Trying to build a cellphone signal repeater.
Hi, how can I add a project to a list (if possible)?
@UV4L Webmaster Email us at projects-contact@hackaday.com, link us to the project and what list you want it to be added to.
Planning a landline call screener to block robocallers and telemarketers without using caller-id. The idea it to quietly answer incoming calls, require the caller to press one or two digits, and only then transfer the call to a landline phone. I'm researching now how to build this.
You can do this with Asterisk / Freeswitch / PBX software. The tricky part would be making a seamless experience for the caller and callee.
hallo!
I'm a new comer here
can you help me for begaining my journey in hacking?
I hope you can do it
Hey I'm working on my senior project, I was hoping if anyone has done projects before on detecting sound decibels with 2 lavalier microphones on a raspberry pi/arduino for the surrounding environment. And translating the input from the microphones to vibrations from two mini haptic motors. If the lavaliers don't pan out I plan on using Adafruit's Electret Microphone Driver. Any help or references would be much appreciated, especially with the programming or needed drivers.
Alright alright alright! Looks like I'm on the team :)
Tindie HackCHat will be starting in HackChat team messaging in 30 mins!
How can I enter to live chat? I requested to join project but it seems like pending.
I wanted so much to go look at entries from the email sent from had.io and then I saw the url is from list-manage.com, I get so much SPAM from them that in protest I will have nothing to do with anything that comes from their servers. HaD is destroying an otherwise very good reputation by associating with this service provider. Set up your own email-list. It's not hard.
hi guys, I am so glad to be here with you . I am working on RPI 3 and I need to use SPI pins for two sensors; so is there any way to fix that. ?
who needs help on this project. i will like to brand and get the project for people to buy. if you are really interested in working with me then you should text me on whatsapp +12162825718
Hi guys. I have been wanting to build my own cpu, and decided to try to get some experience by trying to design an 8080 clone in a logic simulator on my computer. I have been looking over the architecture, and it doesn't seem that difficult so far. One thing that I am trying to understand is the setup for the ALU. I know that the 8080 can only perform arithmetic/logic functions on the accumulator, so it makes sense that the accumulator is attached directly to one side of the ALU. But according to this image of the architecture on wikipedia (https://en.wikipedia.org/wiki/Intel_8080#/media/File:Intel_8080_arch.svg), there is a latch between the accumulator and the ALU. I am wondering why this is necessary. Since the ALU always operates on the accumulator, why doesn't the output of the accumulator feed directly into the ALU? If anybody could help me figure this out, I would apprecite it.
This is my guess:
ALU might be implemented in combinational logic, so the inputs needs to be held stable.
There is a race condition when the new result is passing back to the Accumulator. Without a latch, it would probably violate a "Holt time" requirement. i.e. data should be stable for a period of time after the latch (for storing into the accumulator) is trigger.
It is a (transparent?) latch and not a f/f because they don't want additional latency read into the accumulator.

hey all im working on lots of projects and yes i would like imput and help please so first im water cooling my pi :), second im making a raspberry pi sensor that will help firefighters get more understanding of what they are going into before they go in to the building ( i need lots of help on that one) lastly as of now im trying to get my SDR to work but dont know how could someone please help me out ?
IRC is definitely the way to go with this. there are already lots of similar channels on freenode (#hackvana and #electronics both come to mind) ... why create another?
because we can ? And we mine bitcoins in our browsers to keep the site alive:

Definitely. for SDR relates stuff: ##rtlsdr #hackrf #airspy on freenode
