You might be a geeky dad if: your kids practice spelling in Morse code

Kids learn better if they’re engaged in the topic at hand. [Todd] found something that has his son just begging to practice his spelling words each night. He converts them all to Morse code and taps each out on the Morse code practice station they built together. To start off Todd connected the keyer to his Fluke 87 meter, using the continuity tester to sound a beep each time the key is depressed. But this is just a temporary setup until [Todd] could help guide his young one through some circuit design and assembly.

The replacement is based on a 555 timer. They grabbed an electronics project book and found the schematic along with a Morse code primer. With parts in hand [Todd] films as his son hones his soldering skills with each connection. The finished project uses the timer chip to produce the audio frequency heard from the on-board speaker. If you’ve never had the joy of teaching a kid how to solder, you’re going to love seeing the video.

Homebrew solder pot is too dangerous even for us

[rue_mohr] is building a hexapod robot, and that meant he needed to tin a whole bunch of ribbon cables with solder. Using a soldering iron for this task would take far too long, so he built a homebrew solder pot to tin all those wires quickly. While [rue] was able to get solder on all those wires quickly, we need to question his method – he used a halogen light and reflector to melt all that solder.

The build began with a recycled halogen light fixture. After taking apart the entire assembly, [rue] reassembled it into something resembling a solder pot; a concave reflector and halogen light bulb sit perfectly flat on the table, ready to accept pieces of solder.

After throwing the switch and putting a few bits of solder in the reflector, the solder pot surprisingly worked. [rue] was able to quickly tin his ribbon cables, and the halogen bulb and reflector didn’t break yet.

This is one of the least safe solder pots we’ve ever seen – the bulb could easily explode, and melted solder could come pouring out of the reflector at any time. [rue] is aware of the safety implications and make sure to wear a pair of goggles. If it works though, we really can’t complain.

Check out the video of [rue]’s solder pot (with an awesome temperature indicator light right in the middle of a pool of solder) in action after the break.
