This requires the same Arduino setup as yesterday’s project, so follow the instructions there. The other side of the button goes to PD3, and a 10K pull up resistor from PD3 to +5V. Anode of the LED to +5V, and then one side of the button to Ground. Emitter of that transistor to Ground, and Collector of it to the cathode side of the LED in the button. So you’ve got PD0 of the USB Wildcard to a 1K resistor, and that to the base of a 2N3904 transistor. The following is a very rough schematic of the button: Replace the resistor with a 100 ohm unit, and reassemble. Unwind the leads from the plastic frame, and you can pull the LED and resistor out of the assembly. Refer to the photos above for how to disassemble it, but you basically remove the switch assembly by twisting it, and then pull out the LED assembly from the top of that. If you try to run the LED in the button on 5V, it will be dim - it’s set up to use 12V, so the resistor is much too large for 5V operation. There is now a variety of Sparkbooth compatible USB buttons to choose from. I used a SparkFun Big Dome Button, which needs a modification to work properly. It uses that along with a few other components to drive the LED and read the button. This is another one based on the USB Wildcard. Displays on-screen keyboard for touchscreens. It fades the LED in button on and off to attract attention, and when pressed, simulates hitting the spacebar to trigger photo taking. Lock mode hides the button toolbar, prevents display of any settings, and exiting of fullscreen. What we’ve come up with here is just such a button, using the USB Wildcard board. But wiring up a nice button takes some effort. Building one yourself is definitely an option, especially if you already have a decent camera and a computer you can dedicate to it. Photobooths are incredibly popular for weddings and other events these days, but are also incredibly expensive. Still playing catch up, our next project is for those building a photobooth: a button to trigger it. In June 1963, Francisco Franco inaugurated the Military Armor Museum, the official name given to the institution.Photobooth Button: Open Hardware Advent Calendar Day 18 Later in the 20th century, the castle became a military museum. Companys was executed upon orders from the Spanish State at Montjuïc Castle in 1940. The castle is infamous in Catalan history books because of its role in the civil war from 1936 to 1939, when both sides of the conflict imprisoned, tortured and shot political prisoners at Montjuïc, among them Lluís Companys, who was the president of the Generalitat of Catalonia during the Spanish Civil War. In the late 19th century, Montjuïc was synonymous with barbarism based on the torture of anarchists and others imprisoned there. Since then the Montjuïc cannons have bombarded the city and its citizens on various occasions, and Montjuïc has been used as a prison and torture centre repeatedly for three centuries. In the last 350 years Montjuïc Castle has played a decisive role in the history of Barcelona, becoming a symbol after the Catalan defeat to Spain in 1714, date that has become of significant importance. Southwell was afterwards made Governor of the castle. In the Siege of Barcelona (1705) the fortress was captured by the British 6th Regiment of Foot led by Lt.-Col William Southwell, paving the way for the siege of Barcelona itself. In his honor, the King of Spain granted the Colonel the death title of Viscount Montjuïc.įifty years later, in 1694, new bastions and battlements were erected and the fortress became a castle. At that battle, Colonel Shane O'Neill or known in Spain as Prince Juan O'Neill, died leading his regiment during the Battle of Montjuic near Barcelona, dying from a musket-ball wound to his chest near the town of Castelldefels. The Spanish recaptured several cities, but they were defeated at the Battle of Montjuïc by Catalan, led by Francesc de Tamarit. On orders from the King of Spain, Pedro Fajardo, heading an army of 26,000 men, proceeded to crush the revolt. A year later, in January 1641, the fort saw its first battle, during the Catalan Revolt when the Principality of Catalonia challenged Spain's authority. The foundation stone for the basic fortification was laid out in 1640.
