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.

What colours does the LED go through
Posted byon Tuesday, 31 January 2017
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.
would this be OK powered from a 2235 battery pack?

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+AA
Could you tell me which specific colour changing LED is used and which resistors (part numbers if possible) so I can order a number of spares for use by those who manage to break/blow the one's in the kit, rather than taking parts out of other kits. Many thanks.

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.
Can you tell me what colours the LED changes through please?

The sequence for the colour changing LED used in the 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. 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.
The dimensions stated on the technical drawing of the PCB suggest that the LED is obstructing the 3.3mm mounting hole closest to it? Can you please confirm the correct dimensions of the PCB stating accurately the mounting hole positions and position of the LED. e.g. Your drawing states a 3.3mm mounting hole 4mm from the PCB edge with a 5mm diameter LED 4.5mm from the opposing PCB edge. Therefore 4+1.65+4.5+2.5=12.65mm. The PCB is 11.5mm wide. I realise there is 0.5mm offset in the adjacent direction but this doesn't give any room for the head of a fixing in the mounting hole?

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.
