UPDATE: Mazzilli Flyback Driver Boards Are Done
***NOTE*** - I am sold out of the type 2 boards, and running low in type 1 boards and irfp250 mosfets. I do not plan to make another round of these, so whats left is what is left. Per the rest of the thread, I have not updated it in over a year, so quantities are approximate, please inquire if you are interested.
Sorry for the long wait (what has it been, like 3 years now?) but I never really had a lot of interest in boards. I finally got an order for 4 of them, so I decided to start etching. I still need to seperate the boards and drill the holes, but you get the idea...
Type 1- Compact Flyback Driver Board: These boards are designed essentially as a way to organize the wires for a mazzilli driver, and were optimized for high power drivers. They are small, and have an extremely low inductance layout (you can see by the traces, there isn't even any right angles in the power traces), but they have their drawbacks; mainly that the supply choke (between v+ and the center tap of the transformer) is not included on the board, the tank capacitor is not included, and one of the fets is mirrored vs the other fet. The inductor/capacitor were left off the board because they don't really have any reason to be on the board, the series inductor doesn't connect to the fets at all, and the tank capacitor needs to be connected directly to the primary of the transformer for high power drivers. The mirrored fet was to minimise inductance/resistance of the board, and using individual heatsinks (I recoment mouser 567-657-20ABP which is good for over 500w of output power without fan and costs about $2). This board can handle over a kw of power, and was made out of extreemly thick 4oz copper (it is a pain to work with, but you will never vaporise a trace with that stuff) and if you need to you can glob a bunch of solder across the power traces.
These boards are $5 a piece for a drilled board, $1 shipping in the US. I have 2 in stock and 4 questionable ones that I am going to sell as an assembled board (with zener diode, 10k resistor, uf4007 diodes, and 910r pullup resistors) for $10 a board, free shipping ($6 off normal price).
Type 2 - Complete Flyback Driver This board is more of a 'standard' flyback driver, that has provisions to mount all of the components except for the flyback ad power supply(s) on the board, and has both of the fets facing the same direction. It has more inductance and resistance than the compact boards, but it should be able to run any of the flybacks I have seen on this forum to destruction before it breaks a sweat (if you rewound your flyback for highers powers, go for the compact driver, you won't be let down). Since these are larger I am charging $10 for the board itself, plus $1 shipping. Sold Out.
As before, I also stock all of the parts necessary to make a complete mazzilli driver; and very reasonable prices:
I decided to make 2 different types, outlined below: (moved from botttom of post) ZVS KITS: a starter kit of the parts to build this circuit 2x irfp250 4x uf4007 4x 10v zener 2x 10Kr resistor 2x 470r resistor **NOTE- all current drivers ship with 910r resistors to prevent parestic oscillations, if you want 470r ones make note when ordering 1x PF2125-ND 1.2uf tank cap (tested good for 300w for long runs runs, and >500w for short runs; the limits of my flybacks...) 1x t130-6 core with 80 turns of 20awg magnet wire (seems to be good for 20 amps...) 2x little heat sinks for the fets shipped anywhere in the world for $25
A board for it to all go on =$5
Then the rebuild kits are $10+ shipping which include 2 more ifrp250s and a new set of uf4007s, 10v zeners and a new tank cap.
I also have 25a bridge rectifiers for $5 if you need one of those too... shipped anywhere in the world for $20
NOTE: make sure to read the whole thread, there is more information in later posts!
I have collected quite a stockpile of components as the years have passed by, and I have decided that I will not be able to use all of them in my life, so I am letting you guys at them. I am doing this as a service to you, do not complain that I am offering a diode for $.1 that could be had for $.06 if you order 10k of them from farichild, I am listing them at what I would pay for them, no more no less. I would prefer if you only bought stuff from this list if you are working on a project or having a hard time finding a part, and not just buy all of my 40n60's because they are cheaper than mouser, but if that is what you want to do then so be it, I just ask that you leave a few for me ;D
I will ship all parts first class mail/priority mail for US inhabitants, usps global mail for foreigners. If you want me to ship overnight/etc say so and I will ship anything that I can do without leaving my house. I will only charge you the cost of the components you ordered + shipping. I will accept paypal, credit card, cash, or check (preferably one of the first two). All of the components are new to the best of my knowledge, but I can't guarantee anything because there is no way to tell if the component was doa or killed by the user. Except for the parts like 555s that I have hundreds of, try to limit yourself to what you need, don’t stock up on parts here. If you really want to buy me out, please leave me with a few for my self/others.
