This is for the Full Wave Converter Board - See here: Full Wave Converter

and
The Super String Shortener Board
View attachment 23483
The FWC is a board that contains 4 diodes set in a configuration to convert a string of LED lights from 1/2 wave to full wave.
The SSS is a board that contains 4 diodes set in a configuration to convert a string of LED lights from 1/2 wave to full wave and spots for 1 or 2 resistors up to 2 Watt. This means you can shorten a string of LEDs as well as rectifying it and keep it all on one board.
NOTE: Each panel contains 54 boards. In other words, the buying unit is one panel. This panel is a 'panelized' PCB in that it contains a subset of smaller PCBs. The smaller PCBs are separated by a v-score in the panel and you literally break the smaller PCBs off from the main PCB panel.
So, when you buy one panel from this group buy, you will be receiving 54 FWCs or 54 SSSs.
There is no option for a smaller quantity of boards.
Pricing Info:
FWC Panel - $3.50 (each FWC costs 6 cents ! 3.50/54 = .065)
SSS Panel - $5.25 (each SSS costs 9 cents ! 5.25/54 = .10)
These prices are based on a minimum of 50 panels of each or 100 panels of one of them. If we order more panels, the price will drop and I will update the prices.
Each FWC or SSS board requires a quantity of 4 * 1n4005/6/7 Diodes. Each panel requires 216 of these diodes.
For the SSS board, you will also need the appropriate sized resistor(s). As you can see in the second picture, the board is set up so that you can only put one resistor in if needed. I've tested this with Vishay 2 Watt resistors and anything that size or smaller will work. Here is a calculator that will help in determining the minimum resistor size.
Both of these boards will fit in a 3/8" shrink tube. The FWC board is approximately 3/8" x 7/8" and the SSS is approximately 7/16" x 1-9/16"
Shipping (US)
Shipping will be done by USPS flat rate priority mail or first class mail if under 13 ounces. Flat rate prices range from $5.30 to $11.15 plus packaging material. I will always try to save you money on shipping. If under 13 ounces, they will ship first class mail in a padded envelope to keep costs down.
Canada and outside North America – Additional shipping fees apply. Please note this in your post and I will get you actual shipping costs.
PayPal
US: PayPal fees will be added: $0.30 + 3%
Non-US: PayPal fees will be added: $0.30 + 4%
Post the number of FWC panels, SSS Panels and bags of Diodes you want.
This Group Buy is limited to the first 100 participants or 400 panels. Once the group buy hits this, or on July 31st, I will close this group buy.
I should receive the panels in the middle of September and you should have them in your hand by the beginning of October.
Please do not edit your post if you want to change your quantity, but rather make a new reply.
Payment will be made by paypal to kmalsom@malsom.net

----------------------------
WayneJ has agreed to supply diodes for the group buy again. The cost will be $7.00 per bag of 250 diodes. Each panel requires 216 diodes so you will need 1 per panel basically. These are also available off ebay or other electronics retailers, but Wayne's come pre-bent to fit.
1 bag of 250 - 1n4007 diodes - $7.00
Please PM me with your address after placing an order in this thread so I can calculate shipping.
