Software and hardware reviews
Previously, I covered the Dragino LG01 Single Channel LoRaWAN Gateway, a low cost solution good for testing basic LoRaWAN communication setups. I needed a better gateway and I was about to go for the german IMST IC880A gateway when I stumbled upon a Chinese variant named RAK831, that was cheaper and offering the same features. The RAK831 and the IC880A boards are almost identical in terms of Semtech chips used…
I already covered the impressive LPWAN LoraWAN technology with a proof of concept remote air quality monitoring unit based on the BME680 from Bosch and the RN2483 from Microchip, in a previous post. The device, capable of measuring temperature, humidity, pressure and VOCs can run for months on a single cell battery, thanks to the low power LoraWAN communication solution. It can send real time data on distances up to…
I’ll have to go straight to the point: get yourself a CNC router now! I’m serious: I used to make my PCBs dual layer and in the kitchen, as Hackaday folks like to show on their Twitter from time to time, but looking back, I can’t understand how I’ve done without a CNC router so far. And if you’re like me, and you probably are since you’re on this blog,…
I don’t change my tools too often, and those that I get stay with me for a long time. These are the things that extend my hands and allow me to freely express my creativity. At least for when it comes to electronics. I already have my excellent ZD937 and the Yihua 858D and these two stay side by side in my daily activities. But recently as a young parent,…
Finding the right 3D printer is not an easy task, considering the many options on the market. Many sellers claim unprecedented innovation, when instead all they offer is just another open source design at inflated prices. I knew I wanted a delta design, and a robust frame to better control vibrations, preferably metal. For the rest the more hackable the platform it was, the better. I opted for the one…
I tried, but there was no way to properly solder the BME280 tiny sensor using the soldering iron alone. After destroying one sensor and almost damaging the PCB, it was clear I needed a hot air station for my work on the uRADMonitor-D project. I opted for the 858D, also reviewed on Dave’s EEVBlog. It’s my first time using a hot air station and the BME280 is really a very…
Like with all measurements, it will be very hard to find two different devices indicating the same readings, especially when we demand increased precision. We now know that there are no such things as absolute time, absolute space, there are no synchronous clocks. It is the same with the absolute measurements, and in some cases it’s becoming more relevant to observe the change: if we see increasing values, we know…
Some impressions on the Google Tango Hackathon held in Timisoara in April 2014. See one of the Winner projects, the Camera 3D and some insight on the new device from Google.
The CDV-717 is a very high-range gamma radiation ionization chamber detecting instrument, manufactured by Victoreen back in 1964.
The CDV-750-5b Dosimeter Charger is a self contained battery-operated instrument.
A short review on my new Christmas gift, a neat digital soldering station, ZD 937, and a quick light installation that I did with LEDS, running directly on mains , 220V, using the ZD937.
Read a post on my new acquisition, a Bauch&Lomb compound binocular microscope, a high quality tool, put to some good use to capture a few micro photographs. It can get up to 1000X with its current optics.
A short review on a Mac Mini that I recently acquired. I plan to use it as my new fixed workstation instead of my older P4 PC.
For my first oscilloscope, I opted for the Atten ADS1102CAL. A few months after, I could say I’m extremely happy choosing this robust device, that does an excellent job on my workbench.
The laser keyboards use laser and infra-red technology to create the virtual keyboard and to project the hologram of a keyboard on a flat surface.
The DRSB-01 is a simple Geiger Counter device that can be used to detect normal vs. dangerous levels of ionizing radiation (gamma and beta).
The CDV700 dosimeter variant 6B (newer) and a few mods to improve functionality: audio connector and bnc connector.
A short review on the Radex RD1706 dosimeter, how good it is, and how can it be compared to other dosimeters, eg. the Terra-P MKS-05.
The terra-p Radiation dosimeter can be used to measure Gamma, Beta and X-rays.
