Guest rasteri Posted January 21, 2016 Share Posted January 21, 2016 A a silly little side project I'm trying to build my own low-profile take on the Focus fader. I'm using the same basic idea that Focus used, but instead of using a slotted photo switch I'm using a photoreflector to make the whole thing a lot smaller. The thing uses a BI Tech/TT Electronics fader as its base. The metal brushes have been removed and replaced with a white sticker to make it reflective, and the carbon track PCB has been replaced with my own stripboard-based board which has a Sharp photoreflector (this one : http://uk.farnell.com/sharp/gp2s60/photointerrupter/dp/1618427) soldered to it. It works great, and IMO feels smoother than the mini innofader. Best part is it costs <£5 in parts! I can see this approach being useful for any projects that don't require fully analogue fader position detection. 8 Quote Link to comment Share on other sites More sharing options...

Guest It'sPhilFromThursdays Posted January 22, 2016 Share Posted January 22, 2016 Rasteri + Backtrack + DJ Focus = nothing but pure win-age for the scratch scene. Dopenezz. Putting on my business advice hat (a jaunty neon green dearstalker) i'll remind you that you can get tax credits for R and D for stuff like this https://www.gov.uk/guidance/corporation-tax-research-and-development-rd-reliefand there are even companies that can help you get the cash for a small cut of the rebate, like these guys who i know http://breakthroughfunding.com/ Quote Link to comment Share on other sites More sharing options...
Guest petesasqwax Posted January 22, 2016 Share Posted January 22, 2016 Would this work in an 05 pro III? Are you planning on making any to sell? Do you need anyone to rigorously test it? Quote Link to comment Share on other sites More sharing options...

DJ Rock Well Posted January 22, 2016 Share Posted January 22, 2016 A portable table with an affordable optical fader would be immense... It would also make the Frisk and Raiden efforts look like what they actually are - a cynical rebranding exercise of tat from the Christmas cracker toy factory. 1 Quote Link to comment Share on other sites More sharing options...

kebzer Posted January 22, 2016 Share Posted January 22, 2016 Rasteri, hat tip for the effort! But what about use wear? Wouldn't the reflective paper worn out quickly? Quote Link to comment Share on other sites More sharing options...
Guest rasteri Posted January 22, 2016 Share Posted January 22, 2016 It'll very likely work with an 05 yeah (the original focus fader did and it works on essentially the same principle), and it definitely works with my cut circuit. Yeah it does seem like we're coming on a golden year of scratch modding - Backtrack with his 50% kit, John Beez with his Fretless Fader, various people with faderboxes. 1 Quote Link to comment Share on other sites More sharing options...
Guest rasteri Posted January 22, 2016 Share Posted January 22, 2016 But what about use wear? Wouldn't the reflective paper worn out quickly? It's a non-contact design so it's not under any mechanical stress. The paper doesn't actually touch the sensor, it sits about a millimetre away. I guess it might become yellowed over time but even then the sensor should pick it up as it would still be significantly more reflective than the environment. And hell we can always use white paint instead of a sticker... Quote Link to comment Share on other sites More sharing options...

Focus Posted January 23, 2016 Share Posted January 23, 2016 100% Support this.... I took a sabbatical and sat under a tree for a few years..came back and the Innofader fooled everyone into thinking that it was the only way? That was one of my biggest disappointments. $120? $150 what da fudge.... Notice that Innofader V2 just got released with sharper cut, why did it take so many years? It's all coo it's business but imho some of the Artistry suffered because people got snookered into using the same ish an not many where doing some coo mods...Andy was working overtime...:-) The Scratch Artist/Djs that just want to show up,cut it up and collect the money are super happy about the Innofader being in every mixer...It's reassuring to get on something familiar anywhere in the world.... To those Artists that want to make their Guitar and connect with it on an Artistic level...It's easy to take apart a fader and add parts....All those circuits the Innofader has are overkill and misdirection...All you need is the sensors...Time to break the monopoly... Full disclosure, my own ish is essentially the same as what Andy is doing but room for everyone. I got a dog in the race so I want this monopoly to stop and create a Paradigm shift.... I believe it's in everyone's best interest to support this shift because new Scratch Products can be created or modded without having to tack on that extra $100 dollars for a Innofader...No Need for that..... Make your own, buy a DIY Upgrade,Purchase a Focus Edition....Get Andy's Nanofader kit and add Contacless Fader on a portabletable or choo choo train...Once that obstacle of price for con-tactless fader is removed, then everything and can be made Scratch Friendly... 3 Quote Link to comment Share on other sites More sharing options...
Focus Posted January 23, 2016 Share Posted January 23, 2016 Ahh, I just gave myself an idear... Maybe I should buy an Innofader Pro, make a video taking it apart, adding sensorsthen cut it up fresh haha...That would be some shhh.. The contrast would be interesting... 2 Quote Link to comment Share on other sites More sharing options...
kebzer Posted January 25, 2016 Share Posted January 25, 2016 Focus, make some faders and count me in first in your pre-order list! All I'm asking extra is for a tension controller, like the one found on the new Pio S9. Quote Link to comment Share on other sites More sharing options...

wax inspektor Posted February 17, 2016 Share Posted February 17, 2016 (edited) Yooooo.... Would you mind sharing what component / photoreflector you are using? - the link does not work for me somehow I tried something with a photoresistor / led a while back... the fader was turning on/off (via reed switch) a LED that's been sitting in a shrink tube with a photoresistor. it was quit fiddly to adjust the distance/ but overall it was kinda ok but the curve was way to soft so I ditched the idea - seems like I wasn't that wrong though - didn't know about photoreflector until today .. guess the whole thing is mono but passive, right? super curious about this cause I love my non-wiper-fader *editgot it ...SHARP GP2S60 PHOTOINTERRUPTER Edited February 17, 2016 by wax inspektor Quote Link to comment Share on other sites More sharing options...
Guest rasteri Posted February 17, 2016 Share Posted February 17, 2016 It's not passive in the way I'm thinking of using it, although I suppose you could use the phototransistor element as a muting transistor... Quote Link to comment Share on other sites More sharing options...
wax inspektor Posted February 18, 2016 Share Posted February 18, 2016 ...so how does the focus fader actually work? is there stuff I could read or is it a secret? Quote Link to comment Share on other sites More sharing options...
