I've send email. Frans.

Hello Frans, My name is Libby. I wrote to you on your Flickr account on the 8th December, 2010. I work for a company called Toadshow Pty Ltd. We have been contracted to design and produce an Educational Centre for the Hinze Dam located in the hinterland of the Gold Coast. We would like to use two of you images in the display. My email address is libby@toadshow.com.au. I look forward to hearing from you. Regards Libby Jones

Excellent, it's a wonderful gallery.

Hi Foto Opa, I have my coil gun operational. I had to add an anti-parallel diode after blowing up an IGBT. Optimal pulse duration is 7 ms, projectile speed rather slow, around 7 m/s. I use about 1 mF of capacitance, coil is 70 Ohm, I do not know it inductance, 200V potential. The thing is controlled through the parallel port of a Linux PC, together with flash, shutter, valve, pump and maybe other stuff in the future. I have no interesting photo's taken with the use of the gun yet, just some measurements.

Hi Lex, Een blusdiode op je magneet zetten maakt je coilgun onbruikbaar. Daarom ga ik niet hoger dan 150V. Maar er zijn fets die nog een hogere spanning aankunnen zoals de IRF840. Je resolutie tot 1MHz zal voldoende zijn. Je elco's ook, het is meer een kwestie van de juiste inductie te hebben om voldoende stroom door je spoel te krijgen. Als het voor fotoopnames is hoef het ook niet supersnel te vliegen want dan heb je nog meer problemen voor een scherpe foto en juiste timing. Ik programeer alles in verilog. Gaat heel snel, is eenvoudig en alle taken gaan parallel. In de nieuwe ontwerpen worden voor bepaalde eenvoudige hulpfunctie's nu ook de AVR reeks controllers gebruikt. Vooral waar analoog in voorkomt. Zie ook mijn flicker account: http://www.flickr.com/photos/fotoopa_hs/ Daar staat ook heel veel informatie op. fotoopa.

Beste Foto Opa, Hartelijk bedankt voor deze informatie. Ik heb nog twee flistelco's 350V 1000uF liggen die ik parallel wil zetten. Ik kan dan ook nog tot 250 of 300V gaan. Ik zal eens naar de specs van jouw fets kijken. Gebruik je nog een diode om de inductiepuls op te vangen? Met mijn PC kan ik via de parallelle poort stabiel 1 MHz produceren onder single user Linux. Ik denk dat ik dus voldoende resolutie heb om e.e.a. reproduceerbaar aan te sturen. Wel cool om het met een FPGA systeem aan te besturen. Programmeer je voor al je functies apart een circuit in bv VHDL? Verder ben ik een grote bewonderaar van de mechanische werk. Zelf ben ik meer een software man, dus dat gedeelte is voor mij echt een brug te ver. Het summum vond ik wel je eigen sluiter die je zwaar overstuurt om korte responstijden te komen. Met vriendelijke groeten, Lex (Papa Razz i volgens mijn kinderen)

Hallo Lex, Voor de coilgun gebruik ik een flash elco van 820 uF die opgeladen wordt tot 150V. Opladen gebeurt door 2 tansfo's rug aan rug en de secondaires zijn zo verbonden dat er ongeveer max 150V gelijkgericht op de elco kan komen. De oplaadstroom wordt met een weerstand beperkt. De spoel is een bestaande kleine 6V magneet waar ik die 150V opbreng via 2 parallel geschakelde fets IRF740. De coilgun kan enkel goed werken als je de juiste pulsduur stuurt op de fets. Bij mij is die tijd in de buurt van 2 msec. Die tijd moet je zelf uitproberen in functie van de magneet. Het projectiel moet vrij nauwkeurig op dezelfde plaats liggen bij het starten. Ik gebruik altijd mijn FPGA module omdat daar de nauwkeurigheid van de tijden beter dan 100 nsec is. Om goede resultaten te bekomen moet je best een timer resolutie hebben van 10 usec of beter. Te veel variatie's geven onstabiele resultaten. fotoopa

Hoi foto opa, I am a great fan of your work, very challenging, time consuming as well I bet. I have been making some high speed work as well, if you are interested, see http://members.chello.nl/a.augusteijn1/Gallery/High%20speed/index.html I now use a PC through it's parallel port to control shutter, flash and a valve. I used an air rifle up to now using a phototransistor to trigger the circuit when a bullet exited the rifle. I would like to experiment with a coil gun though, do you have so more data on you device? Can it compete (power wise/precision) with a rifle? Do you charge a capacitor bank, if so, which voltage and capacity? I expect timing is critical, as you want the magnetic field to be low when the projectile is in the middle of the coil, such that it will not be pulled back again. I hope you will continue this amazing work for a long time to come to enjoy all of us. Lex (from Eindhoven).

Your water figures are absolutely amazing, I was so impressed that I had to try! I made a different setup, with a sound trigger, and got similar results like your early ones. What I can't reproduce yet is that flower shapes you have, all mine look like just water droplets... how do you do these? I notice you use a metal ring on some... do you put the drops around and inside the ring? This is my setup with detailed description: http://www.flickr.com/photos/chavals/2249963726/ And the results: http://www.flickr.com/photos/chavals/sets/72157603971576913/

Thanks Gus, But from now on I've to works day's and day's on a new setup and than only a few hours later I've the pictures and it's finisch. Frans.

Well said Soenda! Fotoopa is forever pressing the limits of technique and art. Just when I think his journey is at end, he comes up with another 'rabbit out of the hat' ;-) Excellent work here; I'll be around. Regards - g

Thanks Soendra for the nice words! I work hard now on the new concept. I have a dream to realise completely new droplets combinations. But if this works I think to have found a ingenuity way to realise it. Like always I like to share this methodology. I need only a few more day's or weeks to make the final tests.

We casual viewers could easily fail to recognize the magic you are making here. In its thumbnail version, the flowchart's significance escaped me. I mistook it for a circuit board plan. However, having had the good fortune to see the miraculous work you did with capturing insect flight, I should have taken a closer look. Photographic alchemy is underway here. Once again you are industriously laboring to turn light rays into photographic gold. I can't help smiling in anticipation of droplet photos like none ever seen before. Now that I know what's brewing, I'll keep a much closer watch. It's going to be wonderful!
