1) Components:
For my first DIY enclosure I used a big power supply similar to 3d printers power supply. For this project I decided to use an 12V 5A AC adapter from Amazon for 12$:
In order to plug the Raspberry, we need to supply 5V and I choose a JZK power module with USB plug:
2) Wiring:
With this components no soldering, no more cable, it is ready to plug !
Raspberry PI start perfectly without any plug or connection problem.
3) Light component:
I choose 5050 led strip pasted on cheap plastic profile.
3 sides of the enclosure will be lighted.
Total 84 x 5050 leds = 16.8 Watt = 1.4A (12V)
With this configuration I get approximately 1400 Lumens, That is good enough for lightening an enclosure.
On this configuration, led strip will be on top of the enclosure, on left, right and front side.
There is also led strip with higher density of led, therefor it is possible to add light only on 2 sides of the enclosure.
4) Light wiring:
I used the free 12V connector on JZK power bulk to connect the wire with a On/Off “Rocker Switch” from ebay.
For testing, I add a small mini DC voltmeter (from ebay also) to check USB voltage.
Soldering was easy to do on led strip.
It is also possible to use a relay board to control light with Octoprint. There is a nice plugin to do that : Enclosure plugin.
5) Testing lights:
I make a small video to show you led strip brightness.
You can see also that USB voltage stay stable when I switch on/off lights.
Next step?
I would like design a stand alone case for the JZK module. I would like also design led strip support in order to don’t need to buy plastic profile.
To be continued..
It was an easy and quick project to do a stable power supply for the Raspberry PI.
Adding lights cost was also very limited: below $5 !!!
Feel free to send us all your suggestions.
Look forward to seeing more of this type of blog. Very useful. Well done.
Thanks Colin !
The connection you used for powering the LEDs, I thought it was input only can it do both or did you reconfigure?
Hi Daniel,
Good question ! I did nothing and it works !
That’s fantastic, I’ve been looking for a build like this. Thanks. Look forward to more projects.
One question, which i think you have started to comment about… Where can the JZK module (and light switch) go? I am also thinking this module can power a 12v fan for the hepa filter, so this would make a second switch requirement. Also, why not add a temp & humidity sensor to the new unit. This makes a larger unit with many useful controls. The only problem is location of the unit.
Designing a case for all these items isnt a problem, but locating it, and allowing a cable route through the casing, may be a problem. Would be interested to hear ideas.
Hello Colin,
JZK module is located close to power supply with light switch.
It will be connected to filter fan. I use a PWM rotating switch for fan 0/1/speed.
I plan also to use a temp sensor with octoprint-enclosure plugin to control fan speed with PWM mosfet.
Bonjour
Pour le raspberry, est il prévu de mettre un autre modèle comme un 3 ou 4 et pour l’écran idem comme un hyper pixel 3.5, car j’ai déjà des raspberry et des écrans en 5 et 3,5 et c’est généralement ces modèles là que nous utilisons pour octoprint et non le raspberry PI car c’est ce modèle que vous citer ou j’ai pas bien compris.
D’autre part j’ai commendé hier soir votre box mais je viens de m’apercevoir qu’il n’y avait aucun détail du contenu du kit et également des étapes consultables mais pas entièrement (juste la une visiblement ) et d’options !! Elles seront payantes ? Ou gratuites ? Indispensable pour que la box soit fonctionnelle ?
Désolé mais vous nous présentez votre box entièrement finie avec tout complètement attrayant et je me demande si ma commande comprendra tout ou qu’une partie du visuel comme nous n’avons pas de détail du kit
Désolé pour toutes ces questions mais elles me semblent utiles
Merci
Merci de ne pas tenir compte de ma question sur les raspberry j’ai eu la réponse comme quoi il vaut mieux attendre d’être réveillé avant d’écrire 😀
