Garage Parking Lights Translation to Arduino

I really liked the Nuts & Volts Magazine project “Garage Parking Assistant” in January 2010, but I don’t ‘do’ Basic Stamp – no reason really, just not my favored platform and N&V seems to base a lot of projects on that platform.

So, I translated it to Arduino and replaced the Basic Stamp with a minimalist Arduino (Atmega 168, a clock resonator, a couple of resistors and capacitors, and an LM7805 voltage regulator). From there, code translation (BASIC to  “C++”) was easy. I’ve written up a project listing and I make no originality claims and I’ve only provided a code translation.

Yet another Part 15, AM Transmitter

Yet another Part 15, AM Transmitter A Two-Tube AM Broacaster – 6GY6 Version.

Very fun to build and this one is turning out to have the best transmitted audio so far.

Updated: Revisited the original 6888 version which has already been updated with a 6AB4 pre-amp, shielded all the signal paths (audio and crystal oscillator) with RG-174 coax, and replaced the Tank (Antenna Coil) with the PI Output.

Tragedy Strikes!

My 25-year-old Weller WTCP gave out.

I was repairing one of the two Astron RS-50A power supplies I picked up recently and when I swapped the tips to get more heat out to the massive transformer center-tap… nothing. No clicking. The neon light was on, but no heat was home. It was a terrible discovery.

I’d had that old iron since Mostek. I think I bought it at some employee discount. Lots of projects from the old days and from recently were completed with that good ol’ tool.

So, my choices were to buy a replacement soldering pencil from Fry’s for $69.99, or just get a new one; the WES51 is not much more and is ESD and has a variable heat control. So I sprung for the new iron. But now: what to do – part out my old friend? Can’t let that 2A transformer go to waste. But I can’t hack apart an old friend. Aw, heck, went right back to Fry’s and snagged a TC-201A pencil to go with it. Now it’s the garage soldering iron. I think we have soldering covered here at the house.
