These USB Lamps were sent in by Helen Herd, lead of Design and Technology at the Cardinal Allan Catholic High School done by Year 10 students
Steve Fergusson, the Head of DT at Haywood Academy in Burslem Stoke on Trent, sent us some excellent examples of innovative student designs for Amplifier and Lamp cases. The cases were designed and made by GCSE and A Level Product Design students and display a high level of creativity in all of the Students involved.

Hi Luke, The sequence for the LED used in this kit is as followed: Red, green, blue, yellow, cyan, magenta then back to the beginning of the cycle. As the change is a gentle fade you do get colours between these in the cycle, such as the fade between red and green will produce an orange/yellow glow for a short period before fully changing to green.Posted byon Tuesday, 31 January 2017
Hi Richard, This would provide 6V’s to the kit, the LED on the kit is only rated to 5V’s. As such you would need to use a 3X AA battery cage, this would then provide you with 4.5V’s and this would be fine. An example of the battery cages we do can be viewed here, https://www.kitronik.co.uk/catalogsearch/result/?cat=0&q=3X+AAPosted byon Friday, 9 December 2016
The colour changing LED is part number 3527, https://www.kitronik.co.uk/3527-colour-changing-5mm-diffused-led-750mcd.html. The resistor that is used in the kit is a 0ohm resistor, so either the following part 3003-0R can be used https://www.kitronik.co.uk/c3003-resistor-pack-of-100.html or a wire link can be used.Posted byon Monday, 9 November 2015

As the change is a gentle fade you do get colours between these in the cycle, such as the fade between red and green will produce an orange/yellow glow for a short period before fully changing to green. The time between each change varies depending on what the next colour in the sequence is, so the amount of time the colour stays on for does vary slightly although there isn’t a large difference in time variations.Posted byon Monday, 2 November 2015
The actual width of the PCB is about 16.5mm, as stated on the product page. However there appears to have been a mistake made when the technical diagram were created for the teaching notes. Thank you for pointing this mistake out to us.Posted byon Wednesday, 11 March 2015
The colour changing LED 3527 is designed to run off a 2.7 to 5V supply and contains three LEDs, one for red, green and blue. There is a microcontroller inside the LED that turns on the different LEDs to make the required colour so if you want red then the red LED is turned on, but for purple it is both the red and the blue LED that is turned on. This means that the LED will take twice the power when it is showing purple than when it shows red. Using a current limit resistor with an LED only works when the current it consumes is constant, in this case since the current varies then it isn’t a good idea. It might be possible to get the voltage over the LED to stay in the range 2.7 to 5V however this might not be possible and could be very tricky and even if you managed it the brightness of the LED would vary depending on the colour. So what you should do with the LED is use a 5V supply or regulate to 5V if you must use a 12V supply. A suitable 5V supply is:

The easiest way to do this is to use the Light activated switch circuit, code 2112. You would then need to buy the USB power cable, code 4101 which would be connected to the power terminal on the board, and the colour changing LED, code 3591 which would be connected to the output terminal on the board.Posted byon Tuesday, 10 March 2015
Hi Jo, Yes the kit is safe to set in resin.Posted byon Wednesday, 11 February 2015
We don’t sell any connectors that would connect up with the lead you have. SorryPosted byon Wednesday, 11 February 2015
0voteA: Glad you have it working. Can I ask what was causing it to fail?Posted byon Wednesday, 1 October 2014
0voteA: Hi, what do you mean by blowing up?Posted byon Friday, 26 September 2014
0voteA: You can add another LED in parallel without any issues. No additional resistor is needed as the one that is in there anyway is a 0 Ohm link. The colour changing LED can accept 2.4V - 5V, your USB port will be at 5V.Posted byon Wednesday, 2 July 2014
0voteA: The USB port, the cable and the switch will be fine with the extra current of one additional LED. If you are using a colour changing LED with a standard LED, I?d connect the standard LED and current limit resistor to the board and then connect the colour changing LED to the board afterwards. Whilst the board has a space for a resistor and the kit is supplied with a zero ohm resistor this is nothing more than a wire link. Having connected the standard LED and resistor to the board the flashing LED can be connected across flat edge of the standard LED and the pad on the resistor nearest the mounting hole.Posted byon Tuesday, 8 January 2013
