For the last few years I have been renovating a house . Due to all the work going on , I currently only have a temporary electronic workbench setup in an unfinished spare room with limited space. I wanted some of my tools to be stored within reach sat at my desk . Unfortunately the IKEA desk had drawers and a cupboard but were either not suitable or full of stuff. With my 3d print taking up a large chunk of my desk I thought of adding a drawer or two under my 3d printer. [...]
I have recently made an Infomation display for a friend using an ESP32 driving a Nexiton HMI LCD display This is the first time i have used these displays and have been impressed with the results . These are serial based displays that have a HMI that is first designed on Nexiton’s IDE desktop software [...]
Unfortunately i haven't had a lot of time for home projects recently with work and other commitments but with the current situation i had more free time and finally had to time to work on projects which i enjoy ! I have found myself sometimes using my TS100 soldering away from the bench and one day i was watching https://www.youtube.com/watch?v=8uGS11yuVyo where Adam Savage from Tested made a portable Ts100 Soldering Iron powered by a Dewalt power tool battery. This was a great project but i wanted something more compact without all the storage. [...]
A few years back i made a compact bench PSU based on a DPS-3002 module and a 24v PSU. I have since made a improved version that also includes the ability to run on my power tool batteries making it ultra-portable. [...]
I recently came across a DPS3005 PSU Module with PC control option , i have used similar modules before in a bench power supply and was impressed with the results . With the launch of a new version that included PC control i decided to order one ! (Banggood.com) A few weeks later it arrived ... [...]
Following on my previous (project / Guide) RFID login) , i have been working few improvements to the arduino software example. The biggest change is now having a serial terminal based menu interface. Also a few security concerns have been addressed, this includes limiting the number of wrong tries. As with the previous version not for [...]
Day to day life has got in the way of my projects recently but ive finally found time for a very quick and cheap Board Soldering aid with mainly things i had laying around. This is really quick and easy to build and i have personally found this very useful when soldering. [...]
I wanted a simple way of quickly logging on to my computer without having to typing my password in and did not want to have no security either. There are various products on the market that would solve this problem from fingerprint readers to proximity dongles but i decided to see what i could knock up with parts i mainly already had. Looking in my micro stuff i had a RC522 RFID tag reader 3.3v : Also an 3.3v arduino Leonardo clone aswell based on a sparkfun pro micro which also can act as a USB device such as a keyboard. This is useful as if a 5v arduino was used a level shifter would be required due to the RC522 not being 5v torrent. [...]
I finally got a new desk and decided i didn't want to keep bending down to plug stuff into my computer nor did i want the computer on show. I wanted a few more functions than just a desk USB Hub. [...]
Few weeks back i reviewed a GM328A Component Tester and this comes just as a uncased PCB . I decided to put my 3D printer to good use and searched the inter-webs to i could find a few cases examples but in the end i decided to just design my own. [...]
