I want a new monitor to use with my laptop at when I'm at my desk. It'll be for productivity, coding & 3D stuff mainly but also probably some gaming. 27" is the ideal size on my desk with my laptop next to it.
A 4K 144hz display is £750+ so I think that's out so the choice is either a 1440p@144Hz or a 4K@60Hz. Both options can have freesync.
My laptop rarely exceeds 60fps anyway so the 144hz is maybe not useful on most games I play. But thinking of the future I might build a new desktop, with probably 3080 or similar, some time in the next couple of years so maybe.
£400 would bet either the LG UltraGear 27GN850 1440p@144hz IPS or the LG 27UL850 4K@60Hz IPS
Seen here some time in the early 80's all dressed up for some event with my Dad (1936-1997).
Sadly dementia took it's toll this year, but it's amazing how long she remained fit, healthy and well enough in her mind to know her family.
Love you Mum.
I've wanted to make a UPS (Uninterruptible Power Supply) for a long time, but I took a while to figure the best way to do it.
It has a 12V 5A power supply to power the Server, Modem, Router * Network Switch. This way even with a power cut the Server and all the required network equipment to keep it online will all be powered by the built in lithium-ion battery. The battery is also charged by the mains power.
The difficulty was because the server and modem are 12V, the router is 19V and the network switch is 5V. So I added the ability to add modules that slot in to the back of the UPS that can provide different voltages. The modules can also be swapped out for different ones in the future if need be.
The UPS monitors the voltages and current of the mains power supply, battery and the output. This information is shown on a small OLED display on the front of the UPS and also sent to the server via a USB cable. The server monitors the data from the UPS and can then shutdown safely if the power is off and the battery is running low.
I'm not completely sure what the capacity of the battery is but I think it should be able to power the whole system for a few hours if need be.
It's not perfect and my decision to package it so tightly has caused a few problems but the hardware is complete and now working but I still need to finish the software side.
The leaked specs for the new Samsung 980Pro show insane speeds, 7GB/Sec Read & 5GB/Sec Write.
But notice that the endurance of the drive is lower than the previous generation of Pro SSD.
Of course unless you are reading and writing large files you won't really notice any improvement.
Apparently while thousands are dying from coronavirus Trump thinks it's a good idea to have his campaign text voters about his new colouring book! XD
To fair to Trump supporters this book is probably on a level they can understand.
A neighbour found this little wasp nest, no longer with living wasps, and wanted me to take some photos of it. Here are a few for your viewing pleasure.
I've had this old bench grinder for a long time and the tool rests that came with it were crap. It's not my main tool sharpener, I have a Sorby Pro Edge for that, but it's still useful. Finally I've finished making some fully adjustable tool rests. They both tilt and adjust in height/length at the top and bottom, and have a slot in the top that fits all the accessories from my Sorby Pro Edge.
Yay!
Sadly my little angel had to be put down today. She was 16 and had been having problems keeping any weight on for a quite a while and she finally had run out of energy.
She'll be greatly missed.
As always she chose the most awkward time possible to need to go to a vet and especially awkward as today would have been my dads 84th birthday.
I had many wonderful years with her so I'm complaining :)
I bought a new, but old stock, Nokia 3 phone to replace my old Sony Z3C that had finally died. I use it as a mini-tablet in my workshop for playing music through speakers and photo graphing things as I work on them so I can remember what I've done. It was only £40 which for a brand new mini-tablet is a bargin!
On receiving it I decided to root it to make it more useful. Rooting is usually pretty straight forward but this time it fucked up :/
No problem I thought so I followed some advice to fix that problem and try again, but it fucked up even worse.

You get the picture.
At this point I have a phone that won't turn on or fully off, it just buzzes every 15 seconds and that's it :/
As a last resort I found a guy in India who had a video of him fixing the problem and a single package download with everything needed. 3Gb of downloading later I try it and fuck me it actually worked!!!!!
I don't understand why it kept fucking up and the things to fix it for other people failed for me but I'm thankful it's fixed.
I now feel totally fucking drained and my brain is numb XD
I was given and old laptop for parts and decided to use the reuse touchpad to make a separate touchpad to use like a mouse.
It uses and Arduino Pro Micro to get data from the touchpad via it's PS2 (old keyboard and mouse) interface. The Arduino is then able to act as a standard PC mouse (HID device) so it can used just like any other mouse on a PC. Mac or any device that can use a mouse.
I've included the a picture of the 3D design below so you can see what it's like inside.
The hardest part was designing buttons that worked reliably over the entire length of the button. There is a tiny button glued in the centre of the button pointing down and the 2 its coming off the button act as a hinge and also hold the button in place. I first tried a prototype button with a metal bar across it like a space bar has on a keyboard but I couldn't make it work reliably and it was very difficult to put together.
It took me a while to come up with a good way to fix the touchpad to the base and still be able to take it apart in the future so in the end I glued 4 little round mounts to the base of the touchpad and inserted M3 threaded brass inserts in to those. Then to fix it all together I just need 4 short M3 counter sunk bolts through the base.
It works great and I'm really pleased with the simple design.
I've wanted a milling machine for a very long time and finally saved up enough pennies to get one. It's only a small one suitable for hobby work but it'll probably do anything I want.
It's a SEIG SX2P in case you were wondering.
I already have some modifications in mind like a tachometer & DRO (digital read out) for the X, Y & Z axis.
