Same duty cycle but with a faster pulse rate and some NaCl on the breakout (1/10 second exposure)

ALL images were timelasps with 6" shutter speed. This way, I sat back, relaxed, as the camera did all the work. This was the first time I ever took a camera with me so cheesey

Start of the finally - Too much rain and roman candles!!!
ThTh

The finally consisted of what i call "rain" and roman candles (Very loud BOOM) and they launched over 50 in a row with less than 0.5 second delay, holy crap! I had over 100 pictures but I picked the best outlooks.

That's a nice find c4r0! Wish it was that easy to find stuff lying in the streets around here, they're almost clean.

Th

Yesterday I decided to etch my first ever PCB board. It only took 10 minutes using radioshacks etch solution in an agitator. I then noticed I had 2 flaws on the board, 2 holes were touching each other..(hint one is on the 555 pins in middle) So I used a fine-point dimond dremel tool, fixed it :) This is just a GENERAL 555 board. No mosfets were ment to be attended. Just a general "for anything" 555.

I think the issue was too much toner actually, Some of my holes as you can see are not even. I think it's due to using too much toner, but I was still impressed how fricken easy this was. All I had to do was print gloss photo paper, Iron on linen, peal paper off, use dremel nylon brush tool, etch, done. No re-makes. I printed it on "Hard grit" paper (9 year old printer)
