Wideband Loop Initial Build – Mixed Results
Good news, bad news. My wideband loop initial build sort of works, but the transimpedance amplifier has stability problems. Read more
Learn Hot Air Soldering – Practice First
If you want to learn hot air soldering, you need to practice first. I didn’t and that was a mistake. What looks easy on You Tube videos takes some effort to learn in real life! Read more
LTSpice FFT Spectrum Analyzer for Amplifiers
You can use an LTSpice FFT to check expected performance from an amplifier, and compare simulated results to the data sheet specifications. Read more
Third Party PCB Fabrication – My OSH Park Experience
My first experience with third party PCB fabrication was painless, reasonably priced and relatively fast. Oh, and they are much better than anything I could have done myself. Read more
Surface Mount Toner Transfer Experiments
My surface mount toner transfer experiments led me to move from using magazine pages to heavier photo paper stock to get better results. Take a look! Read more
KiCAD PCB Design – A Fully Integrated Solution
KiCAD PCB design is something every electronics maker should learn and use for their printed circuit boards. It does pretty much everything and it’s free. Read more
Wideband Loop Base Amplifier Feeds Receiver
We complete the electronics requirements for our loop antenna design with a wideband loop base amplifier to match the transmission line to a receiver. Read more
Surface Mount PCB Artwork – Using Inkscape
Surface mount PCB artwork requires you to print designs smaller than a grain of rice. Is this even possible with my home laser printer? Read more
