On my TI-89, one of the battery contacts on the PCB was heavily corroded and it took a good deal of time and heat to reflow solder to make a new pad. I did this to the V200 as a preventative measure too, but I guess I heated up the nearby fuse to where...
I have continued debugging the hardware mock-up. The fundamental target was to program a simple RPN calculator UI with 6 operations plus a number of scientific functions. The integration with BASIC will come later, after all the hardware components are...
MethodThe idea is simple, just build the SDK in normal Dual Core configuration, but pin all tasks to the first core. We then can run a task on the second core which should (in theory) run uninterrupted by everything.But: We can't be sure nothing is running...
First paper: Elastic wave modes for the assessment of structural timber: Ultrasonic echo for building elements and guided waves for pole and pile structures (DOI: https://doi.org/10.1007/s13349-014-0087-2, though that goes to a paywalled copy) by Martin...
Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....
See Update BelowContext being more that of the puzzle of cases not one case "to rule them all," but I digress. The past week I've been going through a few catalogs to find an enclosure for D-DAQ's mainboard. Previously, the PCB's form factor was based...
Edit: See also More 2369, with more caps !With a sporadic and limited access to the workshop (at last !) I can finally try new ideas ! I have meanwhile received 9K PMBT2369 in SMD but I decided to use the old stock of 50pc 2N2369A in metal can, that...
Stephen : Alright, let's get rolling. A BIG hello to @Parker for joining us today Parker : Howdy everyone Stephen : @Parker, why don't you kick this off by giving us an introduction of who you are, what you do, and what...
Hardware testing is complete on all the jump and branch instructions. So that's the first 8 out of 256 instructions tested! The next 24 are loading operands. These should work fine since the jump/branch instructions are also loading operands in order...
Thursday, 06/07/2023, 12:40.(I wrote this project log before copy-pasting it here) Anyway, back to DIY electric motors: I can't simply use two 10:1 reduction ratios (which would give 100:1 in total) simply because if I want to reach 30 rpm with...
Jasmine Brackett Hello Everyone. Welcome to this week's Hack Chat! !!!Bhavesh Kakwani WooShulie: Welcome!! We have tons of questions in our sheet already! https://docs.google.com/spreadsheets/d/1ZHahHN4kU0YBjMgrZMU9ntrmdDD8JOUmpHX2mR6Ok0w/edit#gid=0Jasmine...
21/07/2023, Friday, 10:16. For some reason this last week got me too lazy to do anything at all... Well, I will just leave this here and see what I can think of... ----------------------------------------------------------------------------------------------------------...
Simultaneously designing top-down and bottom-up until your designs meet in the middle to produce a functional result. →InsertImageThat sounds like a horrible idea.→InsertImageFor this project, this was the only design strategy that made sense,...
Hackaday and Adafruit have joined forces to present the Raspberry Pi Zero Contest. A great contest is nothing without entries though. This is where the Hackaday.io community is proving once again that they’re the best in the world. The contest is less...
One of the best ways to teach electronics and programming is with hands-on learning. Get the concepts off the computer screen and out into the real world. Students of all ages have been learning with robots for decades. Many older Hackaday readers will...
