Install Driver for Trust Flat Scan USB 19200 Flatbed Scanner on Ubuntu/Debian

Portable USB scanners are very useful. They’re lightweight, easy to use, they can run off the power of the USB port, and most times they work right out of the box on Linux. Most times. It’s not the case of the Trust Flat Scan USB 19200 flatbed scanner. Continue reading “Install Driver for Trust Flat Scan USB 19200 Flatbed Scanner on Ubuntu/Debian”

Use an APDS-9930 Ambient Light and Proximity Sensor with Python (Raspberry PI/PC)

APDS-9930 I2C sensor connected to VGA

A few weeks ago I posted an article on how to find your computer’s hidden I2C port. Today I’m going to take it one step further and show you how to actually use it.

After making the Arduino library for the APDS-9930 ambient light and proximity sensor, I decided to port it to Python. In this post I’m going to show you how to use it. Continue reading “Use an APDS-9930 Ambient Light and Proximity Sensor with Python (Raspberry PI/PC)”

Find Your Computer’s Hidden I²C Port and Use It!

If you don’t know what I2C (read “I-squared-C”) is, you may want to check out its Wikipedia page, but in a few words, it’s an amazing protocol that allows communication between one (or more, according to Wikipedia) master devices and one or more slave device, using only 4 wires, two for power supply and two for data. Every slave device has its own unique address that the master can address to request information from the slave.

There are sooo many applications and useful electronic gadgets that use this protocol, like screens and sensors, and if you have an Arduino you might have already used it before without even knowing. Check if your sensor/display/toaster has two pins named SDA and SCL. If it does, it’s probably I2C-compatible, and you might be able to use it with your computer.

[Discontinued] CyanogenMod 12.1 (Android 5.1) for Samsung Galaxy Express AT&T (SGH-I437)

This project has been discontinued!

I’m not going to develop this ROM any more. It takes too much time, and my phone is about to die, which means I’ll be getting a new one. Also, Android 5+ runs too slowly on this hardware. That’s why I’m currently using CyanogenMod 11 (which is back up at download.cyanogenmod.org). I advise you do the same. All changes I made are available on my GitHub.

I finally managed to build CyanogenMod 12.1 for the Galaxy Express! Yayy!

(the header image is still the old one, it hasn’t been updated with the new screenshots)

But it has bugs! Beware! Make sure you have back-ups!

If you’re looking for something more usable, try CyanogenMod 12. Also, make sure you read all the warnings and notices. It’s highly experimental. Continue reading “[Discontinued] CyanogenMod 12.1 (Android 5.1) for Samsung Galaxy Express AT&T (SGH-I437)”

Use an APDS-9930 Ambient Light and Proximity Sensor with Arduino/AVR

Use an APDS-9930 Ambient Light and Proximity Sensor with Arduino/AVR

A few months ago I was looking for a sensor that was able to detect light color. I stumbled into this page and thought well, that seems good to me, so I bought it. When I got it, I was going to throw it away. It just wouldn’t work. I hooked it up to my Arduino Uno with a level shifter, and it didn’t work. I hooked it up to an ATmega8 microcontroller on a breadboard, powered it with my USB serial adaptor using the 3.3V output, and it would still tell me that white light was red, and so was blue light. I checked better and found out I didn’t have an APDS-9960, but an APDS-9930.

I decided to keep it, and write a new library for it 😉 Continue reading “Use an APDS-9930 Ambient Light and Proximity Sensor with Arduino/AVR”

How To Burn LightScribe Labels on Latest Versions of Ubuntu (x86 and x64)

I own a bunch of LightScribe-compatible disk burners, and I always buy LightScribe media because I don’t like handwritten labels. LightScribe-labeled disks look better, maybe more professional, even when it’s just a CD with pirated music.

If you are like me, you might have probably noticed that lately everything seems trying to make us not want to use this awesome technology on Ubuntu. The official LightScribe website is unmaintained/has been hacked, so the LightScribe System Software and the LightScribe Simple Labeler can’t be downloaded; the mirrors that used to host the Debian packages for the LaCie 4L Labeler app are down as well;  even those users who are brave enough to download the RPM from LaCie’s and use alien to debianize it might have noticed that a Segmentation fault makes our beloved app crash.

However, you don’t have to worry any more! I’ve got a solution here for everybody! Continue reading “How To Burn LightScribe Labels on Latest Versions of Ubuntu (x86 and x64)”
