Turning a 1980s typewriter into a Linux terminal
Artillect Sep 10,2022
From the late 1800s to the late 1900s, a typewriter was one of the best tools for writing documents. Sadly, they were largely rendered obsolete by the rise of home computers. I didn’t grow up using a typewriter, but a couple months ago I bought a Brother AX-25 electronic typewriter. It uses a daisy wheel (a spinning wheel with letters molded into it) and a motorized hammer to type text, rather than type bars (or strikers) like in a traditional typewriter. The sound it makes is unmatched eve...

Dedicated Control Board for Mobile Robots with Wheels
silicioslab Sep 09,2022
IntroductionFor a long time we developed several prototypes and teaching kits of mobile robots and we always used different modules to build them.Among these modules, we highlight: module to drive motors, module TP4056 to charge the project's batteries, an Arduino board and a shield for connecting the wires to the Arduino's digital inputs.This amount of modules often generates problems with bad connections and also makes connections more complex, with more wires. Also, they are not feasible to b...

Custom Low Power Arduino Motherboard
cowboydaniel Sep 06,2022
This is a very low power barebones Arduino board, which is a drop in replacement for the Uno.It works exactly the same as the Arduino Uno, only it has digital and analog pin short circuit protection built into the board. It automatically turns off the power hungry components if it detects battery power to lengthen the battery life. It is directly programmable via USB, and my goal is to make it draw as little as 15 milliamps when powered using the VIN pin or the barrel jack.This project is still ...

ATtiny programmer
Berera Sep 06,2022
This is a simple schield for the Arduino uno to program ATtiny 85 or 84 depending on the position of the dipswitch. It can also programm the two microcontroller with an external quarz. The two leds are for the status of the programming. It also has a 3d printed enclosure.

Ultrasonic distance sensor
Iturriaga Sep 06,2022
Ultrasonic Distance MeasureMeasure distances by connecting this device to your smartphone with an USB cable. It has an android app to show the measure. It can measure distances anywhere from 0.01 to 5 meters. Great of measuring 90 degree distances. As it has ultrasonic technology, it is not affected by lighting conditions like laser or camera measurement.Assembling.The assembling is very straight forward. First the Arduino Pro Micro board has to be soldered to the board. Then, you have to bend t...

N64 to Jamma
Tornisiello Sep 06,2022
The N64Jamma emulates two gamepads mapped to a standard Jamma edge connector. Buttons are mapped to be suitable for games such as Killer Instinct Gold and Mortal Kombat Trilogy. Using two onboard dip switches or borne terminal connectors, the directional pad can be configured as digital or analog, making possible to play all sorts of games. Furthermore, by selecting "Encoder" via dip switch, the Jamma inputs Up/Down and Left/Right can be attached to Rotary Encoders, making it possible to play ra...
