The cheapest and fastest way to get a circuit board made
A little while ago, a guy emailed me and said he wanted to practice his programming skills and therefore had made a site for comparing prices for circuit boards. I checked it out, and it was
Something everybody should know
I was sitting in the armchair in the living room and I was maybe 13-14 years old. It was something that me and my dad was talking about that got me thinking. I had heard somewhere that 1’s and 0’s was the foundation of computers, cell phones, TV’s, remote controls, digital watches… And I had […]
