reg-g innit

i tried to upload a jpg of the same image ..with the same results ( it uploaded the shortcut ) ..the jpg was 73kb ?? not to worry i'll try a different computer next time reg-g

thanks for that ...anyway this is the template looking towards the fretboard ie the 1st string pole is a lot larger than the 6th + the are other elements in the fernandes pickup though http://www.google.co.uk/patents/US5585588 i made the core without the 'side / bottom ' bits ..just the poles and 9mm deep it must be scaled so the strings match up with the poles it works a treat as a basic sustainer fernandes put a lot more into the design with phase shifters /agc / current amplifiers and limiters etc etc so unless a schematic is published of their circuit ( or someone designs something similar ) the true fernandes performance will be hard to emulated i used a lm386 with no preamp but running at 12v from a psu ( i haven't tried it with 9v batteries ) i think any amp with a decent 0/p which will drive an 8ohm load will do??? this for me gave sustain on all 6 strings...job donel jeff beck watch out happy hacksawing reg-g

fernades template.bmp i have dragged and dropped this bmp it is still only a shortcut to my hd i am running xppro 32bit and using google chrome

so i cant now upload an xls document ( it is stored as a link and tries to access my hd instead of opening as microsoft xls document ) DONT GET IT ....WHATS WRONG WITH THE UPLOADER???

the sustainer will work with a lm386 even without the fet preamp the core ( poles ) must be of a 'bar' type divided into 6 poles of different areas the same wire and magnet was used to build a new driver and everything worked as should be ( on all 6 strings ) a 12v psu is the power source since the circuit is not very economically designed power wise ( + it give the 386 a bit more clout ) this is one of the main points of a commercial system..very low power consumption the 'harmonic' mode is not addressed either. but if you want to start making music with it ..it works a treat the coil was wound to 8ohms with 32awg copper wire see xls for core template..it will need scaling to match the guitar string spacing at the fretboard hope this helps one or two to get started

fernades template2.bmp

this is the error message and it is still doing it it does it with bmp or jpg... both files are less than 100kb ' There was a problem processing the uploaded file.Please contact us for assistance ' will try again later

why cant i upload my images??

for anyone who built the sustainer and got frustrated with the lack of response try this since the sustainer didn't work well enough using a stripped down pickup rewound with 32awg copper wire( 8 ohms ) i searched for the fenandes design at the patents office this is the template of the core ( for some reason the image wont upload but will keep trying ) i made the core using a piece of 60mmx 9mmx 3mm mild steel bar ( cut as the template instead of pole pieces ) and it works perfectly on all strings my original circuit based on the lm386 is the the driver amp ( excluding the fet pre amp ) this part of the project now works as intended the electronics now need to be sorted for the harmonics mode etc i am using a 2a 12vpsu instead of batteries at the moment

it seems like the success of this project is the design and build of the driver the patent designs give some insight on how to progress

SUSTAINER PROJECT: has anyone on this forum built a sustainer that works..esp top 3 strings i've built one using the lm386 ( driver amp ) i've rewound a pickup to 8ohms using 32aws wire i've tested it at 12v using 2A psu all i get is the 6th string sustaining ( sometimes the 5th ) the driver is as close to the strings as possible the o/p of the amp is a waveform ( >10v ) going to the driver ( with the driver connected ) i am using 9 guage strings ..the bridge pickup is off a strat is this project a hoax...cause it seems like it

thanks for the info..that explains the variations of i/p wiring of this ic re your comments are there any links to better circuit / driver design this is what i am building to at the moment regards reg
