SyberSlam #1 - Entry level robot fighting

The Enigmatic Electronics club has started a Robot Fighting League called SyberSlam!

Below is the introduction video to SyberSlam. Here we talk about the platform everyone

is starting with and what we are trying to accomplish. The base for our robots were

bought from Wal*Mart for $10.  Here is where they can be bought on Amazon for just a little more.
We got the idea to do this from a YouTuber we follow named GravityRoad. She had posted
a video of her at a competition called HeboCon and you can view that video here.

Here is what the SyberSlam Trophy is starting to look like

Here is the build progress video of some of the combatants.

Here is another build progress video of Steele machining some parts for mounting better wheels

Dumpster Diving - Episode 4 - Plasma Cutter

This week on Dumpster Diving with Enigmatic Electronics we dismantle a Plasma Cutter

We'd love to hear from some of you if you know what some of these components are.

We are hoping maybe some of these parts will be useful in a Tesla Coil project we are planning.

Please leave us a comment here or on our youtube video if you have any information on these parts.

Could this circuit be some kind of tank\oscillator circuit?

This looks like some kind of transformer...

 This board has some nice components to salvage for future projects

Check out the size of those capacitors!

An Enigmatic Electronics Build - Power Supply from Junk

This week on Enigmatic Electronics we show off the power supply we built from junk parts.

Here's a scan of the diagram

All That and a Bag of Chips - The Knight Rider Circuit

Building the Ultimate Knight Rider Circuit 

I've been working a lot with 555 ICs since I got into electronics about 6 months ago

I messed around with just about every circuit on This Website (www.555-timer-circuits.com)

I especially enjoyed the Knight Rider Circuit they have on that website, but I felt like it

could be better. So I started researching the 4017 IC trying to figure out what else it could do.

Then I came across a post on All About Circuits. I bookmarked the png schematic,

but unfortunately I didn't bookmark the forum post so I'm not totally sure who to give credit

to for this schematic:

This schematic did two things for the Knight Rider Circuit, it added more LEDs and

it added a fade off effect.  Now, here is the schematic I designed and built:

This circuit is not limited to just 9 LEDs, adding multiple 4017 ICs allows

for many possibilities. I've been getting into the Arduino stuff too, so I know

there are other options for this circuit.  I just find the IC chips a little more interesting.
