Not a smartwatch
Not a smartwatch
Hi there
I am searching for a watch that has some GPS and walkie talkie function – and NO MORE. I don’t want a smartwatch with all bells and whistles. Just GPS tracking and some form of talk function. That’s all. Not even SMS.
Not sure if that exists. But if you can help me find this product that would be awesome!
Thanks

finished 1 half of my symetrical power supply project
for the positive voltage rail its an lm317 regulator with a bd912 transistor and for the negative rail its going to be a bd911 transistor with an lm337 regulator. i heard using regulators for audio amplifiers is pointless but also not since it may remove oscilations and hum,get rid of expensive 4,7mF(or bigger) capacitors as well as give me a stable +/-20V regardless the current which may be usefull.

Starting a family
I am starting a family or a addiction 😅 -The arduino nano with the led is a tv b gone -the orange thing is a m5stickc plus2 -the usb purple thing is a cjmcu badusb -and the white thing is a flipper zero with external antenna [link] [comments] |

I’m making a USB-C powerd, attiny based IR interpreter
If you have your TV attached to a good, mid 2000 Hi-Fi, probably you have two remotes laying around, or if you are a retro gamer, you probably have to get up from your couch to restart or turn off tour PS2. This device allows you to control all from a single remote It respond to a received IR code with a previously programmed, corresponding IR command to control a second device. It is fully open source and there’s a github repository for all the work I’ve done so far [link] [comments] |
Unknown chip in motherboard
Hi my laptop died and started to troubleshoot it. I found capacitors in these portion of motherboard to be shorting. Upon injecting voltage on one of the caps, this chip “eHCSA” was getting hot on FLIR camera. Does anyone know what this chip is and where can I order one? Can’t seem to find any on Aliexpress [link] [comments] |

fixed a Bench power supply today
broken transformer, insanely dodgy mains power switch (probably Stolen from a lamp sometime) and a shitty solder Job on a 7805 all added up to the thing ending in the scrap pile. fixing all these things made it work again, have to say is a decent low voltage low current supply. [link] [comments] |
I thought the STM32 was a series of 32 Bit wide-market microcontrollers?
They are now making 64 bit full Linux capable processors under the “STM32” name. I can understand putting the STM32MP1 series under the STM32 brand, but this should just be a new line of chips at this point. [link] [comments] |
Replacement capacitor
I know enough about electronics to get myself in trouble but not much more. My wife's Grandpa had this old 8mm projector and looks like a capacitor was added at some point. It hooks up inside to this transformer (I think). The projector surprisingly works great! But the motor starts to slow down after running for 10-15 min and the capacitor gets real hot. I'm assuming it's going out? As soon as the motor started slowing down I turned it off so I wouldn't break anything. Any ideas on what the specs would be for this capacitor? I looked online and couldn't find any info on a "R50T1 Mallory" capacitor. Any guidance would be greatly appreciated? [link] [comments] |
Upgrades!
I’m a senior hardware engineer and one of my favorite pastimes is to take electronic kits that are online or in store and see if I can approve on them a little bit one way or another. I seen this mini “pong” retro arcade kit for pretty cheap and I was like oh, this is screaming for a custom 3-D printed case. Though after I assembled it, I found out that the biggest weakness was it had one of those really tiny piezo speakers. It was also enclosed in the case, so it was really quiet, so I added a KA386 amplifier that I had laying around. This worked pretty well and made it way louder. It’s probably not the most quality audio amplifier these days, but it’s dirt cheap and it works for the 8 bit sounds. [link] [comments] |
First Project on perma-proto board
First Project that has moved from breadboard to something more permanent. None of the potentiometers are square, and some of the solder joints may make you cringe. But that's how we learn. The code runs about 350 lines of circuitpython. What is it? A fencing training assistant. [link] [comments] |
