Pulse Generation Circuits
Log from DC Current Transformer
In the last posts we saw how a fluxgate works in simulation. Simulations are all good when you can just add a pulsed voltage source - everything is perfect. In the real world, we have some challenges:1) We need very low DC offset to avoid...

Testet the X Axis
Log from Homemade PCB-Mill / Laseretcher
First Test of the X-axis was succesfull. The axis don't have a belt at the moment, because they didn't arrived at time, but a sholace will works fine ; ). Next step is to Design the new holder for the y-axis linear shafts, with a included beltholder....

Mounted the motors outside
Log from Homemade PCB-Mill / Laseretcher
Now the Motors for the X-Axis are mounted outside, so the Working-Area gets bigger.

Log from MIPI DSI Display Shield/HDMI Adapter
We have a working Galaxy S4 AMOLED screen, 1920 x 1080. A QHD screen from GS Note 4 is waiting to be tested soon!

Set the stage, cue the music
Log from Coming soon...
I have always wanted a robot arm. Youtube Kuka and you'll understand. So in college after building my Photovore (see "things I've built" section of my profile), I bought some servos, wires and the Lynxmotion SSC-32 Servo controller (and arm control software),...

Pi Supply added
Log from RaspBox - Home Automation & Cloud
Just a small project log to say that I've installed a Pi Supply on my Raspberry Pi in order to bring ATX-style power supply to it. The Pi Supply website gives a script to run on the Raspberry Pi to detect a button press from the Pi Supply and halt...

Wireless adventures using the NRF24L01+
Log from Smart Greenhouse using a Raspberry Pi & Launchpad
When browsing eBay and looking for the NRF24L01+ one is swamped by a multitude of sellers selling these dongles for really low prices. The current rate is approx. $1.60 to $1.70 and you get a lot for that amount of money, a transceiver capable of:Sending...

Quiet, but fruitful
Log from Smart Greenhouse using a Raspberry Pi & Launchpad
The past two weeks have been very busy with work. Most progress on the greenhouse has been made in the preparation and thinking department. Several design choices have been validated.Beaglebone BlackAlthough everything works like a charm on the Raspberry...

Some progress at last!
Log from Mini Laser Cutter
Had a Sunday afternoon free, couldn't resist banging something together with whatever I could scrounge from the dustbin outside. Looks pretty cool!:Next, I'll make some proper slide rails, re-build the frame out of something better, add the LASER (a...

Temperature Sensor Integrating (Success)
Log from Peril-Sensitive Sunglasses
Integrating the TMP36 temperature sensor was simple, I've used it before. It looks like a transistor and outputs a voltage proportional to temperature. Adafruit has a thorough guide on its use.Making the sensor work was easy. Using...

W5500 test PCB
Log from Home security
As gateway board is having issue with Ethernet crosstalk, I have created small 2.5 x 5 cm breadboard friendly PCB. I will use it to verify my new component arrangement and not spending another 50 USD on full gateway boards. I used differential trace...

Battery node with USB charging
Log from Home security
Shortly after introducing rearranged PCB layout for nodes, I realized that I use LiPo batteries in all my battery powered nodes. That is making no use of the step up capabilities of the DC to DC converter. When designing it I was wanting to have possibility...

Turning off gateway.
Log from Home security
Some weeks ago I have decided to turn off older version of gateway (version 1.5) and replace it with new version 1.7. It was running for over a year and a half. Also it was not so easy as it used RFM12B radio module and all radio nodes need to be replaced...

Realy nodes
Log from Home security
After some testing I have finished new relay node. As all nodes it is Arduino compatible board with ATmega 328P clocked at 16MHz@3.3V. Size 6.1 x 5.6 cm.On-board AC/DC power supply. Input 100-240VAC, 50-60Hz. Output 5V/3. Fused with TVS on input with...

New wireless mini node with RFM69
Log from Home security
Lately I have stared to play even more with various remote sensors wirelessly connected to OHS gateway. I have used my standard radio nodes, but its versatility is somehow to much for small wireless node. To save space and gain easier access to pins...
