Operate as follow: Install HC-05 module on Interface board J4 connector (I suggest you to apply a layer of double-sided adhesive between the module and the pcb) Insert Interface board on top of Arduino mega board Apply Control Unit Case. Important:...
This weekend I connected the Nick Williams 102 throttle body to my 2002 Corvette to look at how it fails. At about 15% throttle opening, the blade starts to oscillate. My first thought was that this was due to the PID gains being too high, but it...
At this point, the project is functionally complete... but there are some firmware improvements I intend to make going forward:Monitor the "peripheral detect" line and detect a keyboard disconnect event, then attempt to re-connect when detected...
The main issue with the original prototype (besides being ugly) was the lack of a battery. To resolve this, version 2 is designed around a power path that uses a TP4056 LiPo charging module and a 800mAh+ single cell LiPo battery. [Andreas Speiss] has...
Finally the weekend is here, and I had some time to actually program and test this device. Right away I found this tiny little problem on the PCB:It's hard to see, but there is a trace between PA01 and PA02 pins. One is part of the key matrix, the other...
To know the position of the servomotor axis, LibreServo uses the AEAT-8800 16-bit encoder. This encoder replaces the potentiometer that the servomotors have and with it we get much more precision and allows the servomotor to rotate 360 degrees. To achieve...
Now is 2021-11-28. At the time I created this Hackaday page:- I have spent about 8 hours over 4 weeks dismantling, waiting for parts, repairing, breaking, and repairing again the switch mode PSU. At that point was when I discovered the device...
If cloning an 8-bit computer in FPGA, one might as well clone the best one around.I feel that the Atari 6502 series are the best, for the following reasons.Full-custom ASICs designed and built for the job.Sprites and collision detectionFewer socket contacts...
-The client has been updated to version 2.0.4-calibration PH-fix PH timers PH sensor calibration instructions:1. The sensor is calibrated against two test liquids with a known pH.2. The pH level of the calibration fluids can be anything (try to use...
The old pump pulled down the humidity to the 20's. The indoor swamp cooler didn't affect the humidity near the window. The decision was made to replace the pump, after a very noisy final TPU drying. Lions have lived in a very noisy environment...
To solder using the generic heat gun, you need to set it to max power and min flow and remove all focusing attachments. 1. I applied solder paste (Next time I'll order a $8 stencil): 2. Then I aligned the controller. 3. I used a spare PCB and a multimeter...
Your printer prints at some positive height in the Z axis above the point at which is makes contact with the Z limit switch. This switch can be heard clicking when you tell the printer to home the Z axis. You need to set the height of the bed such that...
Fuelled off the good vibes of the Simcity 2013 soundtrack, I've ported over the circuit from my EasyEDA schematic that relates to the ADC:The first thing that I did was create the 3D model using the wizard, which also creates a PCB footprint along...
After considering my options, I've decided to continue trying to obtain a solution with 3.2mm ball chain. I've now modelled the front sprocket solution. I've spaced the front and back sprockets to be an integer spacing appart (I think 20 balls) and...
Attempted to solder capacitor onto area with broken pad by soldering to the trace after scrapping the protection offWas able to scrape protection off, but was not able to get solder to stick to the exposed copperEnded up making the situation worseThe...
