Voltage step-down buck converter Testing with power, step-down converter in heat-shrink tube To power the Raspberry Pi 5V is needed as well, for that I used a step-down converter that I just put in a heat-shrink tube.

#RPI WIPEFS PORTABLE#

To make it portable I wanted to run the entire thing on a 12V battery. Putting it together Raspberry Pi Zero, with HAT, connected to stack lights for testing Terminal blocks, screw, PCB, 3.5mm, 2-pin, straight Terminal block, pluggable, 5 mm, 6-pin vertical male Straight pin header, female, Dual row, 2.54mm PCB, perfboard prototyping, 50x70mm, 35cm2 Schematic diagram Schematics for the Raspberry Pi output HAT Parts used (HAT)ĭarlington-driver, 7 step, ULN2003A, DIL16, In: 2.7K/5Vĭarlington-transistor, PNP, 5 A, 60V, TIP125, TO-220 I only need three outputs now, but having a few extra is always nice 😃 Raspberry Pi GPIO pinout Outputs It has five Darlington transistors and a Darlington driver. Since I’m no longer using my Alertmanager stack lights, I reused that HAT (Hardware Attached on Top).

#RPI WIPEFS INSTALL#

$ sudo apt-get install python3 python3-rpi.gpio I’ve written an article about getting the Pi ready, but here is a quick run-down: I first soldered on the headers for GPIO pins, flashed the SD card, and got the Raspberry Pi connected to the Wi-Fi. Like adding MQTT and communicating with other traffic signals.Īnd being able to SSH in makes it very easy to make adjustments to the software. Having the controller on Wi-Fi gives me a lot of options for future expansions. I decided to go with a Raspberry Pi Zero W. Traffic lights stand, all painted Raspberry Pi Painting done, now ready for the electronics. So the kids painted it grey 😃 Kids painting the traffic lights stand Kids painting the traffic lights stand And we had some grey left over, and I didn’t want to go to the store. I originally intended for it to be black, but I couldn’t find the black paint. The next day I also mounted a board on the backside, to have somewhere to attach the box for the electronics. Stand for the traffic lights, ready for painting On top I mounted a board at a slight angle - it just made it look nicer 😃 So this is what is looks like, before painting. I attached four rubber feet to make it less wobbly. Foot for the stand, mounted with angle brackets It can be disassembled simply by removing those two bolts, to take up less space when stored in the winter. The pole is secured with angle brackets, and two bolts to the foot. I made cut-outs in the lumber for the foot, so they could be placed to form a cross.

I mounted a small block of wood for the stack lights, and cut a groove to route the wires through. The stand is very basic, it’s just a 2×3' pole with a foot - also made by 2×3'. To control it I am using a Raspberry Pi Zero W, this will allow me to make it communicate on Wi-Fi and MQTT later. I first started with a traffic light, simple - red, yellow and green.

To make it more fun, both for them and me, I figured I’d build a series of traffic signals that they could play with. Please be careful when doing this. Any error or mistakes can damage your data on the disk forever.As the weather is warming up here in Norway - my kids have gotten their bikes out. Now we can start create new partition and filesystem to the USB disk. There is no more partitions found on the device which means all the partitions and signature information have been erased.

dev/sdb: calling ioclt to re-read partition table: Success dev/sdb: 2 bytes were erased at offset 0x000001fe (dos): 55 aa If it success, it should show something like sudo wipefs -a /dev/sdb I will wipe the /dev/sdb (my usb disk) using wipefs commandįirst, make sure there is no mounted partition on the USB disk.
