Fresh hacks every day
When [Michelle] was making a sign language translation glove, she needed a bunch of flex sensors. These flex sensors cost about $10 a pop, meaning her budget for the project was eaten up by these bendy potentiometers. Since then, [Michelle] figured out a great way to make extremely inexpensive bend sensors using anti-static bags and masking tape, allowing her to … Read the rest
Over the last year, [James] has been a part of a few commercial projects that used a thermal receipt printer as part of the build. Something must have cracked in his mind, because [James] spent a lot of time developing a way to print customized content on receipt printers, connecting these printers to the Internet, and sharing content with other … Read the rest
Your experience with making things, building projects, and hacking hardware is directly proportional to the amount of components you have on hand; as our experience grows, so do our space and storage requirements, it seems. [Danh Trinh] must have decades of experience, because his StorageBot robotic parts drawer is as awesomely absurd as it is clever and useful.
At first … Read the rest
LCD displays taken from old Nokia phones have been a staple of the hardware makers for years now, so we’re very happy to see [Andy] reverse engineering a full color QVGA display so we can move our grayscale projects over to a full-color display.
The screen in a Nokia 2730, 5000, and 7100 cell phone is a wonder of technology … Read the rest
Here’s a nifty programmer for a cheap Bluetooth module. So just how cheap is this part? Does $6.60 sound like an extreme deal?
The information on this hack is spread throughout a series of posts. The link above goes to the completed programmer (kind of a look back on the hack). But you might start with this … Read the rest
Temperature and humidity measurements are a nice addition to many hobby projects. But [Rajendra Bhatt] makes the point that many of these sensors have a price tag that is well above what most hobbiests are willing to spend. He decided to take an in-depth look at the DHT11 sensor; which you can get your hands on for under $3 … Read the rest
ElecFreaks is selling a new color sensing module based on the TSC230 sensor. They’ve posted a demonstration using an Arduino that shows off what this sensor is capable of. The module includes four white LEDs which give a baseline of light to help normalize readings when reflected off of differently colored surfaces. The white balance of the sensor needs … Read the rest
