Back to the workshop for the revenge of the return of the son of the Vintage Ring Oscillator ! This time with a new ally : the ceramic capacitor ! TL;DR : it's 60% faster ! But the V/F curve might look different from @Tim 's experiments... As usual,...
So, the results are different than expected, but that is just fine. I'm running my V200 at 2x the speed it came from TI. For those who are TL:DR with my logs, you need a 1.21 kOhm resistor and an 18 pF capacitor. I never ran the MD5 checksums as I didn't...
LEDs come in all manners of sizes, colors and brightness. To be able to choose the most appropriate ones, we need to know what are they going to be used for. For this purpose, we did some market research on UV curing glues. After checking the datasheets...
Announcing a major new capability: CylinDraw makes for an excellent paper plotter! The hardware needed to enable this capability only requires the addition of a large tube to wrap the paper around and two rubber bands to secure the paper in place....
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...
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...

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... ----------------------------------------------------------------------------------------------------------...
Now we wanted this display to look really sweet since it will be on our office wall for some time to come. To make it look gorgeous we decided to make the frame out of white foamed PVC board, and the front diffuser out of 1/4" thick white acrylic.First...
We preempt this week’s Hacklet to bring you an important announcement.Hackaday.io got some major upgrades this week. Have you checked out The Feed lately? The Feed has been tweaked, tuned, and optimized, to show you activity on your projects, and from...
Blinking LEDs are good. Moving, spinning things are good too. Put them both together and you get a Persistence of Vision (POV) display. Hackers have been building these displays for years. This week's Hacklet focuses on some of the best LED POV displays...
Just about every hacker, maker and tinkerer out there received their early education the same way: A screwdriver in one and a discarded bit of electronics in the other. There is no better way to find out how something works than cracking it open and...
The brain is the most powerful – and least understood computer known to man. For these very reasons, working with the mind has long been an attraction for hackers, makers, and engineers. Everything from EEG to magnetic stimulus to actual implants have...
