 +===== Maker Faire =====
 +Really fun, especially for kids. Great opportunity for networking and learning from experts about what they do.
 +==== 2019 ====
 +Tinker Camp, kids were quickly making cool stuff with just cardboard, scissors, and tape and loving it. They have adult sessions as well. 2nd wednesday of the month, 6-9 pm, doing hands on tenacious stuff around a story. Would be worth checking out once!
 +Oregon Amateur radio society, wrote down the stuff elsewhere.
 +PDX Hackerspace,​ they even have a building! $40 a month, no problem if unemployed. 24/7 access.
 +===== Doorknobs =====
 +Frequently used doorknob (garage door) has stopped slamming shut. You can tell your manufacturer by looking at the latch. Schlage has no questions asked lifetime warranty on mechanical parts: https://​​a/​11948
 +Georgian Aged Bronze Keyed Entry Door Knob: https://​​p/​Schlage-Georgian-Aged-Bronze-Keyed-Entry-Door-Knob-F51A-GEO-716/​204834188
 +CAS 1705162
 +F51 (new keyed latch)
 +CAS 1749141 is new number
 +===== Small Fixes =====
 +Some things that have helped me fix things and keep them working:
 +  * Shoe Goo for shoes and other things. Doesn'​t dry out in the container like rubber cement or silicone
 +  * If you're getting unreliable power especially when shaken on AA/AAA powered devices, check the battery terminals. The negative (spring/​pushing) end tends to compress over time. Pulling on it and stretching it out again restores the tension on both terminals.
 +  * 
 ===== Intel Beneplace ===== ===== Intel Beneplace =====
 Columbia employee store, can get access through Beneplace. However, don't feel confident the quality is 2X better than Amazon.

-===== FIRST Robotics Activity ===== 
-==== Engineering Passport @ Houston ==== 
-  * What were the most cool/​innovative uses of programming that you saw at different teams' booths? 
-  * Sometimes there are multiple ways to solve a problem a team faces. Are there any strengths of programming over other methods? Weaknesses? 
-    * One example is our own robot. We needed the strength of multiple motors to flip our robot up onto the HAB, but needed the motors to work together in sync. A mechanical perspective would be to use a steel axle to prevent one motor from turning faster than the other, whereas a programming perspective would be to use encoders and measure the difference in rotation and correct the commanded speed "in software"​. 
-    * Modern systems often combine the learnings of several disciplines to get a superior solution. Did you see any examples of this? 
-      * Bonus Question: Interestingly,​ we were able to combine both mechanical and programming solutions on our robot, but the steel axle used visibly "​churro-ed"​ after a few opening matches at PNW championships. Why might this have happened?

-==== Hands-On Orientation Activity ==== 
-I want to ask the kids, see what they would like to do. Most things they think of are pretty cheap, I think. 
-=== LED strip on X === 
-  * Can use basic design from helmet led strip to put in other places like bicycle or ... gaming computer/​console?​ Kinda spendy at $7/meter, but seems pretty popular. 
-=== Nametag === 
-Really depends on what we want to do... 
-  * $3-4? Cheap and hands-on option is etched plexiglass with top or side led lighting. Can probably power led with aa battery or 3v lithium battery. 
-    * Downside is no customization or animation 
-  * $3 arduino + $5 oled watch display + 3.3v or 5v baterry.... https://​​MakerFocus-Display-SSD1306-3-3V-5V-Arduino/​dp/​B0761LV1SD/​ref=sr_1_3?​keywords=oled+display+i2c&​qid=1554692347&​s=gateway&​sr=8-3 
-  * $15 LED display. Maybe you can send new icons down, but maybe not.

-  * $15 OLED + arduino + lipo charging (add $5 for battery?) + wifi https://​​ESP8266-development-Arduino-NodeMcu-0-91inch/​dp/​B074373KTY 
-{{:​home:​pasted:​20190407-193830.png?​300}} ​ 
-  * $20 somewhat light android phone that's normally $50. These are incredibly feature filled and versatile for the price. It's quite silly.
