The finished work from yesterday is now in full colour in 3D… 1️⃣ 1 pc of TLE2074 2️⃣ 4 pcs of 100k 3-turn resistor trimmer 3️⃣ 1 pc of Hamamatsu S5991-01 Manufacturing ready and already ordered boards are being manufactured
TIA02C
New PSD sensor board
🛠🛠🛠 New type of TIA board for PSD sensors The Hamamatsu PIN photodiodes and PSD sensor projects go well and I have another task to design a third type of TIA board. This time for the S5991 PSD sensor. The
Analogue divider boards project
🏭🏭🏭 Manufacturing of the divider boards The BLE demonstration project is done and I can move forward to another project. The analogue divider boards for Hamamatsu PIN photodiodes have been waiting for a while, mainly because of the component shortage
BLE demo for Beny-devices part 2
🐈⬛🐈⬛🐈⬛ Programming and testing of the @Beny-devices demo project Yesterday, I was working on assembling and soldering the demo boards for Using Templates guide released as support for Hardware Design Templates. Now, I am tuning, programming, and testing the boards. CircuitPython allows
BLE demo for Beny-devices part 1
🟦🟦🟦 Bluetooth @Beny-devices demo board soldering The Using Template guide was built around the demonstration project for a smart BLE sensor device. Now I am working on the real device. The first part is soldering. The board has a double-sided assembly. The
Safe terminal soldering
🏭🏭🏭 Back to the smart controller board The crucial common part of the firmware has been finished so that I can finish the assembly of the smaller boards. Why I have been waiting till today? Because I was not sure
I2C+RS485+PWM
⚙️⚙️⚙️ I2C, RS485 and PWM support programming Yes, the board works well, so I am currently working on the 1️⃣ I2C bus FW support 2️⃣ RS485 interface FW support 3️⃣ PWM output FW support So far, everything works, and I
Clear to proceed with big ones
🏭🏭🏭 Finishing the assembly Today, I am going to finish the assembly of the bigger controller boards. I have tested them successfully. 1️⃣ 3V3 linear power supply works perfectly 2️⃣ 5V switching power supply works perfectly as well 3️⃣ 10V
Test and program check
⚙️⚙️⚙️ Testing, programming The Controller boards I assembled at the beginning of this week need to be checked, tested, and initially programmed. My task for today is pretty clear. 1️⃣ careful optical check of all boards 2️⃣ DC resistance check
Soldering iron tips
🖊🖊🖊 Soldering iron tip care I was asked some time ago for soldering iron care tips and tricks I want to be brief: 1️⃣ avoid using lead-free solders – it eats your soldering iron tip like crazy 2️⃣ avoid using
