HACKADAY LINKS: APRIL 9, 2017
[Federico Musto], one of the Arduinos in the Arduino vs. Arduino saga (which lastly concerned an end last September) may have fabricated his academic record. This news comes from Wired, offering files from the registrars at MIT as well as NYU specifying [Musto] never went to these institutions. because this story came out, [Musto] has edited …
FORKNIFE, ANDROID G1 managed ROBOT
When we first saw [Jeffrey Nelson]’s G1 based robot we immediately wondered what the transfer for the controls was. The G1‘s hardware supports USB On-The-Go, but it’s not implemented in Android yet. It turns out he’s actually sending commands by using DTMF tones through the headphone adapter. The audio jack is linked to a DTMF …
RASPBERRY PI REPLACES A VOLVO NAV SYSTEM
[Reinis] has a Volvo S80. one of the dashboard features it includes is a 6.5″ LCD screen which periscopes as much as utilize as a navigation system. The issue is that Volvo stopped making maps for it around five years back as well as there are no maps whatsoever for Latvia where he lives. So …
IR BASED AUGMENTED reality
For a final design project, [Frank] and his group took on an augmented reality project. The goal was to make objects interactively controllable by pointing a smartphone at them. Their solution was Augmented reality universal Controller and Identifier (ARUCI). The system locates controllable objects by sensing IR beacons that contain identifiers for each object. The IR is received …
MINIMALISTIC 555 adding machine
how many 555 timers does it take to add up two 10 digit numbers? [Alan’s] 555 adding machine does it with 102 of them, he designed the machine as an extreme entry to the 555 contest and the original plan was to make it even more complicated. This machine uses the 555’s to implement a …
RF ROBOT managed FROM A terminal window
This robot can be managed from the terminal window of your computer. You can see a manilla-colored board mounted between the wheels. This is the RF receiver which has rather a long antenna that we’ve cropped out to get a much better look at the bot itself. [Ashish] chosen up an RF transmitter/receiver pair for …
[FRAN’S] PCB ETCHING techniques
We think that anyone who’s done at-home PCB fabrication will appreciate the tidiness that [Fran] maintains throughout her etching process. She recently posted a three-part video tutorial which showcases her techniques. As you can see in the screenshot above, her routines reek of superior laboratory skills. Regular readers can probably guess what circuit she’s etching. It’s the …
AN OVERKILL NETWORK ADAPTER FOR RETROCOMPUTERS
If you want to get an old Apple, Commodore 64, Amiga, or any type of other retrocomputer up on the Internet, this is for you. [Stian] had an Amiga 500 lying around as well as wished to put it on a network. The A500 isn’t expandable, so he needed to look at some kind of …
ROLLING YOUR own minimal USB TO SERIAL ARDUINO PROGRAMMER
[Hans Peter] wanted to relocation away from using full Arduino boards in his projects. one of the components he rarely used after the development stage is the USB hardware. once the firmware is flashed to the chip he didn’t need it any longer. So he tried his hand with some really small SMD parts by …

DIY SPECTROPHOTOMETER
[Charlie] has been making a diy Spectrophotometer, as well as while it is a “shambling mess of information-age technology!” it is still much much better than ours. Focused around an arduino, bits of lego, as well as a flashlight, this innovative gadget rotates a diffraction grating (flake of compact disc) aimed at a picture resistor. …
