Super Bugbot

Super Bugbot

Comments 0 Comment

Components Used:
2 Motors
2 Touch Sensors

Required Parts:
RIS 1.0

Description:
In essence, this is Dave Baum’s BugBot, (No copyright infringement intended). I added an extra set of antennae (To be able to sense further up, so it wouldn’t get stuck under the bottom of a chair, counter, etc). I also made the speed faster in the program so it can run around the room a little more efficiently.

Instructions:
Building instructions for Bugbot are found on page 109 of Dave Baum’s Definitive Guide to Lego Mindstorms Robots

Canon EOS SLR Wired Shutter Release (Work in Progress)

Canon EOS SLR Wired Shutter Release (Work in Progress)

Comments 0 Comment

Ok, just starting out, but I’m going to make a shutter control as described here: “Super Mini Switch – A RS60-E3 Replacement”.

Parts I have so far:

From a broken Casio calculator:
2x Calculator Buttons (I’m trying to decide which ones, I’m thinking either C (red) or EXP (grey) for exposure, and ‘.’ (blue) for focus)
1x Rubber Layer with buttons to trigger touch sensor

From a broken CD Player:
1x 3.5mm Stereo Plug

From my cool junk pile:
1x Touch Sensor

From an old machine my dad got from work:
1x SPST Toggle Switch (Off/On)

From Dallas Semiconductor:
1x Plastic Box for shipping and storing ICs

It’s a shame what people throw away, really. I found the “Broken CD Player” smashed to pieces on the ground, ditto with the Casio calculator. Total cost so far: $0

Update: Stuff I got from the Dollar Store for the project:
Cell phone headset (for the 2.5mm plug) ($1)

Field Day 2006

Field Day 2006

Ok, so I went out to Field Day 2006 (Last full weekend in June) for Saturday evening, we didn’t have the stuff ready to camp out all night.

It was a fun day, including:

  • trying to find (dad’s) car keys in the grass for hours, to find them sitting in the lawnchair’s cupholder
  • getting lots of QSOs just as I sat down
  • an evening of mosquitos, chit-chat, QSOs

We finished the night by hitting a satellite repeater on my handy-talkie with Matthew, VA3MHB’s hand-held Yagi antenna. It was a team effort trying to hold everything together and point the yagi at the right spot, and although we didn’t make a contact, we did hear ourselves on the satellite downlink.
