Re: Electromagnetic interferences on Alpha/Arduino?

After several experiments, nothing could reduce the electric field, even turning off the wifi. I guess when you have a tiny piece packed with electronics that's to be expected... Another issue with the Alpharduino is that you cannot turn it off. While working on a project with many components I melt...

Re: Electromagnetic interferences on Alpha/Arduino?

Thanks, I only have smaller capacitors at hand (I'm stranded far from home), I will try for the sake of science and as a courtesy for your kind reply when I order capacitors for a project. But from what I see that fat capacitor with short leads would block both pairs... also the tingling I get from ...

Re: Electromagnetic interferences on Alpha/Arduino?

Thanks for your reply... can you elaborate? You mean right on the panda board, in parallel on a pair of 5V/Gnd sockets (attached picture)? I measured a constant 900V/m near the panda... I'm not sure how precise the meter is, but as a reference the high speed (fiber optic) wifi router antennas were b...

Re: Electromagnetic interferences on Alpha/Arduino?

Well I just ordered a new Arduino, I guess that kind of solves the problem and for just a few bucks :lol: ... I will use my alphapanda for what it does best, as a mini computer. I'm still curious though if anyone had the same issue or it's just me...

Electromagnetic interferences on Alpha/Arduino?

Hello, I recently started using the Arduino on board my alpha instead of my former Uno... but it's a bit messy... components are tingling even without power. so I read the digital pins randomly getting high for no reason (with no program and nothing attached except a cable). In a project involving l...
