Here's my question.
I'm a trained chef, I did alot of sous-vide cooking in restaurants and etc.
What I would like to know is, is it possible to create a home made Thermo Circulator?
Picture related, it's their old model (you can see more of the parts, I guess)
You can basically get the temperature of the water (normally in the 60C) for extended period of time, and the newer models have a way to move the water (fan?) so the heat gets distributed evenly.
How would I go about building a little machine for cheap? I really don't want to shell a 300$ for a cheap ass home version. Profesionnal version (the one I'm used at) is 900$

i'm trying to spoof the vod server of my satellite receiver
last year i had an old version of the set-top-box, it was using an HTTP connexion, i could spoof the server with a raspberry pi as a DNS and WEB server
on the new set-top-box, they are now using HTTPS (ssl) and forbidding to set a local DNS server
so i setup the raspberry pi as a gateway, and running a web server with SSL support, then routing address with iptables to redirect to the server
when i sniff the connexion, everything is running as expected, the set-tob-box makes a dns request, get the real ip of the webpage, then ask the page to the real server, the raspberry redirect the ask to my server
but, the set-top-box get an error, i guess it is from the unverified CA of the certificate (which is self-signed)
when i simulate on a browser, firefox gives a warning about self-signed and untrusted CA, but if i allow i can go further and make everything works as i wanted
so my question is : is there a way to make that work?
i tried to redirect the page to another server using a trusted certificate (google.com) but still get an error
i also tried to iptable the 443 to 80, but it still try to comunicate with SSL protocol, is there a way to make a clean protocol redirection? or i'll still need a trusted certificate?
and last question, as everything is offline, is there a hacked/leaked trusted certificate available to download?
i just want the stb to get only a spoofed page, i thought a man-in-the-middle attack would be working, but no
Antenna Design for Short Distances

I'm looking to build a small, short distance radio receiver.
Keep this in mind -- My piece of paper says I'm a chemist, and I have a hobbyists understanding of electronics. I have no background in communications.
What is the best way to go about making an antenna for such a radio? It needs to only be able to pick up a signal emitted within the range of my house. Maybe my city street. But I can't seem to find any appropriate tutorials for such a device.
I had the idea to etch a fractal antenna design to the back of a PCB, and couple it with a decent variable capacitor, but my understanding is that it is only useful for multiple bands within the high frequency ranges.
Keep in mind I haven't even looked at making my emitter yet, but I will likely be making that from scratch, as well. So, I need a small, pocket sized radio receiver, that will pick up in a band range that is relevant to hobbyist accessible signal emitter.

So my church's pastor has decided he wants to bring the church into the 21 century, and has asked for my help since I'm one of the most techie-minded people going there.
He wants to create video advertisements/dramatic stuff, as well as livestreaming and podcasting things. He said the church will be getting a Mac (Which I've never touched before) and a fancy video camera.
The situation is, I have experience in video editing and know my way around a PC, but I've never bothered with livestreaming or podcasting, never used a Mac, and the last video editing medium I used was Sony Vegas 9 a few years ago. And he asked me to get him a list of everything I'll need.
So... what all supplies will I need, other than a video editing program and a camera?
How difficult will it be for me to figure out livestreaming/podcasting and using a Mac?
Any advice in general?
