To start off, thanks to JLCPCB for sponsoring this project as well as providing pcbs to get the ball rolling. JLCPCB Prototype for $2 (Any Color): https://jlcpcb.com The hardware requirements of this project are fairly simple: two buttons for setting...
OK, here we are at the top of the hour with a lot of new virtual faces. I'm Dan, I'll be your mod today. Let's welcome Mike Gardi to the Hack Chat today, to talk about the wonderful pieces of early computer history he recreates from scratch. Hi Mike!...
Altoids – they've been around since King George III was on the throne. These curiously strong mints have had a storied history, a copy of which is included in every tin. They taste pretty good, but most hackers and makers are more interested in the pocket-sized...
With over 160 years of history under its belt, Morse code is by far the oldest digital signaling system known to man. Originally developed for telegraph systems, [Samuel Morse’s] code has been sent over wires, via radio, and even with flashes of light....
Hackers, makers, and engineers have long had a love affair with number crunching. Specifically with the machines that make crunching numbers easier. Today it may be computers, smart watches, and smartphones, but that wasn’t always the case. In the 50’s...
In the photo attached you can see the telephone handset I wanted to use with this project. The handset was sonic welded completely around the edge and on the supports. Ended up having to slice it in half with a hack saw, not my finest work. I connected...
I've been pondering a second version of the staff for a while now and what with burning man 2014 right around the corner I think it's time to get serious.I'll document the whole process start to finish here. Hopefully with any luck and a bunch of help...
With the coding for the project coming along nicely I figured I might spend some time transforming it from a pile of wires on my (currently traveling) roommate's desk into something a little more manageable. I had finally procured the last few pieces...
I'm super busy so bear with me. Gulf Coast MakerCon is in less than two weeks, our makerspace soft opening is a week later and I'm doing the Galileo Hacks project with Make, so my dance card is full. I've made a lot of progress on the Lunettic, but I...
Prototype is working on bench, connect over bluetooth, answer phone, mic, speaker and dial with rotary. I'm using an STM32F103 development board to send commands to the Bluetooth module over UART, the STM32 is also encoding the pulse from the rotary...
A speaker has been implemented and now plays the square waves generated by the CPU. I can tell by the sound and the pitch of it that it's not perfect, but it's something I'll work on. The speaker is controlled by the CPU toggling one GPIO...
OK. I took delivery of the new amplifier boards, pre-amp, and speaker protection board a little while ago. Unfortunately they are slightly too big (or more the wrong shape) to fit in the original amp board locations.So after a bit of jiggery-pokery,...
After I accidentally left my laundry to rot in the washing machine one too many times, I decided to permanently fix the problem with a Spark Core. I rigged it to cheap door sensors (http://www.amazon.com/Wireless-Doors-Windows-Security-System/dp/B00CDCIP00)...
Goals:- Replicate functionality of the 'verbal morality statute monitor'/swear detector from Demolition Man.- Detect when a swear word is uttered and sound a warning bell / flash lights / print out violation ticket.- Replicating the look of the device...
Ported everything over to the Raspberry Pi and it works great, check out the video: The only gotcha was that Raspbian ships with USB audio configured off, but after a small config tweak it worked just like on the PC. Very happy to see there...
