It'll also have an amplitude of 5V (I use SN74-series Schmitt triggers which generally get a bit unhappy if you power them with more than 5.5V)\u003c\/p\u003e\n\u003cp\u003eThere is, however, a catch - the potentiometer only gives you a certain amount of control over the length of the trigger. Basically from 'short' to 'not quite as short'. If you're after something that will generate a trigger of exactly \u003cem\u003en\u003c\/em\u003e milliseconds in length then I'm afraid this isn't the droid you're looking for. However, if you want to take a long signal and make a shorter one to, say, feed into an envelope generator or sequencer, then it'll do you just fine.\u003c\/p\u003e\n\u003cp\u003eIf you're up for a bit of technical vivisection then you can always replace the 1nF film capacitor with one of a different size - larger values will yield longer triggers, but don't go crazy; anything more than 10nF is probably overkill. Resistor R2 (470k) controls the minimum length of the pulse ie. when the length pot is fully counterclockwise - a higher value, such as 1M, would result in a longer 'default' pulse. R2 is an 0603-sized device which is relatively straightforward to hand-solder.\u003c\/p\u003e\n\u003cp\u003e2HP wide, with Euro-to-JST power adapter included.\u003c\/p\u003e","brand":"York Modular","offers":[{"title":"Default Title","offer_id":57553072095610,"sku":null,"price":21.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0274\/7115\/1213\/files\/IMG20261113183539.jpg?v=1794597127","url":"https:\/\/www.yorkmodular.co.uk\/products\/g2t-single-channel-gate-to-trigger-module-2hp","provider":"York Modular","version":"1.0","type":"link"}
