [Obsolete Technology] needed to source both positive and negative 15V. This is pretty easy to do if you’re converting from mains, but he wanted a solution that could work with a lower-voltage AC/DC wall wort or even from batteries.
The part that pulls it all together is … Read the rest
The rig pictured above works as an Internet connected temperature sensor which sends [Zaion] an email with a graph of the change over time. This in itself is interesting, but one part in particular caught our eye. He’s using an i2c temperature sensor , and we think the PCA9517 Level-Translating I2C Bus Repeater that makes it possible is a perfect … Read the rest
When [Steve] saw that we requested reader’s solutions to storing hundreds of different components, he had to send in his solution to storing bunches of ICs, resistors, transistors, and other components.
Like most of the suggestions we’ve seen, [Steve]‘s solution relies on #10 envelopes stored in boxes specifically designed for holding envelopes. While there’s nothing new about storing handfuls of … Read the rest
On a business trip, [ch00ftech] visited a Shenzhen electronics market and documented the trip. Some of the attractions included multiple Apple stores of questionable authenticity, stores selling PC components with no manuals, drivers, or packaging, and a variety of LEDs and lasers.
[ch00ftech] showed off the loot from the trip, including breadboards, perf boards, LED matrices, and an RFID reader … Read the rest
[Ben] wanted a switch mode power supply for his breadboard. He ordered a PTH08080 module which is made by Texas Instruments. The spec sheet would make it a great choice for him, but he was not happy to learn that the pinout doesn’t conform to the 0.1″ spacing used by solderless breadboards. His solution was to make a breakout … Read the rest
Earlier this summer, I took a trip through the southeast of the country. On this trip I was able to visit several hackerspaces and meet some really great people. We started at Squidfoo in Springfield Missouri. Then Moved on to Makers Local 256 in Huntsville Alabama. After that we saw 7hills hackerspace in Rome Georgia as well as Freeside hackerspace … Read the rest
