New items added to products

I have added quite a few items to the products recently, so I thought I would list some of them here:

      Description                Device ID                  Price  Link
  • Dual N-CH 60V 4A MOSFET    S4DNF60L  STS4DNF60L       $0.85  MOSFETs
  • N-CH 60V 80A MOSFET        FDB070 FDB070AN06A0        $1.00  MOSFETs
  • N-CH 55V 80A MOSFET D²PAK  STB80NF55-08T4 B80NF55-08  $1.50  MOSFETs
  • Nichia 110 Lumen 1 Watt    NCSL119T                   $0.45  Nichia 119 LEDs
  • Nichia 120 Lumen 1 Watt    NCSW119T                   $0.50  Nichia 119 LEDs
  • Nichia 130 Lumen 1 Watt    NCSW119AT                  $0.55  Nichia 119 LEDs
  • OSRAM 105 Lumen 1 Watt LED LUW W5AM                   $1.75  OSRAM LEDs
  • Nichia RGB LED             NSSM016GT                  $0.85  LEDs
  • Kingbright RGB LED         Kingbright RGB LED         $0.25  LEDs
  • Neodymium Diametric Disc N35H 6x2.5mm 120C            $1.50  AS5040 AS5045 AS5035 AS5043 Sensor Magnets

We will be adding a N35EH version of the Neodymium Diametric Disc 6×2.5mm sensor magnet that will operate at 200C in the next few weeks

Also note that we will be recieving PCBs for the ION Chamber Kit in about a week. We have improved the ion chamber radiation detector kit design to allow use of any can material so no more need to look for tins ( use any old can, like a tuna can for your ion chamber), also improved the adjustment of zeroing the kit. We will put the PCBs and kits up on the site when the instructions are rewritten to accommodate changes to the design. We also acquired a large supply of uranium Vaseline glass beads to use as low radioactive sources for the kits. see kits and supplies for radiation detection here: Radiation detection

Retrofitting a Harbor Freight 60 LED Solar Security Light with 110 Lumen LEDs

We just received a shipment of 110, 120 and 130 Lumen 119 Nichia LEDs. I decided I wanted to try them out, so I replaced 48 of 60 of the LEDs in a Harbor Freight 60 LED solar security light. The replacement took about 30 Minutes to complete.

The Nichia 119 LEDs are available at a very low price here: http://www.madscientisthut.com/Shopping/agora.cgi?Components&user4=Nichia%201W%20LED

Here is a picture of the board with ten of the LEDs replaced (see red circle in picture):

Here it is with 48 of the LEDS replaced, I had to turn the ISO way down to 64 and exposure to 1/210th of second on the camera to keep it from overloading the CCD as you can see in the next two images.

I had to turn the sensitivity of the camera way down to get this image

I can feel heat coming off of the LEDs when this is on now. Wow is it bright!!!! (camera ISO setting at 200, still pretty low, exposure was 1/70th second)

Camera overwhelmed by super bright output
