PCB AND HEX FILES FOR PROJECTS

These files are for personal use only and should not be published elsewhere.

No liability will be taken for anything involving the use of these items.

To save the files, right-click them and select "save link as..." to save them to your system. The PCB layout files can be printed with the viewer linked to below, and the HEX files can be used with Microchip programmers like the PICkit2/3.



GERBER ZIP FILES


These zipped files contain the correctly named files for most PCB manufacturers. When uploaded to the order page of companies like JLCPCB as a single file they should auto-fill most of the options and show a preview of the PCB. Most manufacturers allow you to order a small number of prototypes at a reduced cost.

gallium2.zip
A 6x4" (15x10cm) single sided PCB designed to fit into a picture frame. It has a USB powered 6x9 grid of LEDs, each with its own resistor.
I would suggest 220 ohm resistors and 5mm diffused flashing LEDs, but a random mix of static colours or slow RGB looks good too.
The PCB can accommodate either 1206 sized surface mount resistors or quarter watt through hole resistors.


A4gallium.zip
An A4 single sided PCB designed to fit into a picture frame. It has a USB powered 13x18 grid of LEDs, each with its own resistor.
I would suggest 470 ohm resistors and 5mm diffused flashing LEDs, but a random mix of static colours or slow RGB looks good too.
The PCB can accommodate either 1206 sized surface mount resistors or quarter watt through hole resistors.
This PCB has 938 solder joints on it, so is quite time consuming to build.


usbpir.zip
This is a very handy module. It lets you use a USB wall plug or power bank to run a string of decorative LEDs that only light when people are around.
It requires the type of power bank that puts out 5V all the time, as "smart" power banks will go into standby if they don't detect a load.
A PIR module has such low standby current it will run the lights for a very long time on a power bank.
The radar modules have a higher standby current but will still run for a long time on a power bank between charges.
The USB connector is a through hole 2-pin type that is mounted surface mount style on the track side of the PCB.
The YouTube video for this project.


sploosh4.zip
This PCB operates at full mains voltage. This project is only for those experienced in working with wall power.
When retrofitted to an "airship" LED disco light, this PCB converts it from being a pulsing flashing light into a simple pattern projector.
An image of an 8x8 array of LEDs is projected onto a wall like stained glass. The PCB uses clear focussed 5mm LEDs
The PCB replaces all the existing circuitry including the PSU, fan, controller and original array.
By using two capacitive droppers the PCB can be used on 110V to 250V.
The YouTube video for this project.


5x7sign.zip
A PCB for making a 5 x 7 LED character for fixed message signs.
It may be a LOT cheaper to get standard green PCBs and spray paint them if you want black panels.
The PCB can accommodate 3mm, 5mm, 8mm, 10mm, 12mm and single colour superflux LEDs.
Each LED has its own resistor, allowing colours and styles to be mixed.
Each module can run from between 3V to 5V allowing battery or USB power.
Choose the resistors based on voltage and LED type. On 5V a typical value could be 150ohm or higher.
Assembly guide for this project.


3x7sign.zip
The 3 x 7 version of the above sign PCB for slimmer characters like 1, I, -, : etc.



PCB LAYOUT FILES



PCB viewing and printing software.
The link to the Abacom website for the demo software that can be used to view and print these files.


Test PCB grid (testgrid.lay).
This 6" by 4" test grid PCB layout will let you calibrate your printer if needed. It's also a useful 1/10" grid.


Tupper-light PCB layout (tupper.lay).
Tupper-light PCB file for a small LED feature light that uses a protected lithium cell for power.


Large Nixie-flower lamp PCB layout (nixilamp.lay).
Nixie-flower PCB file with markings for components and neons. All neons must be from same batch.

5 by 7 pixel sign PCB layout. (sign5x7.lay).
5X7 dot matrix LED array PCB for building low voltage fixed message signs.
Assembly guide for this project.


3 by 7 pixel sign PCB layout for narrow characters. (sign3x7.lay).
3X7 dot matrix LED array PCB for building low voltage fixed message signs.
Assembly guide for this project.


5mm LED floodlight retrofit PCB layout (flat5mm.lay).
28 x 5mm LED version of the PCB for retrofitting into the very low profile LED floodlight cases. This is the preferred version, since it allows the use of more LEDs and is therefore brighter.
The YouTube video for this project.


Multi-LED format floodlight retrofit PCB layout (flatflood.lay).
15 x multi-LED version of the PCB for retrofitting into the very low profile LED floodlight cases. Note that many of the red superflux LEDs on ebay have incorrect polarity marking, so double check polarity if using red superflux LEDs.
The YouTube video for this project.


LED snowdrop ornament PCB. (snodropz.lay).
A project I originally intended to put on my website. It's an LED ornament based on a snowdrop flower with green LEDs at the base and six stems each with a drooping white LED at the end. Suggested resistor values are 220 ohms for all positions on a 12V supply.
The YouTube video for this project.


USB powered LED bonsai tree PCB. (bonsai2017.lay).
A PCB that lets you build a small and surprisingly good LED bonsai tree that runs on 5V, so ideal for a USB power supply.
Suggested resistor value for all positions is 220 ohm quarter watt. Almost any standard LED can be used.

Mini heat/light board for crystal lamp. (crystalusb.lay).
A 2" diameter PCB that is designed to be USB powered and provides heat for movement and light for sparkle in the low voltage version of the Gillian's diamonds lamp.