parts are listed in part number - description - package - price - quantity on hand low power diodes: uf4007 - fast 1A/1Kv diode - do-141 - $.1 - ~20 1n4007 - 1A/1Kv diode - do-141 - $.05 - ~500 1n4003 - 1A/300v diode - do-141 - $.03 - ~150 na - generic signal diodes - assorted- $.01 - ~100
low power transistors: 2n3904 general purpose npn transistor - to-92 - $.05 - 3 2n3906 - general purpose pnp transistor - to-92 - $.05 - ~100 na - assorted npn transistors - to-92 - $.02 - ~20 na - assorted pnp transistors - to-92 - $.02 - ~20
Capacitors: 2 92mf 535v AC oil caps; only about 15J, but they are huge, 4.5x3.5x9"tall $$7/cap
SMD: I have about 200 diferent types of smd resistors/caps in stock, over 2000 components total. Resistors 1% and 5% from 0 ohm to 2meg in 0805 and 0402 packages Ceramics from 1pf to 2.2uf in packages from 0402 to 1210 Tants from 100nf to 68uf in varying packages. green and red leds that are brighter than an average indicator, but much less than the ultrabrights around (probably enough light to illuminate a 3" circle enough to read by). As with all of my items I don't want you to buy me out as this is my personal stash of parts, but I encourage you buying the parts you need (with a few extras of course) for a project (considering how frigging expensive these can be from digikey). I am thinking $.10 for resistors/ceramic caps up to 100nf, up to $1 for a 68ufd tant cap, and I am thinking $.25/led. Just pm what you need and I will give you a quote.
I also have some odds and ends, smd ntc thermistors, lm555's, and smd UCC27321/2 and UCC 37321/2 in the thermal enhanced package for those micro gate drivers (me thinks $1/piece) and a few inductors that go with the maxim boost converters I have...
Variable Resistors: I have 1, 12, and 25 turn pots... I have single turn pots from 100 to values in the meg ohms, about $.5/piece I have 12 turns in smd pacakges (gull wing, or a more normal looking one with the pins bent over) in values from 500 to 500k, about $3/piece. the gull wing ones are the CM4 series, I don't know with the others The 25 turn ones are mostly bournes 3299 series, from 500 to 100k, about $3/piece.
Other Stuff: (pm for availability) FLYBACKS (I have a variety of diferent types large and small, acc DC, many priced arround $5) High power igbt bricks small DC brushed/brushless motors ($1/oz) pico fuses (1/4, 1/2, 1, 2, 4, 7 amp fast blow 1/2, 1, 4, 7 slow-blo) - $.25 - 20 of each inductors - $2/0z assorted wire - $.75/0z 1/8" stereo jacks/plugs or 1/4" RCA jacks/plugs - $1/pair - ~20 pairs 3/8"od copper pipe - $1/foot - 5ft through hole/smt resistors/caps 1ohm - 100Mohm/1pf LEDs wire wrap wire/boards perf boards project boxes solder solar cells (Si single crystal/amorphous & GaAs cells (~30% efficiency!) computer parts heat sinks magnets etc
LASER diode: My asking prices are $60 for a 20w bar, $150 for a mounted one on a 1" mount (big block-o-copper that you just bolt down).
I also have some small (I think 20mw at 1550nm) DFB lasers (which means that they have a very small line width, like 1nm). I have no data other then that they work (I have mounted a few). Thinking about $5 a piece, add $50 for mounting on a small copper plate (like 10mm by 6mm by 3mm thick).
Finally, I have googles for 532nm, 808nm, 1064nm, 1550/1310nm, probably some other wavelengths (uv and ruby quoted) if anyone needs them. $60 new/$30 used.
Trading is cool too ;) ssy-1's are worth $90 of credit. Subtract $30 if you blew out the q-switch (if you put a lens that focuses it at about 1inch away and fire at 20j and you don't get a small floating spark then the q-switch is dead). If you have a 1.6mm nd:yag rod (for diode pumping) I am all ears, or even better a mount for a 1.2mm rod. (I have a 1.6mm mount, but a 1.2mm rod, arrg)
I am soon going to be able to sell zvs and tl494 based pcbs. I am also having some fullbridges (with to-247 fets) and PLL sstc drivers (cd4056 based) made. If you want them pm me asap.
pcb board manufacturing I can now offer PCB manufacturing! The stock I have around is 6" by 8" (plasmasonic anyone?) double sided 4oz (really heavy duty) copper, but if I get much interest I will look into getting some 1oz double/single sided stock. I think that I have a small (like 6x6) piece of 2oz double sided if you want something thinner right now. I use the press-n-peel transfer method, using HH4CLO4 to etch with and have made traces .5mm no problem, I still need to try and see how small I can go (just haven't got around to it). It costs about $.05/in^2 to make a board, and holes are in theory free (I have .025", .033", and .04' carbide bits and like .08 to .5 in hss; again if I get much interest I will get some more sizes). I am thinking like a $10 'setup fee' per board, and something like $1/in^2 for boards under 10in^2, and $.5/in^2 for boards bigger, but it really depends on the complexity of the board... PM me for a quote. I promise that I am cheaper than any other service (and if you can find someone cheaper please tell me)

