Buy a better doorbell, sounds like an awful lot harder task to hack than it's going to be to get one with a decent range.

The actual sensor I used BME280 could actually be connected up to the i2c interface on a raspberry pi just as easily, the app would then be even simpler as it wouldn't need a MQTT broker, it would just read the sensor directly and store the results in the database, however, that wasn't the point...

Boards arrived and soldered, code modified to use STM32F722RE instead of STM32F402RE and bingo. Worlds most pointless project, but I learned how to use Kicad and somebody pointed out how to make pads that sink into planes (the chip bottom left as you look at it is a linear regulator and lets...

Alfred. Irritates me when I use a Mac that doesn't have it installed.

I can't actually work out what you're doing or wanting to do from that description, why have things got the same address (are you talking externally because of NAT?). is the embedded device on a VPN SIM or something? (We have customers who use static IP SIM cards, some use a real IP and others...

I found the original thread where that top one came from and the guy said he had the gerbers for it if you asked him, you need the Gerber files (and drill files) to get it made, you can't do it from the picture. I just modified my design, fixed an issue (those eagle eyed will see the voltage...

They need to supply the Gerber otherwise you'll need the original design file and a copy of the software they used to do the layout to generate the gerbers yourself. That second layout is appalling! lol. No idea of the sort of voltages involved here, but those traces don't look very big at all...

top image is the circuit diagram which gives you the types and values of the various components. The bottom image is a composite picture of the top and bottom PCB layers. You need Gerber files to produce a PCB, you'd upload them to JLCPCB and check it looks correct and get them to make them.

I started messing about with PIC16C84 (the original version before they changed the flash technology and it became the 16F84), built my own programming circuit for it connected to the parallel port of my PC.

Designing circuits is pretty easy (if your brain is wired that way), laying out a PCB can be fairly tricky depending on the number of layers you use and how compact you want to make it. I'm old enough that neither electronics or computing was taught at school! ?

Not a lot. It was mainly a test of the design software (KiKad) and the board manufacturer, I wanted an excuse to use the teeny tiny ARM SWD connector, it's common to find dev boards with the standard size SWD connector, but not the tiny one. I just wanted to have a play with the ESP-12F module...

Anybody else into electronics? I've been involved in electronics for 20+ years commercially, designing embedded systems. Got bored at home the other week so decided to see how far open source design software had come, so knocked up a small design (wifi and i2c breakout) and had the PCB's made...

Unifi FTW!

Bombjack was a cracking game.

Design classic though ;)

Sure is, one of the best speccy games ever.

Bought a couple of 48K spectrums (in good physical condition) on eBay, one was working and the other was faulty. Bit of probing around using the schematic and found an open circuit on a RAM chip, so fixed that and low and behold it sprung into life.

I’m tempted to install a UniFi G3 pro seeing as I have UniFi kit anyway and run their video server application on my NAS under docker.

Mental. Plus $39 each time you want to use it at an event. Knock that s**t up in a day! Lol

FileMaker is pretty much the standard when it comes to mac databases, the company is owned by apple.

Yeah, it was very weird. All I did was pull down the changes from another branch but then hell let loose. What I discovered though was that everything looked correct on the gitlab server, so I checked another machine and low and behold the code looked correct there. So deleted by local copy...

You know what I said about GIT... I moved our Gitlab server to our new NAS, my developer was trying to push some changes to a project but none of the remote branches were showing up.... Turns out the backup didn’t restore that project, so I redid the backup from the old server and restored it...

Awesome stuff dude. We are just working on a new design and it looks like I will have a whopping 1 megabyte of ram to play with! Lol

That’s why god invented GIT!

Well I'm moist. :smile:

What CPU is that? I just replaced my machine in the office, I’m rocking the built in graphics as I only ever access the machine over RDP.... I Posted a pic on Facebook of the task manager and my mate said “that’s not a PC, it’s a server!” Coffee lake 6 core with 32 gig of ram, builds fly on it!

The amount of equipment we've bought over the past few years is staggering. We have a state of the art pick and place line with solder jet printer. Means we can do JIT production and we can build prototype hardware in house as well. Not bad going considering we accidentally stumbled into the...

That's very cool.

Yeah, product has been shipping for a couple of years, but using somebody else’s antenna. Problem is, that due to the collapse of the pound and impending Brexit we needed to bring the antenna part in House. Lots of specialist equipment (£££) and a load of very complex engineering and time but...

Nice. I’ve managed to get an apprentice which has taken a load of work off me, took him a while to get up to speed with the Qt desktop software I wrote (he was amazed one person wrote it). I currently have a 24Ghz spectrum analyser set up on my desk in the office as I’ve been bringing up the...
