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.
minion.zip
A small Chizhevsky ioniser PCB designed to fit into a Hammond 1591XXATBU case (100mm x 51mm x 25mm) or (4" x 2" x 1").
It uses 22 10nf-100nf 630V capacitors, 22 1N4007 diodes, 2 1-Megohm or 10-Megohm one-watt resistors, a 330K quarter watt resistor and a neon indicator, to create a high enough voltage to ionise air at needle or carbon fibre tips.
Note that this circuit is ONLY SUITABLE FOR 220V to 250V AC POWER. It will not work properly on 120V.
The YouTube video for this project.
gallium2.zip
A 6x4" (15x10cm) single sided supercomputer 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 supercomputer 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.

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.
USBdangle.zip gerber PCB files
dangleUSBbase.stl Case base STL file
dangleUSBtop.stl Case top STL file
This PCB is for an ornament with up to 20 LED scokets on tendrils that fan out from a base with a micro USB connector.
This project also includes STL files for an optional two part case.

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.

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.

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.
