Some weeks ago I wrote about using a silhouette portrait craft plotter for cutting solder paste stencils. The described process uses the collection of the gerber2graphtec python scripts to process the fabrication data from kicad and send the cutting instructions to the plotter. The solder paste stencils I did cut for the VESC came out… Read More »
Some more news on the previously hyped the $99 Eachine EV100 FPV goggle. Yesterday was bugfixing time (the distorted and gray bars are history!), today I found out a new tiny bit on the inner workings of this thing. This post is about the video receiver module. When I first opened the goggles and did… Read More »
There have been a lot of rumors and discussion about the $99 Eachine EV100 FPV goggles recently. I already did some teardown, component analysis, component identification, and analyzed the “diversity” feature of the receiver in my previous posts. With the goggles being more and more used, people experience a new problem with these goggles: Depending… Read More »
Roughly one year ago I started to work on the 1S tinyPEPPER ESC. At first, I did not want to design an ESC on my own. I had just finished my first tinyFISH FC PCB routing and was browsing banggood for a tiny and lightweight 1S ESC. To my surprise I could not find anything… Read More »
This post is a follow up on my recent Pagoda3/3B panel design. Recently I have been asked to do an updated revision of my previous pagoda antenna panel for easy ordering. Maarten Baerts recently updated his great pagoda design. My pre-previous article on how to order 160 antennas for 40 bucks was a great success… Read More »
I have been looking for a holder for my T12 soldering station tips for quite a while now. There is this one on banggood which looks good but seems to be priced a “bit” to high. I mean all it takes is some plastic and some holes. Wait plastic? Why not 3D print one? Firing… Read More »
As you might have read I recently started to document the assembly of Benjamin Vedders insane 12S 50A (240A peak) motor controller called VESC. This is the third post in this series. In the previous VESC article I showed you how to cut a stencil for solder paste application on your own. This time I… Read More »
I recently started to assemble a VESC brushless motor controller on my own. This is the second post in this series. As you all might know I do a lot of prototyping. Nowadays you can get your custom PCBs made at a very low price. I get most of my prototypes done at OSHPark.com. Three… Read More »
This is a follow up post to my previous blog post on how to replace stiff wires on micro brushless motors such as the Racerstar BR1103B. Last time I cut and re-extended the wires outside of the motor. Encouraged by Sams blog comment I got ready to sacrifice one of the motors for science! To all… Read More »
It’s all about power — At least you get the impression when you follow the latest builds showing up on youtube. When I started with building quadcopters it was quite common to use 3S batteries with three lithium cells in series. Right now most quadcopters (other than micro builds as e.g. my pepperFIISH) will be… Read More »
