Hi, is it possible to replace the switch with an other switch? I was thinking to wire up another switch in place of the current switch, in order to move the switch to a more appropriate location. In other words adding wires to extend the switch location. ( I hope that makes sense) I'm using this torch for a lighting project as opposed to using it just as a torch Thanks

    Hi Sarah, That would be fine, you could just use the switch that we supply but just link it to the board with wires as you say instead of connecting it direct. As long as it is connected the same as it would be if soldered to the board it wouldn’t be an issue.

can the battery be replaced with a plug? or a usb cable?


  • Posted by Michael Lockhart on Thursday, 1 December 2016

    Hi Sarah, Yes it is possible to swap the battery holder for a 12V power supply. If you wanted to use a USB port/plug to power it you would have to change the resistor to suit as a USB port outputs 5V’s and the resistor was chosen based on a 12V supply.

Using Ohms law wouldn't an 820 ohm resistor be suitable instead of the 680 ohm you supply?


  • Posted by Michael Lockhart on Friday, 19 February 2016

    The LED draws around 10mA, the resistor has a voltage drop of 8.8V. As such by using Ohms law you would get the following, R=V/I, R=8.8/0.010 giving R a value of 880Ohm. However resistors come in preferred values, as such the closest preferred value that is available is 680Ohm. This still provides enough resistance to protect the LED. The video on the product page explains why this value resistor is used in more detail.

Hi, is it possible to use a bigger/brighter/more leds with this? if so which ones?


  • Posted by Geoff Hampson on Wednesday, 30 December 2015

    Yes product:

    Is 17,500mCd compared to the torch LED which is 5,000mCd. They both have the same forward voltage, current requirements and viewing angle so you could just drop it straight in to give you a torch that is about 3.5 times brighter.

Hi there, do you have a 2D design housing template for the torch kit Product Code: 2114, or any other housing solutions? Kind regards Simon Fowler Mayflower High School


  • Posted by Michael Lockhart on Tuesday, 10 February 2015

    Unfortunately we don’t have any housing templates for this kit. We do have a few examples that other schools have done to house the unit, if you see the media section on the product page. The easiest housing solution is to use some acrylic tubing to house the unit, or you could use our new Polypropylene sheet.
