  • Fun for the family

    posted by AtilaSendil

    First of all there are more than 12 pieces which is a nice surprise :-) The foam is just the right flexibility. Each package has a a bead to make the ending. There are different colors of strings :-) There are a lot of instructions on the internet on how to braid.
    Nice to pass time and have something. A nice activity for the family :-)
    Buy this and give as gift to family and friends; but master it yourself first to teach them :-)
  • Great DIY repair for singe AA flashlights

    posted by QBranch

    Great to have around for repair of small single AA flashlights. I have four HUGSBY P31 lights (sku: 35078) and unfortunately 3 have failed. Found out that the emitter and switch are fine, so it must be the emitter board. So I found these on DX and ordered 5. These fixed all 3 of my P31 lights. BUT be aware that 2 of the 5 sent were 3 mode boards (Hi-Lo-Flash) and 3 were 1 mode (Off-On). The SKU stickers on the zip baggies were identical (128096). Note that the black boards with a larger baggies were 3 mode and the green boards with small baggies were 1 mode.
    Items got sent in a bubble mailer envelope and 1 emiiter got smashed.
    Great DIY repair board and to have some around for spare.
  • Good DC input buck driver for LED currents up to 2A

    posted by lm833n

    - Capable of LED currents up to 2A; preset at 1.8A- Wide DC input voltage of 5~40V- Connections are well marked on PCB- External MOSFET (20N06, 0.046ohm max) and schottky doides (SS54, big!) mounted on one side, can easily attach to heatsink using thermal adhesive eg sku.135352
    - Uses the QX5241a chip. Vref is 205mV, Rsense are two paralleled 0.22ohm to get about 1.8A output.- Can be modified for lower current: I=(Vref)/(Rsense)eg 0.14ohm gives about 1.46ASuitable 1.8A LEDs: sku.189569, sku.101095, XM-L and XM-L2 (reduced brightness)1.5A LEDs: sku.81837, sku.199872, sku.203212
    If you have a DC supply and find the PT4115 lacking juice, this 5241a driver might be the answer.
  • does its job

    posted by rayho

    - works as described- pretty cheap for two
    bought this to repair a DOA Waterproof SA-R2 Stainless Steel CREE XP-E R2 WC 5-Mode Memory 240-Lumen LED Flashlight (1*AAA) sku#47661, so it does fit with a little bit of filing
    great option for repairing AAA battery flashlights, does its job, i didn't need the 5 different modes anyways
  • Bright RGB LED for Arduino projects

    posted by Odimljeno

    - very bright light (almost too bright as it is hard to look at it directly) - works with Arduino (example on how to test it: http://www.arduino.cc/en/Tutorial/ColorCrossfader) - nice and compact PCB with SMD LED - good build quality
    This is not going in some project, I just like playing with this colorful thing and that the entire reason I bought it. :-)
    If the price is good for you buy it.
