What's the best place to learn everything about electronics such as designing and making your own pcb's, why you put what part where and how to get started, ...for free? Also is there such a place with clear and distinctive photo's?
When I try to edit my details on my hackaday prize entry, changes aren't saved unless I delete EVERYTHING and paste in an entirely new text. Even then it seems to have intermittent issue.
Got a question about SDR. I get the basic idea: sample a wide signal range, digital filter to the band you're interested in, then further DSP to "decode" based on format (FM, AM, packet radio, etc etc).What I don't get is - I was taught that radios...
Engineer to build light color detector based on webcam. Ambient light in the room has to change to that color (RGB LED).When correct color is detected the door should open.We have coders and we have engineers back in Europe, but it is better if we find...
So, I will be visiting Germany in August, and need to plan my itinerary from now, to get flight tickets and visas and everything.Wanna know about places of interest to a hardware hacker / maker. HackerSpaces ? Fab Labs and such - Museums, places...
I have built a circuit that doesn't work. (This is not unusual for me.) The circuit uses relays to count pulses from an old rotary phone dial... or is supposed to. I'm using a combination of the following circuits from http://www.electronixandmore.com/projects/relaycomputertwo/index.html (their...
Hi all- I need to deadbug wire a bunch of temperature sensors for a prototype, and would like something more robust than just the solder joint to hold the wires in place. Are there any preferred epoxy brands or types that I could use to put just a drop...
I have an HTC One M7 that died a while ago. During an update something happened and it will no longer boot. I have tried everything and after a lot of research have discovered that this is a frequent problem that can only be fixed if the phone had security...
From Mike Rankin's blog:https://0miker0.wordpress.com/2016/10/12/samd21-giveaway/What:I’d like to give away one SAMD21 logger/sensor board to someone, wherever in the world you are.Why:I’m a hardware guy, not a programmer. I’ve had fun designing this...
I am looking for software for inverse parallel kinematic equations. I found lots (including OpenRave) but everything seems to be for series robotics and not parallel. The Project is a half inverted arc delta robot, here -https://hackaday.io/project/18186-arc-delta-3d-pcb-drill-and-other-failuresI...
I am working on a project with the ttgo T-watch which has an Acsip s76g sip which has a lora chip and gps with a uc in a sip. On the t-watch the only coms is via uart. The T-watch also has an Axp202 i2c power control chip. It allows to select the voltage...
This is the idea, for a RC flying toy:A single propeller, or a small centrifugal compressor blows air into a reservoir which is the body of the flying machine. The reservoir can even be made of textile material. So it will...
my uncle is hard of hearing and i myself am huh'ing a lot more. as i have read about the smaller computers being produced i wonder if someone could build a handheld 7" lcd or led screened micro computer with voice recognition.in 1998 i had...
The bi-color matrices I ordered turned out to be common-anode ones, and not common-cathode as I expected. This means that I can't drive them with the HT16K33 chip as I planned, as it only has 8 cathode pins. I can't even use two such chips to drive the...
Liveboot is still useful, small utilities can liveboot and run wonderfully as a system to learn on, sandbox small projects on, or even to install from or repair systems with. We've even got some hacks for persistence, where your settings stay the...
