The Beginning When this project started I was moving apartments about every year, so the only firm requirement was that I could fit the server in a traveling rack. Travel racks are most often used for smaller audio gear, not large server equipment,...
Today we present the FlameWheel Robot assembly tutorial and quick-start guide! It is rather difficult to assemble this robot without guidance. Feel free to refer to my introductory tutorial today.Flamewheel (A 2WD Remote Control Robot) is part of our...
The principle of operation: Person approaches to the intercom Looks at the camera The system compare his face with authorized people If it finds it, then the door opens and a person can enter There is also another way to pass; The person with the pass...
IOT stands for Internet of Things and refers to small devices equipped with direct internet connectivity, without needing an external computer. They are usually composed of a main microcontroller and an additional connectivity (eg. ESP8266 for Wifi,...
Problem Statement The Metabolizer is sort of like an ecological Rube Goldberg machine- it's a chain reaction-type system intentionally designed to perform a simple task in an overly complicated way. In this case, the simple task is "not throwing...
When I decided to release Sawppy to the world, I thought briefly about how to best organize all the information I want to convey for rover assembly. I quickly fell into a state of Analysis Paralysis and, as a path out of that state, decided that it was...
(Originally published here.) The Cisco HWIC-3G-CDMA PCB After the abandoned attempt (*) to reverse engineer the $5 Cisco VWIC2-2MFT-T1/E1 card (because its Stratix II FPGA is not supported by Quartus Web Edition), I set my sights on another...
A year ago I picked up some new-old-stock "VQB 71" 7-segment displays — not for any particular project, but simply because they looked fantastic. These gorgeous, vintage common-anode digits have distinctive segments with six tiny LEDs each, internally...
Whenever I design a board, I optimize as much as possible. Layer count, part count and even part location can play a big role in how much assemblies cost later down the road. In this article, I go into depth about the decisions I made when designing...
Summary Just exploring some Docker basics, with a bent towards Raspberry Pi when relevant. Deets The path to here is long and tortuous. Multics. Unix. VAX. 386. V86 mode. chroot. Solaris Zones. cgroups. LXC. and now, Docker. The concept is similar...
Sunday, 18/06/2023, 18:25 Soooo... I don't even know why I'm writting this project log, I really don't think that I will have the money, nor the mental fortitude and determination to go through with this project, but for some reason, I keep going forward....
The high-performance, low-power Microchip 8-bit AVR® RISC-based microcontroller combines 8 KB ISP Flash memory, 512B EEPROM, 512B SRAM, six general purpose I/O lines, 32 general purpose working registers, one 8-bit timer/counter with compare modes,...
Bil Herd Well the Bios says it all, burned out years ago, have some scattered memories of working for Commodore in the 1980s's. I also was licenced to fix TVs , CBs and had my Master Antenna cert (all Indiana commerce requirements) at an early age. Worked...
Hi all, welcome to the Hack Chat. I'm Dan, I'll be moderating today for our guest Michelle Thompson, who's here to tell us about what goes into designing hardware challenges for cons. I'm not sure I saw her log in yet, though - are you out there, Michelle?...
Primarily, I focused on excessive rainfall effects on agriculture in this project. However, excessive rainfalls can lead to numerous hazards, for example [1]: flooding, including risk to human life,damage to buildings and infrastructure,loss of crops...
