Hello. I'm looking for this IC to finally build my D/S kit that was sent to me incomplete an eternity ago, ie without the IC (after some emails to FdF without any response, i just abandonned, kissed my dollars goodbye and bought a 14 mW module elsewhere). Now i have some time in my hands i would like to build the driver, i still have the components, which are useless without the IC. Many thanks if you can sell me one, or just indicate me a good source (looks like Sharp doesn't sell it anymore). -- Guillermito (guillermito@pipo.com)

If you are stuck, these obsolete component dealers claim to have some available. I have not dealt with either of them and don't know about their minimum order policies, reliability, etc. etc. http://www.ambass.com/ http://www.aeri.com/ Best of luck, Tom 24.67.253.203

From all the e-mails i've read about D&S lasers, i have come across very few satisfied customers. Frank Defreitas is either a crook or extremely disorganised. Either way, never buy anything from him. 62.31.224.1

Reading the large number of complaints about D&S Lasers, I advise everyone to NEVER buy ANYTHING from F Defreitas 62.31.224.1

Mr. Peters, it sounds like your advice and accusations are based on your ability to read emails. If you've dealt directly with him, why don't you say so? Then your comments may possibly have merit. Do you benefit from this forum? Do you benefit from the information found throughout this web site? Have you listened to the multitude of interviews with prominent people in the field of holography that can be found in the holotalk section? DeFreitas does quite a bit for holography in a large number of other ways too, and has been doing so for many years. I've dealt directly with him and the service was very slow. But I don't think Frank DeFreitas is a crook. With some justification that leaves disorganized. Yes it's a shame for those negatively affected. In many ways there's no excuse. But a blanket attack on someone's character, based indirectly as they evidently are in your case, and especially without acknowledging the big picture, are pretty small. 209.90.161.40

Well, i don't want to stir up some old and bad memories, but the fact is that i ordered a $135 DS laser kit on july 7th 2000. My check was cashed right away. I ordered the diode and the barrel separately from other companies as indicated, and received them a few days later. After waiting and waiting, and a bunch of emails asking what happened without response, i finally received my kit monthes later, october 2000. And then i discovered that there was no IC in it, so the kit was useless. Emails again, just one response, and since then: nothing. We are in 2002. This IC is worth 1 dollar i think. But without it, i cannot do anything. So that's it for my 135 dollars. I hope Mr de Freitas used them well. I'm not even angry anymore - i'm a pretty zen kind of guy. But I personally will never buy anything from him ever. I still like his holotalk and diode laser serie of articles. I was checking his website everyday at this time, waiting for the next article. I found that amazing to do hobby holography with diodes, it was like a dream - no need for a HeNe anymore. I bought his two small booklets, i even asked him about his workshops, because i wanted to participate. So i really trusted him, as i trusted all the holographers from who i bought something (holograms, plates, whatever). He's the only one who abused my trust. Anyway. I don't even care about the money lost. But i don't like the lack of honesty, especially from a fellow holographer. I don't like people who protect themselves behind email silence when there is a problem. I don't like people who start a business and cannot deal with it. Tom B: thanks for these URLs. I already contacted two electronic part dealers which listed the IR3C07 on their sites, and they don't have it. Guillermito (guillermito@pipo.com) 132.183.189.182

A while back, the following link was posted on alt.lasers by Tom Burgess: http://www.laserdrivers.com/ This is a company called iC-Haus Corporation. Later, I saw an ad by them in either Laser Focus World or Photonics Spectra (I can't remember which) which stated that their driver is a "replacement" for the Sharp IR3C07. I don't know if it's pin-for-pin compatible with the IR3C07, or if they have a minimum order policy. If you continue to have troubles getting the IR3C07 or a replacement, I can loan you mine so that you can (at least) test your laser. 216.65.161.235

Jonathan, Most amateur holographers are strapped for cash, and can ill afford to lose their hard earned cash to D & S Lasers. No matter how much good DeFreitas has done for holography, his company is breaking the Federal Trade Commission (FTC) rules on mail order goods: "the Commission's Mail Order Rule requires mail-order merchants to: -- ship orders within the time promised in advertisements for the goods or in catalog listings or, if no time is specified, within 30 days of receiving a "properly completed" order; -- for orders that cannot be shipped on time, notify the consumers of the new shipping dates and give them the option of cancelling for full refunds (for consumers who do not respond, sellers can presume they have agreed to a delay of up to 30 days); -- if a consumer cancels, make a full refund within seven days for cash, check or money-order sales, and within one billing cycle for charged sales; -- for orders where revised shipping dates cannot be met, send consumers second notices and, unless the consumers expressly consent to the second delay, cancel their orders (thus, for second delay notifications, the presumption applicable to the first notification -- that consumers still want the merchandise -- is reversed)." The above statement can be found at http://www.ftc.gov/opa/predawn/F93/mailorder1.htm I suggest that all dissatisfied customers of D & S file their complaints online at http://www.ftc.gov 62.31.64.2
