Wiki-spamming is not tolerated, will be removed, so it does NOT even show up in history. Spammers go away now. Visit Preferences to set your user name Summary of change: Since GenBoard/VerThree allows much customizations, you'll find a so called ''rescue kit'' which contains about 100 components, as: * '''resistors''': appr 15 values, 6 pieces of each; except: many 100k so resistor matching for WBO2 pump is simpler; many 1k because of gate resistors; also many 33 Ohm since that makes a faster switching, but only applicable with FETdriver; also many 10k, it might be useful near mid OPA * '''diodes for any GenBoard/Manual/DDFlyback''': 8..10 SMB diodes used for either low or high voltage flyback. These are fast 2A (usually 600V, although voltage doesn't count as long as above 20V) diodes. Read "S2J", "ES2J" or "m124 b14 zp" on the top. In the rescue1 kit for v3.1, and 8 diodes onboard from v3.2 (8 more in the rescue kit, since having these on the place of second diodes is the best option for lowZ - although a shorting wirelet or a transient protection diode mounted with the polarity matching the lowZ drawing also works). * '''diodes for highZ GenBoard/Manual/DDFlyback''': 8 pieces of 20V or 6.8V (text on top reads "332 6V8") SMB transient protection diodes that are only needed for high voltage flyback. These MUST NOT be used with PWMing configured unless they are mounted according to the lowZ configuration (reverse polarity compared to highZ - just see the drawings). * '''LM324D''' custom 'mid' OPA: populating the 3d (on the PCB it's located middle) operational amplifier allows some very special features, only used by experts for now. * LM1815M 1 piece is onboard since v3.1 on primary trigger place, but it can easily be wired to secondary trigger. 2nd LM1815 is not included by default, it is optional, see WebShop. * '''throughole transient protection diode''' (1k5 18 .. 22V) * '''capacitors''' (in so called '''rescue2''' kit) and '''5.1V SOD80 footprint zener''' like for D14 place ---- The new '''resistor-count''' is simple. A '''series''' (almost identical as below) of '''6 resistors from each value'''. Not too critical since the assembly level went up for v3.1: * 15..20 pieces 1002 (10k) * 10..16x102 (1k) IGBT gate resistors are in * 2x183 (18k) * 5x474 (470k) * 3x105 (1M) * 3x472 * (4,7k) * 2x165 (1,6M) * 2x101 (100) * 2x473 (47k) * 2x562 (5,6k) * 2x222 (2,2k), * 3x163 (16k) * 2x203 (20k) * 1x333 (33k) * 2x272 (2,7k) 0,5% resistors (the 5% are within 0.5% in practice too): * 2x 5100 (510) * 10..15x1003 (100k) * 4x2703 (270k) * 2x2401 (2,4k) * 2x7502 (75k) * 2x3902 (39k) ---- Because '''capacitors''' don't have text on them, there are 2 ways to tell their value: * measure (with cap-meter or applying 50..60 Hz sinewave with 10k limiting resistor and measure AC voltage across the resistor, than calc). * '''keying by size, number, tape-material''' The latter means that by examining the cap size (0805 is the smallest we use, 1206 is medium and 1210 is huge), the number of caps and the tape-material (trans is transparent plastic, paper is paper) will tell you the value according to a table. Rescue2 v0.02: The packs posted on Apr 9..10 (Mika P., Dana S., Seppo R., Daniel B., Kevin M.) have the following: 8*220n 0805 50V trans 4*1u 0805 25V trans 4*2.2u 0805 16V trans (taller than the 1u) 4*100n 0805 50V paper 5*10n 0805 50V paper 2*10u 1210 35V trans (huuuge!!) 2*330n 0805 50V trans 2*1n 0805 50V paper 1*10u 1206 10V trans TODO: revise the values for later kits.
