If I ever want to know where my wife’s cat’s are hiding I only need to start this 12 servo monster – I instantly have a horde of cat audience… I will mount the control system on the inside of the box, but I still have to sort out the battery & PSU. Knowing that…
I maintain Zero mounting holes on all my Hat’s because it’s an easy & cheap way to assemble a wireless control system using the capabilities in Zero W. The picture above show Zero W on top of a 32xServo Hat. I have only populated 16 of them, but all 32 are available since the Hat…
I am constantly looking out for IDE’s to improve my productivity in Software, so I wanted to share with you my recent experiences in the area. This review focus on STM32 development. Visual Studio. Having used Visual Studio since it came around as Visual C++ 1.0 some 20+ years ago it has always been my…
Just the first 3D draft of my Servo Module. I still have the Raspberry PI Zero W hanging on the back of this – we don’t need to populate that header, but had plenty of room for it so just left it there. on top left you see jumpers to select Servo and Servo Signal…
The Servo Module forced me to think about isolation and made it obvious that I need 2 x 5V supplies in cases where 5V is used for Servo’s etc. I removed 48V as option simply because 48V is used for higher effects/currents. Pin 23/24 is now the 5V MCU supply that must stay isolated from…
I don’t show to much schematics in here simply because it’s a bit difficult to copy them into here, but had to show this – this is the first time I use a photocoupler. I decided to try PS2801 after realising that a long range of photocouplers use the same package. I am not sure…
This is a 5″ display and the keyboard I just ordered. I think the size is about correct. The trouble is more finding a TFT display that hide the HDMI on the back (inside) rather than demanding cables extending to the sides. I actually need a workable console for Raspberry PI that include both keyboard…
Not the most interesting topi, but this keyboard fit into my hand and accidentally have a layout that seems to be good for a developer. I ordered one to try out – actually could be an idea to make plug the keyboard into Raspberry PI and make a Pocket PC – it just need a…
I have dropped the GSM and Raspberry PI modules since the Ethernet module incude those. The ones with colors are coming up – thought I will also start focusing more on the rest of the network. I have produced several small mini modules in the past that I also want a new revision off.
I have written about STM32F105RB and why I chose this before. Sample prices on AliExpress do variate, but I noticed some batches of STM32F105RC for 1.8 USD each so I purchased 10 of them – they arrived today and I will stick one of them on a breakout board later. ST’s own price for this…