I recently acquired a huge assortment of smd resistors/caps (about 200 types, 2000 parts), resistors 1% and 5% from 0 ohm to 2meg in 0805 and 0402 packages, ceramics from 1pf to 2.2uf in packages from 0402 to 1210, and tants from 100nf to 68uf in varying packages. As with all of my items I don't want you to buy me out as this is my personal stash of parts, but I encourage you buying the parts you need (with a few extras of course) for a project (considering how frigging expensive these can be from digikey).

I also have a ton (well closer to .00015 ton) of trimmer pots. I have 12 turn ones in a gull wing pacakge 2k, 10k, and 500k, and in a more clasic normal 12 turn trimmer pacakge with the pins bent in 500, 10k, 50k, 100k. The gull wing ones are digikey p/n SM4WXXX-ND (XXX is the 3 digit code for the resitance, cap style) but I don't have a p/n for the other type. Just imagine a 12 turn top adjust trimmer with the pins bent over so you can use it smd. If smd isn't your syle, I have leaded ones too. 25 turn 3/8" ones (bournes 3299 series mostly) in 100, 500, 1k, 20k, and 100k... And of curse for those adjustments where you only need a single turn I have single turn pots from 100 to meg ohms... Pricing varies widley, the multiturns are usually about $3/piece, the singles more like $.5/piece. PM me for a quote...
I also have 2 xecom XE900S-500 900mhz 76.8kb/s half duplex wireless modems (0.5w tx, -100dBm rx) with a few a/d and digital i/o in them, that are SUPPOSED to give a 20 mile link in open air (although I couldn't get more than a few hundred feet, so I hope you have better luck) that I paid $75 a piece for from xecom. One of them is in pretty good shape, one of them I had to redo the power/serial pins since they broke off (mechanical stress) by putting in some push in pins, and using some 30awg wire to make the connections... Last I checked it still had continuity, although that might have changed in the year that it sat in a box. I also have the antenna that xecom sells for them (looks just like a 2.4ghz antenna like on a phone, except purple and it is for 900mhz). Would love $100 for the pair, very negotiable price/easy to trade.
And... I am now going to offer pcb board manufacturing The stock I have around is 6" by 8" (plasmasonic anyone?) double sided 4oz (really heavy duty) copper, but if I get much interest I will look into getting some 1oz double/single sided stock. I think that I have a small (like 6x6) piece of 2oz double sided if you want something thinner right now.

PM me for a quote. I promise that I am cheaper than any other service (and if you can find someone cheaper please tell me)
edit: I also added my 1a/15v (ka7815) regulators ($.5/piece) and 12v/100ma (78L12) -12v/100ma (79L12) and 5v/100ma (78L05) for $.25/piece

A few updates: !. I added my high power laser diodes to the main post (from ) 2. I can provide complete mazzilli kits (including a pcb and flyback, heck I can even assemble/test it) but I am clean out of irfp250's, If I get enough interest I can order more, but as it is I have WAY to much stock on hand and need to get rid of fets, not buy more. Or, I could hook you up with one of the many fine fets I already offer, but just between you and me, if you don't want to run >50v in those irfp250s kill just about any other fet performance wise.

Update: Due to renewed interist in the mazzilli driver flyback kits, I have created a PCB layout and acquired all components necessary for creating a few complete drivers (either in kit or assembled form).
Pricing is the same as before, $20 for the component kit, $5 for the PCB, $5 for a flyback transformer, and if you need it $10 for assembly/test. Shipping has gone up, I think it is $4.75 for a 1lb box these days, will check when you make an order.

I haven't etched any boards, still looking to see how many of these I am going to need to make. I do know that the boards will be single sided 2oz copper, but for high powers I highly recomend building up the traces with a thick layer of solder. For extreemly high powers (>500w or so) I would recomend not populating the tank capacitor (the one between the FETs) and rather connecting your primary directly to the capacitors pads, and putting the capacitor directly across the primary of your transformer. Using this method I would expect this driver to be capable of running in excess of 1kw of power, although I have not tested this particular board at these power levels. Also, provisions were made to use seperate power supplies for the gate and the prime fet power, if you are only planning to use the driver at low voltage (<20v) you can add a jumper, but if you want to run the driver up to its maximum voltage rating (about 50v for the included IRFP250 fets) you will need to add some kind of external 12v power supply. One last note, is that one of the fets is mirrored in the pcb layout, because this allows a much lower inductance layout. This means that you must bolt on fet on top of your heatsink, and one on the botom of the heatsink (or if you use my kits I supply 2 seperate heatsinks which alleviates the problem)

I may be interested. Do you have a picture of a completed circuit on your board? I've got parts on the way and just want to make sure everything will fit. Thanks
