What: Build up some optical mouse sensor boards using the ADNS-2620 sensor described in this previous blog entry.
This will involve some hot-plate reflow soldering using stencils and solder paste, some through-hole soldering, and testing.
There are only 9 surface mount parts and 3 through-hole parts, so this is a relatively simple build.
When: During the normal March PARTS meeting (3/3/2012)
Meeting starts at 10:30am; we’ll probably start building at 11 or 11:30am after a short presentation and show-n-tell
Who: You! But, we’re limited to only 12 boards + a couple extra. First come first serve.
- A small desk lamp is very helpful
- Magnification is very helpful (the smallest parts are 0603)
- We could use a couple more soldering iron stations, power cords, and power strips
- An Ardunio, if you have one, for testing out your sensor. We’ll have an Arduino or two set up for testing as well.
- A 4-pin 0.1″ jumper cable to connect the female 4-pin 0.1″ spaced square-pin header on the OptiMouse board to your Arduino

See you there!
There’s still a number of BrushBotComm boards that people want to build up, and at Saturday’s meeting we decided to try for a somewhat impromptu board build at this Monday’s (1/10) group project meeting. I realize this is short notice, but at the meeting enough people expressed interest to make it worthwhile. We can have another small build session later for those who can’t make it.
Scott’s bringing the hot-plate reflow system and I’m bringing the parts. You bring whatever parts you might have already gotten from me, some magnifying device if needed, a soldering iron (if you have one) and some cash if you haven’t paid for parts yet.
We’ll be at the bRainSilo:
See you there!
Not enough of the regulars can make it tonight so I’m going to cancel the BrainSilo build session.
Have a great Labor Day!
We’ve been getting together every other Monday night at the silo to work on group projects, but really what we want to see is more robots being built, be it by individuals or groups. So even if you’re not interested in the current swarm robot project, feel free to bring your own robot-to-be on down to share in the excitement of mashing together mechanical bits, hard bits, and soft bits to do cool stuff.
And if you DO have brushbots, bring them down and let’s get them talking!
Hope to see you there!
Pete, Tim, Scott and myself will be there. Will you? Bring your Brush Bot on down and let’s get them talking!
Last time Scott and I got four or five BrushBots running around in an arena with comm boards attached — one configured as a transmitter and the others as receivers. We only had simple RX and TX code running, but the receivers were picking up messages quite frequently; much better than we were expecting, actually.
But just five bots isn’t too exciting. It’s time to get a bigger swarm together and develop better message passing code! Bring your brushbots, bring your comm boards and let’s swarm!
While Scott and I hearded bots around, Tim got his steering control of the brushbots (a homemade toothbrush-head based bot in his case) working. The really cool thing is that he’s only using a single vibrating motor, yet still getting steerability! Come on Tim… Hurry up and upload the details on how you’re doing this!
Hope to see you all tonight,
Come on down Monday night and join in on the BrushBotComm activities. We’ll be continuing with the IR receiver transmitter protocol development and mounting the boards on to brush bots.
6/28, 7pm bRrainSilo
Hope to see you there!
The next group project meeting is Monday evening — same time, same place:
6/14, 7pm bRrainSilo
How many people want to build up some BrushBotComm boards using the Tiny84 at the meeting? (Tiny44’s are still out of stock)
If there’s enough interest, we’ll do it — please reply on the mailing list, or below, with the number of Tiny84 based boards you want to build.
For those with a board already, let’s start working on the Rx/Tx protocol now that we have the IR working, and figure out the best way to strap these boards onto the BrushBots!
See you all Monday!
