We’re so happy to have made it to the cover of Baltimore Sun newspaper. Grab yourself a print copy today, or check out the online edition here.
We are so proud of his accomplishment. If you haven’t read the article, click here. This is just the beginning of the press he has gotten lately. Way to go Mark! After so many years finally getting the press you deserve!
Thanks everyone who participated in the event. Our booth was a huge success. If you didn’t make it, view the entire article to see a picture flood of what you missed.
To name a few thing’s you missed:
- Mark’s biped robot HEX
- Eric’s telepresence robot
- Jeff’s LaserShark/Laser Pong
- The robot head game
- The cornstarch monster
- Paul’s chiptunes streamer/midi interface
- Miles and his cardboard robots
- An awesome vacuum tube amplifier
- … and the larger part of our redbull creation project!
See you next year!
You must register for this class on Meetup; Limited seating available.

You will learn:
How to use a breadboard
What capacitors are
How to use capacitors for filtering power
How to use capacitors for basic debounce/timing circuits
Connect a 555 timer circuit for blinking an LED
This will require the purchase of a breadboard and some more expensive parts that last time (I’m thinking it will be about $15 — I may need to adjust this after I buy the parts). I will bulk-order and get everyone more parts that you need.
700pt breadboard (Like this: )
A few voltage regulators (LM317, 7805) in TO-220 packages
A few 555 timers (DIP-8)
A couple potentiometers (5k, 10k, linear taper)
More resistors (assortment)
Some capacitors (.1uF, 1uF, 10uF)
I’ll update this as I develop the slides.
You will need to bring:
1 power supply – can be a wall transformer that is between 9 and 15 VDC and greater than 200mA output. You should be able to salvage on of these from any number of places.
22ga Solid Core wire (for connecting to you breadboard)
Some kind of wire cutters. I got some of these the other day:
(Small version – will handle anything that can fit on a breadboard)
Some kind of wire strippers. I like these but any kind that can strip 22ga solid wire is fine.
The parts kit from the last class (need the resistors, LEDs, and multimeter from it) or you can buy a kit for $5 (we may not have more multimeters available if you wait too long)
Either $15 or all of the parts that I listed in the parts section above.
Chris Cockrum will be hosting another class. This time is for beginning electronics.
There is limited seating available so Please register if you wish to attend. Wed, March 20th.
Part 1. Ohm’s law and Watt’s law
This class will teach the basics of voltage, current, and power. A lab will be included that will demonstrate how to calculate the proper value of resistor to connect LEDs to power.
Parts and equipment may be borrowed from the hackerspace or you can purchase a multimeter (http://www.harborfreight.com/7-function-digital-multimeter-92020.html), a few LEDs, a few resistors, clip leads, and a 9V battery for $5. Alternatively, you can bring your own.
