RPi + Arduino USB Security Camera

Hi, I'm planning to create an offline Home Security Camera which has its own controller for turning it on / off. It would record images and/or video from a USB webcam to an external HDD or a USB stick when it detects movement. Idea is that when I leave the house, I can just turn it on in the lobby a...

Re: Mid-altitude Pi-balloon

I don't think you need to over do the insulation. If the Pi/batteries/camera are exposed to sun in a thin transparent bag you might have problems with overheating not excessive cold. Even at ground level you can raise temperature 30 centigrade above ambient in a simple transparent bag. With increas...

Re: Mid-altitude Pi-balloon

I actually made a small lift calculation error in this. A jumbo latex balloon itself weights about 45g. A fully inflated balloon takes about 424 liters of helium, which can lift 455g of weight. With the weight of one balloon, that's 410g payload and with two balloons that's down to 365g. The compani...

Re: Mid-altitude Pi-balloon

You might not want a Pi to monitor the GPS, but a more power efficient arduino that will save you a lot in battery weight. The only reason I would pick a Pi zero instead is to use it with its small, light native camera and leave the 125g canon down. That should cut your payload weight in half Hmm, ...

Mid-altitude Pi-balloon

Hi, I have an old Canon Ixus camera which still functions. I had the idea of sending that out into the air with a helium balloon, along with a GPS tracker, so that I can retrieve the images it takes along the way. I believe the Pi could do that GPS transmission for me, with a GSM module. The basics ...

I think it will work. What does your adapter look like?
It's a small USB-C to microUSB adapter, similar to what you get with USB-C phones, except the port adaptation is from USB-C female to microUSB male.

RPi4 PSU with older models

Hi, Most sellers advice not to use the official RPi4 power supply with older Raspberry models. While I understand that they use a different plug, is there really any good reason why not to use it, if you have one of those tiny USB-C - microUSB adapters? For some reason the RPi4 PSU is much cheaper i...

Re: 1.5A power for Pi 1 B+ NAS setup

Okay, perhaps time to invest in a proper power supply then. However, I'm trying to keep the overall cost down and a powered hub in my parts of the world cost almost as much as a new Pi 4. The SSHD will be the only device attached to the Pi (plus the Ethernet cable) so I'm just wondering what would ...

Re: 1.5A power for Pi 1 B+ NAS setup

If you refer back to your other thread, you'll realise that an early 1B won't be able to power that dirve when idle, let alone when writing or spinning up. A later 1B can provide 600mA. Enough for it to idle but not enough for anything else. A powered USB hub or some otherway to inject power to the...

1.5A power for Pi 1 B+ NAS setup

Hi, I'm planning to setup a Pi 1 B+ as a NAS, where it would only be connected to a 1TB 2.5" SSHD (hybrid SSD+HDD) and an Ethernet cable, nothing else. The Pi 1 B+ uses approximately 330-340mA. The SSHD (old ST1000LM014) uses 180mA when idle or 620mA when reading/writing. However, it can require a m...

Re: Raspberry Pi 1 as NAS?

My first try for a "purpose built" RPi based NAS was a RPi1B+ with a 2TB HDD ( I was gunning for [1 x 1TB] + [1 x 2TB] ) but didn't go as planned. it was a microSD boot (bootcode.bin method) + HDD root setup. booting the system as a 2-HDD system was like "hand-crank starting a car engine" wherein I...

Re: Raspberry Pi 1 as NAS?

For the power-off functionality, I suppose I could simply tuck the whole thing in a corner and use my phone on the same network to send the shutdown command. If the Pi automatically starts as soon as power is applied, how does it work in reality when I've sent a shutdown command remotely; when does...

Re: Raspberry Pi 1 as NAS?

No Pi is going to power more than one 2.5" HDD. The maximum current available to USB devices is 1.2A, one HDD can draw that much when spinning up. A "Y" cable won't help as the Pi doesn't do per port current limiting. The best PSU to use is the official one. One with a higher current rating will be...
