![]() ![]() Some guys have hacked Canon PowerShot cameras giving more features and a remote trigger through the USB port which can be triggered by a switch (or relay or maybe a digital output). If one of the RPi cameras is good enough it may be easier to do the whole thing with a Raspberry PI. The camera will be next hardest, in my opinion. If not investigate and try the PID library. A simple PWM and direction should be all it needs.ĭepending on your system and requirements a dumb On-Off system (like a thermostat) may be good enough to control temperature. Make sure it's rated for the voltage and current you need to deliver, but it should be easier to control than a motor. A motor H-Bridge will give you "bi-directional" control. The Peltier element will require a power driver. Calculating heat flux to properly size the element would require me to do a lot of investigation and learning, or I would just get one and experiment. I've never worked with peltier elements, but they sure are cool. When I look at this project I think the thermal design will be the most difficult. If it is plausible, I'd like to know which hardware that should be able to do the job. As I am personally more of a software-guy who have never played with Arduino before (although I do have experience with Raspberry Pi's), I'd like to know if there is a plausible way to build such a system with Arduino modules. This is the very basic idea of the system. Take a picture inside the box every minute and save the images to storage." If the lamps needs to be manually switched on when the program sequence starts - that is fine.īasically, I want to give the system the following instructions: They just need to be turned on while the program runs. The box should be equipped with light, It is however not necessary for the lamps to be controlled by the systems. I would need a thermometer that continuously reads the temperature in the box and reports it back to the program, so that i can keep a constant temperature. It is very important that the camera can take pictures with good quality in terms of color saturation etc. It is important that i can control white balance and exposure. The camera unit needs to be on the higher end of the quality spectrum. ![]() (This project inspired the idea: Peltier Cooling and Heating with Arduino – Tinkerer)Įither way, the temperature need to be programmatically altered from the arduino unit. By alternating the direction of the current, this should allow me to both increase and decrease the temperature in the box. Some form "heating block" which temperature could be regulated up to 60☌ (140☏)Ī Peltier element attached to a heatsink and a fan. The box needs to be about 50cm³ (~20 inches³)įor the temperature source, I have two potential ideas. The idea is to study how objects confined in the box are effected by being exposed to different temperatures during a long period of time (many hours). I am planning a project which goal is to create a kind of heated box (possibly also cooled as alternative) which content is monitored by a camera. ![]()
