Not long ago I purchased this neat and compact DC to DC Buck Boost converter that performs reasonably well. It has a maximum output of 38V, 6A and has more than enough flexibility and features to be a secondary power supply in my lab. I recently found a review of this product by Julian Ilett on his channel (which […]
For a few months now (and after successfully using a cheap USB analyzer with my Pocket C.H.I.P) I’ve wanted to make a sort of standalone Logic Analyzer / mini linux machine that I could have on my bench. I originally wanted to use one of my C.H.I.P boards, but I soon stumbled upon a bit of a difficulty: It’s […]
A recent discussion on the Pocket C.H.I.P forums made me dig up memories of my time with DJGPP (a wonderful DOS port of GCC), and its quite functional text-based IDE; RHIDE. I thought that it would be great to have RHIDE running on my Pocket CHIP for doing simple C/C++ development on the go, as […]
I have a very simple “audio/video” setup in my room. My main computer display doubles as my “TV” for playing videogames and watching movies. Technically speaking is just a 22″ HDTV with a bunch of input options, which I have connected to all of my devices, mostly through an HDMI hub, so I use the same screen […]
This is the second part of my adventure building a UV Exposure box, in which as you can see, I actually finished the build. In the first part I made the structure and planned the electronics. This part covers a whole lot more, distributed over many weeks doing small things here and there.
Like a year ago I made myself a nice little desk clock that has worked fine since then. But recently I revisited the project to do certain improvements. For starters I wanted a smaller board so I could fit it inside an enclosure. I also wanted to power the clock from a rechargeable 18650 battery and add […]
I love DIY/soldering kits, and thanks to online marketplaces like eBay I’ve been able to purchase and assemble a number of them for the past few months. One of the last ones I got was a very basic but useful function/signal generator, whose only problem was that it required a power supply with +12V/+5V/-12V rails (it also arrived already assembled despite being […]
In my neverending quest of improving my homemade PCBs, I discovered that adding a soldermask to my boards is actually not a hard task, thanks to a relatively simple process that involves UV-curable paint. Now, while using the sunlight as a UV source should work just fine, I decided that it was time to build a proper UV […]
