Taken with a Pentax MX, Pentax 50mm f/1.7 lens with Fuji Xtra 400 consumer film.
Soldered 10 pull-up resistors of 22kΩ and 2 pull-downs, on the bidirectional lines.
Also shown, a 1kΩ jumper used for safely shorting inputs to GND or Vcc for testing.
Turns out the pullups are really redundant as I forgot you can just enable internal pullups on Arduino.
I took several photos of the Tamiya Twin-Motor Gearbox for a review I wrote a couple years ago, this is a photo that wasn't used.
Peeling out a strip of the (amazingly sticky!) backing makes it easier to remove the row of connector spring material.
The new color for the DorkbotPDX PCB Order.
Thanks to everyone that's suffered through my attempts to get the color right over the last few orders!
Mixing electronics theory and knowledge of correct usage of electronic components, with their creative application
a close-up of the Cr-48 keyboard. a bit dusty, sorry, didn't feel like cloning it all out. read my initial thoughts on Chrome OS and the Cr-48 on my blog
세계적인 그래피티 아티스트 존원(JonOne)이 3일(현지시각) 독일 베를린에서 열리고 있는 유럽 최대 가전전시회 IFA 2016에서 LG전자 부스를 찾았다.
LG전자는 이번 전시회에서 존원의 그래피티(Graffiti) 작품으로 독창적인 디자인을 강조한 존원 아트시리즈를 공개했다. 포터블 스피커, 그램 15 노트북, 21:9 울트라와이드 모니터 등으로 구성된 존원 시리즈는 제품 외관에 존원의 그래피티 작품을 적용해 관람객들의 이목을 끌었다. 존원이 LG전자 부스에 전시된 존원 아트시리즈를 소개하고 있다.
This image is the 2 outer layers of a 4 layer PCB I recently designed. This PCB is for my Logic Analyzer project - which if you're interested you can follow along at github.com/sgstair/logicanalyzer
Circuit board from a dead VTech cordless phone. Strange metallic colour due to the camera making weird decisions about the exposure.
The small wonder. A device that is just bigger than your watch, controls the security of your car, deploying sophisticated cryptography, RF technology and innumerable small principles of physics.
Since I worked in crypto for long, and studied RF, I understand amazing amount of transistors (millions) are working in unison to make this simple idea work.

Anti - Form Sora's glowy eyes before they're sewn into the mask. The actual eyes are laminated Electroluminescent sheeting, the little black box is a DC-AC converter, and a 9v battery goes at the end.

■ ‘그램 15’ 초경량 무게 소개하는 페이퍼 아트 영상 공개
□ ‘그램 15’와 종이로 만든 ‘페이퍼 그램’의 무게는 비슷
■ ‘내가 만드는 그램’ 이벤트 실시
□ ‘그램 15’, ‘21:9 울트라와이드 모니터’, ‘롤리 키보드’ 등 푸짐한 경품 증정
■ 한국HE마케팅FD 담당 허재철 상무 “‘그램 15’가 가볍다는 것을 소비자들이 쉽게 이해할 수 있도록 영상을 제작했다”며 “그램만의 혁신적인 가치를 적극 알려 노트북 시장에서 돌풍을 이어갈 것”이라고 강조

It's also an instructable so you can get the instructions here: www.instructables.com/id/MemAxe-8Bit-sound-effects-memory...
MemAxe is an electronic game that tests your memory by making you copy a sequence of sounds using switches. The sounds emulate those of old 8-bit game consoles.
Pretty damn crude, but at least I know that the servo can lift that motor, I still need to hook it all up so it is under control of one circuitry (right now motor and servo are separate) so I can make it mimic the actions of one of the servos in my software simulation.
I'm still figuring out this whole electricity thing, I gotta make sure my circuit can actually power all the servos and motors at the same time.
